- Abdomen (4 quadrants)
- 1.5–3.0 cm in most users
- Excellent. Self-administered without mirror
- Highly consistent. Minimal depth variation
- 16–20 sites (4 per quadrant)
- Optimal primary site for daily rotation. Largest usable area, best absorption predictability, minimal nerve/vessel density
- Outer Thigh
- 0.8–2.0 cm (depth varies with BMI)
- Good. Requires sitting position
- Moderate. Depth inconsistency affects absorption rate
- 8–12 sites (4 per thigh)
- Best backup site when abdominal sites need extended recovery. Less fat depth means higher intramuscular injection risk in lean users
- Upper Buttock (Dorsal Gluteal)
- 2.0–4.0 cm
- Poor. Requires mirror or partner assistance
- Good. Deep subcutaneous layer
- 6–8 sites
- Secondary option for users with limited abdominal access due to prior surgery or lipodystrophy. Difficult self-administration limits practicality
- Outer Upper Arm
- 0.5–1.2 cm (minimal in most users)
- Moderate. Non-dominant arm only
- Poor. High intramuscular injection risk
- 2–4 sites
- Not recommended for daily peptide injections. Insufficient subcutaneous fat in most adults, high risk of deltoid muscle penetration
