Parabolan by Bill Roberts - Parabolan is trenbolone
cyclohexylmethylcarbonate. The half-life of a steroid ester is
mostly dependent on its ratio of fat solubility to water
solubility: the longer chain the ester, the higher this ratio, and
the longer the half-life. This particular carbonate could be most
closely compared with an enanthate ester; the half-life is probably
a little less than week.
An amp (76 mg trenbolone cyclohexylmethylcarbonate) 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
(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 acetate has a "special role" in burning
fat. Rather, it is an extraordinarily potent AAS, being about three
times as effective per milligram as testosterone esters. For this
reason, any property which anabolic steroids have, trenbolone
acetate 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 Parabolan, not trenbolone
acetate) is not clear.
It is also not clear that trenbolone results in any greater degree
of increased aggression for a given amount of anabolic effect than
testosterone itself does. However, on a per milligram basis, it
undoubtedly does. The substance does not cause uncontrollable "roid
rage" despite the hype to that effect often seen.
