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 patients deserve better.

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.

Who we are

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.

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.
