How it works

Mesterolone is a DHT derivative that binds androgen receptors and sex hormone binding globulin (SHBG). It does not aromatise and has little effect on the body’s own LH at usual doses.

Canadian legal status

Anabolic steroids are listed in Schedule IV of the Controlled Drugs and Substances Act. Simple possession of a Schedule IV substance is not itself an offence, but importing, exporting, producing or selling one without authorisation is. Anabolic agents are prohibited in tested sport. Laws change, so check the current rules for your situation.
