- The table below compares the three primary CJC-1295 injection zones across key anatomical and practical variables. Use this to select the optimal site based on individual body composition, injection frequency, and prior experience with subcutaneous administration.
- Abdomen (2 inches lateral to navel)
- 1–2 cm in most adults
- Very high. No assistance needed
- Moderate. Steady 12–18 hour curve
- Low if midline avoided
- Every 4–6 weeks per specific spot
- Best first-choice site for most users. Highest margin for error, most forgiving anatomy, consistent absorption
- Outer thighs (mid-vastus lateralis)
- 0.8–1.5 cm depending on body composition
- High. Standing or seated access
- Slightly faster. 10–15 hour curve due to ambulatory blood flow
- Low if lateral zone targeted
- Every 4–6 weeks per leg
- Ideal secondary site for rotation or primary for individuals with abdominal scarring. Reliable and accessible
- Upper arms (posterior tricep region)
- 0.5–1 cm (thinner layer)
- Moderate. May require assistance or flexibility
- Moderate to fast. 10–14 hour curve
- Low in central tricep area, higher near elbow
- Every 4–6 weeks per arm
- Best used as part of 5-site rotation to minimize fibrosis. Less forgiving for technique errors but valuable for tissue distribution
