PrimaForce AAKG Arginine Powder, 250 grams (L-Arginine and Alpha-Ketoglutarate Acid) Premium Workout Supplement, Non-GMO, Vegan, Gluten Free

Some serious pump here! I take three little scoops mixed into a glass of cold water on an empty stomach, and then chase it down with another glass of cold water because it is rather acidic tasting. Not terrible, but also not something I want lingering in my mouth and throat any longer than necessary to get it down to where it can be absorbed. I noticed some good side benefits, like less brain fog, and better performance in the bedroom, if you know what I mean. This stuff will pump up your blood supply for sure.

This is a good product, you will feel the N.O rush, i take 3 to 5g before my workout 💪

Your nostrils will opened up to oxygen greatness delivered straight to your muscles. Don't expect a miracle. This product is great only if you push yourself at the gym, go for failure and you will be impressed.

This, out of a dozen NO2 supplements, is the most effective for me. I actually could not keep lifting because my muscle became too engorged with blood, not due to fatigue! Keeps everything full, vascular and circulating.I posted a review awhile ago about how this product upset my stomach and made me sick. Fortunately, it was some medication prescribed that I was allergic too. This product was so effective I was willing to risk becoming very ill again in hopes that it was a bad batch.

I mix this with citrulline malate 1/2 each serving and feel my blood flowing instantly. No caffeine needed I mix it with something sweet Gatorade or whatever and chug it down fast because it’s crazy sour.

I recently switched form the GNC brand to this one. Within 2 scoops I noticed the difference. When I take this in conjunction with other supplements. I can actually feel my skin stretching across my biceps and forearms during the day. I will be buyer of this brand for eternity I finally got that feeling I had before from arginine.....

Provides excellent pump and mixes easily. Doesn't seem to cause stomach upset as some other brands have prior in my experience.

A big part of me wants to give this company the benefit of the doubt since I love a couple of their other products. However, I'm not sure this product really added anything to my physique or strength. Therefore, I'm giving it three stars simply because I can comfortably say some of their other products work. For me, the verdict is still out on how much this adds to your workouts.
