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

- Cost-per-month by region. Compare what you'd pay for the same dose schedule across Bangkok, Singapore, Bali, Dubai, London, the US.
- Stack interaction checker. Cross-reference half-lives + receptor overlap when running multi-peptide protocols.
- Microdose taper planner. Step-down schedules from your current dose with weight-regain risk projections.
Tools ship when they're correct, not when the calendar says so.
