How to Track Peptides
Most people start tracking peptides after something goes wrong. A vial runs out mid-cycle. A syringe site gets sore. A dose gets double-logged.
This guide covers the complete system for tracking peptides from day one — whether you're running a single compound or a full stack.
Why Tracking Peptides Is Different
Tracking peptides is not the same as logging gym sessions or counting calories. The dose is measured in micrograms. The timing affects pharmacokinetics. The injection site affects tissue health. The vial has a 28-day expiration clock running from the moment you add BAC water.
A standard fitness tracker handles none of this. A spreadsheet handles the dose log but not the rotation, not the vial clock, not the multi-compound consolidated view.
Tracking peptides properly means tracking six things: dose logs, injection sites, vial details, protocol schedule, stack overview, and response data. The first three are the minimum.
The system below covers each. At each step, we show how Protocol's peptide tracker implements it — but the system works with any dedicated tool.
The Tracking System — Step by Step
Before You Reconstitute
Set up your protocol in writing
Write down every compound you're running: the name, dose in mcg, frequency, and cycle length. Do this before you order anything. A protocol written down is a protocol you can track. A protocol in your head is a protocol you're already approximating.
Include the vial size you're ordering and how much BAC water you plan to use. This determines your concentration — and your concentration determines every draw unit calculation that follows.
At Reconstitution
Log the vial details the moment you mix
The reconstitution date is the most important date in your tracking system. A peptide vial reconstituted in bacteriostatic water is stable for 28–30 days refrigerated. Past that, potency degrades — silently, with no visible indicator.
Record: compound name, vial size in mg, BAC water volume added, resulting concentration in mcg/mL, reconstitution date, batch number if available, and vendor. Calculate the number of doses the vial contains at your target dose. This is your vial's lifespan.
First Injection
Log the dose before you put the cap back on the syringe
Log while the syringe is still in your hand. Not after. Not when you remember later. The friction of pulling out a phone after an injection is exactly when logs stop happening.
Record: compound, dose in mcg, draw units on the syringe, time of injection, and injection site zone. The draw units are what you actually measured — log that, not just the target dose.
Daily Practice
Use injection site rotation as a non-negotiable
Repeated subcutaneous injection in the same site builds scar tissue — lipohypertrophy — that reduces absorption and creates visible nodules. It doesn't announce itself until it's already a problem. The fix is systematic rotation from the first injection, not after you notice the issue.
Eight standard zones: four abdominal quadrants (upper-left, upper-right, lower-left, lower-right), two outer thighs, two deltoids. Daily injections return to any given zone after 8 days. Twice-daily injections should split between distant zones per session.
Multi-Compound Stacks
Build one unified daily view — not a log per compound
Tracking each compound in a separate notebook, note, or app is how double-doses happen. You log BPC-157 in one place, check TB-500 in another, and forget which day Ipamorelin falls on.
A unified daily view shows every compound due today across your entire stack, in a single checklist. When everything is in one place, checking takes 10 seconds. When it's scattered, it takes a minute — and that's the minute most people skip.
Reviewing Progress
Review your logs weekly, not just when something feels off
A dose log reviewed only when something goes wrong is a retrospective tool. A log reviewed weekly becomes a predictive one. You catch the vial that's running low before day 14, not on day 14.
Weekly: check vial status (doses remaining, days since reconstitution). Check injection site distribution — are you actually rotating? Review adherence: did you hit your target doses on your target schedule? Anything that looks off is easier to correct before the cycle ends than after.
Tracking Common Peptide Compounds
The system above applies to all peptides. Each compound has specific considerations that affect how you set it up.
BPC-157
Research profile →Injection site matters for mechanism
BPC-157 can be injected locally (near injury) or systemically (abdomen). Log which approach you're using — the mechanism is different, and so is the expected response. Most protocols run 250–500mcg twice daily for 4–8 weeks.
TB-500
Research profile →Systemic injection — site matters less than rotation
TB-500 works through systemic actin regulation, not local application. Inject anywhere and rotate normally. Track loading vs. maintenance phases separately — 2.5–5mg twice weekly loading, 2.5mg maintenance. Often stacked with BPC-157.
Semaglutide / GLP-1
Research profile →Weekly dosing with escalating titration
GLP-1 peptides follow a strict titration schedule. Log each weekly dose with the exact amount and week number. Titration errors — skipping a step, or titrating up too fast — produce stronger GI side effects. The titration history is the most important data to preserve.
Ipamorelin / CJC-1295
Research profile →Timing relative to sleep and meals is part of the data
GH secretagogues work best timed to sleep onset. Log injection time relative to lights out. Blunting from food intake affects the GH pulse — note whether the injection was fasted. The timing data makes a meaningful difference for reading results.
