Is anabolic steroids illegal

It depends on the country you are in but generally anabolic steroids are illegal unless you have a prescription from a doctor.

Most modern countries they are illegal, in Thailand they are legal, and in the UK the law seems to change a lot, they were at one point legal for personal use but i believed they have now changed it to a class c drug.

Doctors don't provide anabolic steroids (anabolic meaning muscle growth, which only has one use to build muscle)
