Proviron Products: Brands and Options

Proviron is the Bayer brand of mesterolone, and the 25 mg tablet is the only pharmaceutical strength it has ever been sold in. Regional versions and generics copy the same size, which is why every dosing scheme is built in multiples of 25 mg. Mesterolone is not FDA approved and is a Schedule III controlled substance in the US, so there is no legal pharmaceutical product on the American market; a licensed physician can prescribe compounded mesterolone off label.

Outside the US, Proviron is a prescription medicine in many countries, and that is where most legitimate tablets come from. The rest of the market is research chemical sellers and underground labs. See Proviron for sale for the three supply channels and what each costs, and Proviron 25mg for how the single tablet size is used.

Proviron is faked less often than Anavar because mesterolone is cheap to make, but the risk is underdosing rather than substitution. A tablet that costs much less than the pharmacy price for the same country, a blister that does not match Bayer's packaging for that region, or a seller that will not name the manufacturer are the warning signs. The compound does not aromatize and does not cause water retention, so a product that produces either is not mesterolone.

Dosing is simple once the product is real: one 25 mg tablet a day for a TRT add-on, two to three for on-cycle use. Proviron dosage covers the ranges, Proviron side effects covers what to expect at each, and Proviron half-life explains why the tablet is usually split across the day.
