KLOW: Total game-changer for my skin. Years of slamming energy drinks completely wrecked my gut, which was showing up on my face and random bug bites from camping not healing as fast. For me, KLOW was the missing puzzle piece(needless to say, the energy drinks are gone for good).
RETA: Sort of shocked me by melting off a stubborn 20 lbs way faster than anticipated over this past spring/summer.
Semax (Currently Taking once a day): Picked this up to help with learning a new language. I honestly didn't expect a massive jump, but Anki deck output skyrocketed from just 10 vocab cards a week to comfortably pushing 40. Not bad with all the other things I've got going on.
