Why source RAD-140 from Sports Technology Labs
Quality control across the research-compound industry is inconsistent, which makes third-party verification essential. A 2017 analysis published in JAMA examined 44 products marketed online as SARMs and reported wide gaps between labels and contents.

What is RAD-140?
RAD-140 (Testolone) is a non-steroidal selective androgen receptor modulator (SARM) that functions through high-affinity binding to the androgen receptor (AR). Once bound, it acts as a selective agonist, inducing a conformational change in the receptor that influences downstream gene transcription. This AR–ligand complex translocates to the cell nucleus, where it interacts with androgen response elements (AREs) to regulate expression of genes involved in androgen receptor signaling pathways.
Mechanistically, RAD-140 exhibits tissue-selective receptor activation by differentially modulating androgen receptor signaling in various tissues. This selectivity is driven by receptor conformation and co-regulator recruitment, which alters transcriptional activity depending on the cellular environment. The compound’s activity is therefore defined by its interaction with the androgen receptor and the subsequent modulation of AR-dependent gene expression.
Important regulatory information
RAD-140 is an investigational compound. It is not approved by the FDA and is not a dietary supplement, drug, or food. Marketing it for human ingestion is unlawful.
Listed by the World Anti-Doping Agency under S1.2 (Other Anabolic Agents), the class that includes selective androgen receptor modulators, banned both in- and out-of-competition (ref. 8).
In the United States, RAD-140 is not currently a federally scheduled controlled substance and may be legally purchased and possessed for laboratory research use. State and institutional rules may apply.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
