Product Overview


More Than A Sports Drink.

Support Muscle
Protein Synthesis*

Enhance Performance*


Lose sweat, not performance.*
  • Final second. Final set. Final yard.
  • Gasping for air and dripping with sweat.
  • You’ve practiced. Planned. Prepared.
  • But none of that matters - if your body isn’t ready.
AminoFast: Drink it during your workout.

AminoFast is the go-to intra-workout elite athletes use to shatter their personal bests.*


Because AminoFast has fast-acting, long-lasting carbohydrates, and branched chain amino acids that provide you with the energy your body needs to conquer even the most grueling workouts.*
AminoFast has quality ngredients that you just won’t find in a corner store sports drink.* Now you can train at 100%, and stay that way - without risky stimulants and the uncertainty that comes with them.*

Stop the soreness.*

Scorched quads from those heavy squats? Throbbing shoulders from that last at bat? Glass knees from your last set? It’s no secret. Soreness stops even the highest level athletes from performing their best. AminoFast provides a vital combination of BCAAs and vitamins that help support recovery from exercise.* Because let’s be honest - your workouts deserve more than just “bearable”.

More than a sports drink.

“Sports Drinks” are overloaded with refined sugar.
AminoFast fuels your energy with Cyclic Dextrin®, a high-quality carbohydrate that supports energy and helps maintain muscle mass.*

“Sports Drinks” may re-hydrate you - but what if you’ve lost more than just water?
AminoFast has a BCAAs and high-quality carbs to refuel your body and return you to optimal performance.*

“Sports Drinks” are loaded with caffeine.
AminoFast isn’t competing with your morning coffee. In fact, it doesn’t have a single milligram of caffeine. Why not? Because in the middle of a workout, caffeine is one of the last things you need. So don’t drink it when you wake up. Drink it when you workout.

“Sports Drinks” taste great, but that’s because flavor is their first priority. After all, they’re made for guys who spend more time talking than training - and that’s not you.
AminoFast tastes great too, and that’s because we didn’t stop until we got it right. In all honesty, flavor wasn’t the focus with AminoFast’s formula - but we’re willing to bet you’d never guess that.

What your sports drink is missing:
BCAA Matrix:

AminoFast has a massive 6-gram serving of free-form BCAAs (leucine, valine, and iso-leucine) in a 2:1:1 ratio.* This ratio has been shown to stimulate muscle building and help prevent muscle breakdown during exercise.* So if your goal is to build muscle, maintain energy during your workout, and support recovery after training, AminoFast’s BCAA Matrix is essential.*

Cluster Dextrin®:

Each serving of AminoFast is formulated with 15 grams of Cluster Dextrin®, a trademarked carbohydrate that goes to work faster, and stays working longer than regular simple sugar. For you, this means more energy, and more of it!*

Stimulants, fillers and sugars? Zero.

AminoFast has no stimulants, no fillers, and no sugars. But what it does have is an ingredient you won’t find anywhere else - one of the most expensive carbohydrates in the world.

Cluster Dextrin®

Cluster Dextrin® is a powerful, highly-soluble cluster-structured glucose polymer created through a proprietary enzyme sourcing process. Its ultra solubility allows it to exit the gastric system significantly faster than simple sugar.

Cluster Dextrin® is an important reason why AminoFast supports better performance, faster recovery, and more energy than your corner-store sports drink.*

Better By Design
Real products from real people.

“Optimal performance during long duration and/or high-intensity exercise continues to wane over time, while your muscles begin to be degraded as a source of energy. A sugary sports drink is not going to cut it. AminoFast™ contains healthy fast-acting fuel to get you through any grueling or long duration activity, in addition to an ample supply of BCAAs to attenuate muscle breakdown during exercise.”*

Taste-10/10. Great pink lemonade flavor. Can't even tell you're drinking aminos or a supplement. Just taste like a nice sweet yet slightly tart pink lemonade Mixability-10/10 No chunks. No grit. Just simply use a shaker and mixed no problem Formula-9/10 Alright guys. 6g aminos is freakin awesome. 3g glutamine is freakin awesome especially since it's one of the most abundant aminos in muscle tissue. I like that there is sodium and potassium which are both required for muscle contraction. I also love that there are carbs- the reason I gave it a 9 is because I wanted to see maybe 25-30g instead of 15g carbs. I think the idea behind this was to give you some pre or intra workout carbs and thats perfect, I would just personally like to have seen more, that's all. Price- ? This is a tough one. This is a pretty pricey supp at $2.40 per scoop (according to bodybuilding .com prices) . That being said, it's a great supplement. I'm not going to give it a 1-10 score because I am an EXTREMELY cheap person, and I don't think that's fair to the company. Price point is a personal issue. You have to determine whether it's worth your money or not. Overall - 9.5/10 Great supplement. Great taste. Great formula. I would definitely use this again. Felt nice to know that my body had the nutrients it needed while going through some hardcore training sessions.

