Early observations came from gastric studies, then attention spread to soft tissue under mechanical stress

Published work on intranasal peptide delivery (for insulin analogs, calcitonin, and oxytocin) demonstrates that bioavailability for this size class without enhancers is typically in the low single-digit percent range, though these data are from different peptides with different charge profiles

Exposure to heat can quickly degrade the vitamin, making it less effective

If your energy concerns are more about overall depletion, recovery, or cellular function, NAD+ may be worth discussing with a provider

What is GHK-Cu

The strong metal binding affinity of the imidazole ring on the histidine side chain brings oxidizing species close to the substrate methionine (6)
