GNC Chemistry Labs L-Arginine Powder, 30 Servings

"I've been adding this Beyond Raw L-Arginine to my pre-workout stack and the pumps are incredible. It mixes easily, has no weird aftertaste, and definitely helps with muscle endurance during heavy lifts. High-quality lab grade stuff. Highly recommend!"

What I’ve been told more oxygen into your blood system Ben taking this for over a year now I guess it works

Loved this. There’s no taste to it so it mixes well other drinks. Easy to mix, no smell, and I seem to notice how much better I feel when taking it, so it seems to be effective. I’ve been using this product for about 7 years now, and I love it. Bought others to try, but I always come back to this.

Good stuff, could tell the difference, it works...

good

For older gentlemen this is a great boost for libido. Would recommend 1 scoop daily in juice and add anything else you want in fruit drink. Very good product. Stay with the best.

My energy levels during the workout increased. The thirst levels also increased. The taste is bland so it helps as well.

I miss the older GNC L arginine. This definitely has no after taste like the other lesser brands

Esta es una de las mejores fórmulas de Arginina que he probado, funciona de maravilla y la calidad es indiscutible. Sin embargo el precio es bastante alto pero así esta en todos lados, imagino que es por su calidad.
