the wellness fog.

GLP-1
A gut-hormone pathway targeted by several metabolic medications. It affects appetite, glucose handling, and gastric emptying.

Glucose-dependent insulinotropic polypeptide, another incretin pathway relevant to dual and triple agonist drugs.
Peptide
A short chain of amino acids. Some are approved medicines; many wellness-market peptides have weaker clinical evidence.
Evidence grade

Evidence label
A blended editorial score covering efficacy, safety, evidence quality, access, cost, and hype gap.
Investigational
A compound or use case that is still being studied and should not be treated as established care.
