“Another awesome and effective blend from Gavin and the interstellar team. ANTI-FATIGUE does exactly what it sounds like but in a powerful yet subtle way. This is no sugar based monster or red bull energy, it will hit you without realizing and you’ll have a natural energy and alertness. I was anxious to try this blend, and when I did I wasn’t sure if I could really feel any difference until I realized I was half through the work day without any muscle pain or tiredness. I really love the subtle energy boost I get from this blend and it’s instantly going into my list of must haves. Love mixing ANTI-FATIGUE with GAINZ for a gym session, and you’ll notice you can push those few extra reps like it’s nothing. If I’ve got a long day of heavy labour at work, I just take some ANTI-FATIGUE with my lunchtime coffee and other blends, and while the rest of crew is having fast food sweats and lethargy, I’m gaining a clean natural feeling energy boost for the afternoon. It also works well to eliminate brain fog and slow mornings. Overall it’s another 5 star blend from Interstellar and I highly recommend it for mental or physical energy and alertness -Matt”— Matt Desmarais · ✓ Verified customer★★★★★
“Do you want to have a body of a Greek god and not inject yourself with poison well GAINZ is that key. Gainz is a natural muscle building machine, all plant based. My growth on GAINZ has been exponential and my recovery time has been quick allowing me to workout everyday without fatigue. I have been patient for a blend like this and now it’s finally available to the public. This blend will literally boost your confidence and physical appearance. Before Gainz I couldn’t even do push-ups optimally or finish sets but after taking Gainz my mind gets clear and my reps and full and my form is perfect. I train calisthenics with GAINZ which feels amazing, my pull ups push ups, sit ups, and squats are done fully without any pain. I also take Gainz with BCAA to help with this muscle recovery on a faster rate. I’m able to progressively overload my workouts every week and my workouts just overall feel amazing which in turn makes my day better. Looking in the mirror I’ve been seeing massive progress and GAINZ, my arms look bigger, chest, and legs. Thank you Gavin for creating Gainz I can just imagine how crazy this blend will be once you have perfected it as this is only the prototype sample. Building muscle has never been so easier, at this point people might think I’m juiced up but little do they know I’m all natural with the testosterone level of a Greek god. More Gainz equals more confidence and in turn makes men more masculine at their core which is needed in our society. To much pussys walking around man who can’t even do a push up but with Gainz and consistency this can be changed and we will finally have a better world with better men.”— sabbir rahman · ✓ Verified customer★★★★★
“GAINZ is not one to be messed around with, people think Im on roids! The way I walk around the gym after first exercise, priceless haha. The muscles themselves grow fast and very strong, haven’t seen such increase of strenght from times I was taking testosterone! I can’t say for sure but I feel Gainz works like a pre workout too, I can feel that it destroys my laziness and there are no more excuses not to go! Im jet to try it with muay thay but Im pretty sure I will totally crush the workout and look amazing doing it Gainz keeps all my muscles in tact while Im nicely burning fat, something no diet or supplement can give you, you either burn, or bulk. Gainz changes the spectrum so you can enoy beach body, look good, muscles are constantly pumped (not just while working out), you burn fat, strong as Papaye, elevating wherewer you are, be it gym, running or whatever you do physically! 10/10 from me personally, Im not lettng my supply dry and I’ve already added it to my life-time cycle on Interstellar blends ;)”— michalfilipkowski · ✓ Verified customer★★★★★
“GAINZ review: Of all the blends, I believe this one has the quickest outward effects than any other! I was absolutely blown away by how quickly your strength, endurance, and muscles enhanced in just over a week! It can be a little scary after building this blend into your system and witnessing the amount of strength that incurs. Even when you’re not lifting weights, you will still notice yourself getting stronger and stronger. If you’re doing prolonged fasting, taking this blend before (if dry fast) or during (if fasting with blends), your muscles will have no appearance of atrophy. Another benefit that is seldom mentioned is the fact that your vascularity seems to be much more prominent. It’s as if that GAINZ will increase your performance in whatever athletic activity you do. Whether that’s weightlifting, boxing, running, jump rope, etc. FASTER, STRONGER, BETTER! For this reason, it’s very important to train hard in whatever area you prefer in order to get the most out of the blend. But again, even if you’re fasting it will still preserve muscle! On GAINZ, going to the gym before doing carpentry all day in the sun becomes a piece of cake. Your level of work output is increased without you even being phased by it. There have been times where I was taking it for months, and times where I was not taking it for a period of time, and the difference is night and day. The great thing about GAINZ in comparison to other “muscle supplements” is that it does not raise your mTOR levels through the roof! This blend is a must have and you should always be stocked up on it. Nothing else comes close!”— Dylan Cobb · ✓ Verified customer★★★★★
