There was a program on Belgian TV called "Trafiek Axel".
In this series the guy who host the series is going undercover to uncover the different traffics behind for example: buying a wife online, human trafficking, buying organs off market, the paid animal hunt in Afrika and many more. The last episode was about buying steriods.
In that show they find a young guy (28 years old) and follow him medically when he does his first few weeks of roids ever.
They follow him in the gym while he's working out, they take all kind of medical tests before the roids and the same tests when the first cure is over.
The guy never did roids before and his medical tests after that first cure were actually insane.
Liver already damaged, balls already damaged and other things I forgot.
So I would not recommend doing it ever.
When the doctor told him his medical results you could see he was pretty shocked about the bad results and told the show he wouldn't do roids again but sadly, 8 months after the show he was still taking roids because once you see yourself lift more and get bigger you won't ever go back to lifting natural.
