kind of doubt it. They do drug testing and steroids don't do a lot of boxers' mobility. Would steroids really help punching power that much anyhow? I see the logic, that yeah you're stronger so you can throw your fist harder, but I don't know if that's completely true. You'd get more bulky, which could slow your punch down.
mike tyson did do steroids, tommy morrison took steroids and don king payed ppl off to say tyson was negative for steroids holyfield also got away with this but was later reported and don king also payed ppl to give tommy morrison a false posotive for HIV because he was a threat to tysons career. When tyson was found out he said he didnt want to talk about it hes words were... "iv taken alot of things in my life but thats no bodys business and i dont wanna talk about it" These are all facts hes steroid use appariently also took place in prison but he was taking a drug called lithium at the time and lithium mixed with steroids causes major mood swings and the end result can be depression and breakdown. Before he came to cus damato he was overweight. this is often overlooked but this is from kevin rooney and teddy atlas's own mouths he was made to lift weights along with circuit training and also running this is how he leaned out but as soon as he got to cus damatos house he was put on a strict diet like everyone else this was for boxing and being healthy but that played a big part in the weight loss. him being overweight caused him to be 197lbs at the age of 13 and 14. he was put on a high protien diet to build muscle because he was made to lift weights because he was shorter and cus knew it would give tyson a different look in the ring. HE DID LIFT WEIGHTS HE AND TRAINERS HAVE CONFIRMED THIS.
but steroids isnt very effective in the sport of boxing only with hand speed. have u ever noticed for a heavyweight tyson was very very fast. he was fast as a kid but even faster afterwards. steroids also explain tysons sexual desire for women. note: im not trying to put tyson down as he will always be a boxing legend no matter what and iam a big fan of his. my findings were all fact due to extensive research
