Description

    Tirzepatide, known also as LY3298176, represents a groundbreaking development in the pharmacological management of type 2 diabetes (T2D) and obesity. It’s a synthetic peptide that functions as a dual agonist for both the glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors. This dual mechanism is significant because it mimics the effects of endogenous GIP while simultaneously promoting cAMP synthesis at the GLP-1 receptor, leading to a synergistic effect. This results in enhanced insulin response and reduced glucagon levels, outperforming the impact of either GIP or GLP-1 therapies when used independently.

    Tirzepatide is a 39 amino acid long peptide, which includes a C20 fatty di-acid moiety. This design grants it an extended duration of action, allowing for a once-weekly dosing regimen in humans. Its efficacy and safety in improving blood sugar control have led to its approval by the United States Food and Drug Administration (USFDA) in May 2022 for treating T2D. This marked it as the first dual GLP-1 and GIP receptor agonist for this purpose.

    On arrival

    Inspect the vial before storing it. Check that the lot number on the label matches the lot number on the Certificate of Analysis in your order. If they do not match, do not use the material — contact us and we will replace it.

    Returns

    We do not accept returns on opened vials. Once material has left our cold chain we cannot verify how it was stored, and we will not resell a vial whose handling history we cannot account for. That restriction is the point of the brand, not an exception to it.

    What we do replace

    • Material that arrives damaged, compromised, or with a broken seal.
    • A lot number that does not match its Certificate of Analysis.
    • An analytical result outside the specification stated on the CoA.
    • The wrong compound or the wrong quantity.

    Report any of the above within 14 days of delivery with photographs and your order number. Verified claims are replaced or refunded in full, including shipping. We do not argue about this.

    Unopened vials

    Unopened, unrefrigerated-in-transit vials may be returned within 14 days for a refund less shipping, at our discretion and subject to inspection. Returned material is destroyed, not restocked.

    Supplied as a raw material for laboratory research and formulation development. Not for human or veterinary use. Not for resale to consumers as supplied.

    Compliance & research use

    Research use only

    Supplied as a raw chemical for laboratory research and formulation development. Not a drug, supplement, cosmetic, food, or medical device. Not evaluated by the FDA.

    Not supplied for

    • Human or veterinary use.
    • Diagnostic, therapeutic, or cosmetic application.
    • Resale to consumers as supplied.

    Why there are no claims here

    You won't find a mechanism of action on this page. That absence is deliberate. We report what we can measure — identity, purity, mass, sequence — and omit everything we cannot. If you ask us for dosage or administration guidance, we will decline.

    Who may purchase

    Buyers attest at checkout that they are 21 or older, are purchasing for research or formulation use, and accept full responsibility for safe handling and lawful use. Trade names and INNs are used solely to identify the chemical substance.

    For laboratory research and formulation development use only. Not for human or veterinary use. Not a drug, cosmetic, or food. Not for resale to consumers as supplied.

    Every lot is analysed by an independent US laboratory before release. Identity, purity and lot authenticity are verified against retention-time and parent-ion mass references. We do not grade our own work.

    Analytics · Every lot

    How we know it is what we say it is

    Two independent questions have to be answered before a vial leaves the building: is this the right molecule, and how much else is in there. They are answered by different instruments, and both answers ship with the material.

    • Identity — mass spectrometry. The observed mass is compared against the theoretical mass of the target sequence. A mismatch is a different compound, not a variation.

    • Purity — reverse-phase HPLC. The main peak is integrated against total peak area. The reported figure is that integration, not a specification we hope to meet.

    • Lot-matched, not batch-typical. The certificate you receive describes the vial you receive. A representative CoA from a previous lot is not evidence.

    • Retained and retrievable. Every certificate is QR-resolved and held a minimum of five years, so a result can be produced years after the vial is gone.

    Manufacturing · Chain of custody

    From resin to vial

    Nothing here is proprietary. It is the standard route, run properly and documented at each step — which is the entire difference between a supplier and a reseller.

    01

    Synthesis

    Solid-phase peptide synthesis. The sequence is assembled residue by residue on a resin support, then cleaved.

    02

    Purification

    Preparative reverse-phase HPLC. Truncated and deletion sequences are separated from the target and discarded.

    03

    Lyophilization

    Freeze-dried to a stable powder cake. No solvent, no carrier, no excipient added.

    04

    Lot control

    The finished lot is analysed, assigned a number, and tied to its certificate. That number is on the vial you receive.

    Documentation · The product

    The paperwork is the product

    A buyer sees the website once. They hold the vial every time, and they hold the certificate for years afterwards.

    • Certificate of Analysis — lot-matched, HPLC purity, identity by mass spectrometry.

    • Safety Data Sheet — handling, storage and disposal under laboratory conditions.

    • Identity block — CAS, molecular weight, sequence. A peptide without a CAS and an MW is not a product.

    • QR-resolved verification — publicly retrievable, retained a minimum of five years.

    • Supplier traceability — so our paperwork can become part of your safety file.

    Handling · Laboratory conditions

    Keeping it intact

    Peptide integrity is lost to heat, light and repeated freeze-thaw long before it is lost to time. Handle accordingly.

    Storage

    Lyophilized, at −20 °C, protected from light. Stable for extended periods in this state.

    Reconstitution

    Performed under laboratory conditions appropriate to the intended research application. Aliquot to avoid repeated freeze-thaw.

    Stability

    Reconstituted material is markedly less stable than lyophilized. Prepare what the work requires.

    Disposal

    Dispose of in accordance with local regulations for laboratory chemical waste. See the SDS.

    Standard of supply

    What to ask any supplier

    These are the questions a serious buyer asks before the first order. If a supplier cannot answer them in writing, the price is not the relevant variable.
