About this peptide

Semaglutide is a long-acting GLP-1 receptor agonist with two amino acid substitutions and a C18 fatty diacid chain attached to the lysine at position 26 via a γGlu-2xOEG linker. The fatty diacid modification supports albumin binding, extending plasma half-life to approximately one week. Researchers studying glucose-stimulated insulin secretion, satiety signalling, gastric emptying, and central reward pathways frequently use semaglutide as a reference GLP-1 receptor agonist. Supplied as a sterile-filtered lyophilized powder sealed under nitrogen. Most in-vitro protocols reconstitute at 1–3 mg/mL in sterile bacteriostatic water. Reconstituted material is typically stable for up to eight weeks under refrigeration. The HPLC chromatogram for the batch in your shipment is bundled with delivery.

Questions about Semaglutide 5mg

How is Semaglutide 5mg reconstituted?

+

Semaglutide 5mg is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

What is the HPLC purity of this batch?

+

Batch SG-2606 of Semaglutide 5mg is verified at 99.4% HPLC main-peak purity, with confirmation of molecular weight by LC-MS and endotoxin screening by LAL assay. One vial of every batch is also shipped to an independent US-based third-party lab for blinded re-verification. The full COA — including the chromatogram, mass spec trace, and third-party report — is bundled with your order as a downloadable PDF.

How does Vesta ship to the United States?

+

All orders ship cold-chain via DHL Express from our Guangzhou facility. Cold-pack is validated to hold under 8°C for 96 hours. Customs duties are prepaid by us — no surprise charges on delivery. Estimated transit time is 7-10 business days door to door. Tracking number is emailed when the shipment is scanned by DHL.

What payment methods are accepted?

+

ACH bank transfer (2% off, recommended), USDC / BTC / ETH crypto (5% off), Zelle, CashApp, Venmo, or wire transfer for institutional orders. We do not accept credit cards because card processors prohibit research-peptide merchants in their terms of service. Full payment-method details are on the shipping & payment page.

What is the plasma half-life of Semaglutide?

+

Semaglutide has a reported plasma half-life of ~1 week in human pharmacokinetic studies, supporting weekly dosing schedules in research protocols. The extended half-life comes from albumin binding via the molecule's fatty acid side chain modification.

How does Semaglutide compare to other GLP-1 family analogs?

+

Semaglutide is one of several GLP-1 receptor agonists in active research. Vesta also stocks tirzepatide (dual GLP-1 + GIP) and retatrutide (triple GLP-1 + GIP + glucagon) for comparative studies. All ship from the same QC pipeline so cross-compound comparisons don't carry batch-to-batch confounders.
