T30 — Tirzepatide 30mg
$
Research Overview
Tirzepatide (CAS 2023788-19-2), known in the development literature as LY3298176, is a synthetic 39-residue peptide engineered from the native GIP sequence and acylated at Lys20 with a C20 fatty diacid through a γGlu-2×AEA linker. It is characterised in published pharmacology as a dual agonist at the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor, with unbalanced potency between the two — closer to native GIP at the GIP receptor than to native GLP-1 at the GLP-1 receptor.
α-Aminoisobutyric acid (Aib) occupies positions 2 and 13, blocking dipeptidyl peptidase-4 cleavage, while the diacid chain drives reversible albumin binding and a long circulating half-life. Molecular formula C225H348N48O68, average molecular weight approximately 4813 Da. It is a standard comparator in incretin-receptor assay work alongside retatrutide and the GLP-1 mono-agonists.

Lot and presentation
This listing is supplied as 30mg × 10 vials, lyophilised powder in sealed vials. The current lot is released at 99%+ chromatographic purity, against an independent Janoshik certificate of analysis reporting mass by HPLC-UV against a reference standard. Peptide content and purity are reported separately because they measure different things — content is how much material is in the vial, purity is what fraction of that material is the target sequence.
Handling and storage
Lyophilised material tolerates ambient temperature in transit but should be moved to -20°C on arrival for long-term storage, protected from light and moisture. Allow a vial to reach room temperature before opening so that condensation does not settle on the powder. Once reconstituted, material of this class is normally held at 2-8°C and used within a short window; repeated freeze-thaw cycles degrade it.
Research use only
This material is supplied strictly for in-vitro laboratory research and analytical reference use by qualified professionals. It is not a drug, not a dietary supplement and not a cosmetic. It is not intended for human or veterinary use, for diagnostic purposes, or for administration to any living organism. Nothing on this page describes an effect in humans.

Testing is ordered by the manufacturer that produces this lot, so the laboratory names the manufacturer as its client rather than BMS Labs; the report is published unchanged. The endotoxin figure is a contamination measure only — it is not a sterility result and does not indicate suitability for use in a living organism.
Questions about this lot
- Does this lot come with a certificate of analysis?
- Yes. The lot currently shipping was analysed by Janoshik Analytical as lot T30-260830 under report number 229509, analysed 9 September 2026. The figures are published on this page exactly as the laboratory reported them, and the report can be looked up at the laboratory itself.
- What purity does the report show?
- The report gives 99.944% / 99.962% / 99.980% by HPLC, measured on separate vials from the same lot. Purity describes what fraction of the material is the target compound; content, reported separately above, describes how much material is in the vial.
- Can I verify the report myself?
- Yes. Every report on this site links to the laboratory's own record, so the figures can be checked against Janoshik rather than against us. Our guide on verifying a Janoshik report explains which fields to compare.
- What does the endotoxin figure mean?
- Endotoxin is a measure of bacterial contamination in that lot, reported here as <1 EU/vial from a separate analysis with its own report number. It is not a sterility result and does not make the material suitable for use in a living organism.
- How should this material be stored?
- As supplied, the lyophilised powder is kept cold, sealed, dry and out of the light, and the vial is allowed to reach room temperature before it is opened, so that moisture does not condense on the cold solid. Our storage and handling guide covers the details.
- How and when does it ship?
- Orders ship from our US warehouse on the next business day after payment is confirmed on-chain, by USPS, within the United States only. US shipping is free with no minimum order, and typical transit time is three to seven business days.
- What is this material sold for?
- Laboratory and analytical research use only. It is not a medicine, not a supplement, and not for human or veterinary use. Orders are accepted on that basis.
