GLP-1 Receptor Agonist (long-acting acylated analogue)
C187H291N45O59
4,113.58 g/mol
Approximately 1 week (168 hours)
Semaglutide is an acylated GLP-1 analogue with 94% homology to native GLP-1. It binds to the GLP-1 receptor, stimulating insulin secretion, suppressing glucagon, slowing gastric emptying, and reducing appetite through hypothalamic signalling. The C-18 fatty acid chain enables albumin binding for extended duration.
STEP 1 demonstrated 14.9% mean body weight reduction vs 2.4% with placebo over 68 weeks in adults with obesity.
20% reduction in major adverse cardiovascular events (MACE) in people with overweight/obesity and established cardiovascular disease.
Comprehensive trial program demonstrating superior glycemic control and weight reduction versus comparators across multiple patient populations.
“Access to high-purity semaglutide for our incretin research is invaluable. Peptides Pharma's quality matches what we need for publishable data.”
Dr. J. Holst
Incretin Biology Lab, Copenhagen
“Our internal HPLC confirmed >99.3% purity. The lyophilized format is perfect for our dose-titration metabolic studies.”
Dr. A. Ferrannini
Metabolic Research, Pisa
“Received with cold-chain packaging within 48 hours. Reconstituted cleanly. Our weight management research program relies on this supplier.”
Dr. W. Cefalu
Obesity Research, New Orleans
“Finally a European source for properly formulated research-grade semaglutide in lyophilized vials. Purity verified via HPLC at 98.7%, and delivery to the Netherlands was just four days. Excellent COA documentation.”
Dr. Sophie K.
Amsterdam, Netherlands
“The GLP-1 agonist formulation is spot-on. We've run three independent assays and every result aligns with the COA. Would appreciate more vial size options for different research protocols, but the current 5mg offering is excellent quality.”
Andrew B.
Cardiff, UK
“Quality is excellent and the lyophilized powder reconstitutes cleanly. Would love to see additional vial sizes in the future, but the current offering serves our metabolic research needs well.”
Laura G.
Newcastle, UK
“We've ordered multiple batches for our metabolic research programme. Every vial has been consistent — proper lyophilization, clean reconstitution, and purity matching the COA. Peptides Pharma is our go-to supplier.”
Dr. R. Novak
Prague, Czech Republic
Semaglutide is a pure GLP-1 receptor agonist, while tirzepatide is a dual GIP/GLP-1 agonist. Head-to-head trials (SURPASS-2) showed tirzepatide achieved greater weight loss, though both are highly effective. The choice depends on the specific research question.
