Knowledge before hype.
Peptides explained clearly.

These entries focus on structural classification, origin and general research domains without discussing dosing, administration or clinical guidance.

Entries highlight receptor families, molecular class and general research contexts such as mitochondrial dynamics or energy homeostasis.

The focus here is on receptor targets (GHRH, ghrelin, IGF-1) and structural class, without touching dosing paradigms or therapeutic protocols.

Definitions emphasize peptide class and general neurobiological or chronobiological research contexts, not subjective effects or protocols.

Entries describe structural class and receptor families such as melanocortin receptors, avoiding claims around cosmetic or behavioral outcomes.
