What we do
PeptideDraw provides free reconstitution calculators, dosing references, and a private tracker for people navigating peptides and GLP-1 medications. Our goal is simple: make the math accurate and the context honest.
How the calculators work
Every calculator uses the same transparent formula: concentration = peptide (mg) ÷ BAC water (mL), and units = (dose ÷ concentration) × 100 for a U-100 insulin syringe. There is no hidden adjustment — you can verify the math by hand.
Our sources
Dosing charts for approved medications are based on FDA prescribing information (Mounjaro®, Zepbound®, Wegovy®). Investigational figures for retatrutide reflect published Phase 2 clinical-trial data. Research-peptide ranges are drawn from preclinical literature and clearly labeled as non-medical references.
Our commitment to safety
We never present unapproved peptides as approved medicines, and we always direct dosing decisions back to a licensed clinician. Content is reviewed for accuracy against primary sources and updated as the science moves.
