Tirzepatide

Tirzepatide is a research compound supplied for laboratory research use only. Its verified identity data is a molecular weight of 4,813 g/mol, CAS 2023788-19-2, PubChem CID 166567236. It is listed under GLP-1 & Metabolic.

No safety profile has been established for Tirzepatide, and nothing on this site should be read as saying otherwise. What we can tell you is narrower and verifiable: no third-party assay exists for this product yet, so it carries no purity claim here. An HPLC purity result is a statement about identity and purity in a tested lot. It does not measure sterility, endotoxin or heavy metals, and it is not a safety assessment. Health Canada has published advisories on unauthorized injectable peptides, and you should read the research use disclaimer before ordering.

Health Canada regulates injectable peptides as drugs, and it has stated in writing that labelling one “for research use only” does not remove it from that regulation. The regulator has published advisories naming specific compounds, seized product from Canadian sellers, and obtained a court injunction against at least one seller. Most suppliers present research use labelling as though it settles the question. On the regulator’s own published statements, it does not, and we would rather say so than let you assume otherwise. Read the disclaimer in full.

No. Tirzepatide is a peptide, not an anabolic steroid, and the two are different classes of molecule with different structures. Its molecular weight is 4,813 g/mol. Steroids share a four-ring carbon skeleton; peptides are chains of amino acids.

Use the peptide calculator: enter the vial’s total mass and your target concentration, and it returns the volume of bacteriostatic water to add. That is arithmetic, not a dosing instruction, and it is the step people most often get wrong. Reconstituted material has a much shorter usable life than sealed powder.

Not yet, and we will not imply otherwise. No third-party assay exists for this product, so it carries no purity claim anywhere on this site. When an assay is done, the figure and the full report go up together and the batch reference appears on the packing slip. The lab results index shows everything we do hold a certificate for.

Here, shipped across Canada, with the batch certificate reference on the packing slip. The thing worth comparing between Canadian suppliers is not price but what each one publishes: whether a third-party report exists, whether it is shown in full or reduced to a percentage, and whether it can be tied to the lot you received.

Prices are on the product page in Canadian dollars, and strengths vary. Compare price per milligram rather than price per vial, because strengths differ between suppliers and a cheaper vial is often a smaller one. A vial with no assay and no batch reference is not the same product at a lower price, it is a different proposition.

We do not answer that here, and the reason is not evasiveness. Describing what a compound does, in a shop that sells it, is a therapeutic claim, and that is the line between describing a research compound and marketing an unlicensed drug. What we publish instead is identity, purity, the testing laboratory and the limits of the assay. Where published research exists, the product page cites it and links the source so you can read it yourself rather than take our summary of it.

They are different compounds with different identity data and different research literature, and neither substitutes for the other. The comparison worth making is on what each one is and what evidence exists for it, which is set out on both product pages. See Semaglutide.
