Peptide Protocol
for biohackers.
Stacks of three to five peptides at once is a common biohacking pattern — a healing stack (BPC-157 + TB-500), a GH stack (CJC + Ipa), and something cosmetic (GHK-Cu) running simultaneously, each on their own cadence, each with their own vial. The complexity isn't pharmacological, it's logistical. Peptide Protocol is built to keep that logistics layer in one screen — multi-protocol Today view, blend math, vial inventory, exportable data — without forcing you into a cloud account.
Download Peptide Protocol — FreeWhat multi-protocol stacks need
Six things that distinguish a usable stack tracker from a single-medication app.
| Parallel protocols | Run as many simultaneous protocols as you need. Each has its own compound(s), cadence, dose, schedule, and inventory. |
|---|---|
| Blend support | Co-vialled stacks (CJC-1295 / Ipamorelin most common) get first-class blend objects — set per-peptide dose, get one unit count. |
| Vial inventory | Each vial: mass, BAC water, lot, expiry, remaining doses. Low-stock alerts surface in the weekly report. |
| Rotation across stack | Body-map cooldowns are global — if BPC-157 hit your right deltoid yesterday, today's TB-500 site suggestion knows. |
| Export everything | CSV + JSON exports. Pipe the dose log and check-ins into your own Notion / Obsidian / spreadsheet workflow if that's your thing. |
| Local-first | Default storage is on-device. No account, no cloud, no analytics SDK shipping your stack data anywhere. |
Built for the stack
Three features that matter when you're running more than one peptide at a time.
One Today screen for the whole stack
Daily, twice-weekly, and weekly cadences sit on the same surface. Today's BPC-157 next to today's GHK-Cu next to this week's Tirzepatide. Streak counts per protocol, plus a stack-level adherence number.
Calculator handles every preset
40+ peptide presets with sensible BAC water defaults. mg ↔ µg ↔ IU conversions for HGH, blend math for CJC / Ipa, the same engine across the lot. Your reconstitution math is one tap regardless of what you're running.
Inventory that thinks ahead
Each vial tracks remaining doses against current cadence, so you see "Tirzepatide vial finishes May 24" and can re-order before the gap. Rotation history exports cleanly so a multi-month stack stays auditable.
What it looks like
Stack tracking — common questions
How many peptides can I run in parallel?
There is no fixed cap. Run as many parallel protocols as your stack actually needs. Each has its own cadence, dose, vial inventory, and rotation rules. The Today screen aggregates everything due across the stack so the day's work is one screen, not five.
Does the app handle blends co-vialled with two peptides?
Yes. Blends are first-class. Define a vial with two compounds and their respective masses, set per-peptide dose targets, and the calculator returns the unit count that delivers both in one draw. The most common blend — CJC-1295 / Ipamorelin — has a dedicated preset.
Can I export everything for analysis?
Yes. Settings → Export gives you a CSV of the full dose log, check-ins, weight history, and inventory. A JSON export is available for full restore (useful when changing devices or stacking the data into a personal analytics workflow).

Many of the peptides commonly run in stacks are research compounds, prescription-only medications, or restricted under WADA in competition.
