Where Peptide Protocol is stronger
Native app, not a web wrapper
Daily dose tracking belongs in a native iPhone app with notifications, Health integration, and offline support — not a browser tab. Peptide Protocol is built that way; PeptidePro is a paid web app.
Free web calculators
If you want just the math, you get it free here — no subscription. PeptidePro puts its calculator behind $99.99/yr.
Editorial review process
We publish our medical review process and editorial policy, with inline citations on our top glossary entries. Reference quality matters more than count.
Roughly 1/10th the price
Freemium vs. $99.99/year. For the daily tracking use case, PepidePro's pricing is hard to justify.
Where PeptidePro is stronger
Breadth of peptide encyclopedia
PeptidePro's 100+ peptide count is larger than our current 29 (scaling toward 60). If raw coverage is your priority, they have more entries today.
Clinician tooling
PeptidePro markets itself to clinicians with multi-patient features. We're consumer-first.
Which to pick
Pick Peptide Protocol if…
You want a native iPhone tracker, free web tools, and researched reference content — and you're not trying to manage many patients.
Pick PeptidePro if…
You need the largest peptide encyclopedia available, you're managing clients as a clinician, and web-only is fine.
How this page is maintained
This comparison is written by the Peptide Protocol team and is inherently biased toward our own strengths — we try to be fair about PeptidePro's, but the honest way to evaluate is to try both when possible. We update this page when feature sets change. If you spot something that has changed on either side, tell us.
