Well, Master of ceremonies is something for sure.
I did find this online just for the hell of it...
GHK-CU -Sublingual/Oral Mucosa Absorption:
GHK-Cu is a small tripeptide (~340 Da without copper; complex is still compact), and the sublingual area has thin epithelium + rich blood vessels, allowing direct bloodstream entry and bypassing heavy first-pass liver metabolism (unlike swallowing pills). This route is used for many peptides/supplements to improve bioavailability over plain oral ingestion.
- Sources confirm sublingual is theoretically suitable due to molecular size and mucosal permeability.
- Troches (cheek/gum placement) are similar—some clinics describe them as providing moderate systemic availability by absorbing through oral mucosa while minimizing GI breakdown.
