one is injected, and the other is taken by mouth.
Love the Zambons. Ran 50mg eod while competing. Clean muscle no water retention. Burned like a bitch goin in an ampules a pain to open but my favorite by far. Havent had legitimate Zambons in hand in a while but some sponsors have em. Got big as an ox on em and lean. But I remember payin like $18 a pop which is expensive as hell lookin back circa 2001. Set many records on Zambon alone.
the injectable should be more potent ,its not pasing through the digestive system ,i have no idea how much more potent it would be though .
to the guy that said it was around the same as 75mg oral ,thats kinda the answer i was looking for
