PeptidePal alternative: a ledger, not a compound library
Overlapping scope, opposite editorial stance. Facts from Apple's App Store listings, checked 30 July 2026.
PeptidePal and Pinned cover much the same ground — peptides, GLP-1s and TRT in one app, both with a reconstitution calculator. The real difference is the reference layer: PeptidePal's listing describes a 50+ compound library with mechanisms, half-lives and commonly-researched dosing ranges, plus curated stacks and an educational AI advisor. Pinned has none of that on purpose, which is less a feature gap than a different answer to what an app should tell you.
The scope is genuinely similar
Most comparison pages in this category can lean on a scope difference. This one cannot. PeptidePal's own listing describes GLP-1 tracking, research peptides and TRT in one place, with a reconstitution calculator that draws a live syringe illustration and warns when the maths does not fit the barrel. Pinned covers peptides, TRT, HRT and GLP-1 in one ledger, with reconstitution and unit conversion running in both directions. Those are close to the same product description.
PeptidePal is also considerably more established: 4.68 stars from 3,231 ratings as of 30 July 2026, against Pinned's zero. Anyone choosing on evidence of use should choose PeptidePal today.
The numbers, as of 30 July 2026
Both required iOS 18.0 on that date, so device reach is not a deciding factor between these two. Ratings move; the date is stated because a number without one is a claim, not a fact.

Where the two apps actually diverge: the reference layer
PeptidePal's listing describes a library of 50+ peptides with mechanisms, half-lives, commonly-researched dosing ranges, side effects and contraindications, a set of pre-built multi-compound stacks you can spin up with sane defaults, and an educational AI advisor. That is a substantial amount of work and it is clearly what many of its users are there for.
Pinned publishes none of it. Not because it would be hard to write, but because Pinned's Terms state the app does not recommend compounds, sources, amounts or protocols — and a screen full of ranges and pre-built stacks is difficult to square with that, whatever the disclaimer says underneath. Pinned will do arithmetic on numbers you enter. It will not suggest what those numbers should be.
This is the honest fork in the road. If you want an app that also teaches you the landscape, Pinned is the wrong choice and will feel empty. If you already know what you are running and want a record that stays out of it, the empty part is the point.
Smaller differences worth knowing
A few concrete things separate the two beyond the editorial stance.
- HRT: Pinned names hormone replacement alongside TRT as a first-class category rather than a subset of testosterone protocols
- Languages: Pinned ships in English, Dutch, French and German
- Storage: Pinned keeps the record on the device with no account and no cloud sync — which also means no cross-device sync and no server-side backup
- Export: Pinned exports the full record as CSV or PDF from inside the app, as part of Pinned Pro
- Free tier: Pinned's first compound is free with no time limit; the full calculator and export are Pro
Which to pick
Choose PeptidePal if you want the compound reference and the curated stacks, if a live syringe illustration helps you trust the calculation, or if 3,231 ratings are what makes you comfortable trusting a health app with your record.
Choose Pinned if your record spans TRT or HRT as well as peptides and GLP-1s, if you want it in Dutch, French or German, or if you would rather an app never volunteered an opinion about what you are taking.
FAQ
- Does Pinned have a compound library?
- No. Pinned lets you log named peptides, GLP-1s, testosterone and HRT protocols, orals, nasal sprays and anything custom you enter, but it does not publish mechanisms, half-lives or dosing ranges for them. That is a deliberate limit, not a roadmap item.
- Which app has the better reconstitution calculator?
- They solve the same problem differently. PeptidePal's listing describes a live syringe illustration with an over-capacity warning. Pinned's runs in both directions — vial size and diluent volume to units, or a chosen unit count back to the dilution — and carries concentration, remaining volume and discard dates per vial. Try both; the calculator is reachable on your first compound in Pinned.
- Is PeptidePal more trustworthy because it has more ratings?
- More ratings mean more people have used it and said something publicly, which is real evidence and Pinned has none of it. It is not the same as an audit of either app's maths or privacy. Both are worth checking yourself against a known calculation before you rely on them.
- Can I move my history from PeptidePal to Pinned?
- There is no import path between them. Pinned lets you backfill past doses without breaking the record, so a manual catch-up is possible, but a long history will take real effort to re-enter.
- Do either of these apps recommend a protocol?
- Pinned does not. It is a personal record-keeping tool, not a medical device, and it provides no medical advice, diagnosis, treatment or dosing recommendations. Always consult a licensed clinician before starting or changing anything.
