Also known as

Oxandrin

Oxandrin is a recognised alias for Clomiphene Citrate, an anti-estrogen compound. PoseidonRX stocks two items under this name: the №4 Gain Mass Course from Magnus and standalone Oxymetholone 50mg. Both are listed in the shop’s catalogues, with the course positioned for mass-gain protocols and the single item for direct use. Buyers should note that these products differ in form and intended context, not in the core anti-estrogen component they contain.
