Product Information


XR Series™ BCAA Advance XR™
  • Advanced BCAA System to Spare Muscle Breakdown & Preserve Glycogen*
  • Immediate & Sustained 6 Hour Extended Release Anabolic Leucine
  • OT2™ Technology for Advanced Muscle Protein Synthesis*
GNC’s superior Pro Performance® XR Series™ BCAA Advance XR™ is uniquely formulated to help athletes receive immediate release of muscle fueling Branched Chain Amino Acids (BCAA), plus a longer lasting supply of anabolic Leucine. Leucine is the key BCAA shown to impact muscle protein synthesis.* This anabolic bulking block is now Optimal Timing Technology - OT2™ - enhanced to provide a sustained release of Leucine for six hours.

OT2™ is GNC’s intelligent nutrient delivery system engineered to help release key ingredients during crucial times when you need them most! These breakthrough products are designed to deliver immediate and sustained release of ingredients to help maintain benefits throughout your workout, day or night. OT2™ ingredients are coated with a special technology that controls when they are released.

These special actives may be seen in the product- now that’s a real technology you can see and feel! It goes without stating that protein is critical for stimulating muscle synthesis and preserving muscle glycogen stores. Leucine, a key branched chain amino acid, is one of the primary nutrients in protein responsible for these benefits. With the introduction of the unique, sustained-release technology, now muscle fueling leucine is released for up to six hours!

The full muscle building potential of a GNC product is based on its total nitrogen content- so the more nitrogen a product has, the stronger it will perform. Nitrogen needs increase during training, and if nitrogen levels are low, your body pulls from muscle stores which can result in catabolism, poor performance and longer recovery. To fuel performance and anabolism, Pro Performance® XR Series™ BCAA Advance XR™ is loaded with 5 grams of nitrogen-boosting ingredients.

Notice: Significant product settling may occur.

My favorite BCAA
I have been using this BCAA for over 6 month now and I really like it. I mix it with propel water and it taste great. I drink it during the day and during work outs and it gives me a great boost during HITT sessions. The only thing I don't like is that it doesn't mix well.

Not Satisfied
I just finished a full container of the grape flavor. The taste is ok but not good. The biggest problem I have with this product is that it just does not mix at all. BCAA's in general don't mix well but this product will leave hundreds of grains unmixed and floating in the mix bottle. The film this leaves on top of the drink is not appealing. I won't buy this product again.

I like it
I saw some good gains when using this along with L-Arginine and L-Orinithine during workouts. It helped get me over my plateau.

I know this may sound gross... but mix this berry flavor with your chocolate protein shake. It tastes like chocolate covered cherries!!!

Will not continue using
Doesn't mix well- with anything. I will go back to using the GNC Pro Performance BCAA 5000- Fruit Punch- it tastes better and mixes much better.

tastes as bad as it mixes
I used this when i was having issues recovering. It was of course recommended by the individual at GNC. Every time I took it, instant gag reflex. would not recommend.

I like it
First time using this product and on the first day I had more energy to carry through the work out and a boost in strength performance.

Doesn't mix.
The flavor isn't bad. But as someone else mentioned, the weird film that forms on top when adding water is unappealing. Almost comical, actually. It reminds me of a strange witch's brew. What's really unfortunate is how terribly bad this stuff mixes. It clings to the inside walls of my blender bottle like there's a static attraction. No matter what, I've ever tried refilling with water and shaking again (twice), it all doesn't mix in. I will definitely not be buying this stuff again.

Not Bad
I'm half way through one of the grape flavors. The taste is okay. The only problem I have with this product is that it doesn't mix well. BCAA's in general don't mix well but this product leaves a lot of grains unmixed especially if you mix it with creatine of the same brand. I will try another brand next time.
