Bro,
TREN aka trenbolone is NOT a test booster Bro...its a strong 19 nor steroid used to increase lean mass in beef cattle.
Here is a quick explaination Bro.
Trenbolone compounds have a binding affinity for the androgen receptor five times as high as that of
testosterone.[SUP]
[6][/SUP] Once
metabolized, the drugs have the effect of increasing
nitrogen uptake by muscles, leading to an increase in the rate of
protein synthesis. It may also have the secondary effects of stimulating appetite and decreasing the rate of
catabolism, as all
anabolic steroids are believed to; however, it should be noted that catabolism likely increases significantly once the steroid is no longer taken.[SUP]
[7][/SUP] Trenbolone has proven popular with anabolic steroid users as some believe it is not metabolized by
aromatase or
5α-reductase into
estrogenic compounds such as
estradiol, or into
DHT; however, studies on this are mixed with some studies showing a potential increase in both.[SUP]
[8][/SUP][SUP]
[9][/SUP] At least one study in rats has shown that Trenbolone causes gene expression with the
androgen receptor at least as potent as DHT. This evidence tends to indicate Trenbolone can cause an increase in male
secondary sex characteristics without the need to convert to DHT.[SUP]

Since steroids generally cause
virilization effects in women in even small doses, this drug should not be taken by women. Kidney toxicity has been suggested, but has not yet been proven, and scientific evidence supporting the idea is absent from the bodybuilding community that perpetuates this idea. The origin of this myth most likely has to do with the rust colored oxidized metabolites of trenbolone which are excreted in urine and often mistaken for blood.[SUP]
[11][/SUP] Trenbolone and 17epi-trenbolone are both excreted in urine as conjugates that can be hydrolyzed with beta-glucuronidase.[SUP]
[12][/SUP] This implies that trenbolone leaves the body as beta-
glucuronides or
sulfates
