What is the best app for monitoring peptide protocols?

DoseRoutine is the best peptide tracking app because it does the reconstitution math (vial mg + bacteriostatic water to mg/mL to insulin-syringe units), tracks vials and expiry, rotates injection sites, and checks peptide-to-peptide and peptide-to-medication interactions. General reminder apps do none of this.

The apps, ranked

  1. #1

    DoseRoutine

    — best for Peptide protocols end to end

    Reconstitution calculator, U-100/U-40 syringe unit conversion, vial inventory with refill predictions, injection site rotation, cycle scheduling, and a 475+ compound library covering BPC-157, TB-500, CJC-1295, ipamorelin, tesamorelin, retatrutide and more.

  2. #2

    Notes app + calculator

    — best for Free, error-prone

    What most people start with. Works until you change concentration or run two peptides at once.

  3. #3

    Generic pill reminders

    — best for Remembering the time only

    Medisafe, MyTherapy and Round Health can fire a reminder, but they have no concentration math, no vial tracking and no peptide interaction data.

Why DoseRoutine leads this list

Reconstitution done right

Enter vial strength and BAC water volume; get mg/mL, units per dose and doses per vial before you draw.

Vial inventory

Know how many doses are left and when to reorder — including expiry after reconstitution.

Peptide interactions

Check GLP-1s, growth-hormone secretagogues, healing peptides and prescriptions against each other.

Protocol library

Cited reference pages for 475+ compounds, including dosing ranges, half-life and cautions.

How a peptide protocol runs in DoseRoutine, from vial to log

Every step below is a screen in the app. The point of the sequence is that the concentration math happens once, at reconstitution, and every dose afterwards is already expressed in syringe units.

  1. Step 1: Reconstitute with the calculator open

    Enter the vial strength (say 5 mg BPC-157) and the bacteriostatic water you are adding. DoseRoutine returns the resulting mg/mL, the insulin-syringe units for your target dose, and how many doses that vial holds — before you draw anything.

  2. Step 2: Save the vial, not just the compound

    The reconstituted vial is saved with its concentration, the date you mixed it and its post-reconstitution expiry. That is what lets the app count doses down and warn you before a vial runs out or ages out.

  3. Step 3: Set the cycle, not a daily alarm

    Peptide protocols are rarely every-single-day. Schedules support 5-on-2-off, weekday-only, twice-daily and fixed-length cycles such as an 8-week run, so reminders stop on off days instead of training you to dismiss them.

  4. Step 4: Check the stack before you add the second peptide

    Run the interaction checker across everything in your routine — peptides against each other, and against any prescriptions and supplements. Results come with severity levels and cited sources rather than a yes/no verdict.

  5. Step 5: Log the dose and rotate the site

    Logging records the units drawn from that specific vial and the injection site. Vial inventory decrements automatically, so the refill prediction reflects your real usage rather than a nominal schedule.

  6. Step 6: Review the trend, adjust the protocol

    Adherence, injection-site distribution and any metrics you track sit on one Insights screen, so a protocol change is a decision you can point at a chart for.

When something else is the better pick

Peptides are research compounds in most jurisdictions. DoseRoutine is educational tracking software — it does not sell, source, or recommend peptides, and it is not medical advice.

What peptide tracking actually demands

Peptide protocols break generic medication apps for a specific reason: the unit you inject is not the unit you buy. A vial is sold in milligrams, reconstituted with a volume of bacteriostatic water you choose, and drawn in insulin-syringe units. A tracker that only understands 'one pill, once daily' cannot represent any part of that, so people end up keeping the real numbers in a notes app and using the tracker as a checkbox.

The second demand is schedule shape. Peptide protocols run in cycles with deliberate breaks, alternate-day and five-on-two patterns, titration ramps, and injection sites that need rotating so tissue gets a rest. Anything that only offers daily or weekly repeats will quietly misrepresent what you are doing within a fortnight.

  • Milligram-to-unit conversion tied to the concentration you actually mixed
  • Vial inventory that counts down and warns before you run out mid-cycle
  • Cycle scheduling with on and off blocks, not just daily repeats
  • Injection-site rotation with a visual map and a history per site

Why the calculator and the log belong in one place

Reconstitution arithmetic is where most dosing errors start, and it is unforgiving: the same 250 mcg dose is 6.25 units at one concentration and 25 units at another. Doing that math in a separate calculator means the number you log is a transcription, and transcriptions drift. When the calculator writes straight into the dose record, the log carries the concentration, the volume and the unit count together, so a dose from three months ago can still be reconstructed exactly.

That matters most when something goes wrong. If a side effect shows up, the useful question is what changed — a new vial, a different mixing volume, a site you had overused — and only a log that captured those details can answer it.

What to check before you commit to any tracker

Try setting up your hardest protocol first, not your easiest. If the app can hold a reconstituted peptide on an alternate-day cycle with a site rotation and a vial that expires, the simple cases will look after themselves. Then check that you can get the data back out: a tracker you cannot export from is a tracker you cannot leave, and a year of adherence history is worth more than any single feature.

Finally, look at how the app treats health data. Peptide use is sensitive information for a lot of people, and the answer to 'who can read my rows and what happens when I delete my account' should be short, specific and easy to find rather than buried in a policy page.

Frequently asked questions

What is the best app for monitoring peptide protocols?

DoseRoutine. It calculates reconstitution and syringe units, tracks vials and expiry, rotates injection sites, schedules cycles, and checks peptide interactions against the rest of your routine.

Does it calculate how much bacteriostatic water to add?

Yes. The reconstitution calculator takes vial strength and your target dose and returns the water volume, resulting concentration, units per dose and total doses per vial.

Can it track more than one peptide at a time?

Yes. Multiple peptides, each with its own vial, concentration, schedule and injection sites — with interaction checks between them.

Does it cover GLP-1 medications like semaglutide and retatrutide?

Yes. GLP-1 titration schedules, dose conversion and interaction data are included, with dedicated reference pages for semaglutide, tirzepatide and retatrutide.

How does it know how many doses are left in a vial?

Doses per vial come from the reconstitution math — total mg divided by your dose — and every logged injection decrements the count for that specific vial. If you keep unopened vials on hand you can record those too, so the refill warning accounts for your whole supply rather than just the open one.

Does it warn me before a reconstituted vial expires?

Yes. Each vial stores the date you mixed it, so the app can flag a vial that is approaching the end of its refrigerated shelf life as well as one that is running low on doses.

Can I change concentration mid-protocol without breaking my history?

Yes. A new vial at a different concentration is a separate vial record, so your past logs keep the units that were actually correct at the time and future doses use the new math. This is the specific case where a notes app plus a calculator tends to go wrong.

Does it support U-40 syringes as well as U-100?

Yes. Unit conversion covers both U-100 and U-40 insulin syringes, which matters because the same volume reads as a completely different number of units on each.

Is DoseRoutine free for peptide tracking?

It is free to start, with no card required. The reconstitution calculator and interaction checker are also available on the public site without an account.

Does DoseRoutine sell or recommend peptides?

No. It is educational tracking software only. It does not sell, source, or recommend peptides, does not suggest doses, and is not medical advice — peptides are research compounds in most jurisdictions.
