Do You Buy Performance-Enhancing Drugs Online? Beware
Online products that claim to contain popular performance-enhancing drugs called selective androgen receptor modulators (SARMs) often don’t, according to researchers at Brigham and Women's Hospital in Boston and investigators from the United States Anti-Doping Agency and the Uniformed Services University of the Health Sciences.
SARMs, which are not approved by the FDA, are sometimes used by bodybuilders, athletes, soldiers, and others to build muscle and reduce muscle loss. Researchers analyzed 44 products available for purchase online that listed common SARMs (ostarine, andarine, RA140, ibutamoren, GW501516, and SR9009) as ingredients. An online search for products containing SARMs produced more than 210 results, but many of these products were discontinued, out of stock, or restricted.
Only 23 of 44 products tested by the researchers actually contained these substances. The amount of active compound in the product matched the amount listed on the label in just 18 of the products. Eight didn’t contain the compound listed on the label, and four contained no active compounds at all.
