Description

Rather than acting on the central nervous system, it works directly at the enzyme level inside cells

Like B12 shots, the nasal spray gets vitamin B12 directly into your bloodstream (via the nostrils), bypassing your digestive system

It carries two defining structural modifications: an N-terminal acetyl group and a bulky lipophilic C-terminal adamantane (diamondoid) group, the motif characteristic of Peptide 021
