What it is
›
RAD-140 (Testolone) is a SARM researched for strong androgen-receptor signaling. It is an investigational research compound, not an approved medicine, sold for research only.
• Status: investigational, sold for research only
• Researched for lean mass and strength signaling
• Oral, so there is no injection
How it works
›
A SARM with a strong pull on the androgen receptor.
• Binds androgen receptors in muscle and bone
• Studied for androgen-like signaling with some selectivity
• Can meaningfully suppress natural hormones