“The GLP-1 activator!!!! The FIRST day I tried this, I fasted 22/2 and in my feeding window I tried to eat a small very low carb meal, and I could only eat half of it!!!! It truly DID keep the hunger waves at bay during fasting, I am losing body fat steadily and so excited to receive my GAINZ blend this week and get started adding some lean mass as well. This blend is a must have if you struggle with hunger/nausea and lethargy during fasting and atop the other blends I have purchased it’s like icing on CAKE!!!! Gavin has yet another masterpiece in this GLP blend, I’m a week in, and stoked about the results I’ve seen so far and looking forward to hitting the goal I’ve set for myself and then using the blends for support in maintenance!!! Thanks again, Gavin <3 Jackie Rae”— Jackie Rae · ✓ Verified customer★★★★★
“GAINZ Review GAINZ is a must have if you’re over 40. Especially for men. I’ve been losing muscle mass and strength since around 45, and it has accelerated in the last few years (now 52). If I don’t workout constantly, then I immediately start getting weaker and less flexible. GAINZ is the only thing I have tried which has reversed that. In the first few weeks of starting my loading dose (1 tsp per day with GrapeFruit Juice), I started to feel stronger and workouts got easier. My muscles felt more flexible and energized, like the years were melting off. When I started GAINZ, I hadn’t been to the gym regularly for several months because of work. So when I started going back to the gym on GAINZ, the workouts were significantly easier than I remember, and I was back to my old levels in a few weeks. Normally, it would have taken me around 2-3 months to get back to my old levels after such a long slack-off period. Happened much faster and easier with GAINZ. I also noticed a definite decrease in blood pressure, which is good as I’ve had acute high blood pressure for years and years. The other blends, especially Thermo, have helped manage this problem massively, as well as giving up seed oils. But as soon as I had been taking GAINZ for a few days, I noticed my blood pressure drop after dinner (when it usually goes up). At the same time, it felt like my muscles were getting more blood going through them. A very marked increase in circulation. I’ve had a similar experience with other workout supplements, but they always increased my blood pressure as well (which is bad for me). With GAINZ, it improved my circulation without the corresponding blood pressure increase! Fantastic! I’ve also noticed increased endurance at work (I do construction). Normally I will get tired after a few hours of heavy work and have to take a break, but with GAINZ I found myself going almost the whole day without rest. Pretty amazing! I also pulled a muscle in my left elbow area a couple years ago (don’t lift a 12 ft countertop by yourself stupid), and it has bothered me ever since. With GAINZ I noticed that this injury didn’t bother me nearly as much. After a couple weeks, I could barely feel it. Actually, I just ran out of GAINZ, and I can already feel the difference after a week being off it. Time to order more!! Another fantastic blend from Interstellar! Two thumbs up!”— Rich Ryan · ✓ Verified customer★★★★★
“Gainz Review Gainz has been one of the most profound blends I have tried yet. When I first began Gainz I had just begun to workout after months off and I was only able to do about 20 push-ups. The first day I took Gainz I was able to do somewhere around 45 push-ups. My mind was blown! I felt stronger immediately and the results showed! After a few weeks my friends noticed that I had visibly gained muscle. Each time I workout after I began taking Gainz I notice a continual increase in both my strength and endurance. Not only do I feel stronger but I don’t wear out quickly either. Gainz is a game changer and I have never seen such quick results with any other workout supplements. I have the energy and power that comes from pre workout with out the crazy rush or the crash! Gainz has quickly become one of my favorite blends and I’m thankful that Gavin has created it! It’s so important that we maintain our muscle and Gainz does exactly that! I have a hopeful outlook on the future now knowing that Gainz will keep me looking and feeling youthful even into my older age! If you’re on the fence about trying any of Gavin’s blends just take the leap, I can testify that it will change your life!”— Scotty Ryan · ✓ Verified customer★★★★★
