Tirzepatide is supplied here as a laboratory research compound in 14 sizes (5mg to 120mg), from $50.00 per vial, each lot documented with its identity method, purity method and test date. It is not an FDA-approved medicine. For laboratory research use only.
Identity and nomenclature
Tirzepatide is a synthetic peptide classified as a dual GIP and GLP-1 receptor agonist. Approved medicines containing this active ingredient exist and are dispensed only by prescription; the material listed here is a laboratory research compound and is not a medicine, not a substitute for one, and not for human or animal use.
Tirzepatide is also listed and searched as tirzepatide peptide, tirz, tirzepatide research peptide, peptide tirzepatide. Every one of those names refers to the same compound. A name is not an identity check, which is why the analytical record below carries more weight than the text on a label.
Because an approved prescription product shares this active ingredient, mislabelling carries unusual consequences. The record below documents what was tested rather than what a supplier claimed.
Frequently mistyped as tirzepitide, terzepatide, tirzeptide. Those spellings reach this same record.
The research on Tirzepatide
Status: Approved medicines exist — this material is not one of them. Tirzepatide is a dual GIP and GLP-1 receptor agonist. FDA-approved medicines containing tirzepatide exist and are available only on prescription, manufactured under pharmaceutical quality systems that a research-chemical supply chain does not replicate.

Current FDA guidance and regulatory status
The FDA declared the tirzepatide injection shortage resolved on 19 December 2024. With the shortage over, the agency's temporary enforcement discretion for compounded tirzepatide ended on 19 February 2025 for 503A compounding pharmacies and 19 March 2025 for 503B outsourcing facilities. Compounded tirzepatide is therefore no longer generally permitted, and research-grade material has never been a lawful route to human use at any point in that timeline.
Status verified 2026-08-25. Regulatory positions move; check the primary source before relying on any summary, including this one.
How is Tirzepatide identity and purity established?
Identity is established with orthogonal evidence — a mass-spectrometric measurement that matches the expected molecular mass, read alongside a chromatographic purity profile. A purity percentage on its own establishes neither identity nor quantity.
Purity is reported as a chromatographic area percentage from reverse-phase HPLC, stated together with the method and the date it was run. An area percentage quoted without its method is not a result.
Two numbers are routinely confused with each other. Purity describes how much of what is in the vial is the intended compound. Net content describes how much material is actually there. A vial can be 99% pure and still contain substantially less mass than its label states, which is why the record treats them as separate measurements with separate methods.

No lot documentation is published for Tirzepatide yet. Rather than display a placeholder certificate, this record shows the gap until each field has been verified against the lot in hand.
Storage and handling
Sealed lyophilised vials are held cold and protected from light. Once a solution is prepared, stability depends on the compound, the diluent, the concentration and the temperature, so laboratories date and label prepared solutions and record the preparation in their own notes.
For solution preparation arithmetic — concentration, per-graduation values and molarity — use the Tirzepatide solution calculator or the general vial concentration tool. Those tools cover laboratory measurement only and contain no administration guidance.

What an order actually costs
Say you need ten vials of Tirzepatide 10mg for a run of work. At $90.00 each that is $900.00 at list; the 10-vial tier takes 10% off, so it bills at $810.00 — $90.00 saved, and free standard shipping because the order clears $200. Twenty vials moves you to the 15% tier: $1530.00 instead of $1800.00, which works out at $7.65 per milligram against $9.00 at single-vial pricing. Volume pricing is applied per size, not across mixed sizes.
How to evaluate any supplier of Tirzepatide
This applies to us as much as to anyone else. Run these five checks before money moves.
- Verify the certificate at the laboratory, not the seller. Take the report's key or QR code to the issuing laboratory's own verification page. If it does not resolve, or resolves to a different product, the document is worthless no matter how convincing it looks.
- Check the certificate names the seller as its client. A report commissioned by somebody else tells you about somebody else's material, not about the vial in front of you.
- Match the lot on the certificate to the lot on the vial. A genuine report for a different lot is still the wrong report.
- Require a method beside every number. A purity percentage with no stated method and no test date is marketing, not a result.
- Confirm identity separately from purity. Purity describes how much of what is in the vial is the intended compound. It cannot tell you the compound is the right one — that takes mass-spectrometric evidence read alongside the chromatography.
Why regulatory status matters when you buy
Regulatory status varies by compound, formulation, intended use and jurisdiction. Listing a compound in this catalogue is not an approval, safety, efficacy, quality or suitability claim of any kind.
FOR LABORATORY AND IN-VITRO RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION. NOT FOR PERSONAL, MEDICAL, DIAGNOSTIC, THERAPEUTIC, OR RECREATIONAL USE.
