QUICK ANSWER · AEO / GEO
Andarine, S4 and GTx-007 identify an experimental nonsteroidal SARM in the reviewed sources. Evidence is dominated by rat muscle, bone and reproductive-tissue models; these signals do not establish human treatment, performance benefit or long-term safety. FDA records identify marketed andarine products as unapproved drugs and document a product recall involving andarine and ostarine. WADA 2026 prohibits andarine at all times.

Frequently asked questions
What is Andarine / S4?
Andarine / S4 is described pharmacologically as Experimental nonsteroidal selective androgen receptor modulator. Andarine, S4 and GTx-007 identify an experimental nonsteroidal SARM in the reviewed sources. Evidence is dominated by rat muscle, bone and reproductive-tissue models; these signals do not establish human treatment, performance benefit or long-term safety. FDA records identify marketed andarine products as unapproved drugs and document a product recall involving andarine and ostarine. WADA 2026 prohibits andarine at all times.
Does Andarine / S4 have strong evidence?
PrimeCoreBio records Evidence Grade E. This grade describes evidence strength, not comparative effectiveness or suitability for an individual.
Is Andarine / S4 approved everywhere?
No global conclusion should be inferred. PrimeCore Class C must be read with the exact product, country and indication on the source-rich profile.
