An accurate, fast, free peptide calculator.
PeptideDose exists because the peptide calculators that already live on the web are generally either ad-clogged afterthoughts hosted by clinics or single-purpose mobile apps that hide basic functionality behind a paywall. Researchers and laboratory professionals deserve better. The site is an educational reference for in vitro research-use peptide reference data; products covered are research-only and the site does not address human use, prescribed therapy, or patient self-administration.
Behind PeptideDose
I'm Stephen Pickering — I built PeptideDose because the calculator I wanted didn't exist. The peptide tools already on the web are either ad-clogged afterthoughts or paywall basic features that should be free. I'm not a clinician. The site is a working tool for researchers and laboratory professionals working with research-only peptide reference data — nothing more, nothing less.
What we do
We provide a fast, free reconstitution and dosage calculator that works for the peptides people actually use — semaglutide, tirzepatide, retatrutide, BPC-157, TB-500, GHK-Cu, CJC-1295, and roughly fifty others — alongside educational reference pages that show the math, cite their sources, and link to authoritative literature.
Editorial independence
PeptideDose is an independent project. We are not a clinic, a pharmacy, or a peptide vendor. We have no commercial relationship with any specific peptide manufacturer that would influence the dose ranges we display. Every quantitative figure on the site cites a primary source — typically an FDA-approved product label, a PubMed-indexed paper, or a registered ClinicalTrials.gov entry.
How we're funded
The site is supported by advertising (Google AdSense) and by clearly disclosed affiliate links to research-vendor sourcing on selected peptide pages. Funding does not influence which peptides we cover, the dose ranges we cite, or our editorial framing.
