The Council for Responsible Nutrition, a supplement industry trade group, launched a campaign on social media, #SARMSCanHarm, and is working with sports clubs, fitness groups and coaches around the country. They’re not supported by expert guidelines and they’re dangerous. “I always tell them the same thing,” he said. But he counsels them to give up the drugs they are using because they are jeopardizing their health. O’Connor said he relates to a lot of his patients and understands their desire to be bigger, stronger and fitter. Some also experience diminished sex drive, hair loss, acne and irritability, though it’s often difficult to know whether it’s the SARMs causing these symptoms or some other unlisted ingredients in the products.Īs a longtime power lifter, Dr. But one thing he often sees among people using SARMs is that their cholesterol profiles worsen and their liver enzymes rise, a sign of increased strain on their livers. It’s hard to determine the precise impact of SARMs because many people who use them combine them with other drugs, supplements and substances, Dr. He said that since 2010 has seen “hundreds, maybe over 1,000 men on SARMs” from all walks of life: police officers, defense workers, amateur athletes, accountants and others. Thomas O’Connor, a doctor who founded a men’s health clinic and wrote a book called “ America on Steroids,” said that many of his patients are anabolic steroid users who turned to SARMs because they were told that they were safe and nontoxic. “Long-term studies are needed to clarify the effects of long-term SARM administration on cardiovascular risk,” the authors concluded. But it had other effects as well, for instance causing a drop in HDL cholesterol, the protective kind, which raised questions about its effects on heart health.

A number of trials are looking at their usefulness in cancer patients, people recovering from hip surgery, and postmenopausal women with urinary incontinence linked to weak pelvic muscles.Ī three-week trial at Boston University demonstrated that LGD-4033, a SARM developed by Ligand Pharmaceuticals, was safe and tolerable in healthy men, producing “significant gains in muscle mass and strength” without raising levels of a protein linked to prostate cancer. SARMs were designed to selectively target skeletal muscle and spare other tissues, in an attempt to reduce some of these unwanted side effects. But they act on many tissues throughout the body and have been tied to a litany of potential side effects, including prostate problems and cardiovascular events. Many chronic diseases, such as cancer, heart failure and kidney disease, are also punctuated by a loss of muscle and physical mobility.Īnabolic and androgenic steroids such as testosterone can help people regain muscle and physical function. Scientists developed SARMs decades ago to counter the age-related decline in muscle and strength that tends to begin around middle age and that can contribute to falls and broken bones. While the underground use of SARMs has made them controversial, the drugs could one day serve a crucial purpose for many patients.
And in October, a top CrossFit Games competitor, Ricky Garard, was stripped of his third-place title after testing positive for two SARMs: ostarine and testolone. The college basketball star Allonzo Trier of the Arizona Wildcats was also suspended for using SARMs. Last year, Joakim Noah, a center for the New York Knicks, was suspended for 20 games for testing positive for a SARM.
