Semaglutide (GLP-1 receptor agonist)
Semaglutide is a 31-amino-acid GLP-1 analog structurally modified at position 8 (Aib substitution) to resist DPP-4 degradation, with a C18 fatty diacid chain conjugated via a spacer at Lys26 that promotes albumin binding. These modifications extend its half-life substantially relative to native GLP-1, which has a circulating half-life measured in minutes. It is among the most heavily published peptides in modern metabolic research.
Research applications
- Incretin receptor signaling and β-cell response studies
- Gastric emptying and satiety-pathway research in rodent models
- Comparative pharmacokinetics against dual and triple agonists
- Receptor binding affinity and selectivity assays
Storage
Store lyophilized powder at -20°C protected from light. Reconstituted solution is stable at 2-8°C for up to 30 days.
Reconstitution
Reconstitute with bacteriostatic water directed slowly down the vial wall. Do not shake — agitation causes peptide denaturation. Swirl gently until fully dissolved.

Semaglutide questions
- Where can I buy semaglutide for research?
- Lyra Vital sells semaglutide as a lyophilized research peptide in 5 mg, 10 mg and 20 mg single vials, shipped from Orlando, Florida. Every lot's Janoshik Analytical certificate is published with its verification key, so the result can be confirmed with the laboratory directly. For research use only; not for human consumption.
- Is research-grade semaglutide an FDA-approved product?
- No. Semaglutide is the active ingredient in prescription drugs approved by the FDA, which are manufactured and released under those approvals. Research-grade material sold here is a laboratory chemical, not an approved drug product, and is not for human or veterinary use.
- Which certificate covers the vial size I order?
- Each size has its own lot and certificate, listed size by size on this page. The batch code printed on your vial returns its certificate in the lookup at lyravital.com/verify. The laboratory certifies a lot, not a fill weight, so the measured content on a report can differ from the label size.
- How do I check a semaglutide certificate myself?
- Take the task number and unique key from the certificate and enter them at janoshik.com/verification. The laboratory returns its own copy of the report. Lyra Vital neither issues nor hosts that result, so the check does not depend on us.
