WRESTLING killer Chris Benoit was so obsessed with steroids - he even injected his seven-year-old son with growth hormone.
Daniel - who was murdered by Benoit along with mum Nancy before the WWE star committed suicide - was found with needle marks in his arms.
Fayette County District Attorney Scott Ballard confirmed the findings, saying Daniel had been given growth hormones for some time because Chris and Nancy considered him to be undersized.
He added: "The boy was very small, even dwarfed."
Daniel was also said to have Fragile X Syndrome, a condition which can lead to behaviour problems, autism, hyperactivity and in some cases mental retardation.
Sources in the States say Chris, who was a lot smaller than your typical wrestling superstar, took steroids throughout his career as he was worried about losing work due to his size.
One reported: "This was decades and decades of steroid use with no cycling - even when undergoing neck surgery.
"And that's not healthy in any way."
Investigators say Chris illegally received deliveries from a Florida business called MedXLife.com that sold steroids, human growth hormone and testosterone on the Internet.
Six people at the pharmacy, including two of the owners, have already pleaded guilty to supplying sport stars with drugs and 20 more have been arrested.
Since the death of Benoit's pal and fellow MedXLife.com customer Eddie Guerrero from heart failure in November 2005 - brought on by years of alcohol, drug and steroid abuse - the WWE instituted a strict testing procedure.
However, crucially, the company's 'Wellness Policy' allowed for prescribed steroids, meaning use is still rife.
It states: "The WWE policy prohibits the use of performance-enhancing drugs, as well as other prescription drugs which can be abused, if taken for other than a legitimate medical purpose pursuant to a valid prescription from a licensed and treating physician."
Smaller wrestling groups in the US and UK don't test at all.

A source in the industry told us: "Wrestlers have an insane schedule, with no off season and little to time to fully heal injuries.
"On top of that they are under immense pressure from bosses and fans to have superhuman physiques.
"So they turn to steroids in order to look better and return to action more quickly after injuries.
"I would say almost every single wrestler in the business today has been on 'the gear' at one point in their career, and many still are even after all the shocking deaths we've seen.
"Some are able to move on after they achieve the body they want but others, like Benoit, become addicts.
"If they say a physique is too good to be true then it probably is."
He added: "Steroids are not hard to get hold of legally. You just have to find a quack who will prescribe them so they can hang out with the wrestlers and get some cool pictures for the wall.
"They are known as 'mark doctors' and have been around as long as wrestling itself."
It is unknown whether the killings were due to 'roid rage' and a full blood test is not due for around two weeks.
The WWE released a strongly wording statement saying: "Steroids were not, and could not, be related to the cause of death (asphyxiation).
"Authorities had no factual basis to speculate as to Benoit's state of mind, and rightly did not do so.
"A full Toxicology (blood test) report has not even been completed, so there is no current evidence that Benoit even had steroids or any other substance in his body."

, most are just trying to at least find some logical explanation as to why he did it.
