Also known as
Andarine
PoseidonRX lists two distinct compounds under the Andarine heading: YK-11 and s-4. The s-4 entry is a selective androgen receptor modulator, while YK-11 belongs to the myostatin inhibitor class. Neither product functions as an estrogenic or progestogenic agent. These items are sold for research and educational purposes only. Athletes and performance researchers should verify their specific protocol needs before selecting between these two separate categories of compounds.
Compound Identity
This page groups s-4 and YK-11, which are chemically distinct molecules. S-4 acts as a selective androgen receptor modulator, whereas YK-11 is classified as a myostatin inhibitor. The two compounds do not share the same primary mechanism of action or tissue selectivity profile. Users should ensure they understand which specific agent they are purchasing before initiating any cycle.
Product Selection
PoseidonRX offers 60-tablet packs containing 10 mg of YK-11 and 25 mg of s-4. The dosing parameters differ between these two items. Buyers must carefully check the label to confirm they have selected the correct compound for their intended use. Both products are available from Magnus, and the shop ships across the European Union.
