Drug Identification Number (DIN), Canada

A Drug Identification Number (DIN) is the eight-digit number Health Canada assigns to an authorized drug sold in Canada. It is printed on authorized drug labels. A lyophilized research peptide on this site does not carry a DIN because it is not sold as an authorized drug. A Janoshik report, an HPLC percentage, and the words research use only do not add a DIN after the fact.

If a purchasing form asks for a DIN, the honest entry for these catalogue materials is that there is none. The explanation lives in Are research peptides legal in Canada?, on the research use only term, and in the FAQ on a catalogue vial versus a clinical drug product. This glossary entry is not legal advice.

An authorization identifier, not a test result

A Drug Identification Number is the eight-digit number Health Canada assigns to an authorized drug sold in Canada. It is printed on authorized drug labels. It answers an authorization question. A Certificate of Analysis answers a batch-testing question. An HPLC area percent, a mass, an endotoxin unit, and a Janoshik task identifier are not eight-digit authorization numbers, and they do not become one when they are copied onto a purchasing form. A lyophilized research peptide on this site does not carry a DIN because it is not sold as an authorized drug.

If a form has a DIN field, the honest entry for these materials is that there is none. Leaving the field blank, or writing that the catalogue solid is not an authorized drug, is more accurate than pasting a lot number into the DIN box. This entry is not legal advice. The explanation lives in Are research peptides legal in Canada? and on the research use only term. The contract is the Terms.

Catalogue materials that are easy to misfile

High-demand shop URLs are still RUO listings. BPC-157 10 mg, retatrutide, tirzepatide, semaglutide, and GHK-Cu 50 mg do not pick up a DIN because a public trial or a review article used a similar name. Sponsor trial material and a lyophilized catalogue lot are different objects. The trial recap, where this site has one, stays on the research hub. The vial stays on the shop URL. The lot file stays in the certificates library.

TB-500 10 mg is a useful stress test of the same rule. The single-peptide SKU has a purity anchor and no endotoxin line. Absence of an endotoxin line is not a hidden DIN, and presence of a blend PDF is not a DIN either. For the identity note, see What is TB-500?. Sequence length and lot mass are analytical. Authorization is the DIN question. Do not collapse them into one cell on the form.

Payment does not create the number

Interac e-Transfer and Canada Post Xpresspost are how a Canadian laboratory pays and receives. They are described on the procurement guide. A paid invoice is not an authorization. A tracking number is not an authorization. Research use only. Confirm the institution's purchasing rules before you order, and keep the DIN field aligned with what Health Canada has actually assigned.

Lot numbers are a different shape of identifier. A batch code on a Janoshik file, a cap colour, and a milligram fill identify a container. They do not identify an authorization. For the glossary line, see lot number. Cagrilintide 5 mg and Ipamorelin 10 mg illustrate the split: each can have a published analytical file and still have no DIN. File the analytical identifier in the receiving log. Leave the authorization field honest. The founder record for who publishes the library is Alice Kay, Ph.D.

Eight digits on an authorized drug label are the DIN pattern. A lot code, a task identifier, and a shop slug are different shapes. Do not force them into the authorization field to make a form look complete.