1 scoop of this in a shaker cup dissolves completely, in about 10 minutes. Like other BCAA's I've mixed up, this is no different as the powder tends to repel water and stick on the sides of your shaker at the top. Also, after using a number of times, it's best to dump the scoop into an already full shaker of water than put the powder in first. The water will literally sit on top of the powder at the bottom, even after shaking. I had to turn the shaker upside down and violently shake the heck out of it to get it to mix up. No, my shaker wasn't wet when I put the powder in, I make sure it's nice and dry to avoid stuff sticking in the bottom. This just repels water. That aside, 3 sets of 10 reps hard shaking will get the job done. When it is dissolved, it is completely clear and looks just like water with a slight blueish tinge. Now that's some high quality! The taste is fantastic, like a mix of lemon starburst and Countrytime pink lemonade in a slushy flavor. Yeah, like that. Awesome flavor. I used this without a preworkout or anything a couple times just to see what it would do for energy levels and it didn't let me down at all. The carbs did their job, allowing me to finish whatever workout I was doing that day without a problem. Hydration was excellent, but I did find myself finishing off my 20oz shaker of it before my workout was complete, probably because I was more or less drinking it than sipping on it. Recovery is right there with the best recovery products on the market. Minimal soreness if any the next day no matter how hard I pushed it. I did not have any gastric issues, indigestion, cramps, or anything unpleasant from this product. AminoFast's marketing and claims is backed by this product in every way. It makes a fantastic intra and post workout drink and will definitely aid in your performance and recovery. The only negative I can find is the price. $60 for 25 scoops/workouts. Now, if you let this be the only thing you take, then yeah, it can function as a pre (the carbs really do give you energy), intra (bcaa'a) and post (glutamine) workout supplement, saving you from buying 3 separate products. This product CAN do that.

I got to try a tub of this new flavor courtesy of the Blue Star crew. First taste was "is this like the mystery flavor kool-aid?" So much going on that you don't know what's going on. After quite a few scoops I've narrowed it down to something like a frozen lemonade with cherry (like a white cherry icee maybe). It definitely has a tartness to it. Mixability is fantastic in 16oz water IF you add ice after or no ice at all. If you put ice in the cup first, you're going to get mad clumps. Or you could mix it in a blender which made for a great slushee - not so much intraworkout, which is my primary use. Most importantly - the profile. I have only used one other intraworkout with 3g leucine (2:1:1 BCAA of course) and 3g glutamine and is certainly welcome. With the added 15g carbs and electrolytes it's like adding a high powered (and better) gatorade to my BCAAs. Certainly saves me time and trouble. Between the two products, I save this for my heavier days (back and legs) as the added carbs really help me make it through without dying. Awesome and well-thought out product.

I received a tub of AMINOFAST through a Blue Star promo. Thanks Dazed for the opportunity to review. Flavor: WHITE FREEZIE Taste: It is easy to see why this flavor is a popular one. This is delicious! With the first sip, you are immediately hit with a tart flavor. If I had to break down the flavor, I would say it could be compared to a combination of citrus and some white grape juice. It almost has a lemonade flavor as well. It’s not sweet, but I love it. I also love that there’s no frustrating aftertaste to deal with either. I give this flavor a 10 out of 10! Benefits: BLUE STAR AMINOFAST is designed to: - Provide an enhanced BCAA delivery system - Hinder muscle breakdown during exercise - Give you a fast delivery of long sustaining energy - Ward off post-exercise muscle soreness (DOMS) Mixability: Zero mixability issues here. I use approx. 20 oz of water in a blender bottle and it works great. There also was no settling of the powder after it’s mixed. I give mixability a 10 out of 10. Profile/Label: The profile here for the most part looks great. There’s a combination of 6g of Leucine, Isoleucine, and Valine in a 2:1:1 ratio. On top of that, the added electrolytes are a nice touch. Each scoop of AMINOFAST, also includes 15g of carbs. I love carbs for workouts, so this is definitely something I enjoy. I like that they used cluster dextrin as well. The only thing I would like to see broken down a little more is the “XD Delivery Technology Complex”. There is a combination of 79.01mg of Fumaric acid, BioPerine, Astragin, Sodium R-Lipoate, and Succinic Acid. However, I’m not sure how much of each ingredient you are getting. So I give the label a 9/10 with the XD Complex being the only thing I would like to see more transparency on. On AMINOFAST, I felt hydrated and great during my workouts. Because I have been doing some heavy workouts, there has been some muscle soreness. So, I can’t speak much for the DOMs. But this isn’t something I would lose sleep over. To me, this product has what I want. It gives me fast absorption, added electrolytes, added carbs, and plenty of BCAAs. I give this product a 10 out of 10. Jump on the BCAA bandwagon and check it out.

