Protocol vs Regimen
Two apps for tracking peptide protocols. Different architectures, different pricing, different audiences. Here's what separates them.
Protocol — full home screen
The app Regimen users switch to.
Protocol users log an average of 847 doses in their first year. The daily checklist, injection site map, vial expiry tracker, and AI research assistant are all in one place — no cloud required, no subscription to start.
Choose Protocol if
- ✓Privacy is non-negotiable — on-device, no account, no cloud
- ✓You want Stealth Mode (icon changer + Face ID)
- ✓You need lab work and blood panel tracking
- ✓You want the 81-compound research library
- ✓You run complex multi-compound stacks
Consider Regimen if
- ·You want cross-device cloud sync as a primary feature
- ·You're tracking simple single-compound protocols
- ·You're comfortable with a monthly subscription

The Key Differences
Privacy and data architecture
This is the biggest structural difference. Protocol stores everything on your device — no server receives your dose logs, compound list, or injection history. There is no account to create, no email to provide, no cloud backup unless you choose to export manually. Regimen uses cloud sync, which means your health data lives on their servers. For peptide users tracking TRT, GLP-1, or compounds in a legally gray area, that distinction matters.
Pricing
Regimen charges $4.99/month — $60/year — for full access. Protocol's core dose tracking is free with no time limit. Pro features (AI research queries, advanced analytics, priority support) are available as an upgrade. If you just need reliable dose logging, vial management, and injection site tracking, Protocol Pro is optional.
Research depth
Protocol includes 81 compound profiles with typical dosing ranges, mechanism notes, PK half-life curves, common stacks, and side effect profiles. Regimen's research depth is more limited. If you're running a stack you haven't run before and want to look up the data without leaving the app, Protocol is the more complete research tool.
Unique Protocol features with no Regimen equivalent
Three Protocol features have no direct equivalent in Regimen: Stealth Mode (disguise the app entirely with a custom icon, require Face ID to open), the 3D injection site rotation map (tap to log, see your full rotation history, get recommendations), and the AI synergy radar chart (scores your stack across synergy, redundancy, side effect risk, evidence quality, and cost). Lab work tracking — new in v3.1.0 — lets you log blood panel results alongside your protocol and export them to your healthcare provider.

AI Synergy Radar — not in Regimen
AI scores your stack across six dimensions: synergy, redundancy, side effect risk, evidence quality, cost, and complexity. Builds before you run.
