Whats the benefits of L ornithine and Arginine and when is the best to take it? I have the gnc version of it and I got Amino 1000 from GNC as well... are these good products? And i was told about leucine...

Arginine and Ornithine work together to help your body produce growth hormone. Take them before bedtime on a relatively empty stomach. You can also take arginine before you workout to boost GH levels.
Any amino supp is prolly good, however there are better brands than GNC. I would go for Purple Wraath by Controlled Labs, or Xtend by Scivation. Both awesome products.
