NAD+ Dosage Calculator

Your 500 mg vial with 5 mL bacteriostatic water gives you 100 mg/mL. At 100 mg per dose, that's 1.0 mL (100 units on a U-100 insulin syringe), so one vial covers 5 doses. If you're running 250 mg doses, reconstitute with 2 mL instead: that gives 250 mg/mL, and each dose is 1.0 mL. Trying to pull 2.5 mL for a 250 mg dose from a standard 5 mL reconstitution is impractical for a single subcutaneous site. Inject slowly. Thirty to sixty seconds minimum. The sting is the number one complaint in every forum thread, and speed is almost always the cause. Warm the syringe in your palm for a minute before injecting. Morning dosing is the standard; some users report sleep disruption with evening administration. One thing most beginners miss: cloudiness or any visible precipitate means discard the vial. NAD+ degrades with heat and agitation. Add the water slowly down the vial wall and swirl gently. Never shake it.
