Best Peptide Tracker Apps for BPC-157, TB-500, and Complex Protocols (2026)

Peptide protocols are harder to track than almost anything else in the injectable medication space. You're often running multiple compounds simultaneously, each with its own dose in micrograms, its own injection schedule, its own reconstitution math, and frequently a cycle structure with on and off periods. Most medication apps break under this weight. Here are six that attempt to handle it, with a clear-eyed look at each.

Quick Reference: Top 3 Peptide Tracker Picks

1. DoneDose -- Best for multi-compound protocols with injection site rotation. Handles unlimited medications with independent schedules and a visual body map for tracking injection sites across compounds.
2. PepTracker -- Best peptide-specific app. Built for the peptide community with reconstitution calculators and compound-specific features.
3. SHOTLOG -- Best for fast daily logging. Minimal interface focused on getting your injection logged quickly without extra steps.

Individual App Reviews

DoneDose

DoneDose doesn't market itself as a peptide app specifically, but its architecture handles peptide protocols better than most dedicated options. The reason is straightforward: it was built for injectable medications with multi-medication support as a core design principle, not a feature added later. You can set up BPC-157 twice daily, TB-500 twice weekly, and whatever else your protocol includes — each with its own schedule, dose, and injection site history.

The visual body map for site rotation becomes particularly valuable with peptides because you're injecting frequently — often daily or twice daily. When you're putting a needle in your skin that often, disciplined rotation isn't optional. The color-coded site status shows at a glance which areas have been used recently and which are ready, across all your compounds.

Honest weakness: No reconstitution calculator. If you're mixing lyophilized peptides with bacteriostatic water and need to calculate concentration per unit, you'll need to do that math elsewhere or use a separate tool. This is a meaningful gap for peptide users specifically, and it's the feature most requested by the peptide community. For now, our peptide storage guide covers reconstitution basics, but in-app calculation would be better. For a detailed feature-by-feature comparison with PepTracker, see our DoneDose vs PepTracker breakdown.

PepTracker

PepTracker was built by and for the peptide community, and that focus shows in features no general tracker would think to include. The reconstitution calculator is the headline feature — input your peptide amount and BAC water volume, and it tells you how many units per injection for your target dose in micrograms. If you've ever stared at an insulin syringe trying to figure out how many tick marks equal 250mcg of BPC-157, this feature alone justifies the app.

The app handles multiple compounds and understands the peptide ecosystem. Compound profiles include commonly used dosing ranges, half-life information, and storage notes. The community around PepTracker tends to be knowledgeable and the app benefits from that feedback loop. If you're currently using PepTracker and wondering what else is out there, our PepTracker alternatives guide covers the landscape.

Honest weakness: Site rotation tracking is limited. PepTracker tracks which general area you injected but doesn't offer the visual body map or site-specific history that DoneDose provides. For daily injectors, this gap matters over time. The interface can also feel dense — there's a lot packed into the app, and it takes some time to set up a complex protocol.

SHOTLOG

SHOTLOG takes the opposite approach from PepTracker: minimal interface, fast logging, get in and get out. The design philosophy is clearly "log your injection in five seconds or less." For people who find detailed tracking apps burdensome and just want a reliable record of what they injected, when, and where, SHOTLOG delivers on that promise.

The app handles the basics well — you define your compounds, set reminders, and log with minimal taps. The history view is clean and the data is easy to review. For simple peptide protocols (one or two compounds, consistent dosing), SHOTLOG is genuinely pleasant to use daily.

Honest weakness: The simplicity that makes SHOTLOG great for basic protocols becomes a limitation for complex stacks. If you're running four or five compounds with different schedules and need to track reconstitution dates, vial usage, and detailed site rotation, SHOTLOG doesn't have the depth. It's a logging tool, not a protocol management system.

Peptide Log

Peptide Log sits in the middle ground between PepTracker's depth and SHOTLOG's simplicity. It includes basic reconstitution calculation, compound logging, and schedule management. The interface is functional and peptide-oriented — it understands that you're working in micrograms, that you're injecting subcutaneously, and that you probably have more than one vial in your refrigerator.

