RAD-140
RAD-140 Product Description — Research Use Only
RAD-140, also known as Testolone, is a research compound studied as a selective androgen receptor modulator, commonly known as a SARM. It is not a peptide, but it is often grouped within peptide and research-compound catalogs because of its use in androgen-receptor, anabolic-pathway, lean-mass, bone-support, and body-composition research.
Research on RAD-140 has most commonly focused on androgen receptor activity, muscle-support pathways, lean-mass markers, bone-density research, tissue-selective anabolic signaling, and hormone-response markers. Published research describes RAD-140 as a nonsteroidal SARM designed to activate androgen receptor pathways with tissue-selective activity in muscle and bone research models.
RAD-140 is commonly studied for:
Androgen receptor activity — how the compound interacts with androgen receptor pathways
Muscle-support pathways — signals connected to muscle growth, repair, and protein balance
Lean-mass research — markers related to lean tissue and body-composition changes
Bone-support pathways — research involving bone strength, density, and maintenance
Tissue selectivity — how activity may differ between muscle, bone, and other tissues
Anabolic signaling — pathways connected to tissue growth, repair, and recovery response
Hormone-response markers — how androgen-related pathways influence biological signaling
RAD-140 is commonly studied because SARMs are designed to activate androgen receptor pathways in a more tissue-selective way than traditional steroidal androgens. RAD-140 research has evaluated muscle-mass, bone-mineral-density, androgen receptor signaling, and tissue-selective activity, while additional studies have explored RAD-140 in androgen/estrogen receptor-positive breast-cancer research models because of its androgen receptor activity.
