Trenbolone is a highly androgenic steroid, with binding to the Androgen Receptor (AR) in the region of three times as high as testosterone. It does not aromatise and so is not subject to estrogenic side effects. In addition to high androgenicity, it is also extremely anabolic too, thus is very good at building muscle mass, and retaining muscle mass in a calorie deficient mode.
