Right now I'm really liking absolutely abliderated, anabeta elite(50mg f95), e9, and thyrocaps. I'm stacking with alphamine, but your lipodrene would work too. All that's not necessary since you're running osta, but replacing the ABE with your osta and adding f95 would make for a great stack! I'm a little young to mess with that stuff yet so that's the only reason I haven't. Also, tta 500 would be solid but then were just taking obscene amounts of pills. Lol
Either way, all of these products have served me incredibly well
