Divanil (3, 4-Divanillyltetrahydrofuran)
Divanillyltetrahydrofuran is the primary ingredient in Mass FX. It is extracted from Urtica Diodica or the stinging nettle. It functions by attaching to the sex hormone-binding globulin (SHBG) and prevents it from binding to testosterone and estradiol. SHBG is responsible for regulating the amount of biologically active hormones in your body. This results in more bio-available testosterone (free testosterone) and estradiol (free estradiol). Elevated levels of free testosterone and free estradiol help promote muscle growth.
25R-Diol [(3b, 5a, 6a, 25-R)-Spirostan-3, 6-Diol
