Semaglutide

In brief: Semaglutide (INN: semaglutide) on Longeva is a lyophilized powder in a glass vial, research use only (RUO), supplied in 5 mg, 20 mg, and 50 mg vials. On this page you can pick a fill size and check availability and price. The label carries the substance and fill size; batch quality is confirmed by an independent COA per LOT.

Batch verification by COA

1. Find the LOT number on the vial and the outer packaging.
2. Open the PDF for this substance in the COA archive.
3. Check the substance name, the methods (HPLC, identity), and the units of the results.
4. Record the date of receipt and the link to the PDF in your batch log.

Batches are accompanied by a COA from an independent third-party laboratory — check your LOT in the open archive; the report confirms the analytics at the time of testing, not the medical status of the material.

What we sell: a research RUO sample of the semaglutide molecule, a modified GLP-1 analogue and long-acting agonist of the glucagon-like peptide-1 receptor. Clinical programmes studied it in controlled protocols, among them STEP for body weight control and SUSTAIN for glycaemic control in type 2 diabetes. This is mechanistic context for the class, not a promise of an effect from an RUO vial and not an instruction for human use.

Ozempic, Wegovy, Rybelsus — and why this is not the same thing

This is not Ozempic, not Wegovy, and not Rybelsus. Those names are trademarks of finished, registered medicines containing semaglutide in different forms (injectables and an oral tablet); they carry medical labelling and belong to a different product class than an RUO lyophilizate. Longeva does not manufacture, sell, or represent these brands. Each name has its own write-up on how that brand differs from the molecule we supply.

Documentation and storage

Storage conditions per your lab's SOP, the specification, and other batch-level details are covered on the documentation page — that's where the current numbers live, along with what they mean for your protocol; record transport and post-receipt storage conditions in your internal batch log.

Comparisons and further reading

For a structural comparison, see tirzepatide (Tirzepatide); among the neighbouring samples there is also liraglutide (Liraglutide), sold under the Saxenda brand — the difference is covered in Saxenda ↔ liraglutide, and the oral Rybelsus line versus the RUO lyophilizate is covered in Rybelsus vs RUO. The rest of the class is in the GLP-1 agonist category.

The full description of the class — receptor, mechanism, weekly profile — is in the wiki reference for the molecule: it describes the molecule as a class, not a specific vial; fill size, availability, and RUO status are covered by this product card, and what is actually in your LOT is shown only by the COA. Before formulating a protocol, record your research aim, model, reference control, and acceptance criterion — that's the basis for comparing against your batch's COA data.
