Gone are the days where you could go to a doctor and get a script to buy steroids from a pharmacy, due to steroids being abused by athletes and bodybuilders they are now illegal. The only way to buy steroids now is on the black market, either from a dealer or from an online source. When steroids were legal and were purchased from a pharmacy, the only steroids you could get were pharmaceutical grade which were extremely high quality and worked far better than the “underground” stuff. Today pharmaceutical steroids are harder to get hold of and cost a lot more, for this reason many people opt for black market steroids which usually are lower quality and can cause infections due to them being produced in an non-sterile environment. Only injectable steroids need to cause concern when purchased from an underground lab, oral steroids don’t need to be produced in a sterile environment.
Like other AAS, drostanolone is an agonist of the androgen receptor (AR).  It is not a substrate for 5α-reductase and is a poor substrate for 3α-hydroxysteroid dehydrogenase (3α-HSD), and therefore shows a high ratio of anabolic to androgenic activity.  As a DHT derivative, drostanolone is not a substrate for aromatase and hence cannot be aromatized into estrogenic metabolites .  While no data are available on the progestogenic activity of drostanolone, it is thought to have low or no such activity similarly to other DHT derivatives.  Since the drug is not 17α-alkylated , it is not known to cause hepatotoxicity .
