Buy Tirzepatide in the USA
Tirzepatide — a dual GLP-1 / GIP receptor agonist — supplied for laboratory research. ≥99% HPLC purity, batch-matched third-party COA, cold-chain packaging.
About This Compound
Tirzepatide is a synthetic dual GLP-1 / GIP receptor agonist engineered by Eli Lilly and one of the most-cited incretin-family research peptides in the current metabolic-pharmacology literature. Supplied here strictly as a research chemical for in-vitro receptor-binding, cellular-signalling, and preclinical-model investigation.
Structurally, Tirzepatide is a 39-amino-acid engineered analogue with a C20 fatty diacid side chain on Lys20 for extended in-vivo half-life in preclinical animal models. Molecular weight ~4813.5 Da.
Our Tirzepatide is synthesized by SPPS with orthogonal protection and on-resin lipidation, purified by preparative reverse-phase HPLC to ≥99%, identity-confirmed by ESI-MS, and endotoxin-tested below 0.5 EU/mg by LAL. Every lot ships with a batch-matched Verum Analytics third-party COA.
Presented as a lyophilized white powder in septum-sealed vials for reconstitution with bacteriostatic water for laboratory use.

Frequently Asked Questions
Where can I buy Tirzepatide in the USA?▾
BioInfinity is a US-based research peptide supplier shipping Tirzepatide same-day from our Manhattan facility. Every vial ships with a batch-matched third-party Certificate of Analysis (COA) and includes cold-chain packaging when the transit route requires it.
What purity is your Tirzepatide?▾
Our Tirzepatide is ≥ 99% pure by reverse-phase HPLC, identity-confirmed by mass spectrometry, and endotoxin-tested via LAL assay. The exact assay values for the batch you receive are published on your product page and are also included as a printed COA in the shipment.
Do you provide a Certificate of Analysis (COA) with Tirzepatide?▾
Yes. Every shipment includes a batch-matched COA from an independent third-party laboratory (Verum Analytics, Switzerland). You can also verify the batch online in our public COA library using the verification code printed on the vial label — no login required.
How is Tirzepatide shipped?▾
USPS Priority (2-3 business days) or UPS Ground (3-5 days). Cold-chain packaging with gel packs sized to the transit route. Discreet plain unbranded outer boxes — the label carries only the address and standard postal markings.
What payment methods can I use for Tirzepatide?▾
Credit / debit card (Visa, Mastercard, Amex, Discover), Zelle, Venmo, Cash App, USDC stablecoin, and wire transfer for institutional orders. Zelle typically clears fastest and is the most common payment method our repeat customers use.
Is Tirzepatide FDA-approved or intended for human use?▾
No. Tirzepatide is not FDA-approved for any therapeutic indication. BioInfinity supplies Tirzepatide strictly for in-vitro laboratory research. It is not intended for human, veterinary, or in-vivo use of any kind.
How should I store Tirzepatide once it arrives?▾
The lyophilized (freeze-dried) powder is stable at 2–8 °C refrigeration for normal-use timeframes. For extended storage until the expiry date, store at −20 °C protected from light. Once reconstituted for bench work, refrigerate at 2–8 °C and use within 3–4 weeks per general peptide-handling literature.
Can I get a bulk / institutional discount on Tirzepatide?▾
Yes. Professional accounts qualify for tiered volume discounts. Create a Professional account at /account, or e-mail [email protected] with your institution and PO details.
What is your return policy on Tirzepatide?▾
Unopened, cold-chain-intact vials can be returned within 14 days of delivery for a refund minus return shipping. Opened vials are non-returnable due to the nature of the product. If a shipment arrives damaged or thawed, contact us within 48 hours for a free replacement.
How fast do orders for Tirzepatide ship?▾
Orders placed by 3:00 PM ET Monday–Friday ship same-day from Manhattan. Weekend orders ship the following Monday. You'll receive a tracking number by email the moment the label is scanned by USPS or UPS.
Do you ship Tirzepatide internationally?▾
We ship domestically within the 50 United States plus Puerto Rico and the US Virgin Islands. International shipments are evaluated case-by-case and require additional documentation — please contact [email protected] for a quote.
Where can I read your Tirzepatide COA?▾
Every batch's COA is browsable from our public /coa-library page. You can also click the "View COA" button on the Tirzepatide product page (/product/tirzepatide) or on the vial label itself, which carries a QR code that resolves to the batch's verification page.
What sizes does Tirzepatide come in?▾
5 mg, 10 mg, and 15 mg septum-sealed lyophilized vials. Institutional bulk sizes on request.
How is Tirzepatide different from Semaglutide and Retatrutide?▾
Semaglutide is a GLP-1 monoagonist. Tirzepatide is a dual GLP-1/GIP agonist (two receptors). Retatrutide is a triple GLP-1/GIP/glucagon agonist (three receptors). Each is a distinct tool compound in incretin-family receptor pharmacology.
