- 4 weeks on / 2 weeks off
- Twice daily (12-hour intervals)
- 2 weeks minimum
- Yes. Sufficient turnover for baseline restoration
- Acute injury models, short-term tissue repair studies
- Standard protocol. Balances observation window with receptor reset
- 6 weeks on / 4 weeks off
- 4 weeks (full baseline)
- Yes. Extended reset allows complete receptor normalization
- Chronic stress models, extended observation periods
- Preferred for multi-cycle studies requiring consistent cycle-to-cycle response
- 8 weeks on / 1 week off
- 1 week (insufficient)
- No. Receptors remain partially downregulated
- Not recommended
- Produces diminishing returns after week 5; subsequent cycles show reduced efficacy
- Continuous (no washout)
- None
- No. Progressive receptor desensitization
- Observable effects plateau by week 6; ongoing administration wastes compound without additional benefit
- The table above reflects cycle structures we've reviewed across institutional peptide research protocols. The 4/2 and 6/4 structures preserve receptor sensitivity across multiple cycles, making them suitable for longitudinal studies. Continuous administration and insufficient washout structures consistently underperform after the first cycle.
