Pepti is available as a one-time purchase on the App Store and Google Play. We believe in owning your tools, so there are no hidden monthly subscriptions or premium unlock fees. Buy it once, use it forever.
Pepti supports GLP-1 agonists, dual-agonists (GLP-1/GIP), and triple-agonists (GLP-1/GIP/GCG). We have built-in pharmacokinetic profiles for Tirzepatide (Mounjaro, Zepbound), Semaglutide (Ozempic, Wegovy), Dulaglutide (Trulicity), Retatrutide, and the ability to add custom medications.
Different medications stay in your body for different amounts of time (this is called "half-life"). Pepti uses a mathematical model based on the specific half-life of your medication (e.g., ~5 days for Tirzepatide) to estimate how much medication is still active in your system from previous doses.
