How Many Injection Sites Do You Need?
Site math for multi-injection protocols
4 min readQuick Answer:
Minimum 8 sites for daily injections, 12+ sites for twice-daily or multi-compound stacks. Each site needs 7-14 days rest between uses. Divide your weekly injection count by the recovery window to determine minimum sites needed.
The Formula
Example: 14 injections/week x (7 days recovery / 7) = 14 sites ideal, 8 sites minimum
Titer manages site rotation for any protocol.
8-16 sites tracked with recovery windows and overuse warnings.
Sites Needed by Protocol Frequency
| Protocol | Injections/Week | Min Sites | Ideal Sites |
|---|---|---|---|
| Once daily | 7 | 7-8 | 8-10 |
| Twice daily | 14 | 8 | 12-14 |
| 3x daily (multi-compound) | 21 | 10-12 | 14+ |
| Full stack (4+ compounds) | 22-28 | 12 | 14-16 |

Why Recovery Time Matters
- 7-day minimum - Tissue needs time to heal between punctures
- 14 days preferred - For daily injectors, gives tissue full recovery
- Under 7 days - Risk zone for lipohypertrophy (lumpy tissue, reduced absorption)
Real-World Example
Stack: BPC-157 twice daily + CJC nightly + semaglutide weekly = 22 injections/week
With 8 sites: each site used 2.75x/week (recovery: ~2.5 days). Risky.
With 12 sites: each site used 1.8x/week (recovery: ~4 days). Better.
At 22+ injections/week, 12 sites is the minimum for adequate recovery.
