I have also heard that Ttokkyo was coming out with a parabolan copy. Not trenbolone acetate, but trenbolone cyclohexylmethylcarbonate. This is a rumor that I don't remember where I read, probably a message board so the credibility is questionable. The rumor was that GAC cannot produce more of their parabolan copy because Ttokkyo bought out all of the raw material for parabolan.
