StackTrackr vs Ligand · Peptide Tracker

Keep track of every shot. Log the dose in one tap, know what is left in the vial and when it runs out, and watch estimated levels rise and fall between injections. Then see it on your health charts: every injection overlaid on heart rate, sleep, weight, and recovery, so you can tell whether a protocol is working. StackTrackr is the shot log, dose tracker, and reconstitution calculator built for peptides, testosterone (TRT), anabolic and research compounds, and GLP-1 medications. Retatrutide, BPC-157, TB-500, MOTS-c, Tesamorelin, CJC-1295 + Ipamorelin, GHK-Cu, testosterone cypionate or enanthate, nandrolone, or a complex multi-compound stack: StackTrackr handles every protocol with precision. Many are FDA-approved and clinician-prescribed; others are research compounds. TESTOSTERONE AND TRT Built for weekly, twice-weekly, and every-other-day injection schedules. Log cypionate, enanthate, or propionate doses, rotate injection sites, and see estimated levels from every shot on one chart. Track nandrolone and other compounds alongside testosterone in the same protocol. ESTIMATED ACTIVE LEVELS See how much of each compound is estimated to remain in your system, based on published half-life data and your last 28 days of logged doses. ANALYTICS: YOUR DOSES ON YOUR DATA Connect Apple Health and StackTrackr overlays every dose you log onto your health charts, so injections and trends sit on one timeline. • Dose markers on resting heart rate, HRV, sleep stages, weight, body composition, nutrition, recovery, and mood • After Doses: compare your metrics before and after each dose, compound by compound • 7 metric groups, a dashboard you build yourself, and trends from 30 days out to a full year SHOT LOG AND INJECTION TRACKING One-tap logging with dose amounts, injection sites, timestamps, and notes. Never second-guess when your last shot was or which site you used. VIALS THAT TRACK THEMSELVES Vials deplete automatically as you log, oldest first, so nothing expires unused. See how many doses remain in every vial and the date it runs out, with a low-supply warning before the last dose. RECONSTITUTION CALCULATOR Enter vial amount, bacteriostatic water volume, and target dose to get the exact mL and insulin-unit draw instantly. Supports mcg, mg, and IU conversions. Works with single-compound vials and blend vials with ratio-based dosing, including glow and wolverine blends. LOG FROM ANYWHERE Log a dose in seconds without opening the app, from your Apple Watch, a Home Screen or Lock Screen widget, or Siri. PROTOCOLS, CYCLES, AND STACKS Daily, every other day, twice weekly, weekly, biweekly, monthly, 5-on-2-off, or fully custom cycles. Run multiple protocols at once with color-coded organization and keep an entire stack on one schedule. Per-protocol streaks, with retroactive recovery for a missed dose. 120+ VERIFIED COMPOUNDS A fact-checked database of peptides, hormones, and research compounds with molecular weights, standard reconstitution volumes, typical dosing ranges, and storage guidelines, verified against published sources. BUILT FOR REAL PROTOCOLS • Testosterone replacement therapy and hormone protocols (cypionate, enanthate, propionate, nandrolone) • Peptide stacks for recovery, performance, lean mass, wellness, and anti-aging • GLP-1 weight management protocols, including Retatrutide • Research compound cycles and complex multi-compound stacks STACKTRACKR PRO Unlock unlimited compounds and protocols, custom compound creation, the blend vial calculator, dose-overlay and After Doses analytics, and protocol reminders. Your data syncs securely across devices and your history is there whenever you open the app. No ads. Disclaimer: StackTrackr is for educational and personal tracking purposes only.

Ligand is a fast, private calculator and log for reconstituted peptides — built to show its work, not to tell you what to take. RECONSTITUTION & DOSE MATH YOU CAN CHECK Enter your vial mass, BAC water, and target dose — in mg or mcg, your choice — and Ligand lays out the concentration, the corresponding syringe volume, and the exact syringe units, with every step of the working shown. See the exact result and where it lands on a whole syringe mark. SAVE EVERY CALCULATION Save any calculation as a checkable record: the inputs you entered, the full derivation, and the result, frozen exactly as they were. Reopen it anytime, use it as the start of a new one, or share the whole working as plain text. FREE TO TRY — NO ACCOUNT The calculator, your saved calculations, and your log are free. No sign-up, no account, no paywall before you can check a number. A PRIVATE LOG Track your vials and your own schedule. Your data stays on your device — it's yours. PRO (optional) • Unlimited vials • Export & back up your records — CSV + JSON • Peptide Assistant — brief answers on kinetics and mechanism, with source links Available monthly, yearly, or as a one-time Lifetime purchase. Ligand does the math and keeps your record. It does not provide medical advice, diagnose, or recommend a dose.