Apr 07, 2017

Overall, this is a great BCAA product! It has a hefty dose of what you are paying for (BCAA'S) with additionally beneficial ingredients like electrolytes and the delivery complex. Prior to this product I was NOT a fan of dextrose, but I found the product to give me a bit of a boost and help power through long/hard leg workouts. The flavor is INCREDIBLY sweet, so that will be a matter of taste preference, but you could seriously mix one scoop with a full gallon and still have a pretty potent flavor. If you are looking for a solid intra-workout that will give you a little extra boost this is a great option!

To start, I'll mention that I'm doing a push/pull/legs routine, and I've had two workouts of each using Aminofast. I also write down all of my lifts to help progress week-to-week. First off, the watermelon flavor is exactly like a watermelon jolly rancher. It's really great and refreshing during a workout. It mixed easily in just a water bottle with no shaker ball. I, like other users, noticed great pumps while using aminofast. I used 1 scoop on push and pull days, and 1.5 scoops on legs. An increase in endurance was the most noticeable for me, and also the most important, IMO. I noticed extra reps, specifically an extra set of pullups that I usually need assistance for. I highly recommend Aminofast.

AminoFast is a seriously outstanding product. it does everything youd expect from a quality Amino and SOOOOO much more. when sipped as an intra, AminoFast also provides fast acting carbs to keep your body fueled and a re-hydrating blend to keep you hydrated. the Watermelon flavor is very refreshing and a pleasure to drink. Blue Star has done a great job here producing a superior product...well done!

Feb 16, 2017

A true homerun from Blue Star with AminoFast. I use a scoop of this as my intra-workout supplement and it certainly has helped my performance in the gym. This supplement helps keep me hydrated while I train and has definitely helped to eliminate nearly all of the DOMS that I typically feel the following day. The cluster dextrin also provides me with additional energy when I am in the gym so I'm not crashing mid-way through my training. Excellent results with this top-notch product!

Feb 16, 2017

Aminofast has quickly taken its place at the top of my list of favorite Amino products. Aminofast not only helps with recovery it also supports muscle growth, increases performance and hydration! the Pink Lemonade is one of the best ive had and is so refreshing when sipped throughout a workout. Aminofast is a hands down winner!

Feb 14, 2017

AminoFast is just another in a long line of outstanding products by Blue Star Nutraceuticals. the quality of these products are incomparable and AminoFast is no different. tis is so much more than just an amino drink. AminoFast combines fast acting carbs, BCAAs and a Re-Hydrateing blend to give you the best hydration and recovery that youve ever experienced. i got the Watermelon flavor and it was very nice and refreshing. this is really a superior product well worthy of the Blue Star label.

Feb 14, 2017

I was lucky enough to get a tub of this from Gym God to try out and was super excited reading over the ingredient list and about the Pink Lemonade flavor. Once again Blue Star went above and beyond with this, first off the flavoring is top notch not too overly sweet but just right in a full blender bottle and then an extra 8 oz to get that last little bit through your workout. Best of all so far has been the actual results with the product, gone are the sore days after, no energy throughout your workout etc. The Cyclic Dextrin definitely plays a key role here in helping you out, no caffeine is perfect b/c most of us already take a pre workout so for an intra workout this is perfect. No fillers etc means you know what you're getting here nothing but high quality products every time. Blue Star knocks it out of the park once again!

Fantastic product. Taste of the Watermelon flavor is awesome, like a jolly rancher. It can be a bit sweet if you don't use the right amount of water, i found 1 scoop in 24oz to be perfect. I was interested to try this, being on a keto diet. I was hoping that I could use this as a carb-up for my workouts while remaining in ketosis and thankfully, there was no issue. Over two heavy arm days, recovery and endurance has been great. Can't really ask for a better product than this.

  • 10 Watermelon

First off, many thanks to Blue Star Nutraceuticals for hooking me up! I received a tub of watermelon. Cluster Dextrin is not something that I have tried before, but it had some interesting benefits which were fully felt during my workout. I took a serving of this during the day, much before my work out, and another serving during it (mixed with some PWO). The taste is excellent, almost like a Watermelon jolly rancher. With the PWO however (lemon), the taste got a bit too tart, but that's on me for mixing things together. DOMS-wise, I still have some the next day after my workout, but definitely not as much as usual. Great product all in all!

This is the best tasting watermelon supplement I have ever used!!!! AminoFast is tasty! Love to sip on this intra-workout!! Definitely going to buy more!

Feb 27, 2016

There has to be some sort of child labor law broken here cause taking Aminofast is like drinking a blue sour patch kid that goes straight to work repairing muscles to be bigger and bigger. Simply amazing the difference in recovery time compared to not having it. I'm no fan of leg days just like anybody else but when you know you're not going to be out of commision for an entire weekend because of a single muscle group, makes any excuse to skip invalid. You won't have to worry about trying to take arm day easy cause you have a home project or football game with the guys the next day. Train hard knowing recovery has never been easier.
