Comparisons
These pages are written by the makers of one of the apps being compared, which is exactly why they are built around tests you can run yourself rather than claims about what anyone else does. Feature lists date within weeks; a ten-minute test in both apps does not.
How to choose a peptide tracker
Twelve questions that separate a tracker that survives a year from one you abandon in three weeks.
Buying guide
Peptide trackers vs GLP-1 trackers
Two categories built on incompatible assumptions — and why people who need both end up with two apps.
Category comparison
Spreadsheet vs app
The honest case for a spreadsheet, the honest case against it, and how to build one properly if you choose it.
Category comparison
PepCycle vs Shotsy
A GLP-1-focused tracker versus a format-aware one — what to test if you take both pens and vials.
Head to head
PepCycle vs Glapp
Calculator-led GLP-1 tooling versus a full record — and why a calculator is not a log.
Head to head
PepCycle vs PeptIQ
Two peptide-first trackers — where the data models differ and what to test before committing.
Head to head
PepCycle vs Protocol
Cross-platform breadth versus iPhone depth and local-first data — a genuine architectural trade-off.

Our rule for these pages
We never assert that a competitor lacks a feature. Products change weekly, a wrong claim is unfair, and you have no reason to take our word for it anyway. Instead, every comparison describes the other product by its own public positioning, states plainly what PepCycle does, and hands you a checklist. Where PepCycle is the wrong choice — Android, for one — we say so directly.
Frequently asked questions
Can I trust a comparison written by one of the apps?
Only as far as it is verifiable. That is why these pages are built around tests you can run yourself in ten minutes rather than claims about what a competitor does or does not do — app features change constantly, and a claim written today is often wrong within a month.
What is the fastest way to compare two trackers?
Test five things in each: a 200 mg vial, a three-peptide blend, an every-3-day schedule, editing a diluent volume on an existing vial, and backdating an entry eleven days. Five minutes per app tells you more than any article.
Is PepCycle available on Android?
No. It is iPhone-only, because the log is stored on-device and synced through your personal iCloud rather than a server. If you use Android, a cross-platform tracker is the right choice and we would rather say so.
Log it once, keep it forever
PepCycle turns the numbers on this page into a running record: every dose, vial, site and side effect in one place — stored on your iPhone and backed up to your own iCloud.
