Is Gen Pharama a dodgey brand?

[Frankrex]

Hi I have a supplier who has all Genpharma gear. I've brought it before didn't think it was to bad. But I was talking to a guy at my gym out different stuff. And when I mentioned gen pharma. He immediately was like no don't buy that stuff it's shit. It could be dek ect ect. Was really really against it. So yeah just wondering what everyone's opinions where? Cheers
