Ten tablets in a blister at 25 mg each — the smallest mesterolone pack in this group, and the one that most resembles something taken off a pharmacy shelf.
Provironum carries the Shering name, the label historically tied to the original brand of this molecule. Mesterolone itself is an orally active androgen built on the dihydrotestosterone skeleton, with strong affinity for sex hormone binding globulin and very little anabolic effect of its own. Ten tablets is a sample-size box rather than a working quantity, which is worth registering before it goes in the cart.
