Mechanism & published research
Selective GLP-1 receptor agonism with a fatty-acid modification conferring a long half-life via albumin binding.
Extensive phase 3 evidence across glycemic and weight endpoints.
Descriptions summarize existing published research and are not claims about outcomes from use. Every citation states its study type and population.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| Tirzepatide | Receptor targets | Tirzepatide adds GIP; semaglutide is GLP-1 only. |
| Cagrilintide | Class | Cagrilintide is an amylin analog, often studied alongside GLP-1 agonists. |
Reconstitution
Concentration math only: add bacteriostatic water to the vial and the resulting concentration is shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 10 mg | 2 mL | 5 mg/mL |
| 20 mg | 2 mL | 10 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 4 weeks |
Reviews
Reviews are collected post-delivery and screened to exclude any human-use or dosing-outcome claims before publication. They speak to product quality, shipping, and COA accuracy.
“Lot matched the hub COA and the endotoxin figure was printed, not just implied. Rare transparency.”
“Had a question about the storage window and got a clear answer that matched the product page. Consistent.”
“Free shipping kicked in over the threshold and it arrived tracked in three days. No surprises at checkout.”
