RAD-140 Mechanism of Action

Testolone exhibits a remarkable affinity for the androgen receptor, with a Ki value of 7 nM, which is even higher than DHT. For contextualization, the affinity for the AR for testosterone in a preclinical model was found to be 29 nM and 10 nM for DHT. Unlike testosterone and many other androgen receptor-mediated anabolic agents, RAD-140 is orally bioavailable, thus negating the need for injections to achieve proper absorption.

Observed Benefits of RAD-140 in Clinical Research

Introduced in 2010 primarily for osteoporosis treatment, Testolone’s research on rats and primates implies potential supplementary benefits. Some observed effects of the RAD-140 SARM include:

• Augmented weight loss
• Enhanced lean muscle protein synthesis
• Increased clearance of beta-amyloid plaques from the brain
• Protective attributes against breast and prostate cancer
• Improved endurance

However, it must be acknowledged that the Food and Drug Administration (FDA) has neither validated nor approved RAD-140’s health effects for human use, designating it solely for laboratory research.

Studies Involving RAD-140

Some anecdotal evidence has suggested the possibility of testosterone suppression in males due to RAD-140 administration. Various animal studies have been conducted, including:

• A primate study proposed that RAD-140 might foster modest enhancements in lean muscle mass.
• Research on rats that identified neuroprotective effects of RAD-140, demonstrating its ability to activate ARs in the brain, safeguard hippocampal neurons against cell death, and expedite the removal of beta-amyloid plaques. Another study involving rats discerned that RAD-140 could potentially offer neuroprotective benefits that might avert Alzheimer’s disease and similar conditions, and may present a safer alternative to standard testosterone therapy. The group treated with 3 mg/kg RAD-140 achieved muscle tissue growth comparable to the group treated with 1 mg/kg testosterone. Still, it exhibited only half the androgenic activity in the prostate.
• In the context of breast cancer treatment, where androgens have been widely explored, the side effects of anabolic steroids have prompted the consideration of SARMs like RAD-140. A preclinical investigation found that RAD-140 notably inhibited the growth and proliferation of cancer cells in both in vivo and in vitro models of AR/ER+ breast cancer.
