Practical writing on peptide tracking, protocols, and what we're learning building Peptra.

Tracking fundamentals

How to Track Peptide Doses Properly: A Practical Guide

Clean dose logs are the foundation of any serious peptide protocol. Here's the framework Peptra uses — and why most spreadsheets break down within two weeks.

Protocol

Peptide Cycle Length: When to Stop, When to Continue

Most peptides have a recommended cycle window — but the protocols you find online conflict constantly. We break down the published research on cycle length for the 12 most common peptides.

Practice

Injection Site Rotation: Why It Matters and How Peptra Handles It

Repeated injections in the same site cause lipohypertrophy, scar tissue, and absorption problems. Here's the rotation pattern most clinicians recommend, and how to actually stick to it.

Stacks

Stacking BPC-157 and TB-500: Tracking the Combination

BPC-157 + TB-500 is the most common recovery stack in the peptide space. We cover the protocol logic, why timing matters, and how to log both compounds without losing data integrity.

GLP-1

GLP-1 Titration Schedule: Semaglutide vs. Tirzepatide Compared

Both semaglutide and tirzepatide require strict titration. We compare the manufacturer schedules, common deviations, and how to track weight + side-effect response over months.

About Peptra

Why We Built Peptra Instead of Using a Spreadsheet

Spreadsheets work for the first month. Then dose schedules drift, sites stop rotating, and you're guessing about cycle endings. Here's why dedicated tracking matters.

Tracking fundamentals

Peptide Reconstitution Calculator: How to Do the Math Correctly

Reconstituting peptides is straightforward math, but it's where the most dose errors happen. Here's the formula, common mistakes, and a built-in calculator that does it for you.

Practice

How to Inject Peptides: A Safety Primer for First-Timers

Subcutaneous injection technique, syringe selection, sterile practice, and what nobody tells you about needle disposal. Not medical advice — but a clear walkthrough of the process.

Protocol

When to Stop a BPC-157 Cycle: The Signs to Watch For

Most BPC-157 cycles are 4-8 weeks, but there are specific markers — both subjective and objective — that indicate it's time to pause. We cover them.

Stacks

Stacking Ipamorelin and CJC-1295: The GH Releaser Combo

The ipamorelin + CJC-1295 stack is the second most common in the peptide space. Here's how the two compounds complement each other and how to track both without losing the cadence.

GLP-1

Tirzepatide vs Semaglutide: Titration Speed Compared

Both compounds require titration but at different speeds and different ladders. Side-by-side comparison of weeks-to-target-dose, side effect profiles, and how Peptra handles each.
