Bringing Old School Back

Pure BCAAs are everything you need to rebuild, repair and trigger lean muscle growth. ISO-Amino is a throwback to the old school BCAAs that are just that, pure isolated BCAAs. No added marketing fluff, prop blends or underdosed “everything & the kitchen-sink” formulas that only cushion the manufacturers wallet.

The Fat Burning, Muscle Building BCAA Ratio

BCAAs in a 2:1:1 ratio have been clinically studied and PROVEN to effectively aid in muscle repair, growth, muscular energy and even fat loss. BCAA products with inflated ratios of 8:1:1 or even 10:1:1 show no added benefit over their 2:1:1 counterpart. So why the 2:1:1 ratio of BCAAs? Simple, “if it’s not broke, don’t fix it.”

Baylor University Proves 2:1:1 Ratio

Scientists from Baylor University gave college-age men either a leucine supplement, a BCAA supplement or a placebo before and after a leg workout. They discovered that while leucine increased muscle protein synthesis after the workout better than the placebo did, the BCAAs increased protein synthesis even better than leucine and the placebo. That’s a big reason to stick to a 2:1:1 ratio when it comes to BCAA supplements.

An Amino That Tastes Good?

It has nothing to do with science or efficacy – but it’s important to enjoy what you spend your hard earned money on. We take flavor & mixability very seriously. This is where ISO-AMINO stands as the clear leader. MAN Sports has made monumental advances in flavor systems to provide extremely unique, one-of-a-kind flavors.

Extreme Energy Boost

I bought the ISO Amino and the CLA. This was my first time trying it and it helps me a ton at the gym! I can finally finish my workouts! Highly recommend and very high quality!

Rose champagne

So I had dorks first, and it tastes very grape like, and I'm not a fan, so moved to rose champagne, although it's fizzy and they both have a weird after taste, love this flavor much more!

Perfect in any flavor!

Absolutely LOVE LOVE LOVE these aminos! I have them in multiple flavors (rose champagne, mango, Dr. Pop, pink lemonade) and I can not get enough! These are a great item to replace soft drinks and curb your sweet tooth, and really help you recover from that intense workout!

I am obsessed with Fallon’s Dr. Pop! It tastes just like the real thing and curbs my sweet tooth. I’ve been working out hard lately and have not been worn down or overly sore since starting ISO Aminos!
