PepCue vs PepTracker.
An honest disclosure first: we could not verify PepTracker's current feature set or pricing from public information, so this page does not pretend to a side-by-side checkmark table. What it does instead is set out exactly what PepCue offers, leave the other column blank wherever we cannot confirm something, and make the argument for why the layer around a dose log is the part worth comparing.
Last checked September 2026. Competitor features and pricing change, so verify on their own site or App Store listing before you decide.
You want the evidence behind each compound graded on a published model, free reconstitution math in a browser, and a site with nothing to sell you.
You have used PepTracker, it fits how you work, and a straightforward log is all you actually want. An app you already open every day beats a better app you forget about, and switching trackers costs you your history.
We have not verified PepTracker's feature list, pricing, ratings or review counts, so none of those appear below. Every cell in their column reads “Not verified” for that reason. If you know the app, trust your own eyes over this page.
Side by side, verifiable rows only.
| PepCue | PepTracker | |
|---|---|---|
| Price | Free to use. You can run a full protocol without paying, and there is no subscription gate on logging, schedules, the calculators or the evidence library. | Not verified. Check the App Store listing for current pricing. |
| Account required | Not required. Tracking starts without an account, and the browser calculators need no sign-up either. | Not verified |
| Dose logging and history | Per-compound schedules with reminders, a calendar that stamps itself as you log, and a month view of every dose taken. | Not verified |
| Evidence grading | Every compound carries an S to F evidence tier scored on six axes: human evidence, preclinical depth, mechanism confidence, safety clarity, regulatory clarity and practical relevance. | Not verified |
| Scoring model published | Yes. The full six-axis model, the tier thresholds and a worked example on a real compound are published on the methodology page. | Not verified |
| Citations | 306 cited sources across 69 compound profiles, plus a generated research index of 274 unique PubMed records, every one pulled from NCBI and re-resolved against live PubMed by an audit script kept in the repo. | Not verified |
| Compound library | 69 compound profiles covering regulatory status, mechanism, what the published evidence actually shows, and safety. | Not verified |
| Calculators without an account | 9, free in the browser with no account and no install: reconstitution, blends, GLP-1 titration, pen clicks, vial longevity, unit conversions and BAC water. | Not verified |
| Cost tracking | Enter a vial price and PepCue reports per-dose, weekly, monthly and yearly spend plus days of supply left. | Not verified |
| Affiliate codes or vendor rankings | None. PepCue sells no peptides, ranks no vendors, takes no kickbacks and places no affiliate codes. | Not verified |
| Dosing guidance | Never. PepCue explains compounds and does the arithmetic on numbers you enter. It does not tell anyone what to take. | Not verified |
| Where your data lives | Protocols, doses, inventory, weights and check-ins are stored on your device rather than on our servers. | Not verified |
What PepCue does differently.
Logging is table stakes. Any competent tracker will record that you took something on a date, and the differences between one log screen and another are mostly taste. The interesting question is what the app knows about the thing you just logged, and that is where PepCue is built differently from a tracker-first product.
Every compound in the PepCue library carries an S to F evidence tier, and the tier is computed rather than declared. Six axes feed it: how much controlled human evidence exists, how deep the preclinical work goes, how well the mechanism is actually characterised, how well the safety profile is known, whether a regulator has reviewed the compound, and whether the outcome that was studied is the outcome people are chasing. The model is published in full, thresholds included, with a worked example on a real compound so you can audit a grade instead of trusting it.
The grades are frequently unflattering, which is the point. A compound can have deep animal data and a zero on human evidence, and that combination is the norm rather than the exception in this category. Safety clarity measures how well a safety profile is known, so no human toxicology means a floor score, because unknown is not safe. Across 69 profiles there are 306 cited sources, and a generated research index holds 274 unique PubMed records re-resolved against NCBI by an audit script in the repo, so a citation that stops resolving gets caught.
The practical layer is free and open. 9 calculators run in the browser with no account and no install, covering reconstitution, blends, vial longevity, GLP-1 titration, pen clicks and unit conversion. That is deliberate: the arithmetic is where the real risk of harm sits, and gating it behind a paywall or a sign-up puts the barrier in the worst possible place. Nothing on the site is for sale, no vendor is ranked, no affiliate code is placed, and no page tells anyone what to take.
Where PepTracker is stronger.
The fair thing to say about PepTracker is that we do not know enough to grade it, and a page that scored an app it had not verified would be doing exactly what this site exists to argue against. Take everything here as a description of PepCue with an empty column beside it.
There are also two real advantages any incumbent tracker holds over PepCue, and they apply whichever app you are already using. The first is your history. A log you have kept for months is worth something, migrating it is rarely pleasant, and a partial migration is worse than no migration. The second is habit. The tracker you actually open is the one that works, and adherence beats features every time.
If PepTracker suits how you think about your protocol, keep using it. The calculators and the compound library on this site are free and need no account, so you can use the part of PepCue you want without moving anything.
FAQ.
Is PepCue better than PepTracker?
We are not in a position to answer that, because we have not verified PepTracker's current features or pricing. What we can say is what PepCue offers: a graded compound library with the scoring model published, 9 free browser calculators with no account, and no affiliate codes or vendor rankings anywhere on the site.
Why are so many cells on this page blank?
Because filling them would mean guessing. A comparison table with invented checkmarks is worse than an honest blank, and a site that grades evidence for a living cannot fabricate a feature list for a competitor. Blank means unverified, not absent.
What does PepCue add on top of a dose log?
A graded evidence library, free reconstitution and blend math in the browser, cost tracking per dose and per month, estimated levels from your logged doses, and a record you can hand to a provider. The log itself is the least distinctive part of any tracker.
Does PepCue cost anything?
No. PepCue is free to use, a full protocol can be run without paying, and the website calculators and evidence library need no account at all.
