I am just answering based on your initial question here, but I believe
@sns8778 could shed some more light on OTC fat burners. It sounds like lean edge, paradoxine, mitoburn, and recomp20 might be right up your alley if you are looking for OTC fat burning stuff without completely screwing up your dopamine receptors and hormonal shiit...idk
If I didnt need adderrall for ADD / ADHD I wouldn't touch the stuff for any type of off label use
