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.

User Reviews

Overall, the app is well designed and easy to use. However, there are two areas that significantly impact usability and should be prioritized for improvement. 1. Database Access Currently, accessing the database takes the user out of the app and into an external browser/page. This creates a fragmented experience, interrupts workflow, and makes the platform feel less integrated. Keeping database access within the app would provide a much smoother user experience and encourage more frequent use of the feature. 2. Backdating Missed Injections The inability to backdate a missed injection entry is a major limitation. In real-world use, users occasionally forget to log a dose at the exact time it was administered. Preventing backdated entries can lead to inaccurate records, incorrect half-life calculations, and reduced confidence in the tracking data. Allowing users to enter a past injection date and time would improve both accuracy and long-term adherence to tracking. Of these two issues, the inability to backdate injections has the greatest impact because it directly affects the accuracy of the data the app is designed to track. For an application focused on medication management, maintaining accurate historical records should be considered a high-priority feature.
