01 · Protocol Builder
Build any stack, your way.
Curated stacks or fully custom — pick peptides, set doses, schedule days on / off, add notes and reminders.
Built for every peptide protocol
The precision tracker for your protocol.
Build stacks with custom dosing. Calculate reconstitution to the unit. Log every dose, rotate sites automatically, and ask an AI advisor — privately on your iPhone.

Reconstitution, solved
From this... to this.
Stop second-guessing your draw. PepPal does the unit conversion for every vial, BAC volume, and syringe — to the unit.
Tuesday — BPC-157
10mg vial / 2mL water = 5mg per mL?
so 250mcg = 0.05mL ... no wait
250mcg / 5000mcg per mL = 0.05mL
0.05mL on a 100u syringe is...

Loved by every kind of user.

PeptidePal completely elevated my skin-focused protocol. Easily my most-used app.
- Clean UIClean UI and knows me well
“Super clean and surprisingly useful. First tracking app that actually feels built for peptides, not just a generic medication tracker. The protocol builder and reconstitution calculator are really straightforward.”
Colin Z.May 2026 - New to peptidesA must if you take peptides
“I am completely new to peptides and as I have been learning this app just made it so much easier and streamlined. Being able to read up on any peptide and then log it has been really helpful.”
Ke834Apr 2026 - Beginner-friendlyGreat way to break into peptides
“By far the most helpful app I have tried for easing into and tracking peptides. The protocol tracking and tutorials are really useful. Takes away a lot of the thinking.”
heckeroniandcheeseApr 2026 - Stack builderMy GH stack — finally simple
“CJC + Ipa twice a day, BPC for tendons, weekly tirz. PepPal handles the schedule and the math. I just open the app and follow the green checks.”
jakebMar 2026 - RecoveryTendon protocol on autopilot
“BPC near the affected site for 6 weeks, calendar tracks everything. The site rotation reminder alone is worth it.”

Is my data private?
Everything stays on-device by default. Optional iCloud sync uses your private iCloud — Blank Labs never sees your protocols, doses, or notes. No analytics on your health data.Is this medical advice?
No. PeptidePal is an educational and tracking tool. It surfaces published references and helps you stay consistent with a protocol you have decided to run with a qualified provider. Always verify dosing and reconstitution math with your clinician.Do you sell peptides?
No. PeptidePal does not sell, source, or recommend any vendor. We track and reference compounds — sourcing is your responsibility.Does it work without internet?
Yes. The protocol builder, calculator, calendar, and library all work fully offline. Only the AI advisor needs a connection.iPhone only?
Today, yes — PepPal is a native iOS app for iPhone, optimised for iOS 18 and later. iPad and Apple Watch companions are on the roadmap.How accurate is the reconstitution calculator?
It is pure mathematical conversion (mg / mL / units / mcg). It does not invent dosing — you provide the four inputs (vial, BAC water, desired dose, syringe size) and PepPal returns the exact draw. Always sanity-check before injecting.Can I import an existing protocol?
You can pick a curated stack (Wolverine, GH Stack, CLO, GLO) and customise from there, or build one from scratch. Bulk import from CSV is on the roadmap.
