I seriously doubt the "underground" Parabolan (TH) is actually Parabolan.
People who were using "GGA$$'s" TH like they would real Para (1-2 injections per week) weren't gaining shit.. But when they started using their supposed para like regular ol' trenbolone acetate/fina (ie EOD injections), that's when they started seeing gains. I thought the thing that made Para so superior to Tren Acetate was the fact that you didn't need to shoot it as often (because of its longer half-life)?? So either "GA$'s" TH was just relabled TA, or there is really no difference between the two esters.
