Why we built this.
Peptide dosing information is scattered across forums, paywalled journals, and unreliable sources. PepperCalc was built to change that — a single, clean, free reference for researchers who take their work seriously.
PepperCalc combines "peptide" (abbreviated to "pepper" for personality) with "calc" — short for calculator. It's the dose calculator and protocol reference that researchers actually want to use.
20+ peptide protocols including BPC-157, TB-500, Semaglutide, Retatrutide, Tirzepatide, GHK-Cu, MOTS-c, Tesamorelin, and all major research stacks. Every protocol includes dosing ranges, reconstitution instructions, cycle timing, and research notes.
PepperCalc is and will always be free. No paywalls, no subscriptions, no ads. We're supported by our sister brand, White Market Peptides — where researchers can source the compounds they're studying.
PepperCalc is an educational and research reference only. All content is for informational purposes and not medical advice. Nothing on this site should be construed as a recommendation to use any compound. All products referenced are for research use only and have not been evaluated by the FDA.
