A seven-foot tall teenage bodybuilder who wanted to be the new Dwayne 'The Rock' Johnson died instantly when an artery burst in his chest after a workout.
Andrej Gajdos, 19, completed intense exercise sessions twice a day and used steroids to bulk up.
The teenager - who was 7ft 2in and 19 stone - died instantly when he collapsed outside a supermarket near his home in Weston-super-Mare in Somerset.
His use of steroids contributed to his enlarged heart - which was 50% bigger than average, an inquest into his death was told.
Four different types of steroids were found at Gajdos' home after his death, and traces of the drug along with testosterone was in his system.
The consultant who carried out the teenager's post-mortem examination told Avon Coroner's Court that he had "never met a man so big".
"Andrej's heart weighed 680g, and a normal heart is between 400 and 500g - he wasn't a normal man," Dr John Oxley said.
Dr Oxley said the 19-year-old's use of steroids would have enlarged his heart - increasing the risk of a "thoracic rupture".
"His history of bulking out at the gym made me suspect he had been taking steroids for a long time - his upper-body muscles were enormous."
Gajdos, who was born in Slovakia, was an apprentice programmer and was studying at Weston College.
Desana Krajcikova, Mr Gajdos' mother, said her son was loved and missed by the community in Weston-super-Mare.
"He was known and loved by many people. Burying your son isn't something anyone should ever have to do, but we got the verdict we wanted.
"Andrej was a very keen bodybuilder with aspirations to become the new Rock... he will never reach that height now."
Dr Peter Harrowing, the assistant coroner, recorded a narrative verdict, saying he could not be sure that steroid use contributed to Mr Gajdos' death.
The medical cause of death was a ruptured thoracic aorta.
