The GI absorption, BBB permeation, P-gp substrate, cytochrome P450 enzyme inhibition/induction, skin permeation are critical for the oral activity of drug molecules and these properties can be predicted
Limitations include: Enzymatic and chemical degradation Poor membrane permeability Comparatively large molecular size When a peptide like epithalon is unmodified, bioavailability may be less than 1%

It is also vital to look for products that are third-party tested
Is peptide stacking based on science, or just hype
Lets be honest, the moment youre about to add liquid to a valuable peptide like Ipamorelin can feel like disarming a tiny, expensive bomb
