A measured look at mesterolone, a weakly anabolic oral DHT derivative used as an adjunct to lower SHBG and support libido, and what is worth tracking.
At a glance
Proviron is a brand name for mesterolone, an orally active derivative of dihydrotestosterone (DHT). Unlike most oral steroids it is not 17-alpha-alkylated in the usual liver-stressing way, and it is not very anabolic. People use it mainly as an adjunct - to lower sex hormone binding globulin (SHBG), as a mild anti-estrogenic support, and for libido - rather than as a mass builder.
This is an educational tracking guide, not medical advice and not a recommendation. Mesterolone is a prescription medicine in many countries and is discussed here for educational tracking only.
Mesterolone is gentler on the liver than most orals but is still an androgen: it is suppressive, can worsen lipids, and is not a benign supplement. It is prescription-only in many places. Anyone using it should confirm SHBG, testosterone, estradiol, and lipids with bloodwork rather than guessing at its effects.
