Peptra logs doses, schedules cycles, rotates injection sites, and tracks the markers that matter — for BPC-157, semaglutide, tirzepatide, and 12+ more peptides. Designed by people who actually run protocols.
Peptide protocols span weeks of doses, multiple injection sites, dose titrations, and stack timing. After two months in a spreadsheet you're guessing — about cycle endings, last injection site, and how you actually felt.
Every dose timestamped with route, site (with anatomical map), and reconstitution math. Auto-rotates to the next least-used site.
Pre-loaded titration schedules for GLP-1s. Custom cycles for stacks. Reminder windows that respect your meal timing.
Weight, sleep score, recovery rating, side effects. Charts that show response curves over your protocol, not just one data point.
Tell Peptra your vial mg and BAC water volume — it tells you the units to draw for any dose. Stops the calculator-on-bathroom-counter ritual.
Weekly AI-generated summary: cycle progress, missed doses, side-effect patterns, suggestions to discuss with your clinician.
Your data lives locally. Optional encrypted iCloud sync, optional anonymous cohort export for research. No accounts required.
From recovery (BPC-157, TB-500) to GLP-1s (semaglutide, tirzepatide), GH secretagogues (ipamorelin, CJC-1295), and longevity (epitalon, MOTS-c).

Open the calculator →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.
