sr-9011
SR-9011 is a synthetic compound marketed as a selective androgen receptor modulator (SARM), though there is limited scientific evidence supporting its classification or safety. SARMs are often sold as dietary supplements via the internet with claims of performance enhancement, but studies show many products are mislabeled, contaminated, or contain unapproved pharmaceutical ingredients that pose health risks.
Lab Notes — Research Studies
01 Chemical Composition and Labeling of Substances Marketed as Selective Androgen Receptor Modulators and Sold via the Internet
Analysis of 44 SARM products sold online found that 39% were mislabeled and many contained unapproved drugs, demonstrating significant quality control issues with internet-marketed SARMs including potential contamination and incorrect labeling.
View Study ((PubMed))02 Prohibited Contaminants in Dietary Supplements
Review found that poor manufacturing processes and intentional contamination with banned substances continue to occur in dietary supplements, with weight loss and muscle-building supplements posing greater contamination risks.
View Study ((PubMed))03 Unapproved Pharmaceutical Ingredients in Dietary Supplements Associated with FDA Warnings
Analysis of FDA's tainted supplements database revealed widespread contamination with unapproved pharmaceutical ingredients in supplements marketed for sexual enhancement, weight loss, and muscle building between 2007-2016.
