An amateur body builder who used steroids to improve his physique died when his heart grew to twice its normal size, an inquest has heard.
The coroner warned against the use of steroids
Stephen Fraser, 33, from North Yorkshire, died of multiple organ failure in October 2002.
His girlfriend Sarah Hawsley told an inquest in Harrogate that he had used steroids to help him win a body building competition in May 2000.
He had used them in the build up to other competitions on and off ever since, she added.
Dr Carl Gray, a pathologist at Harrogate District Hospital, told the inquest that anabolic steroids increase muscle bulk but also lead to other side effects.
Mr Fraser's heart had doubled in size, but his arteries had narrowed considerably - some to the size of a pin head.
He added that, on the balance of probabilities, the steroids contributed to the heart disease and subsequent death.
Returning a verdict of death by misadventure, acting coroner Geoff Fell quoted the director of the National Sport Centre.
He said: "The temptation to take anabolic steroids should be offset by the risk of an early grave."
