Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
Semaglutide is a synthetic analog of the human glucagon-like peptide-1 (GLP-1) hormone, primarily studied in research for its effects on glucose metabolism and appetite regulation. This peptide is commonly investigated in laboratory settings for its potential in metabolic and obesity-related research models.
Evidence brief

- What the research says about semaglutide Strong evidence
Semaglutide is a GLP-1 receptor agonist studied in phase 3 randomized controlled trials and summarized in a meta-analysis for weight management and type 2 diabetes.

- Semaglutide 2·4 mg once a week in adults with overweight or obesity, and type 2 diabetes (STEP 2): a randomised, double-blind, double-dummy, placebo-controlled, phase 3 trial PubMed ↗
This trial assessed the efficacy and safety of the GLP-1 analogue once a week subcutaneous semaglutide 2.4 mg versus semaglutide 1.0 mg (the dose approved for diabetes treatment) and placebo for weight management in adults with overweight…
- Efficacy and Safety of Semaglutide for Weight Loss in Obesity Without Diabetes: A Systematic Review and Meta-Analysis PubMed ↗
The weight loss benefit of semaglutide in patients with diabetes is well-documented, but its clinical utility in treating obesity among patients without diabetes is less described. We therefore assessed the efficacy and safety of…
- Safety of Semaglutide PubMed ↗
The glucagon-like peptide-1 receptor agonist (GLP-1RA) semaglutide is the most recently approved agent of this drug class, and the only GLP-1RA currently available as both subcutaneous and oral formulation. While GLP-1RAs effectively…

▸ Why compare $/mg for Semaglutide?
Per-mg prices for semaglutide vary significantly across vendors due to differences in synthesis purity, scale, and sourcing of raw materials. Comparing prices helps researchers identify cost-effective suppliers while maintaining quality standards for reproducible experimental results.
▸ Reading the COA
A third-party Certificate of Analysis (COA) for semaglutide should confirm identity via mass spectrometry (e.g., ESI-MS) and purity ≥98% by HPLC. Common issues include under-filling (e.g., actual content below labeled mg/vial) and adulteration with truncated or oxidized peptide fragments.
▸ FAQ
How should I store semaglutide for research use?
Lyophilized semaglutide should be stored at -20°C or below, protected from light and moisture. Reconstituted solutions are typically stable for short periods at 2-8°C, but researchers should verify stability data from the supplier.
What is a Certificate of Analysis (COA) and why is it important?
A COA is a document from the supplier or third-party lab detailing the compound’s identity, purity, and batch-specific test results. It is critical for verifying that the peptide meets research-grade specifications and is free from contaminants.
Why do prices for semaglutide differ so much between vendors?
Price differences arise from factors like synthesis scale, purification methods (e.g., HPLC vs. flash chromatography), and vendor overhead. Lower prices may indicate lower purity or under-filling, so researchers should always check COAs before purchase.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
