How to Build a Peptide Stack in Protocol: Complete Protocol Builder Guide

Building a peptide protocol requires decisions at every step—template vs. custom, cycling strategies, titration schedules—and getting these wrong wastes compounds and delays results. Without a framework, users cobble together protocols from scattered notes, Reddit threads, or memory, leading to inconsistent tracking and lost data.

Protocol's protocol creation system turns these decisions into a structured, guided workflow. This walkthrough shows you how to build custom stacks whether you're running BPC-157 and TB-500 for recovery, GLP-1 titrations, TRT regimens, or multi-compound growth hormone stacks.

The creation flow starts with a choice: browse 15 pre-built templates or build custom from scratch. Templates are research-backed structures for common stacks—recovery, performance, anti-aging, fat loss. Most users start here, then customize to their exact compounds and doses.

You then select your tracking type. Peptide protocols for compounds like BPC-157, TB-500, and GLP-1. Supplement protocols for vitamins, minerals, and micronutrients running alongside peptides. Habit protocols for sleep, hydration, exercise, and behavioral variables that influence compound outcomes. All three types can run simultaneously in one unified dashboard.

Dose and route configuration lock in specifics: how much you're taking, via which route (subcutaneous, intramuscular, intranasal), and exactly when. You can set different doses for different days—critical for titration schedules where GLP-1 doses escalate weekly.

The schedule builder lets you define frequency (daily, every other day, weekly) and specific timing. For cycling protocols, you define on/off periods—5 days on, 2 days off, or 4 weeks on, 1 week off. This structure prevents accidental double-dosing and ensures you follow your intended protocol precisely.

Titration setup is where Protocol eliminates the most friction. Instead of manually adjusting doses weekly, you define your titration steps upfront—starting dose, increment, frequency—and Protocol manages the escalation automatically. This is essential for GLP-1 or any compound requiring dose progression over time.

The AI Research Assistant validates your stack before you activate it—checking compound interactions, suggesting dosing based on published data, and answering questions about your specific configuration. Once created, your protocol feeds directly into the Today screen and dose logging with no re-entry required.
