"The first time I took steroids, I was with my brother. It was in my bedroom. I must have been 14, maybe just turning 15."

Macaulay Dodd was an angry, mixed-up teenage boy reeling from the break-up of his parents' marriage and desperately looking to his gym-going older brother and friends for guidance on how to weather the path to adulthood.

As he plunged that needle into his buttock for the first time, he could not have known that within a few short years he would be at the heart of one of the UK's biggest illegal steroid gangs and would be the one cooking up drugs to the tune of £1.2m.

His story is revealed in BBC series Confessions of a Steroid Gang, which documents the rise and fall of a drugs operation run by Macaulay and his dad, Andrew Dodd, and undone, in part, by a dog grooming shop they set up to launder all the cash they were making.

Andrew says, at the time, he did not class himself as a criminal. Yet the pair took significant steps to cover up their activities from police and those who knew them.
