- The following comparison synthesizes mechanism, research application, and procurement specifications for the leading compounds dominating peptide sales in September 2026.
- Tirzepatide
- Dual GIP/GLP-1 receptor agonist
- Metabolic regulation, weight loss models
- 5–15mg weekly subcutaneous
- 2–8°C refrigerated after reconstitution
- Superior metabolic outcomes vs single-target compounds; dual agonism drives 42% YoY growth
- Semaglutide
- GLP-1 receptor agonist
- Cardiovascular outcomes, NAFLD research
- 1–2.4mg weekly subcutaneous
- Established safety profile with 8,400+ publications; remains reference standard despite newer alternatives
