Frequently Asked Questions
What is Semaglutide peptide?
Semaglutide is a synthetic GLP-1 (glucagon-like peptide-1) receptor agonist, an FDA-approved active pharmaceutical ingredient studied extensively in metabolic and glycaemic research. Peptalix Labs supplies Semaglutide 20mg at 99.07% purity, verified via a full QC panel by ILS Laboratories.
What purity is Peptalix Labs Semaglutide 20mg?
Independently tested at 99.07% purity by ILS Laboratories (San Diego, ISO/IEC 17025 accredited) via a full QC panel including heavy metals and sterility testing. Net peptide content 20.52mg per vial, Lot 125-01-SM, COA #COA-2026-3BGEA5.
Is Semaglutide FDA-approved?
Yes. Semaglutide is an FDA-approved active pharmaceutical ingredient (marketed under brand names for clinical use). Peptalix Labs supplies research-grade Semaglutide strictly for in-vitro laboratory research, not for clinical or human use.
Which lab tested this product, and is the COA verifiable?
ILS Laboratories, an ISO/IEC 17025 accredited facility in San Diego, CA. The COA can be independently verified at portal.ils-lab.com using Access Code 3UUYKBTX.
Does this COA include sterility and heavy metals testing?
Yes. The full QC panel includes heavy metals analysis (arsenic, cadmium, chromium, mercury, lead — all Not Detected), sterility testing via PCR (No Growth), and a negative fentanyl screen.
How is Semaglutide peptide stored?
Supplied as lyophilised powder. Store the sealed vial at -20C prior to reconstitution. Once reconstituted with bacteriostatic water, store at 2-8C and use within 28 days.
How do I reconstitute Semaglutide 20mg?
Draw the desired volume of sterile bacteriostatic water into a fresh syringe and inject slowly down the inner wall of the vial. Gently swirl until fully dissolved. Never shake.
What research has been published on Semaglutide?
Semaglutide has an extensive peer-reviewed literature base, including cardiovascular outcomes research and studies on GLP-1 receptor-mediated glycaemic and appetite-regulation pathways.
Can I buy Semaglutide peptide online in the USA?
