Buy Semaglutide in the USA
Semaglutide — a long-acting GLP-1 receptor agonist — supplied for laboratory research. ≥99% HPLC purity, batch-matched third-party COA, cold-chain shipping from Manhattan.
About This Compound
Semaglutide is a long-acting synthetic GLP-1 receptor agonist engineered by Novo Nordisk and one of the most extensively cited incretin-family peptides in the current preclinical and receptor-pharmacology literature. BioInfinity supplies Semaglutide strictly for laboratory research — receptor-binding studies, in-vitro cellular-signalling, and preclinical metabolic-model investigation.
Structurally, Semaglutide is a 31-amino-acid modified glucagon-like-peptide-1 analogue carrying a C18 fatty diacid side chain on Lys26. The modification extends preclinical in-vivo half-life relative to native GLP-1 in animal models. Molecular weight ~4113.6 Da.
Our Semaglutide is synthesized by SPPS with orthogonal side-chain protection followed by on-resin lipidation, purified by preparative reverse-phase HPLC to ≥99%, and identity-confirmed by ESI-MS. Endotoxin below 0.5 EU/mg by LAL. A batch-matched third-party Verum Analytics COA ships with every order.
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 Semaglutide in the USA?▾
BioInfinity is a US-based research peptide supplier shipping Semaglutide 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 Semaglutide?▾
Our Semaglutide 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 Semaglutide?▾
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 Semaglutide 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 Semaglutide?▾
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 Semaglutide FDA-approved or intended for human use?▾
No. Semaglutide is not FDA-approved for any therapeutic indication. BioInfinity supplies Semaglutide strictly for in-vitro laboratory research. It is not intended for human, veterinary, or in-vivo use of any kind.
How should I store Semaglutide 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 Semaglutide?▾
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 Semaglutide?▾
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 Semaglutide 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 Semaglutide 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 Semaglutide COA?▾
Every batch's COA is browsable from our public /coa-library page. You can also click the "View COA" button on the Semaglutide product page (/product/semaglutide) or on the vial label itself, which carries a QR code that resolves to the batch's verification page.
What sizes does Semaglutide come in?▾
2 mg, 5 mg, and 10 mg septum-sealed lyophilized vials. Institutional bulk sizes on request.
How does Semaglutide differ from Retatrutide and Tirzepatide?▾
Semaglutide is a single-receptor GLP-1 monoagonist. Tirzepatide is a dual GLP-1/GIP agonist. Retatrutide is a triple GLP-1/GIP/glucagon agonist. All three are in the GLP-family research-peptide space.
