What is in SX3
SX3 brings three research compounds together in one product:
- MK-2866 (Ostarine), 30mg
- S4 (Andarine), 50mg
- SR9009 (Stenabolic), 30mg
MK-2866 and S4 are non-steroidal selective androgen receptor modulators (SARMs) studied for their tissue-selective binding to the androgen receptor. SR9009 is not a SARM. It is a synthetic ligand of the Rev-Erb nuclear receptors, which researchers study in connection with circadian rhythm and metabolic gene expression.
Like everything we sell, this product is manufactured in the US and third-party tested.
