DIN (Drug Identification Number)
The eight-digit number Health Canada assigns to every authorised drug product; a compound without one has not been approved for sale as a medicine in Canada.
A Drug Identification Number is the eight-digit code that Health Canada assigns to a drug product when it authorises the product for sale. The number appears on the label of every prescription and over-the-counter medicine sold in Canada and can be looked up in the Drug Product Database, which lists the product, its manufacturer, its active ingredients and the conditions of its approval. A product without a DIN has not been authorised as a drug.
For research peptides the DIN is the clearest test of regulatory status. Ozempic and Wegovy carry DINs, so semaglutide is an approved medicine in Canada. Mounjaro carries one, so tirzepatide is approved. Egrifta carries one for tesamorelin. BPC-157, ipamorelin, retatrutide and most other compounds profiled here have no DIN and no authorised product, which is why they are sold for research use only.
The research-grade material sold on this site never carries a DIN, even for compounds that have an approved counterpart, because it is not the authorised product. Each profile's "Regulatory status in Canada" section states the position for that compound.
