Peptide compounds, by family
Plain-English reference for the major peptide families. Sign in to AIx Core for the full picture — mechanism, citations, pathway diagrams, and one-tap add-to-protocol.
GLP-1 / incretin
5Metabolic + appetite regulators — GLP-1 alone or paired with GIP / glucagon for weight management and glucose control.
Growth hormone
5Growth-hormone-axis peptides — GHRH analogs and ghrelin-receptor secretagogues that nudge endogenous GH release.
Repair / recovery
6Tissue + gut repair peptides. Most data is animal-based; the human story is still being written.
Copper-coordinated
1Copper-coordinated peptides — best studied in skin for collagen and wound healing.
Metabolic fragment
2Metabolic fragments derived from larger hormones, designed for lipolysis without the parent molecule's side effects.
Cognitive
3Cognitive + mood peptides — mostly Russian-developed, mostly intranasal, mostly under-evidenced in Western trials.
Mitochondrial
3Mitochondrial-derived peptides — newer family centered on energy balance and longevity signalling.

Common questions
Is this medical advice?
No. Every entry is educational reference content. We don't prescribe, we don't recommend doses, and we don't replace a qualified clinician. Talk to your doctor before using any of these compounds.
What does "evidence tier" mean?
Each compound is tagged Human / Mixed / Animal / Weak based on the strongest published data behind it. Human means multiple clinical trials with statistically meaningful outcomes; Animal means the strongest evidence is rodent or in-vitro and the human story is still being written.
Is the library free?
Yes. Both the public overview here and the full AIx Core inside the app are free, included with every account. Sign up to see the full content.
