I like Clen, and yes Trip myself and many others can take it before bed. Personally the best combo i've ever used was clen/ketotifen, i was sweating profusely, it was ridiculous. As for over the counter Recreate, Leviathan Reloaded and DCP are your best bets. Only thing i find with Clen is i don't like how some of my workouts are inhibited like leg day for example, squating on clen i'm soooo outta breathe it's unbelievable.
