How it works
Ostarine selectively binds to androgen receptors primarily in muscle and bone tissues, mimicking the anabolic effects of testosterone with reduced androgenic side effects. This action is intended to promote tissue repair and strength.
Who should take it
Adults looking to address joint stiffness, muscle weakness, joint pain. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
