D-phenylalanine (enkephalinase inhibitor)
Interesting substance, its one of the few dextro (right-spinning optical isomer) amino acids that you can process or something.
I think its fascinating because its purportedly an endorphin reuptake enkephalinase inhibitor? or something so its potentially quasi-opioidergic. I’m not sold on the notion its legit but its definitely a provocative idea.
I beg your finest pardon. That’s my secret recipe to success.
+1 for L-theanine though, it’s one of my favorite supplements. Although, more than once I’ve had to explain to someone that it’s not a Spanish word (“el theanine”).
