Trenaver H (Trenbolone Hexahydrobenzylcarbonate) acts similarly to testoster- one, although it has a binding affinity for the androgen receptor five times as high as that of testosterone. It does also carry a more favorable balance towards anabolism than androgenism. Once metabolized, the drug has the effect of in- creasing nitrogen uptake by muscles, leading to an increase in the rate of pro- tein synthesis. It also has the secondary effects of stimulating appetite, reduc- ing the amount of fat being deposited in the body, and decreasing the rate of catabolism. Trenaver H has proven safer with users as it is not metabolized by aromatase or 5a-reductase into estrogenic compounds such as estradiol, or in- to DHT.This means that it also does not cause any water retention normally as- sociated with highly androgenic steroidal compounds like methandrosteno- lone.Trenaver H and it's derivative 17epi-trenbolone are both excreted in urine as conjugates that can be hydrolyzed with beta-glucuronidase. This implies that trenbolone leaves the body as beta-glucuron half life of 5-7 days.
