I have recently been given a couple tubs of freeform L-Arginine powder and L-Glycine powder.
I've read some stuff about both (I remember CT writing some things about it some time back) and it seems that taken in the correct doses and times that it can't hurt, but I'm not quite sure I understand what real benefits I might expect.
My understanding is that glycine proportedly may help or aid recovery, so post/peri-work out. I will experiment accordingly.
The arginine I'm more skeptical about. What I can say is that the L-Arginine, on it's own or in a non-sweetened drink tastes absolutely awful. lol.
Has anyone taken one or both of these supps in free form? Derive any benefit?
