- Abdomen (periumbilical)
- 10–20mm
- Very easy. Full visibility, both hands free
- 12–15%
- Moderate. High injection frequency zone
- Best overall choice for most users. Consistent depth, easy rotation, proven absorption kinetics
- Anterior thigh
- 8–15mm
- Easy. Good visibility, stable position
- 14–18%
- Low. Large surface area for rotation
- Excellent secondary site. Slightly higher CV due to muscle proximity in lean individuals
- Posterior upper arm
- 8–12mm
- Difficult. Requires assistance or mirror
- 13–16%
- Low. Underutilized in most protocols
- Ideal third rotation point. Equivalent absorption but accessibility limits practical use
