that featured the steroids ad.
He also told us that his kids are aged just 11 and 12 years old, and said: "After seeing that unskippable ad, they had so many questions. Had a lot of explaining to do afterwards."
It's important to note that when you click the ad, you're presented with "legal alternatives" to steroids, rather than the real thing.
However, YouTube's advertisement offers the opportunity "buy steroids" without the need for a prescription.
The names of the products are very similar to actual steroids too.
For instance, one fitness supplement is called 'D-Bal', which sounds similar to 'D-Bol', the street name for the steroid Dianabol.
Then there's 'Trenorol", which sounds like a mix of steroids Trenbolone and Dianabol.
The ad took users to a fitness gear website called Crazy Bulk, which promises to help you "build your ultimate body fast".
YouTube told The Sun that it had "taken action" on the ad following our report.
A spokesperson added: "We have policies in place to govern which ads may appear on YouTube.
"We enforce these policies rigorously and when a violation is brought to our attention, we take swift action."
This isn't the first time YouTube has been caught up in an advertising controversy.
Back in September, the site was accused of cashing in on "child exploitation" clips by placing ads on videos of children in disturbing situations.
Then in November, the company was warned of being in danger of becoming a "sweet shop for paedophiles" for making money from clips of scantily clad children.
