About

Peptide Calculations does two things. It turns a vial, a volume of water and a dose into the units to draw on an insulin syringe, with the arithmetic shown. And it collects dosage charts for the peptides people actually use, from BPC-157 to retatrutide, with the source for every range.

Where the numbers come from

Calculator results are plain division; the formulas are on one page. Dose ranges come from three kinds of source and each chart says which: an FDA drug label, a published human trial, or what people commonly report for peptides that have never been through a human trial. We do not dress up the third kind as the first.

What we do not do

We sell nothing, run no ads, and have no affiliation with any peptide brand: no affiliate links, no referral codes, no sponsorships. Where a page says where to buy, it names the brands we recommend on the merits. We do not give medical advice; a dosage chart is a summary of what is published, not a prescription. Talk to a clinician, start low, and read the source.

Who runs it

An independent editorial team; see the disclosure. No bylines, because none of this is opinion.
