Half-strength oxymetholone: this one is tabletted at 25 mg instead of the traditional 50 mg, with a hundred tablets to the pack. Halving the conventional unit is the whole point of the presentation, giving finer resolution on how much active substance a single tablet contains.
The substance is an oral androgen derived from DHT, alkylated at C17 and fitted with a 2-hydroxymethylene group that gives it properties unusual for its family, chiefly an oestrogenic effect produced at the receptor rather than through conversion. Pharmacom Labs is one of the few producers to offer the compound at a non-standard strength.
