How it works
RAD-140 selectively binds to androgen receptors in muscle and bone tissue, mimicking the effects of testosterone with reduced impact on other tissues. This targeted action is researched for its potential to promote muscle growth and improve bone 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.

About Testolone (RAD-140)
Testolone (RAD-140) is a peptide supplement used to support joint and musculoskeletal health. SARM researched for muscle and bone (research-only). It is available in capsule form and dosed for adults in India and internationally. As a peptide-tradition entry in the SacredBod catalog, it is positioned as a single-ingredient option that can be used on its own or layered into a broader protocol. Testolone (RAD-140) works through the mechanisms characteristic of its class — see the mechanism and research sections for detail. It primarily acts on the joints, muscles, bones, and effects are dose-dependent, typically becoming measurable within 4-12 weeks for joint comfort. Consistency matters more than dose size for this category.
Evidence
Testolone (RAD-140) carries an evidence grade of C in the SacredBod catalog, reflecting emerging human evidence for joint and musculoskeletal health. SARM researched for muscle and bone (research-only). Benefits are cumulative rather than immediate, typically becoming noticeable within 4-12 weeks for joint comfort, and individual response varies.
Dosing
A typical dose is 10 mg, taken with food, usually in the morning. Start at the lower end, assess tolerance, and stay consistent; more is not automatically better.
Cautions
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.
