Semaglutide at a glance

Semaglutide is an engineered version of the gut hormone glucagon-like peptide-1, keeping roughly 94 percent of the native sequence. An aminoisobutyric acid near the N-terminus blocks cleavage by the enzyme DPP-4, and a lysine carries a linker and C18 fatty diacid that attaches reversibly to serum albumin. Those changes turn a hormone that lasts minutes into a long-lived molecule, with the formula C₁₈₇H₂₉₁N₄₅O₅₉ and a molecular weight of 4113.6 g/mol.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

At the GLP-1 receptor, a class B G-protein-coupled receptor, semaglutide triggers cAMP signaling in pancreatic beta cells, which raises insulin output only when glucose is elevated. Alpha-cell glucagon release falls in parallel. Beyond the pancreas, receptors in the hypothalamus and hindbrain are thought to mediate the reduced food intake seen in studies, and slower stomach emptying contributes early on. Researchers are also examining receptor populations in blood vessels, kidney and immune cells, though how directly semaglutide acts at those sites is still being worked out.

Research and regulatory status

Few peptides have a larger human dataset. Semaglutide is approved as a prescription medicine for type 2 diabetes and for chronic weight management, in both injectable and oral forms, and large outcome trials have examined cardiovascular events and kidney disease. Current investigation includes fatty liver disease, heart failure and neurodegeneration, with some of those programs reporting mixed or negative results. Research-grade material is not the approved product and carries none of its regulatory standing.

Checking the lab data

For a peptide of this size, electrospray mass spectrometry should show a deconvoluted mass consistent with 4113.6 g/mol. HPLC purity needs a full chromatogram, since impurities from incomplete side-chain attachment or truncated sequences can elute close to the main peak. Peptide content per vial, water content and counter-ion are useful extras. The cake should be white and evenly formed. Batch-matched third-party testing is the standard to look for.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 30 mg vial dissolved in 2 mL gives 15 mg/mL, or 30 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

Why is semaglutide's molecular weight so much higher than native GLP-1?

Much of the extra mass comes from the lipid side chain and its linker, which add a sizeable non-amino-acid portion to the peptide backbone. That modification is what allows albumin binding, so a mass result near 4113.6 g/mol helps confirm the side chain is present and intact rather than missing or truncated.

Is semaglutide being studied outside diabetes and obesity?

Yes. Published and ongoing programs look at cardiovascular outcomes, chronic kidney disease, fatty liver disease and heart failure, and exploratory work has examined addiction and neurodegenerative conditions. Results across these areas vary in strength, and several remain early, unresolved or negative.

How much Semaglutide is in this listing?

10 vials of 30mg each — 300 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does TFC Peptides get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
