Health Canada is warning consumers not to buy unauthorized injectable drug products from Canlab Research because they may pose serious health risks. The products are promoted as peptides and are sold online via Canlab Research websites including www.canlabresearch.com and www.canlab.net . Peptides carry out a range of important functions in the body. Some peptides can be produced for use in medications. Examples of injectable prescription drugs available for sale on Canlab Research websites include oxytocin and triptorelin. More information on the specific risks for these drugs can be found in the Background section below. Most synthetic injectable peptides are regulated as prescription drugs in Canada and require a prescription from a licenced health care professional. Selling unauthorized health products in Canada is illegal. Unauthorized health products have not been approved by Health Canada, which means that they have not been assessed for safety, efficacy and quality and may pose a range of serious health risks. For example, they could contain high-risk ingredients, additives or contaminants that may or may not be listed on the label. Unauthorized injectable drugs also carry significant risk due to potential for infection, allergic reactions, and poor outcomes. Prescription drugs should only be used under the advice and supervision of a health care professional because they are used to treat specific conditions and may cause serious side effects. Health Canada has ordered Canlab Research to stop advertising and selling all unauthorized health products and will take further compliance and enforcement action to protect consumer health and safety if necessary. Health Canada is also working with the Canada Border Services Agency to help prevent importation of these unauthorized health products.
