Illegal steroids are often cut with cheaper but more potent steroids. Illicit steroid users often take far higher dosages than people on prescribed testosterone. There are also different molecular ‘structures’ of testosterone, and the stuff produced in illicit labs is usually a cruder old-fashioned form. Cutting edge industry leaders like Actavis produce a molecular testosterone that is quite different from the kind that was made 40 years ago. The black market producers are using archaic techniques and chemistry that produces what would be considered a messy product by the big boys of pharma.

**Edit**: poorcel black market steroid users are mad downvoting, but what I speak is the truth. Get some health insurance and stop taking that bathroom test.
