Aromatizes like crazy man.
But,
“Trestolone is currently the most potent mass-building injectable steroid on the market. Its anabolic:androgenic ratio of 2300:650 is higher than any other non-17aa compound currently available. Chemically, trestolone is nandrolone with a 7a-methyl group. This small modification makes trestolone almost untouchable by binding proteins like SHBG, which is the main reason why it is so effective in such a small dose. The 7a-methyl group also increases the relative androgenic potency, eliminating the libido problems that nandrolone users often run into. Additionally, the increased androgenic profile also contributes towards greater strength gains and a drier, harder look (assuming estrogen is under control.) Interestingly, trestolone will maintain full male sexual function in the complete absence of testosterone, making a test base optional. Users can expect rapid mass gains, moderate strength gains, and a very elevated mood and libido. Side effects are minimal, with aromatization being the main cause of side effects experienced. Trestolone aromatizes into 7a-methyl estradiol, which requires meticulous AI dosing to keep under control. Trestolone acetate standard dosing starts at 20mg/day, with advanced users topping out at 50mg/day. Trestolone decanoate standard dosing starts at 160mg/wk, with advanced users topping out at 400mg/wk. Dosing past these upper limits generally makes the aromatization too difficult to control.”
