Overview
Methandienone, sold for years as Dianabol, was one of the first oral anabolic steroids made for medical use. It is no longer prescribed in North America but remains widely recognised.
This listing is Genetix Pharma Dianabol 20mg (20 mg), photographed as we ship it and priced in Canadian dollars.
How it works
Methandienone is testosterone with an extra double bond and a 17-alpha methyl group, which lets it survive oral use. It binds androgen receptors, converts to a potent estrogen, promotes fluid retention and suppresses natural testosterone.
Clinical reference
Methandienone was withdrawn from the North American market decades ago. Historic labelling for anabolic support used about 5 mg a day. There is no current approved dose.

Combinations and interactions
- Its estrogen conversion means estrogen-related side effects are common.
- Interactions: can increase the effect of warfarin and change blood sugar control.
- Combining with other oral steroids adds to liver strain.
Risks and side effects
- Fluid retention and blood pressure. Rapid water weight and higher blood pressure are typical.
- Liver. Elevated liver enzymes; avoid alcohol and other liver-stressing drugs.
- Gynecomastia. Estrogen-sensitive breast tissue growth.

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.
