Description

Semaglutide is a 31-amino-acid acylated GLP-1 receptor agonist research peptide. LiveWell supplies it as a lyophilized vial in 5mg and 10mg sizes, strictly for in-vitro laboratory research use only — it is not for human or animal consumption.

Structure

Semaglutide carries a C18 fatty-acid chain attached via a linker, a modification examined in the literature for its effect on albumin binding and molecular stability. This acylation is the property most often studied in comparative work against non-acylated GLP-1 analogs.

Chemical information

Sequence length: 31 amino acids
Class: GLP-1 receptor agonist (acylated)
Modification: C18 fatty-acid chain via linker
Available sizes: 5mg, 10mg
Half-life: ~7 days reported in published literature

Studied in

GLP-1 receptor (GLP-1R) binding and signalling research
Receptor-selectivity comparisons with dual and triple agonist research compounds
Acylated vs non-acylated analog stability research
Cell-model assay development and structure-function analysis

Storage & handling

Store the lyophilized vial refrigerated at 2–8°C, protected from light and heat
Reconstitute with bacteriostatic water; reconstituted material has a shorter storage window
Follow your laboratory’s standard peptide handling protocol and institutional guidelines

Frequently Asked Questions

What is Semaglutide?

Semaglutide is a 31-amino-acid acylated GLP-1 receptor agonist research peptide, studied for its role in GLP-1 receptor pathway signalling. Supplied as a lyophilized vial strictly for laboratory research use only.

How does Semaglutide differ from Tirzepatide?

Semaglutide is a single GLP-1 receptor agonist. Tirzepatide is a dual GIP/GLP-1 receptor agonist. The additional GIP receptor activity is the primary structural and mechanistic distinction studied in comparative research.

What is the fatty-acid modification for?

The C18 fatty-acid chain, attached via a linker, is studied for its effect on albumin binding and molecular stability compared with non-acylated GLP-1 analogs.

What purity is LiveWell Semaglutide, and is a COA included?

Every batch is third-party tested at ≥99% purity by HPLC, with mass spectrometry identity confirmation and LAL endotoxin testing. A full Certificate of Analysis is included and published on our COA page.

How should Semaglutide be stored and reconstituted?

Store refrigerated at 2–8°C, protected from light and heat. Reconstitute with bacteriostatic water; reconstituted material has a considerably shorter storage window.

Is Semaglutide a drug or supplement?

No. Semaglutide research peptide is a research compound sold strictly for laboratory use only. It is not a drug, dietary supplement, food or cosmetic, and it is not intended for human or animal consumption.
