What to Track During a Peptide Cycle
The metrics that actually matter for protocol optimization
5 min readQuick Answer:
Track per injection: compound, dose, time, injection site. Track daily: side effects, sleep quality, body weight. Track weekly: measurements, photos, subjective energy. Track per vial: reconstitution date, doses remaining, expiration. Track per cycle: start date, current phase, cycle day position.
Per-Injection Tracking
Every injection should log:
| Field | Why It Matters | Example |
|---|---|---|
| Compound | Confirms what was injected | BPC-157 |
| Dose | Correlates effects to dosage | 250mcg |
| Time | Identifies timing-dependent effects | 7:00 AM |
| Site | Prevents site overuse | Left abdomen upper |
| Units drawn | Catches measurement errors | 10 units (U-100) |
Most people try to track all of this in a spreadsheet — but spreadsheets are a single point of failure for protocol data.

Daily Observations
- Side effects - Nausea, headache, injection site reaction, appetite changes. Rate severity 1-5.
- Sleep quality - Hours slept, wake-ups, subjective restedness (1-5). GH secretagogues directly affect sleep.
- Energy level - Morning energy, afternoon crash, evening baseline. Trend over days.
- Appetite - Critical for GLP-1 compounds. Rate hunger on a 1-5 scale.
- Body weight - Same time daily, before food/water. Weekly average matters more than daily fluctuation.
Weekly Metrics
- Body measurements - Waist, hips, arms, thighs. Same conditions each time.
- Progress photos - Same lighting, angle, time of day. Compare across 4-week windows.
- Subjective assessment - Recovery speed, joint pain, mood, cognitive clarity.
- Protocol adherence - Missed doses, timing consistency, site rotation compliance. A cycle planning template helps define what “adherence” means before you start.
Inventory Tracking
Per vial, track:
- Reconstitution date (shelf life clock starts here)
- Water volume added (determines concentration)
- Doses remaining (decrements each injection)
- Expiration estimate (reconstitution date + stability window)
- Storage location (fridge position for multi-vial protocols)
With 3-4 compounds, you may have 4-6 active vials at different stages of depletion. Losing track means running out mid-cycle or injecting expired compounds.
Cycle Position Tracking
- Cycle day - Which day of your current cycle are you on? (Especially for 5/2 patterns)
- Titration phase - Which dose level? When does the next increase happen?
- Total cycle length - How many weeks completed out of planned protocol?
- Rest periods - When did the last off-cycle end? Are you in PCT?
What Most People Skip (and Regret)
- Baseline measurements - Without pre-cycle data, you can't quantify what changed
- Injection site history - Only noticed when lumps develop weeks later
- Exact timing consistency - “Morning” could be 6 AM or 10 AM. The 4-hour difference matters for some compounds.
- Side effect onset correlation - Did nausea start after the dose increase, or after adding the new compound? Without timestamps, you can't tell.
The Minimum Viable Log
If tracking everything feels overwhelming, start with just these 4 per injection:
- What compound and dose
- What time
- Which site
- Any immediate reaction (yes/no)
This alone prevents the most common problems: missed doses, site overuse, and inability to correlate side effects to dose changes.
