Increses nitric oxide production. Great for muscles. Only downside is it makes me irritable, and a little restless when you take the reccomended dosage. Steve NC

i like this type of arginine because it has no taste. the last bottle of standard l arginine from another manufacturer was hard to get down even mixed in juice. this powder gives a subtle little boost that goes great when working out

This really does help extend workout time, before exhaustion sets in. Just be careful if you have the Herpes virus in your system - you'll need to add extra Lysine.

A surprising pre-workout supplement, which I now take regularly three times per week. The first time I took it, I noticed immediately, a strong surge of mental clarity and energy. I simply added it to my pre-workout shake. Mixes in easily. Virtually no distinctive flavor or, not that I noticed any. There's definitely much better blood circulation after taking this supplement each time I work out. In the gym, this has given me an advantage because I can now work out hard during my 45 minutes to 1 hour weight lifting. Whereas before consuming this supplement, I noticed, I would need to rest more between sets, now, I am focused and can go full-intensity for my entire workout. I am in no way exaggerating the benefits. It works quite well. In fact, I ordered, shortly receiving my first order, two more cans because this supplement makes my stamina in the gym higher. My wife now also takes it because she says it gives her energy throughout her professional day. Don't know why other pre-workout supplements do not include this ingredient.

I've been using A-AKG associated with creatine and it's been amazing how I could increase weight while working out. As for aerobic exercises it works great as well.
