1. Peptide Tracker: Cycle
Best for: being your all-in-one peptide protocol copilot, turning scattered notes and messy spreadsheets into clean, scheduled logging.
Peptide Tracker: Cycle lets you build a cycle in seconds, set dose times, and get a push notification when it’s time to inject. No more hunting through old texts to remember when you last pinned. The interface is refreshingly simple: pick a peptide from the built-in library, set your schedule, and tap “Injected” when you dose. From there, it counts down to your next injection and keeps your full history easy to scan.
The standout feature is automatic dose logging with syringe volume calculations tailored to your specific protocol. When you enter your vial strength and desired dose, the app converts it into insulin syringe units, giving you exactly the number you draw. You can also set up titration ladders, track supply with use‑by alerts, and log injection sites and notes per dose. It’s iOS only, and it’s our top pick for staying consistent without overcomplicating things.
- Smart reminders with a countdown timer so you never miss a dose
- Built-in library of 30+ peptides (GLP-1s, BPC-157, TB-500, testosterone, HCG, and more), plus custom entries
- Reconstitution calculator that gives you units to draw
- Titration ladder builder with auto step-up alerts
- Supply tracking that warns when it’s time to reorder
- One-tap logging and full injection history at a glance

2. PepTracker: Dose Log
Best for: GLP-1 and testosterone users who want protocol templates and syringe math baked right in.
PepTracker helps you create structured protocols and schedule injections with spot-on volume calculations. It handles peptides, GLP-1s, and TRT, so you can manage multiple compounds without switching between apps. The highlight is the syringe volume calculator: tell it your vial concentration and dose, and it tells you how many units to draw. iPhone-only, and it eliminates the guesswork from unit conversion.
3. Smart Peptide Tracker
Best for: Android users managing research stacks that include blends and pre-mixed vials.
This tracker handles single compounds, custom blends, and complex mixtures all in one interface. Its built-in reconstitution calculator manages BAC water ratios and dosing math automatically, so you don’t have to keep a separate calculator handy. The blend tracker is the real highlight. You can log custom peptide combinations and see their combined dosages without manual addition. It’s a solid pick if your stack isn’t just one vial.
4. PepCalc: Peptide Calculator
Best for: quick, ad-free reconstitution calculations on Android.
PepCalc keeps things simple: you plug in peptide quantity, BAC water volume, and desired dose, and it shows the exact measurement on a syringe. It includes a syringe library that matches real-world insulin and TB syringes, saving you from those “which line do I pull to?” moments. You can save and edit your calculations for later doses, which is handy when you’re running a consistent protocol.
5. Regimen: Peptide Tracker
Best for: anyone who wants to see how their medication levels change over time.
Regimen supports over 150 compounds with custom scheduling and injection reminders, but the real difference is its half-life visualization. After you log a dose, it estimates how much medication is still in your system and graphs it, so you understand peak and trough timing intuitively. The reconstitution calculator is also built in, which keeps the whole process inside one app instead of bouncing between tools.
6. Injection Tracker
Best for: rotation tracking that prevents tissue damage from frequent injections.
This Android app puts a visual body map front and center. You mark each injection site, and it remembers where you’ve been, warning you when you’re overusing an area. It supports custom peptide protocols, GLP-1s, and biologics with a dose diary, so it’s more than just a map. If you’re pinning regularly, the site memory alone can save you from irritation and scar tissue buildup.
7. Shotsy GLP-1 Tracker
Best for: weight loss injection tracking with clinical medication level estimates.
Shotsy focuses squarely on GLP-1 shots and pills, offering smart scheduling and reminders. Its analytics dashboard estimates current medication levels based on published clinical data, giving you a sense of whether you’re in a peak or trough. That context can be useful if you’re trying to time side effects or appetite suppression. It’s an iOS-only app that’s tightly tailored to the weight loss crowd.
8. MeAgain
Best for: simple GLP-1 shot-day prep with a clear last-site memory.
MeAgain keeps things minimal: pre-injection reminders, a record of where you last injected, and a spot to log any symptoms. The last-site memory is the core feature. It shows exactly where your previous shot went, so you don’t accidentally hit the same spot twice. That straightforward design makes sticking to proper rotation easy, even if you’re not interested in tracking every detail of your cycle.
9. Anabolic Steroid & TRT Tracker
Best for: managing full anabolic, TRT, or SARM cycles alongside peptide logs.
This tracker handles comprehensive dose logging, detailed injection site tracking, and a precise dose calculator for cycles that go beyond peptides. It supports stacking, PCT planning, and long-term progress logs, so you’re not just tracking injections, you’re tracking the whole plan. The advanced injection site tracker can manage multiple compounds per day and alerts you when it’s time to rotate, which is essential when pinning frequency increases.
How we picked these apps
We tested each app against what peptide users actually need: fast dose logging, on‑time reminders, reconstitution math you can do without a scratchpad, and site rotation that helps prevent tissue damage. We leaned toward apps with clean, no‑nonsense interfaces and avoided any that hid key features behind aggressive paywalls. The list covers both iOS and Android, so you’ll likely find something that fits your phone, whichever peptra alternative you go with.
Frequently asked questions
What is peptra?
Peptra refers to a manual peptide tracking approach that often relies on scattered notes, memory, or spreadsheets. That’s exactly what the apps in this list are designed to replace with organized logging and reminders.
Are these apps free?
Some have free tiers with basic functionality, but Peptide Tracker: Cycle offers a complete premium experience without clutter or ads, which is why it’s our top recommendation.
Which app helps with reconstitution?
PepCalc and Smart Peptide Tracker both offer dedicated reconstitution calculators that handle BAC water ratios and dosing math on the fly, so you don’t need a separate conversion tool.
The verdict
If you want to ditch spreadsheets and stop playing “when did I last inject?” games, Peptide Tracker: Cycle is the best all-around peptra alternative. Its smart reminders, protocol builder, and auto-calculated dose logging give you back the mental bandwidth to focus on your goals instead of your notes. Get Peptide Tracker: Cycle for iOS here.
