I've used both Parabolan and Finaject, both pharm grade great products from the past. Parabolan, the long chain ester trenbolone cyclohexylmethylcarbonate was similar in half-life to enanthate. Finaject was the acetate version and was the more potent of the two, although parabolan had a huge fan club also.
An amp of parabolan(76 mg trenbolone cyclohexylmethylcarbonate) was comparable only to 58 mg of trenbolone acetate. (The acetate is a little more potent, more effective per milligram, because the acetate ester is lighter and therefore a higher percentage of the weight is trenbolone.) This is why the molecular weight of the ester matters.
Nowdays I just make the regular homebrew tren acetate like most. Still damn fine. I have been meaning to make up some of the enanthate from powder.
