Halflife - Peptide & GLP-1 Log

If tirzepatide, peptides, TRT, insulin, nootropics, and longevity compounds are part of the same protocol, fragmentation becomes the limiting factor. Halflife unifies multi-compound protocols into a single system for dosing, pharmacokinetics, adherence, inventory, and real-world performance tracking. Core System Tracks complete protocol stacks across GLP-1 medications, recovery peptides, growth hormone secretagogues, testosterone replacement, insulin, nootropics, sexual health agents, and longevity compounds in one environment. Every compound is logged within a unified timeline with dose history, vial stock, and schedule position. Concentration Curves Uses published pharmacokinetic data from FDA labels and peer-reviewed research to model active compound levels over time. Each compound is displayed as a live curve showing time to peak, current activity as a percentage of peak, and clearance trajectory. Biological effect windows model downstream activity for short half-life peptides. Today Screen Central execution layer for all protocols. Shows due doses, week progression, remaining vial inventory, and one-tap logging. Injection site rotation tracked automatically. Integrated syringe calculator converts vial concentration and target dose into exact draw volume. Protocol Tools Synergy Matrix, Reconstitution calculator, Unit converter, Vial runway calculator, Adherence circle. Compound Database Medically cited library covering tirzepatide, semaglutide, BPC-157, TB-500, CJC-1295, ipamorelin, testosterone esters, insulin, nootropics, and longevity compounds. Biometric Intelligence Apple Health integration connects sleep, HRV, heart rate, and weight trends with dosing history. Community System Pods, Challenges, Daily polls, Community discovery. Data Model All data stored locally on device. Nothing transmitted externally. 45 substances across GLP-1s, peptides, GH secretagogues, TRT, insulin, nootropics, sexual health, and longevity stacks. Free tier: two compounds, full logging, weight tracking, 4 free tools, Adherence Calculator, Community Access. Advanced unlocks unlimited protocols and full analytics.
