Research reference. This page summarises practitioner consensus and published evidence. It is not medical advice. Consult a prescriber. Verify third-party testing on any peptide you reconstitute.

What this site is for prescribers

The Peptide Index is a research reference, not a clinic, not a compounding pharmacy, not a sales channel. The site is built so the prescriber reader can pull up a protocol, a dose, a plausibility grade, and the source citation in under 30 seconds.

Every dose in the field reference, the FAQ, and the calculator comes from a published source or a named practitioner appearance (Koniver, Gillett, Galpin, Attia, Huberman). Where the human trial data is thin, the entry says so. Where the data is well-established, the entry says so. The reader can audit every claim against the cited source.

How the calculator handles edge cases

The calculator returns a colour-coded safety band for every custom dose, not just the suggested range. Ipamorelin caps single doses at 100 micrograms per Koniver's published rule. PT-141 flags the nausea risk above 1 milligram. Hexarelin flags receptor desensitisation. Thymosin alpha-1 drops the weight-anchored dose for anyone under 50 kilograms.

The math runs entirely in the browser. No data leaves the page. The calculator is safe to use in front of a patient on a clinic tablet.

Submit a correction or a source

If you spot a dose that does not match your clinical experience, or a source that needs to be added, the editorial team will respond. Email corrections@thepeptideindex.info with the citation, the discrepancy, and the proposed update. Corrections are reviewed weekly and rolled into the field reference and the calculator data file together, so the two never drift.
