Track your whole protocol free — then find out whether it's working with Pro. Every dose runs through the compound's half-life, so you see estimated active levels rather than a list of what you typed.
Free — unlimited compounds, protocols and history. No ads. No account.



What it does
Most trackers store what you typed. This one runs every dose through the compound's half-life, so the chart shows an estimate of what may still be active in your system — not the last thing you logged.

Log a panel by hand for free, or let Pro read it straight out of your portal's PDF. Then put a dose, a body metric and a lab marker on one chart and see whether they actually move together.

Set a target weight or body-fat percentage and the app projects when you will reach it from your own recent trend — not a generic curve, and measured from the day your protocol started. The band updates as the trend does, so a stall shows up as the date moving, which is the earliest honest signal that something needs changing.

Lots, suppliers, cost per vial and reconstituted expiry. The reconstitution calculator draws the syringe filled to the exact unit to pull, so you are not doing concentration arithmetic at the counter.

Put the price on a vial once and it follows every dose you log — per dose, per week, per month, and what is still sitting in the fridge. Then every vendor you have bought that compound from is ranked by cost per mg of actual compound, cheapest first, so a bigger vial at a bigger price cannot flatter a worse deal.


Where it goes further
Half-life curves, injection maps and reconstitution maths are table stakes now — this app has all of them, free. The difference is what happens after you have been logging for three months and want to know whether any of it worked.
Blends are stored as structured components, so if the same compound reaches you from two protocols on the same day, Today adds them together.
Arithmetic on the numbers you entered — not medical advice. It never blocks logging, and it is free on every plan.
The evidence, drawn
Every one of these is generated from what you logged — no manual charting, no spreadsheet, no export step.




The handover
Thirteen pages generated from ninety days of logging, in one tap. It opens with the answer — every headline metric as start → current, with dates and change — then the charts and the full detail behind it.
Cycle and before/after photo sections are included when you have that data. The report is a Pro feature; CSV export of everything is free.
The other report
The same one-tap export, pointed at your money. Monthly spend, spend by compound, a cumulative curve, every vendor ranked by cost per mg — and the number nobody else works out: what reaching your goal will cost from here.
Works with
Over 200 compounds with half-life, dose ranges and mechanism — including the GLP-1s people are actually prescribed, from semaglutide to tirzepatide. There are guides for tracking a semaglutide ladder, reading tirzepatide progress past the scale and keeping a vial inventory that counts itself down.
Brand names are the property of their respective owners and are listed to show what the app can track. BioHack Track is not affiliated with, endorsed by or sponsored by any manufacturer.
Also on the timeline
Weight, appetite, sleep and side effects move on a hormonal schedule of their own. If you are not tracking that, a rough fortnight looks like the compound — when it may just be the luteal phase. BioHack Track puts the two on one timeline so you can tell them apart.
Most apps assume a 28-day cycle and a 14-day luteal phase. This one learns your own luteal length from the ovulations you have actually measured, and projects from that — so the estimate gets better the longer you log.
Estimates from your own logged history. Not for contraception or medical decisions. Cycle tracking is a Pro feature; it is off until you turn it on, and nothing about it appears in the app if you don't.

