Protocol vs Peptify
Advanced peptide tracker with bloodwork
Which peptide tracking app is right for you?
Peptify leads on clinical depth. Protocol leads on complete protocol tracking.
Peptify is the most feature-rich competitor — 80+ biomarker bloodwork tracking, two-compartment PK modeling, and a deep compound database. If clinical-grade pharmacokinetics and lab correlation are your top priority, Peptify is impressive. But Protocol has a fundamentally different value proposition: it's the only app that tracks your entire protocol — peptides, supplements, and habits together. Protocol's bloodwork tracking is coming in the next version. Protocol also stores everything on your device with no account required.

Frequently asked questions
Is Peptify better than Protocol for bloodwork tracking?
Currently yes — Peptify has 80+ biomarkers with camera OCR import, which Protocol doesn't have yet. Protocol's bloodwork tracking (manual entry, key biomarkers, trend charts) is coming in the next version. If bloodwork correlation is your primary need right now, Peptify has an edge there.
Does Protocol have two-compartment PK modeling like Peptify?
Protocol's PK curve modeler uses standard one-compartment pharmacokinetic models showing peak, half-life decay, and optimal dosing windows across 1, 4, 8, or 12 dose schedules. Peptify uses two-compartment modeling which is more precise. Protocol's Active Levels chart shows all compounds simultaneously on one timeline — Peptify shows individual curves.
Can Peptify track supplements and habits with peptides?
No. Peptify tracks peptides and bloodwork. Protocol is the only app that lets you combine peptides, supplements, and daily habits into a single protocol with one adherence score — so your injury recovery stack tracks TB-500 injections, collagen powder, and your PT rehab routine together.
Which app is better for privacy?
Protocol. Everything stays on your device — no account required, no cloud sync, Apple-verified Data Not Collected. Peptify requires an account and cloud storage.
