works great.  Better than regular l-arginine.
I've been taking regular L-Arginine for a few years to improve blood flow, but what a difference with this product!  A half hour after taking it, I feel a little bit of a muscle pump, almost as though I'd gone to the gym.  Since I'm not able to workout right now, it's great to feel that.  Not to mention the fact that the pump lets me know that it's helping with blood flow.  It tastes absolutely horrible, so I put it in size 000 gelcaps, which hold about 1gm each.
