Your NAD+ injection order will arrive with the following: one (1) 5ml vial of NAD+ injectable solution (200 mg/ml concentration), syringes, and needles for administration.
Each 0.1ml (10 units) of solution equals 20mg of NAD+. As such, 0.1ml (10 Units) = 20mg NAD+, 0.25ml (25 Units) = 50mg of NAD+, and 0.5ml (50 Units) = 100mg of NAD+.
The injection is administered into a fatty layer of skin, such as: back of arm, abdomen, or flank/lumbar region.
You will draw up the prescribed amount with the provided insulin needle and syringe, then inject subcutaneously. The recommended dose of general health is to start out with 0.1ml and, as desired, slowly ramp up to 0.5ml (100mg) up to 3x per week. Each 0.1ml (10 units) of solution equals 20mg of NAD+.
