Peptides are typically shipped in a lyophilized (freeze-dried) state for a reason
A defining characteristic studied in research is its unusual stability: it remains intact in human gastric juice for more than 24 hours, distinguishing it from most peptides, which degrade rapidly

IV administration bypasses the digestive system, which can degrade NAD+ when taken orally
The full mass scan was acquired from m/z 350 to 1550 with resolution 120,000 at a target of 2e5 ions, and the MS/MS spectra were obtained in a data dependent acquisition in the top speed mode with higher-energy collision dissociation (target 5e4 ions, max ion injection time 100 ms, isolation window 1.6 m/z , normalized collision energy 25%)
Our fastest drip which is deliberately given in 10-15 minutes to achieve a large serum spike
