Dr. Thomas O'Connor, MD, PA

Dr. Thomas O'Connor is the first American board-certified internist to focus his medical practice specifically on the health and recovery of individuals who use anabolic steroids and androgens.

He founded Testosteronology®, a dedicated subspecialty of internal medicine that addresses steroid-induced hypogonadism and associated cardiovascular and metabolic concerns.

Dr. O'Connor has over 20 years of experience treating men and women with a history of anabolic steroid, SARM, and PED use. He has been a board-certified MD since 2005 and provides guidance on harm reduction methodologies.

Dr. O'Connor is a clinical instructor at the University of Connecticut School of Medicine and has been featured in various media publications, including Generation Iron, Dr. Phil, National Geographic, The New York Times, Muscle and Fitness, and others.

Dr. O'Connor also co-authored the largest survey on anabolic steroid use, which involved 2,385 men and was published in the peer-reviewed American Journal of Men’s Health. He holds active medical licenses in Connecticut and Florida.

Highlights Selective androgen receptor modulators (SARMs) are a novel class of synthetic compounds that can build moderate amounts of muscle in humans. In clinical settings, anabolic steroids appear to be more effective at increasing lean mass than SARMs. Some SARM users have reported exceptional improvements in muscular strength. People exposed to SARMs may experience liver […]

Highlights SwissChems supplies SARMs and peptides in capsule form, benefiting researchers who may prefer an alternative to liquid SARMs. SwissChems can enhance its services by providing discounts for cryptocurrency payments. SwissChems is not a suitable source for preclinical research, as it only manufactures SARM capsules. Researchers can save 10% on their SwissChems order by using […]

Cardarine, otherwise known as GW501516, is a peroxisome proliferator-activated receptor delta (PPARδ) agonist that can significantly increase fat loss (lipolysis) and muscular endurance (Chen et al., 2015). Cardarine is a unique compound because it improves athletic performance without the cardiotoxic side effects commonly associated with endurance-boosting drugs. For educational purposes, we have republished several before-and-after […]

Highlights Sports Technology Labs is one of the highest-quality SARM companies on the market, formulating compounds at over 98% purity. Sports Technology Labs’ products appear to be competitively priced. Sports Technology Labs may be an optimal source for researchers wanting to pay with a debit or credit card. Researchers can save 15% on their Sports […]

Highlights RAD-150 and RAD-140 can enhance body composition and improve athletic performance. Consequently, individuals competing in professional sports can fail drug tests, as both of these selective androgen receptor modulators (SARMs) are prohibited by the United States Anti-Doping Agency (USADA) and the World Anti-Doping Agency (WADA). RAD-150 appears to be more appropriate for research focused […]
