iPhone

The reconstitution calculator that shows its work. Free forever, no account, and nothing you enter ever leaves your iPhone. Peptionary does the reconstitution math, then explains it — so you understand the number instead of trusting it blindly. Most calculators hand you a result. Peptionary shows you how it got there: the concentration, the volume, and the reasoning behind each step, in plain language. There is a to-scale syringe view so you can see the measurement, not just read it. THE CALCULATOR IS FREE. FOREVER. No account. No sign-up. No trial timer. The reconstitution calculator, the step-by-step explanation, and the concentration and units guide are free and always will be. WHAT'S FREE • Reconstitution calculator with to-scale syringe view • Step-by-step explanation of every calculation • Concentration and units guide • Full offline use — no account, ever PEPTIONARY PRO — OPTIONAL SUBSCRIPTION Pro unlocks the reference library and personal organization tools: • 113 compound profiles with mechanism, human and animal evidence, regulatory status, risks, and citations to primary literature • Evidence grades assigned against a published rubric • Recorded entry tracking and history • Vial inventory with balances and batches • Potency clock — elapsed time since a vial was mixed • Cost per dose, from your own vial cost • Export a copy of your own records HOW WE GRADE EVIDENCE We publish our entire grading rubric at peptionaryhub.com/methodology — the five tiers, the rules for assigning them, and the claims we deliberately refuse to make. We grade specific uses rather than whole compounds, because a compound can have real human evidence for one purpose and nothing but animal studies for another. Our content is editorially reviewed. It is not clinically reviewed, and we say so on every profile rather than implying an authority we haven't earned. We take no money from peptide vendors, suppliers, or compounding pharmacies. No affiliate links, no paid placement, and no grade has ever been influenced by a commercial relationship. PRIVATE BY DESIGN There are no accounts, no analytics, no advertising, and no third-party tracking software of any kind. Everything you enter — calculations, entries, inventory, notes — stays on your iPhone. We have no servers holding your information and no way to see it. That also means we cannot recover it, so Pro subscribers can export a backup at any time. IMPORTANT Peptionary is an educational reference and personal organization tool. It does not provide medical advice, diagnosis, treatment, or dosing recommendations, and it is not a substitute for a qualified healthcare professional. The calculator works only from values you enter yourself and never suggests what those values should be. Always consult a licensed clinician about anything you intend to use, and follow the laws that apply where you live. Peptionary is intended for adults 18 and over. SUBSCRIPTION DETAILS Peptionary Pro is available monthly or annually with a 7-day free trial. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel in your device Settings under your Apple Account.
