Health Canada is warning Canadians about the online retailer Steroid Hub Canada because it is selling unauthorized health products that may pose serious health risks. The unauthorized products on the website are promoted for bodybuilding and include anabolic steroids, growth hormones and Selective Androgen Receptor Modulators (SARMs). Other products are promoted for uses such as weight loss and sexual enhancement. Some products are in an injectable format. Many are labelled to contain prescription drugs or controlled substances. One of the products is an unauthorized version of "Saizen," which is a prescription growth hormone drug (somatropin) authorized by Health Canada and administered by injection. Selling unauthorized health products in Canada is illegal. Health products that have not been authorized by Health Canada have not been assessed for safety, effectiveness and quality, and could pose serious health risks. For example, unauthorized health products could contain ingredients not listed on the label, including prescription drugs, possibly at doses exceeding maximum recommended amounts. Prescription drugs should only be used under the advice and supervision of a healthcare professional, because they are used to treat specific conditions and may cause serious side effects. Specific drug ingredients may be subject to additional restrictions as outlined in the Food and Drugs Act and the Controlled Drugs and Substances Act. This may include the need for a prescription from a health care practitioner, the application of specific controls to allow for professional direction and supervision in their use, or the application of additional controls on the sale and storage of the product.
