Many who want the "perfect" body now turn to steroids. The numbers who actually inject are rising rapidly. Heroin, it seems, now takes second place when it comes to needles. Just how bad is it and what are the risks?

Joining us on Skype from Middlesbrough is Andrew Richardson, a blogger who's written about drugs in sport; Joe Kean, independent researcher into steroid misuse who is also a former steroid user; Callum Jackson, personal trainer and ex- professional cricketer and Roy Jones, a nurse who specialises in substance abuse.

Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRT World.
