James Harper
Five ways to buy NAD⁺, and the very different amounts of evidence behind each one.
James Harper is a pen name used by a writer at NAD Picks. James compares delivery routes — subcutaneous injection, IV infusion, nasal spray, transdermal patch and oral precursor — on the only question that matters: whether there is published human evidence that the format delivers anything at all.
What they cover
- Routes of administration and bioavailability
- Subcutaneous and intravenous NAD⁺ protocols
- Intranasal and transdermal delivery
- Oral precursor absorption
- Compounded versus FDA-approved products
- Pharmacokinetics of coenzyme precursors
