How to Track a 5 On / 2 Off Peptide Cycling Schedule
The cycling pattern that breaks every reminder app
5 min readQuick Answer:
5 on / 2 off means inject for 5 consecutive days, then rest for 2 days. That's a 7-day cycle. Track by cycle day (Day 1 through Day 7), not by calendar day. Days 1-5 are ON, Days 6-7 are OFF. Repeat.
The Pattern
| Cycle Day | Status | Example (Mon start) |
|---|---|---|
| Day 1 | ON | Monday |
| Day 2 | ON | Tuesday |
| Day 3 | ON | Wednesday |
| Day 4 | ON | Thursday |
| Day 5 | ON | Friday |
| Day 6 | OFF | Saturday |
| Day 7 | OFF | Sunday |

Set the pattern once. It tracks which day you're on automatically.
Why Calendar Tracking Fails
If you always start on Monday, it aligns with the week. But:
- Miss a day? The pattern shifts. Now Day 1 is Tuesday. Your mental model breaks.
- Travel across time zones? Did the date change or not? Managing your peptide schedule while traveling adds another layer of confusion.
- Multiple cycling compounds? TB-500 on 5/2, another on 4 weeks on/2 off. The overlaps get impossible to manage by calendar.
How to Track It Correctly
- Mark your start date - This is Day 1, Cycle 1
- Count cycle days, not calendar days - “I'm on Day 4” not “It's Thursday”
- After Day 7, reset to Day 1 - New cycle begins automatically
- If you miss a day, adjust - Skip the missed day, continue the cycle count from where you are
Common 5/2 Protocols
- GH secretagogues (CJC-1295, Ipamorelin, Tesamorelin)
- TB-500 (some protocols)
- BPC-157 (less common, but used for receptor sensitivity)
The rationale: prevent receptor desensitization by giving the body 2 days without exogenous stimulation.
Stacking 5/2 with Other Schedules
Running CJC 5/2 alongside BPC daily and semaglutide weekly?
Monday: CJC + BPC. Tuesday: CJC + BPC. ... Saturday: BPC only (CJC off). Sunday: BPC + semaglutide (CJC off).
This is where “what's due today?” becomes impossible to answer from memory.
Other Cycling Patterns
- 4 weeks on / 2 weeks off - Common for longer cycles
- 10 on / 4 off - Used for some GH protocols
- Continuous - No break (healing peptides, short cycles)
- EOD - Every other day (different from cycling)
