Peptide tracker app and calculator

Your peptide tracker for the whole routine.

PepMetrics keeps peptide doses, protocols, reminders, meals, hydration, weight, and check-ins in one calm record, with a free reconstitution calculator and a weekly view built from what you log.

Free to start. One peptide included. No card required.

Mark one scheduled action Taken and PepMetrics connects its compatible vial, today's calendar, the next check-in, and the weekly record. Undo restores the full preview.

From scattered to steady

A whole routine is more than a reminder.

A dose, a meal, a glass of water, and an evening check-in are easier to carry when each action leaves the next one in view.

A calm record, built from what you choose to log.

One connected day

One day with PepMetrics.

The record grows one ordinary action at a time, while the next useful detail stays close enough to reach.

Calculator to protocol

Start with the math. Keep the record.

Results are calculated from the values you enter.

PepMetrics calculates the draw from your inputs. It does not choose a dose for you.

Public research1 source

What do public sources say about safer vial handling?

CDC infection-control guidance says to prepare medications in a clean area, disinfect vial access diaphragms, and use a new needle and syringe when entering a medication container.

That is general public guidance, not an instruction for your protocol.

Source 01CDC injection safety guidance
Calculator explanationRecorded inputs

Why does the result show 40 units?

Your entered 10 mg vial and 2 mL water volume produce a 5 mg/mL concentration. A recorded 2 mg dose uses 0.4 mL.

A U-100 syringe has 100 units per mL, so 0.4 mL maps to the 40-unit mark.

Math receipt2 mg / 5 mg/mL = 0.4 mL = 40 units

Common questions

Know the boundaries before you begin.

Straight answers about daily tracking, the calculator, installation, reminders, sync, export, AI Guide, and Pro.

Every answer is here in the page, with no account or script needed to read it.

What does PepMetrics track?

PepMetrics keeps protocol schedules, dose actions, compatible linked-vial context, meals, hydration, weight, appetite and symptom check-ins, reminders, calendar history, and a weekly review in one place.

Does PepMetrics provide medical advice?

No. PepMetrics records plans and observations and offers educational research with sources. It does not prescribe, diagnose, treat, or adjust your protocol.

What inputs and syringes does the calculator support?

Enter your desired dose, vial strength, and water volume. PepMetrics calculates mL and U-100 units and supports 30-unit, 50-unit, and 100-unit U-100 syringes.

Can I track more than one peptide?

Yes. Free includes up to one unique peptide. Pro includes unlimited peptide tracking.

How do I install the app on iPhone or Android?

Open the Get the app guide for steps matched to iPhone, Android, or computer. No app store is required, and notification permission is requested only when you choose to enable reminders.

Open the Get the app guide
What do reminders require?

Reminders require a signed-in account with reminders enabled, a supported device and browser, notification permission, and an active notification subscription on that device.

Can I use PepMetrics without a connection?

Local actions can continue in supported flows and retry after reconnection. Account sync, AI Guide, and some browser features still need a connection, so complete offline operation is not promised.

How do sync and export work?

Signed-in records sync across devices. Settings can export sanitized tracking data stored on the current device as JSON, not a complete cloud-account export or a clinical report.

What does AI Guide do, and what is its privacy boundary?

AI Guide researches public sources and explains calculator math for educational use. Requests cross a separate AI provider boundary described in the privacy policy.

Can I cancel Pro?

Yes. You can manage or cancel your subscription from Billing in Settings.
