Compare peptides
Neutral side-by-side comparisons of popular peptides — regulatory status, evidence tier, route, dosing frequency and reference ranges for each. Reference only — not medical advice or a recommendation to use any of them.

Each comparison lays out both peptides side by side, with the reference facts for each. More comparisons are on the way.

An approved GLP-1 against the investigational triple agonist — side-by-side reference data.
Two growth-hormone secretagogues compared — status, route and reference dosing.
Two research repair peptides side by side — regulatory status and reference data.
What these comparisons do (and don’t)
Each page collects the labeled or published reference facts for two peptides and puts them next to each other — regulatory status, evidence tier, route and dosing frequency. They do not rank the peptides, recommend one over the other, or tell you what to take. They reflect the limited information available and are reference only; decisions belong with a qualified professional.
Reference and arithmetic only. Not medical advice; verify with a clinician, product label, pharmacist, or approved research protocol.
Frequently asked questions
What do these comparison pages show?
Each lays out two peptides side by side — regulatory status, evidence tier, route, dosing frequency and reference ranges — drawn from labels and published data. Reference only, not medical advice.
Do they recommend one peptide over the other?
No. They are neutral references that do not assess which peptide is better, safer, or more suitable for anyone. That decision belongs with a qualified professional.
Which comparisons are covered?
GLP-1 pairs (tirzepatide, semaglutide, retatrutide) and research-peptide pairs (CJC-1295 + ipamorelin, BPC-157 + TB-500). More are being added.
Can I calculate dosing from a comparison?
Some comparison pages embed a calculator, and each peptide has its own reconstitution calculator linked from the page. The math is arithmetic only.
