How these pages are built

Sourced from PubMed

Every reference is checked against the PubMed record and linked by PMID and DOI. A citation that cannot be verified is marked under review rather than linked to the wrong paper.

Dosing as published

Protocol ranges come from the source documents. Syringe units in every vial table are recomputed from the vial concentration so the arithmetic on the page is right.

Regulatory status stated

FDA status, WADA status, contraindications and monitoring requirements are listed on every page, in the same place, so nothing important is buried.

Not medical advice

These pages are educational. Peptide therapies belong under the supervision of a licensed healthcare provider who can assess individual needs and determine appropriate dosing.