“Wow!!!!!!! Amazing!!!!! I’ve been taking blends for quite sometime and for the most part it has taking me longer to heal 20+ years of type 2 complications and I’m fine with that as long as I continue to heal. During that time I’ve lost muscle mass BUT let me tell you SOMETHING! GAINZ!!!!!!!!!!! The first week was mega dosing (1 sample was enough) and I just walked. Going into the 2nd week (started my second sample) I started using 5 pound dumbbells. Okay 5 pounds! Working my arms and squatting for my little glutes. At the start of the 3rd week I started to notice muscles on my arms and I can finally for the first time in years feel muscles in my glute area! And this is only doing some exercises at home can’t imagine when I start doing complete muscle work outs. GAINZ along with glucose blocker are the pixie dust of blends for me. Can’t wait to order more and continue this amazing journey with blends. ❤️❤️❤️❤️❤️”— Leticia · ✓ Verified customer★★★★★
“I experienced a quick healing of an old muscle injury on Gainz!! Years ago I healed myself of an inguinal hernia, but the abdominal muscles never returned to how they were originally. So a few times a year when I pushed things too hard in the gym, I would get shadow pains. They were not anywhere as bad as the original inguinal hernia,but they easily disrupted my workouts, and would last for 3-4 weeks. On my loading week with Gainz, I got one of these shadow pains, but instead of hanging around for a few weeks- it was gone in 3 days!! I am overjoyed by my results!!”— Stephen Shiman · ✓ Verified customer★★★★★
“I’ve used various Interstellar Blends over the last 6 years, and in my experience, they’ve not only delivered on the desired outcomes…they’ve blown them out of the water! Whether it was helping me get through my first extended dry fast or improving my overall health and longevity, I’ve always been happy with the results I’ve gotten. But even with my long history of satisfaction with the blends I’ve tried, my experience with GAINZ has to be the most mind-blowingly impressive of them all! I’m not a workout warrior, muscle bound type of guy. I’m 6’4”, and with such a big frame, it can be tough to tack on a lot of visible muscle without spending 8 hours a day in the gym. Based on my previous experiences with blends and the early results others were getting from GAINZ, I figured I’d give it a try. Let me tell you this: GAINZ delivered on every promise made…in spades! In less than a month of use, I’ve added around 4 pounds of muscle, and that’s with no weights, only body weight calisthenics and cardio! My significant other pointed out the size difference before I even noticed it, so I know it’s not just a placebo effect and wishful thinking on my part. I’ve also gotten more definition, and after my workouts, I stay “swole” throughout the day. I’ve developed a more vascular look, as veins are popping out everywhere. Not to mention, my blood pressure is down, my body fat ratio has decreased, and my endurance has gone through the roof. I’m a 48-year-old guy, and this blend has taken years off my age and allowed me to perform like I could when I was in my 20s, with less daily pain and greater resilience. If you’re looking for a way to add muscle, trim body fat, look more athletic, and feel like you did in your 20s, then this is the blend for you! It’s miraculous. You’ll look great, and feel great…and what can be better than that? The other blends will give you longevity, but when you add GAINZ to your repertoire, you’ll get both quantity AND quality! You’ll feel and look like a million bucks! Evan D.”— Evan Duffy · ✓ Verified customer★★★★★
“I LOVE THIS BLEND ITS ONE MY NEW FAV BLENDS IT HAS HELPED TO LOSE SOME STUBBORN BELLY FAT ALONG WITH GAINZ WHICH IS ANOTHER AMAZING BLEND WHICH I HIGLY SUGGEST”— Ronald · ✓ Verified customer★★★★★
“Man I don’t know where to start. Let’s put few things here 1. Im very sceptical (the amount of drugs I’ve tested gives me massive tolerance to everything, theres not many things that work 2. I can’t tell if something is working on me, Im not very perceptive, I don’t remember how I always feel therefore I can’t really compare. Ok so I’ve ordered Pine Pollen and Trinity after reading the testimonials/telegram, Gavin’s youtube, whatever I could find, I know nature cures everything, I know fasting is healthy, I don’t use convencional medicine and Im not scared of headcache or flu etc (f covid) so I knew these blends may be good, I heard about them from my friend who loves them when he fasts and says that they put him in a meditative state when he can work many