Free tool · no download needed
Enter your vial and the bacteriostatic water you are adding and it works out the concentration, the volume to draw and exactly where that lands on a U-100 insulin syringe. Same maths the app runs — open it in your browser, nothing to install.
Private by design
There is no sign-up and no password. Nothing to breach, because there is nothing to sign in to.
Your protocol lives on your device and syncs through your private iCloud, moving between your iPhone and iPad without passing through a server we operate.
Export everything as CSV or a full backup file whenever you want — free on every plan, because getting your own records out is not something to sell.
Questions
The honest answer is that it depends on whether you want a log or an answer. BioHack Track is free with no cap on compounds, protocols or history — most free tiers in this category stop at one or two compounds, a limited number of logs, or thirty days of history. Beyond logging, it is the only tracker that reads a lab panel straight out of your portal's PDF and turns your protocol into a report a prescriber will read.
Yes, and not as a trial. Unlimited compounds, protocols and vials, no history limit, no ads and no account. Dose logging, half-life levels, titration phases and cycles, reminders, inventory, the reconstitution calculator, the 200+ compound library, injection-site rotation and manual bloodwork entry are free permanently. Pro is optional.
Yes. Provider is $19.99 a month or $199.99 a year and adds a patient roster with no cap on how many people are on it. A patient exports a record from their own app and sends it to you; you import it, read every lab, metric and dose as a chart, see what changed since their last record, write private notes and notes meant for them, record visits, propose starting, changing, pausing or stopping a protocol, send lab results and visit notes back into their record, and export a printable patient file for the chart. Patient records are stored only on your device, in a separate database that is never synced to iCloud. Provider includes everything in Pro. BioHack Track is a record-keeping tool: it does not prescribe, and a change sent through it is not a prescription.
The part that answers whether it worked: importing a lab panel from your portal's PDF, reading a smart-scale photo, body composition trends, before-and-after photos, dose-versus-lab correlations, Biological Age, a doctor-ready PDF, cost reports, certificates of analysis and household profiles. $2.99 a month or $32.99 a year. No trial — the free tier is the trial, and it does not expire.
Yes. Semaglutide, tirzepatide and retatrutide are in the library with half-life data, and the app handles the weekly cadence, titration schedules and pen or vial inventory that go with them. It also tracks TRT, HRT, peptides, supplements and anything you add yourself.
Over 200 compounds with half-life, common dose ranges, mechanism and cautions — BPC-157, TB-500, ipamorelin, CJC-1295, GHK-Cu, tesamorelin, MOTS-c, KPV, semax, selank and the rest — plus 21 pre-made blends with per-component milligrams so you can dose by a single ingredient. Anything missing you can add yourself.
Yes, and it draws the syringe. Enter your vial size and the bacteriostatic water you added, and it shows the concentration and the exact unit to draw to on a U-100 barrel. Your vial then counts itself down as you log, in doses rather than millilitres.
Nothing is deleted. Every dose, lab result, photo, scan and profile stays exactly where it is; the Pro features lock and the data does not. It all returns the moment you resubscribe, with no restore step. Backup, restore and CSV export are free on every plan and always will be.
There is no account and no password, so there is nothing to sign in to and nothing to breach. Your protocol lives on your device and syncs through your own private iCloud, moving between your iPhone and iPad without passing through a server we operate. Nothing is sold, shared or used to train anything.
Yes, and it is free. Importing your existing history costs nothing, because charging someone to move in is charging them at the exact moment they are deciding whether to bother.
That is your decision, but the arithmetic is not. Whatever volume you choose, the calculator on this page turns your vial size and water volume into a concentration and the exact number of units to draw on a U-100 syringe. More water means a larger, easier-to-measure draw for the same dose; less water means a smaller one. The app never recommends an amount to take.
Units are just hundredths of a millilitre on a U-100 syringe. Divide your dose by the vial's concentration to get the volume, then multiply by 100. The calculator above does it for you, and the app draws the syringe filled to that mark so you can check it against the barrel in your hand.
Half-life is how long it takes for half of a compound to clear. It matters because it decides how much is estimated to still be active when your next dose lands — BPC-157 halves in about five hours, TB-500 in about two and a half days, semaglutide in about a week. The app models every logged dose against its half-life, which is why the levels chart shows a curve rather than a list.
Yes. Every dose records a site, the next site in your rotation is shown before you log so you know where to go, and a body map lets you override it. Rotation advances automatically as you log.
Yes. Testosterone cypionate, enanthate, HCG and the rest are in the library, and the app handles intramuscular and subcutaneous routes, oil-based volumes, weekly and twice-weekly cadences, and bloodwork alongside them.
Yes. Blends carry per-component milligrams, so you can dose by the blend total or by one ingredient and the app converts between them. It also warns you if a compound reaches you from two protocols at once — including the portion hidden inside a blend.
Yes. BioHack Track is on iPhone, iPad and Android. The iPhone version syncs through your private iCloud; the Android version syncs through your own Google account, and both work fully offline.
Yes, with Pro. A household profile keeps a second person's protocols, inventory, doses and labs completely separate from yours, with its own reminders — no second account and no second phone.
Settings has a full CSV export and a complete backup file, both free on every plan. Your dose history, labs, check-ins and inventory come out in a format you can open in Excel or Numbers, or re-import later.
Yes, with Pro, and it is deliberately separate from protocol cycling. Turning it on adds a Cycle card to Today with period logging, phase and next-period projections, and a cycle overlay on your wellness charts — so you can see how a compound lands against where you are in your cycle rather than treating every week as identical. Projections are estimates for tracking only, not for contraception or medical decisions.
Two different things that share a word. An on/off cycle is part of a protocol — weeks on, weeks off, with reminders that follow it — and that is free. Cycle tracking means menstrual cycle logging with phase overlays, and that is a Pro feature.
No. It is a personal tracking and organisation tool. It does not diagnose, prescribe, or recommend doses, and the compound library is general-knowledge reference you can edit. Decisions about what to take belong with you and a qualified prescriber.
