Mesterolone
Also known as: Proviron
Status
Approved elsewhere. Not approved in the United States. Approved in several other countries for androgen deficiency. Schedule III controlled substance in the US.
What it is
A weak oral androgen used in some countries for hypogonadism, not liver-alkylated.
What published research measured
A 1-methylated dihydrotestosterone derivative. It is not 17-alpha-alkylated, so it lacks the hepatic burden of the oral androgens above, and it is a weak anabolic — the reason it appears in reports is its affinity for sex hormone binding globulin and mild anti-estrogenic behavior rather than any tissue-building effect. It still suppresses the body's own testosterone production.