hours without a break, which is a non brainer for me because Im using my laptop a lot, do boxing, weights, jump rope and Im very active, thing is my memory is very poor and sometimes I lag and sit on instagram too much and do nothing, I burn out like some hard working people do. I’ve never done fasting as well, and these blends works best with fasting, great cause I like challenges! Once the blends came in the morning (thanks Gavin for extra PLUSH sample!) I was already fasted, already had my coffee, so what was left to do is to measure 1/8 spoon of Plush and Trinity and put it in my mouth haha, drank some water and off I go. I got working and could definitely feel energy coming from my spine, also the hunger was easier to deal with, I ate at 1pm that day, where Im usually after 2 small meals, I think that’s incredible! Next day I put 1/4 of a spoon of Plush and 1/4 of Trinity and went to work, haven’t eaten till about 2pm, did about 16/8 there! Next day (today) - day three, Again, black coffee, 1/4 Trinity and 1/4 Plush to my mouth in the morning, drank some water - tastes baddd, went to work and haven’t eaten till 4pm, I just did 20/4, a guy who loves sweets, insulin high all the time, eats much more than he should. Im 91kg and 188cm height which isn’t bad but Im very active, still didn’t like how I look and these blends are incredible with fat loss/not thinking about food/work-mode/undistracted From sceptical mf Im turning into a great believer in those blands, I know that my ‘fuck this I don’t want to be unhealthy and I gotta start working’, helps with that as well but I can be certain that the blends surpress my apetite and give me energy, keep me focused on my tasks you know, which was why I bought them. Im waiting for Autophagy to surpress my appetite even more and help me stop eating those bloody sweets, GAINZ to keep my muscle mass, and Autonomous - to hopefully help with my memory which is pretty bad, very short term memory basically non existent. Once I know how what works I will be posting reviews in relevant sections, I know it’s been 3 days but this shit works trust me, Im excited like a baby for an ice cream to find out how these can help me long term! And don’t think about price, coffee,breakfast, snacks cost similiar to these, and this is pure health, take it easy!”— Michael · ✓ Verified customer★★★★★
“I’ve been using several Interstellar Blends supplements for a while now, and honestly, the difference is remarkable. Trinity has been a game changer for keeping me balanced—mentally sharp, emotionally steady, and overall in a better state. There’s no brain fog, no sluggishness, just a clean sense of clarity. Autonomous takes that to another level, providing me with deep focus and energy that lasts all day without any of the jittery side effects typically associated with stimulants. Rewire hits differently; it feels like my brain has switched into high-performance mode, resulting in less procrastination, fewer distractions, and an overall sense of control. One of the most significant changes I’ve noticed is how much it helps cut down cravings, which has been crucial for me during fasting. Normally, going long hours without food would drain my energy, but with this stack, my mind stays clear, and I don’t experience those intense hunger spikes. It makes fasting feel effortless. On the physical side, Titanium and Gainz have proven to be a powerhouse duo. I’ve noticed faster recovery, better endurance, and real strength gains, which is especially important because fasting alone can sometimes make it challenging to maintain muscle. Gainz has really helped with that; it feels like my body is in a constant state of growth and repair rather than breakdown. Pairing that with Pine Pollen, I experience a natural, steady energy throughout the day, and I definitely notice a hormonal boost in terms of strength, drive, and overall well-being. My workouts feel more powerful, and I’m not hitting walls the way I used to, even when training in a fasted state. The fact that I can fast for extended periods, stay energized, and continue to make progress in the gym speaks volumes about how well these blends are working. Additionally, the long-term health and aesthetic benefits have been equally impressive. Plush, Apigenin, and Super Tonic Hair have noticeably enhanced my appearance and overall recovery. Plush has my skin looking much better—brighter, healthier, and more youthful overall. Super Tonic Hair has made my hair feel stronger and thicker, which is something I never really focused on before but now deeply appreciate. Apigenin has been a sleeper hit for me; it helps me wind down at night, improves my sleep quality, and I wake up feeling more refreshed, which is crucial when fasting and training. Altogether, this stack makes me feel like I’m operating at a higher level—mentally, physically, and even visually. While it’s not the cheapest option out there, between the fasting benefits, muscle retention, cognitive boost, and overall well-being, it has easily become one of the best investments I’ve made in myself.”— Nushratally Emambux · ✓ Verified customer★★★★★
