You do not need to memorize a hundred compounds. You need the map. Once you can place any peptide into a family, the whole field stops feeling overwhelming. Researchers tend to group peptides by the biological systems their study focuses on.
| Family | What the research explores | Often-discussed examples |
|---|---|---|
| Metabolic / GLP | energy, metabolism, and glucose-signaling pathways | GLP-1, MOTS-c, AOD-9604 |
| Healing & recovery | tissue and gastrointestinal research models | BPC-157, TB-500, KPV |
| GH secretagogues | the growth-hormone signaling axis | CJC-1295, Ipamorelin, Sermorelin |
| Cosmetic & skin | skin, collagen, and pigment research | GHK-Cu, AHK-Cu, Melanotan |
| Longevity & cellular | aging and mitochondrial pathways | Epitalon, NAD+, SS-31 |
| Cognitive & neuro | neurological and behavioral research | Semax, Selank, DSIP |
| Sexual health | melanocortin-pathway research | PT-141 |
When you meet a new name, your first question is simply: which family? That single answer tells you roughly what kind of research it belongs to and what conversations surround it. A new compound stops being intimidating the moment you can place it.
These boundaries are useful, not rigid. Some compounds are studied across more than one family, and some research blends families deliberately. The map is a starting point for understanding, not a rulebook. As you read more, you will naturally refine it.
