Free Panya calculators.
Practical math for the things people actually do with peptides and GLP-1s. No login, no paywall, no email capture. The deterministic answers stay accurate as long as the inputs do.
Not medical advice. These are calculators, not protocols. The decision about what dose is right for you is between you and a clinician.
Vial size + bacteriostatic water + dose → concentration, syringe units, doses per vial, cost per dose.
Covers: BPC-157, TB-500, GHK-Cu, MOTS-c, sermorelin, ipamorelin, CJC-1295, AOD-9604, HGH (somatropin)
Pen size + per-injection dose + frequency + start date → weeks of supply, refill-by date, cost per month.
Covers: Mounjaro KwikPen (all strengths), Zepbound autoinjector, Wegovy single-use, Ozempic multi-dose
12-week titration schedule and monthly cost projection across regions.
Covers: Mounjaro, Zepbound, compounded tirzepatide
Pick a compound; see cheapest legitimate route per region with risk and supply context. 17 regions for tirzepatide, 13 for semaglutide.
Covers: Mounjaro, Zepbound, Wegovy, Ozempic, Rybelsus, compounded
Pick your region and compound. See where you land in the global price ranking and how much you'd save sourcing from elsewhere. Shareable URL with social preview.
Covers: Tirzepatide (Mounjaro, Zepbound), Semaglutide (Wegovy, Ozempic, Rybelsus)
