## FAQ

### What's the difference between GLP-1, dual, and triple agonist peptides?

GLP-1 single agonists (semaglutide) hit one receptor. Dual agonists (tirzepatide) hit GLP-1 and GIP. Triple agonists (retatrutide) add glucagon receptor activity on top of both.

### Does high market demand affect peptide purity for research use?

Yes. Fast-growing demand draws in more unverified manufacturers, so checking a certificate of analysis matters more, not less, when a compound is trending.

### How should reconstituted GLP-1 class peptides be stored?

Refrigerate at roughly 2 to 8°C, protect from light, and avoid repeated warm-up cycles, which degrade longer, multi-target peptides faster than simpler ones.
