OK - Parabolan has the same active ingredient that Finaplex-H does (Trenbalone). The difference between the two is the esters. Parabolan had an ester that allowed people to take it 2 times a week or so, where the Fina that people take now needs to be taken at LEAST every other day if not EVERY day. Parabolan is no stronger or weaker than fina - its just considered "better" because you don't have to inject as often with it. The most important thing tho - PARABOLAN IS NO LONGER AVAILABLE. Anyone trying to sell it is 99.9% guaranteed to be scamming you.
