why would you use only 1 when everything is affordable and everything is available? it's not like any of us are so poor we can only use 1 bbing drug.
that's like asking a multi-millionaire (or billionaire.. whatever.. somebody who can buy anything/everything) what 1 car they'd drive if they could only choose one. why would they? when they can afford one for each day of the week? how 'bout some metaphors.. test= AMG S65, tren= Lambo Murcielago, deca= Porsche 911 turbo, npp= Porsche GT3, dbol= H1 Hummer, methyltrienolone = Pagani Zonda F, masteron= Aston Vanquish, primobolan= mazda Miata, anavar= volkswagon beetle, ect...
asking which 1 bbing drug is like asking what one kind of cereal you'd eat.
