TrenMix 150

No. ClinicalTrials.gov lists not a single trial with trenbolone (as of 26 October 2026), ChEMBL records no approval for trenbolone acetate. Trenbolone is used in cattle fattening, according to one paper in over 20 million cattle a year. Everything here is the state of research, not a recommendation.

Short esters like acetate are released quickly, long ones keep the level up for longer. In the end the same trenbolone always acts. There is no study of its own on blends of trenbolone esters, not even in animals.

In the lab trenbolone bound the human androgen receptor about as strongly as DHT and the (bovine) progesterone receptor slightly more strongly than progesterone. A review cites about three times the binding of testosterone. Unlike testosterone it is not converted into stronger androgens. In cell experiments it also blocked the effect of glucocorticoids.

In castrated rats the muscle fibre cross-section grew by 94 percent under trenbolone enanthate, satellite cells by 178 percent. Bone density was preserved after castration, the femoral neck was 28 percent stronger. Low levels kept the prostate at the sham level, the highest level enlarged it by 68 percent. In non-castrated rats fat mass fell by 37 percent in 6 weeks.

In the Global Drug Survey 2024, 237 men using trenbolone reported almost all queried concerns more often than 909 men using other anabolic steroids, for example concern about the heart (54.4 vs 31.2 percent), restlessness and irritability (29.1 vs 12.9 percent) as well as anger and aggression (21.1 vs 9.2 percent). In a second survey of 282 men a higher amount of trenbolone was linked to more verbal aggression.

For anabolic steroids in general, reviews describe falling HDL cholesterol, rising blood pressure, more aggression and a suppressed hormone axis that often takes months to recover after stopping. In rats on trenbolone the body's own sex hormones were suppressed and the prostate grew benignly. In the lab trenbolone also binds to the progesterone receptor, the lexicon covers this under prolactin.

For anabolic steroids in general: in one study current users had higher 24-hour blood pressure, 51 percent had systolic hypertension vs 17 percent without anabolic steroids. In long-term users the heart's pumping function averaged 52 instead of 63 percent, along with more plaque in the coronary arteries. In the HAARLEM study every one of the 100 men had at least one side effect.
