- Abdomen (lateral)
- 1.5–3.0 cm
- 2/5
- Moderate (peaks 45–90 min)
- Easy. Visual access, two hands free
- Moderate if overused
- Best for consistent rotation. Ample surface area, forgiving anatomy
- Anterior Thigh
- 2.0–4.0 cm
- 1/5
- Moderate-slow (peaks 60–120 min)
- Moderate. Requires sitting, single-hand technique
- Low due to large surface area
- Excellent for higher-volume injections, underused by most protocols
- Deltoid (posterior)
- 0.5–1.5 cm
- 3/5
- Moderate-fast (peaks 30–75 min)
- Difficult. Requires mirror or contralateral hand reach
- High if depth misjudged
- Use sparingly. Limited subcutaneous depth increases risk of IM injection
- Upper Buttocks (ventrogluteal)
- 2.5–5.0 cm
- Slow (peaks 90–150 min)
- Difficult. Requires mirror, awkward angle
- Low
- Reserve for expanded rotations or higher-volume protocols
- Absorption speed correlates inversely with subcutaneous fat thickness and local blood flow. The abdomen and thigh offer the most consistent kinetics for NAD+. Neither too fast (which can cause transient flushing in sensitive individuals) nor too slow (which delays therapeutic effect).
