Description
Proviron (Mesterolone) 25mg
50 tablets, 25mg mesterolone per tablet
Mesterolone is an orally active dihydrotestosterone derivative. Unlike most oral compounds in this category it is not 17-alpha alkylated — it achieves oral activity through 1-methylation instead, which is a meaningful structural distinction between this listing and the rest of the orals range.
- 25mg mesterolone per tablet
- 50 tablets per box — 1250mg total
- NOT 17-alpha alkylated
- Dihydrotestosterone derivative; non-aromatising
- Documented high binding affinity for SHBG
Because it lacks the 17-alpha methyl group, mesterolone sits apart from the other orals here in structural class despite being taken by the same route. Store the box sealed and dry at room temperature.
