The Android Peptide Calculator
That Actually Does the Math
Most peptide calculators on Android give you a number and call it done. Protocol's reconstitution calculator has a concentration slider — adjust BAC water volume in real time and see draw units, concentration, and doses per vial update instantly. Custom draw amount. Syringe visualization. The math, done properly.
Also available free at reconstitution.health
Full Feature Parity with iOS
Everything on iOS is on Android. No features cut. No compromises.
The Most Private Android Peptide Tracker

The Android App Built for Serious Protocol Runners
Protocol is the only Android peptide tracker that treats your protocol as a system — compounds, supplements, and habits tracked together in one unified protocol. Your injury recovery stack (BPC-157, TB-500, collagen supplement, mobility habit) tracked as one unit with one adherence score. No other Android peptide tracker does this.
For GLP-1 users on Android — semaglutide, tirzepatide, retatrutide — Protocol tracks your injection site rotation on a 3D body map, your titration schedule, and your dose history. The body map shows front and back simultaneously with color-coded rotation history. Proper site rotation prevents lipodystrophy and maintains absorption consistency.
For TRT users on Android — testosterone, HCG, anastrozole — Protocol tracks your full protocol alongside bloodwork panels. Log testosterone, estradiol, SHBG, LH, FSH, and 80+ additional biomarkers. See how your labs trend over time against your protocol timeline.
For the biohacker running complex stacks — Protocol's Stack Score rates your entire protocol across six dimensions and visualizes it as a radar chart. The Interaction Checker flags how your compounds work together — synergy, redundancy, timing, and caution flags for 30 most common pairs. The AI Research Assistant knows your actual stack and gives you specific answers, not generic responses.
Free to download on Google Play. 14 days of Pro unlocked at install. Everything on your device.
