OTTAWA - Health Canada is warning Canadians not to use the dietary supplement MdMt, or any other supplements containing the synthetic steroids methyl-1-testosterone or methyldienolone that are obtained without a prescription, due to potentially serious health risks including reduced fertility and liver disorders.
MdMt, manufactured by BMF Hardcore, New York, is promoted as a dietary supplement for body building, and is not authorized for sale in Canada. Health Canada has received one domestic adverse reaction report in which a 38-year-old male developed azoospermia, a condition where the semen contains no sperm, while taking MdMt. Previously, Health Canada received one case report of severe liver toxicity associated with the use of another product containing methyl-1-testosterone.
Methyl-1-testosterone and methyldienolone may also be labelled as 17alpha methyl-17beta-hydroxy-andros1-ene-3-one and 17a-methyl-17beta-hydroxyestra-4,9(10)dien-3-one, respectively.
MdMt contains both methyl-1-testosterone and methyldienolone, which are controlled substances in Canada and should be dispensed and used only under strict medical supervision. Products containing methyl-1-testosterone or methyldienolone are not authorized for sale in Canada without a prescription. However, follow-up from the domestic adverse reaction report associated with MdMt indicates that Canadians have access to this product through retail outlets in Canada. This product may also be available for purchase over the Internet. Health Canada is referring this matter to the appropriate legal authorities for follow-up, and is taking action to prevent further importation of this product into Canada. In addition, unapproved natural health products that are for sale in Canada are subject to compliance action in accordance with the Compliance Policy for Natural Health Products.
Canadians using MdMt or any other supplements labelled as containing methyl-1-testosterone or methyldienolone and obtained without a prescription are advised to stop taking the product immediately and consult with a health care professional if they have health concerns.
Consumers should contact the Health Products and Food Branch Inspectorate at 1-800-267-9675 if they find MdMt or any other products containing methyl-1-testosterone or methyldienolone being sold at a Canadian retail outlet without a prescription.
Consumers requiring more information about this warning can contact Health Canada's public enquiries line at (613) 957-2991, or toll free at 1-866-225-0709.
