Peptides

Citable numbers on GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide, dulaglutide, exenatide) — market size, prescription volume, user demographics, clinical outcomes, pricing, insurance, side effects, and regulatory actions. Every stat is sourced. Use the anchor links to cite specific numbers. Last updated: 2026-04-27.

A guided 5-question wizard that maps you to the FDA-approved peptide options most likely to match your situation. Restricted to FDA-approved peptides — every answer ends with “consult your prescriber.” This is not medical advice and does not replace a clinician. The recommendations are conversation starters for your prescriber, not prescriptions. Final decisions belong to

If you have been choosing between marine and bovine collagen and feeling like the difference is either obvious or impossible, the short answer is: for skin outcomes, both work, but the research volume heavily favors bovine peptides, and marine collagen trials are still catching up. The real difference comes down to source, amino-acid profile, molecular
