Practical writing on peptide tracking, protocols, and what we're learning building Peptra.
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.
ProtocolMost 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.
PracticeRepeated 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.
StacksBPC-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-1Both semaglutide and tirzepatide require strict titration. We compare the manufacturer schedules, common deviations, and how to track weight + side-effect response over months.
About PeptraSpreadsheets 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 fundamentalsReconstituting 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.
PracticeSubcutaneous injection technique, syringe selection, sterile practice, and what nobody tells you about needle disposal. Not medical advice — but a clear walkthrough of the process.
ProtocolMost 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.
StacksThe 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-1Both 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.