“Wow, sorry I almost forgot about Gainz and Rewire! After about a month or so the results I got from Gainz was great. I have a clean diet so that helps but my muscles actually grow and get way stronger too after taking it. Rewire is one I love to pair with Trinity and/or Nebula for the days I have to buckle down and really get a lot of work done. I work on the computer and let me tell you, nothing is going to be able to break your focus unless you want it to. I love that feeling. Time just flys because your so focused on the project getting a mountain of work done. Solid solid products for sure too. - D”— Dennis Forbes · ✓ Verified customer★★★★★
“FORCE FIELD GAINZ JING FORCE LIVER REGEN. LUNG P. SABRE T. TITAN., organ specific regeneration & rejuvenation. All herby in taste. Samples Tested. Taken while fasted with grapefruit to enhance potency. Gainz in particular has an aloe vera type of flavor. Sabre Tooth is “light” and has less of an atomic density to it. Taken dry by the teaspoon with varying dosages day by day. With regards to Force Field in particular, I look forward to the REDUCTION of the FREE RADICALS that run rampant in the body! This reduction in free radicals, leading to Which would be felt when taken at larger doses in conjunction with the simple genius of PEEL (combating oxidative stress as an antioxidant) would in fact be powerful catalysts to destroy inflammation. ADD Ascendance and you’ll be on your way towards living life with less pain and less inflammation (oxidative stress / too many free fradicals). When taken together or separately, you can expect to enhance the basic performance of the organs. (in terms of strength, Gainz reigns as the supreme blend). As for homeostasis & regeneration, Jing force, Liver Regenerator and Titanium are absolute MUSTS. Sabretooth is a great aidto the gums, which has restored healthy pink gingiva. A reduction in Trapezius /muscular inflammation and the elimination of the “knot” in the right TRAP (thank you FF Gainz AND Titanium.. To increase antioxidants, thus protecting skeletal muscles from damage done by free radicals (prevention). Reductions in pain, again in the upper back trapezius area (particularly the skeletal muscle on the right clavicle). Blood purification (liver regen). Tangible Example: 6 hours of Laboric performance, 5 minute break, completed with energy to spare. ¼ tsp taken twice per day. Enhanced drive. Being able to physically exert until the point of “nervousness/ shakiness”. Conscious Presence. Full breaths with no coughs. (Loss of asthma related symptoms & use of inhaler is a thing of the past (2019). Bone Marrow cleansed, hardened with increased resilience (ex. Bumped tibial bone into an iron rod with no pain, regardless of bleeding). Increase in muscle tone & definition. Forethought: Continued performance at a high level is to be expected. Restoration of full capacity to perform. The science is absolute. Thank you to the interstellar team for the restored performance! Grateful to be revived! I plan on utilizing these blends indefinitely into the future. Next, I’ll have to prioritize loss of fat in hard to reach areas, keep the fat off, protect and enhance the performance of vital organs, while also building muscular strength.”— Pablo Arteaga · ✓ Verified customer★★★★★

“One month ago I placed my first order and boy was I not disappointed! First of all, I can feel all of them, each has a very pronounced effect. Supernova makes me super focused and alert, Gainz significantly increases my muscle mass and strength, the rest just make me feel better in general. I’ve been experimenting with all sorts of different supplements and practices over the last 2-3 years but I have never felt such prominent effects. Although, in this review I’d like to particularly highlight Super Hair. I’ve been dealing with slowly receding hairline since I was 20. I started fighting it right when it started, doing all sorts of things from natural toos like microneedling and rosemary oil to more kind of pahrma things like minoxidil. Last few years even though I’ve been doing a lot, the receding hairline started to win the battle. I’ve been seriously thinking about doing hair transplant in the next couple of months. Hard to put in words how amazed I was with the results I got from Super Hair. Never have I ever seen such a FAST and PRONOUNCED effect. One week in I could see new hairs growing and old ones getting thicker. No other hair solution or compound works that fast. Minoxidil takes around 8 weeks to see the first tiny results. Hats off to Gavin for creating such a powerful and natural solution. 👏👏👏”— Konstantin K · ✓ Verified customer