The app includes basic site rotation and some useful features around tracking vial usage and reconstitution dates, which helps you manage peptide freshness and know when to mix a new vial.

Honest weakness: The app can feel unpolished compared to the competition. Updates have been less frequent than PepTracker, and the multi-compound management isn't as smooth as DoneDose or Regimen for complex protocols. It works, but the user experience has room to improve.

Regimen

Regimen takes a protocol-management approach that works well for structured peptide cycles. You define your protocol — compounds, doses, schedule, cycle length — and Regimen tracks your adherence against that plan. This structure is particularly useful for peptide protocols because they're often time-bound: run BPC-157 for four weeks, take two weeks off, reassess. Regimen keeps the protocol front and center rather than treating each injection as an isolated event.

The app also handles TRT and other injectables, making it a reasonable single-app solution if your protocol spans multiple categories. Our DoneDose vs Regimen comparison covers where these two apps diverge for complex protocols.

Honest weakness: Not deeply peptide-specific. It doesn't include reconstitution calculators or microgram-level dose precision in the way PepTracker does. Site rotation is basic. Regimen's strength is the protocol structure, but the individual injection tracking details are thinner than specialized options.

The Pep Planner

The Pep Planner combines peptide tracking with planning features — helping you map out your protocol before you start, then tracking adherence during the cycle. It includes reconstitution guidance and some educational content about common peptide protocols. The planning-first approach is useful for people new to peptides who want to organize their protocol thoughtfully before injecting.

The app includes basic reminders and injection logging, and the interface is reasonably clean.

Honest weakness: The planning features are more useful at setup than during daily tracking. Once your protocol is running, the daily experience is basic compared to PepTracker or DoneDose. Site rotation tracking is limited, and multi-compound management gets unwieldy with more than two or three peptides running simultaneously.

How We Evaluated

We assessed each app against criteria specific to peptide protocol management:

• Multi-compound support. Peptide protocols frequently involve two to five compounds running simultaneously. We evaluated how each app handles multiple medications with independent schedules.
• Injection site rotation. Daily SubQ injections demand disciplined rotation. We weighted this heavily because peptide users inject more frequently than most other injectable medication categories.
• Reconstitution tools. Converting lyophilized peptides to injectable solutions requires math that's easy to get wrong. We evaluated whether each app helps with concentration calculations.
• Microgram-level dosing. Peptide doses are measured in micrograms, not milligrams. We looked for apps that handle this precision without forcing workarounds.
• Cycle management. Many peptide protocols have defined on/off periods. We evaluated whether each app understands cycle structures.
• Daily usability. When you're injecting one to three times per day, logging friction matters enormously. We timed how long it takes to log an injection in each app.

Frequently Asked Questions

What is the best app for tracking peptide injections?

For multi-compound protocols with injection site rotation, DoneDose offers the strongest combination of features. PepTracker is the best peptide-specific option with its reconstitution calculator. SHOTLOG works well for simple daily peptide logging. The best choice depends on your protocol complexity.

Do I need a peptide-specific tracker or can I use a general medication app?

General medication apps struggle with peptide protocols because they don't handle reconstitution math, microgram-level dosing, multiple daily injections of different compounds, or the short cycle-on/cycle-off scheduling that many peptide protocols require. A purpose-built app saves significant frustration.

Can I track multiple peptides in the same app?

Yes, if the app supports multiple medications. DoneDose, PepTracker, and Regimen all handle multiple injectable compounds with independent schedules. Some simpler apps like SHOTLOG may require workarounds for complex multi-peptide stacks.

How important is injection site rotation for peptides?

Very important, especially for daily SubQ injections. Repeated injections in the same area cause tissue irritation, bruising, and can affect absorption. With peptides that require daily or twice-daily injections, disciplined rotation matters even more than with weekly injectables.

Done Dose handles complex peptide protocols without forcing you into workarounds. Multi-compound tracking with independent schedules, visual injection site rotation across all your peptides, and a clean daily logging experience that doesn't slow you down when you're injecting twice a day.
