the most popular pro hormone is andro which was popularized years ago by mark mcgwire.
beastdrol, superdrol are not pro hormones at all.. they are legit designer steroids.
now the supps that are legally sold at mr supps like helladrol, katanadrol etc are strong and just as strong as any oral AAS. i would consider those a cross between pro hormone and designer steroids. it would be a major mistake for anyone to take them and not run a proper PCT or be taken by a teenager.
