Parabolan (Trenbolone Cyclohexylmethylcarbonate)

We 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.

Trenbolone is a steroid having the advantages of undergoing no adverse metabolism, not being affected by aromatase or 5alpha-reductase; of being very potent Class I steroid binding well to the androgen receptor; and having a short half life, probably no more than a day or two. Fifty milligrams per day is a good dosing for someone on his first cycle or someone who is as yet less than, say, 20 pounds over his natural limit; while 100 mg/day may be preferred by the more advanced user who has already gained more than this. These doses are assuming that Trenbolone is the only Class I steroid being use. There really is no need to stack another -- testosterone being the only sensible exception -- but if another is stacked then the amount of Trenbolone may be reduced accordingly.
