An amp (76 mg trenbolone cyclohexylmethylcarbonate) of yellow raw powder Parabolan is 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.)
The properties of Parabolan are the same as Trenbolone Acetate Revalor (Finaject) except for longer half life. While Finaject itself is no longer available, in some cases injectable preparations from Finaplix have been made. The substance is the same: trenbolone acetate.
There is no evidence in the literature, nor I think practical evidence, that trenbolone has a “special role” in burning fat. Rather, it is an extraordinarily potent steroid, being about three times as effective per milligram as testosterone esters. For this reason, any property which anabolic steroids have, trenbolone will demonstrate more strongly per milligram.
I have found no indication in the scientific literature of particular kidney toxicity with trenbolone. I know of a number of users, at doses of typically 50 mg/day, who have experienced no problems. There are however anecdotal claims of kidney problems. It seems to me, however, that this is occurring only with athletes stacking an incredible amount of drugs, and how the blame can fairly be laid at trenbolone (actually at yellow raw powder Parabolan, not trenbolone acetate) is not clear.
