SEMA — Semaglutide (Lyophilized Research Peptide, 5mg–15mg)
SEMA (Semaglutide) is a GLP-1 receptor agonist peptide widely studied in metabolic and endocrinology research. It is primarily investigated for its role in glucose-dependent insulin secretion, appetite signaling pathways, and energy balance regulation.
In research models, Semaglutide is commonly explored for its effects on satiety mechanisms, glycemic control pathways, and metabolic efficiency.

How Semaglutide Compares to Other GLP-1 Research Peptides
Semaglutide is a single GLP-1 receptor agonist — the baseline compound of the incretin research class — compared with tirzepatide (GLP-1/GIP dual agonist) and retatrutide (GLP-1/GIP/glucagon triple agonist).
| Compound | Receptor Targets | Research Class |
|---|---|---|
| Semaglutide (SEMA) | GLP-1 | Single agonist |
| Tirzepatide (TIRZ) | GLP-1 + GIP | Dual agonist |
| Retatrutide (RETA) | GLP-1 + GIP + Glucagon | Triple agonist |

Semaglutide (SEMA) — Frequently Asked Questions
Where can I buy the semaglutide research peptide?
You can buy semaglutide directly from Dr Jays Peptides in 5mg, 10mg, and 15mg lyophilized research vials. Every batch is third-party tested, ships same-day from the US, and includes free bacteriostatic water.
Is SEMA the same as semaglutide?
Yes. SEMA is the research shorthand for semaglutide, a GLP-1 receptor agonist peptide studied in metabolic research models.
Is your semaglutide third-party tested?
Yes — every batch is third-party lab tested for purity and identity before release.
How should semaglutide be stored?
Store lyophilized vials at -20°C. After reconstitution with bacteriostatic water, refrigerate at 2–8°C and use within 30 days.
What is CagriSema?
CagriSema is the studied combination of semaglutide with the amylin analog cagrilintide. We supply it as a Cagrilintide + Semaglutide blend for combination-pathway research.
