Product Overview

Amino IV - The Most Versatile Amino Product

We live in a day and age in which optimizing performance, recovery, and results are integral to every meal we eat and supplement we consume. We don't just consume post-workout protein and call it a day...we've learned from science that taking separate, free-form amino acids can give you an extra edge to take your progress to the next level.

Amino IV: A BCAA product with added benefits to take it beyond just another BCAA.

You spend all the time and money working hard and eating right...why sell yourself short on your essential supplements?

High Leucine Content - 5 Grams per Serving!

Countless research has shown that leucine is the key amino acid for activating muscle protein synthesis. Amounts as low as 1.8g (in combination with EAAs) have shown to be effective, with more commonly researched amounts around 2.5g (in combination with BCAAs), and the high amounts in the 3.6g range (alone, and in combination with EAAs).*

We don't mess around with Amino IV -- 5 grams of leucine per serving, and 30 servings per bottle makes Amino IV a cost effective leucine source, before we even get into the perks of the rest of the formula!

Unlocking the Power of Leucine-Enriched EAAs

What is every amino product built off these days? Branched chain amino acids (BCAAs). BCAAs are key ingredients to consume no matter what type of athlete you are: Bodybuilding, powerlifting, long distance runner, or sprinter. If you work your muscles...BCAAs should be a go-to supplement.

But the majority of the BCAA products on the market are just that...BCAAs, not a whole lot else. There are a few industry-funded BCAA studies out there with good results. But we feel these products are missing something essential...literally!

The body runs off what we call Essential Amino Acids. These are amino acids that your body cannot make on its own. They must be consumed via diet. You see, when your body goes to make new protein, like the protein that make up your muscles, it requires that all of the 9 essential amino acids be present, not just the 3 BCAAs.

Your body starts by making muscle protein to build muscle mass. It incorporates the BCAAs into the growing protein chains, and then your genetic code calls for an essential amino acid. So what happens if you don't have EAAs present?

  1. The new protein is terminated. You simply do not benefit.
  2. Your body breaks down a pre-existing muscle protein (known as “catabolism”) in order to get the missing amino acid. The net effect is loss of muscle mass.

Now most of us should have sufficient EAAs if we are on high protein diets, but if you are going to be taking a supplement with leucine or BCAAs, why just assume you have sufficient amounts already in your body? We created a product that provides each essential amino acid in every serving.

It's not About the Ratio!

If you are an “amino-holic” than you have probably come across advertisements and claims about what the best “BCAA ratio” is. Some companies claim a 2:1:1 ratio is the best because they say it's the only research backed ratio. We are here to tell you that is simply not true.

In fact, one of the most recent and powerful studies, an independent study by the US Department of Defense, was done on a blend of EAAs. One consisted of a 2:1:1 ratio of BCAAs in the blend, and the other, a leucine-enriched blend that had a ratio of 4:1:1.

OMG! Does this mean a 4:1:1 ratio is better than a 2:1:1 ratio?! No...what it means is that the ratio is not important. What is important is that you have a high leucine content, and sufficient amounts of all other EAAs in your diet. That is why Amino IV is a formulated high leucine-enriched EAA product.

Taurine & Electrolytes

If you are a hard-working, sweating, and fatigued athlete then you are probably more than familiar with those sugary sports drinks with electrolytes. But now you are more educated than the days of when you would down those by the bottle. Now you avoid them because of the high amount of table sugar in every serving...but the downside is you have a tough time getting the electrolytes you need.

To continue to versatility of Amino IV, we have added electrolytes and taurine to every serving. Consider Amino IV your guilt free sports drink with muscle in mind.

I take this intra-workout and I feel it gives me extra endurance! I also notice my recovery is a lot better when I'm using it consistently versus not. I look forward to drinking it because it tastes so good :) The Raspberry grape and Mango splash flavors are my go-to!

This product was so affected by heat or moisture that I haven’t used it since the first time. It was really clumpy and didn’t mix well. The flavor was alright but tasted almost chemically. I love this brand protein wise, but my first time using their aminos was a bummer.

This item had severe moisture issues when I received it. It was clumpy and doesn't blend well into water upon first shaking. It needs to sit for at least 5 min before everything is incorporated. The flavor was okay... nothing special. I wouldn't buy again.

These exceeded my expectations. With true BCAAs they can have a bitter aftertaste and I was fully expecting that but did not find that to be the case. The only reason I didn't give them a 10/10 is because I thought the strawberry could have been a bit stronger. I just purchased the watermelon and cannot wait to try that flavor, too. Another PEScience product that I can ad to my staple collection!

These Aminos have saved my life during prep! Mango Splash is my absolute favorite, but watermelon is a very close second. I haven't tried the other flavor yet, but probably will soon!

This is excellent intra-workout fuel, the ingredients speak for themselves (5g leucine, essential aminos, electrolytes, plus a hint of taurine! I'd like to see all natural flavors/sweetening top off this already dye-less formula! Thanks PES for a very tasty amino blend!

PEScience makes the best BCAA's out there in my opinion. I have tried many samples of BCAA's, but once I tried Amino IV I fell in love! I love all 3 of these flavors equally, but I think Strawberry Breeze is my favorite! You can't go wrong with any flavor though.

PES slashing their formula for Amino IV not once, but twice, has left the product wanting. While still competitive to the market, it's a shadow of its former self. This holds true foremost in taste. They REALLY need to bring back Cherry Limeade. While Mango is a bearable substitute, it doesn't even remotely compare. I used to drink this throughout the day simply because I enjoyed the taste. I now keep it strictly to intraworkout. The moment they reintroduce Cherry Limeade, I'll be back to stockpiling Amino IV. Until then...

I got a one serving sample packet as part of the Amino IV promo, and holy crap I'm glad I got to try this. Watermelon WAS DELICIOUS. IT WAS SO GOOD I ADDED MORE WATER JUST SO I CAN PROLONG THE SERVING. I didn't really notice any difference, but then again I drink a protein shake one hour before working out, so I usually get my BCAAs before working out. But I did feel like I was less tired, not sure if that was a placebo effect or not. Nonetheless, I loved it!!! I will definitely buy a tub once my current tub of Intrabolic runs out.

I am not a huge fan of mango. My wife is. We both tried this and we both enjoyed it. Super easy to mix, not too sweet and not too bitter, plus a good amount of electrolytes for an amino drink.

An excellent dose of leucine. The primary building block BCAA along with a good dosing of EAA make the product great for Fasted training or between meals. I train early in the morning so taking in even a protien shake is hard sometimes. This product delivers in so many levels, flavor, effect, price. Mango Splash is delicous. And mixing is easy, there is some foaming due to the massive dose of Leucine. Would recommend to anyone looking for a great Intra product!
