Abstract

BACKGROUND:
The use of anabolic androgenic steroids (AAS) is common among visitors of fitness centers. Knowledge about health risks of AAS use is limited due to lack of clinical studies.

METHODS:
One hundred men, at least 18 years old, intending to start a cycle of AAS were recruited. Baseline demographical data and reasons for AAS use were recorded. Subjects provided samples of AAS for analysis with UPLC-QTOF-MS/MS.

RESULTS:
One hundred and eleven men were seen for a baseline visit. Nineteen percent had competed in bodybuilding competitions. Recent illicit drug use was reported by 56%. Seventy-seven percent of participants had used AAS in the past and 97% of them had experienced side effects. After exclusion, 100 men comprised the cohort for follow-up. The AAS cycle performed had a median duration of 13 weeks (range 2-52) and the average dose of AAS equivalents was 901 mg per week (range 250-3.382). Subjects used other performance and image enhancing drugs (PIEDs) such as growth hormone (21%). In total 272 AAS samples were analyzed and 47% contained the AAS indicated on the label. The principal reason for AAS use was gain of muscle mass (44%). Forty-eight percent self-reported to being addicted to AAS.

CONCLUSION:
The HAARLEM-study cohort shows that strength athletes use AAS in a wide variety of cycles and often also use illicit drugs and other potentially harmful PIEDs. The quality of the AAS used is strikingly low. Follow-up of the cohort will provide novel data regarding health risks of AAS use.
