L-Tryptophan capsules
by William Duong

Tryptophan is important is protein production, and therefore is important to me. I also take protein supplements, and try to eat a protein-based meal, so Tryptophan is key for me to increase my efficiency. I think most people who work out don't know about this. I think most serious lifters should use tryptophan, because it is so key in a high-protein diet.

I'm a total geek I research everything! Especially after I heard someone mention that "turkey" has tryptophan" in it and that is why everyone is so calm after turkey dinner. I am not so big on eating turkey every time I want to calm down. So I found it, in this supplement.
