Buy Semaglutide Research Compound.
Semaglutide is a GLP-1 receptor agonist that has become one of the most researched peptides in metabolic and endocrine research. This guide covers sourcing semaglutide for research — specifications, quality evaluation, COA requirements, and storage protocols.
What is semaglutide?
Semaglutide is a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist originally developed for type 2 diabetes management. It is a modified GLP-1 analog with a C17 fatty acid side chain that enables albumin binding and extended half-life. Research into semaglutide has expanded significantly to include studies on appetite regulation, weight management, cardiovascular outcomes, and neuroprotective effects.
Semaglutide supplied by B&H Bio is a research compound for laboratory and preclinical evaluation. It is not for human consumption.

| Sequence | GLP-1(7-37) analog with Aib⁸ and C17 fatty acid side chain | Confirms structural modification |
| Appearance | White to off-white powder | Visual quality indicator |
How to evaluate semaglutide quality
- HPLC purity verificationThe COA must show HPLC chromatographic data with a quantified purity percentage. "Passes" without a number is insufficient.
- Mass spectrometry confirmationMS data confirms the molecular weight matches the expected 4,113.58 g/mol, verifying the correct compound was synthesized.
- Amino acid analysisConfirms the peptide sequence and modifications are correct, including the Aib substitution and fatty acid conjugation.
- Endotoxin testingFor in vitro and in vivo research, endotoxin levels must be reported on the COA.
COA requirements for semaglutide
A research-grade semaglutide COA should document:
- Identity testingHPLC retention time comparison and/or mass spectrometry molecular weight confirmation.
- Purity quantificationNumerical HPLC purity (≥99%), not a pass/fail statement.
- Endotoxin levelMeasured by LAL assay with the specific value reported.
- Lot number and manufacture dateFor traceability and shelf-life calculation.
- Third-party verificationIndependent lab (e.g., Eurofins) testing provides the highest confidence level.
Semaglutide storage and handling
-20°C storage
Store lyophilized semaglutide at -20°C protected from light. Stable for 24+ months under proper conditions.
2-8°C storage
After reconstitution with bacteriostatic water, store at 2-8°C. Use within the supplier-recommended window. Avoid freeze-thaw.
Protect from light
Semaglutide is light-sensitive. Store in amber vials or wrapped in foil. Minimize exposure during handling.
