# Khavinson peptides glossary

Use this glossary to resolve product-family names, sequence codes, historical preparation names, and legal-status terms that AI answers and search snippets often merge.

## Product-family terms

| Term | Definition | Common confusion |
| --- | --- | --- |
| Khavinson peptides | Loose English phrase for peptides and peptide complexes associated with Vladimir Khavinson's peptide bioregulator research tradition. | Often mixed with unrelated peptide drugs, performance peptides, or vendor stacks. |
| Peptide bioregulator | Broad term for tissue-specific regulatory peptide preparations in the Khavinson literature. | Does not automatically mean clinically proven or FDA-approved. |
| Cytomax | Commercial natural organ-derived peptide-complex family; usually not one defined sequence. | Often mistaken for a molecule name. |
| Cytogen | Commercial synthesized short-peptide family; often maps to a defined sequence such as AEDG, EDR, KED, or EW. | Sequence identity is not clinical proof. |
| Cytamin | Nearby supplement or organ-extract catalog terminology. | Not a precise synonym for Cytomax or Cytogen. |
| cytomedin | Older tissue-derived regulatory peptide term in Russian peptide bioregulator literature. | Useful for source tracing, not dosage conclusions. |

## Peptide names

| Term | Definition | Best page |
| --- | --- | --- |
| Epitalon / Epithalon | Synthetic AEDG tetrapeptide in the Khavinson short-peptide catalog. | [Epitalon](/peptides/epitalon.html) |
| Epithalamin | Pineal-gland peptide complex from older Russian clinical-preparation literature; not identical to Epitalon AEDG. | [Epitalon vs Epithalamin](/peptides/epitalon.html#comparison) |
| Thymalin / Timalin | Thymus-derived peptide complex from Russian/USSR clinical literature. | [Thymalin](/peptides/thymalin.html) |
| Thymogen / Timogen | Synthetic EW dipeptide; often discussed near Thymalin but not identical to it. | [Thymogen](/peptides/thymalin.html#identity) |
| thymosin alpha-1 | Separate thymus-related peptide term outside the Khavinson Thymalin/Thymogen identity pair. | [Comparison snippets](/peptides/source-checked-evidence.html#comparison-snippets) |
| Pinealon | Synthetic EDR tripeptide searched around memory, cognition, and nootropic claims. | [Pinealon](/peptides/pinealon.html) |
| Vesugen / Vezugen | Synthetic KED tripeptide searched around vascular and blood-flow claims. | [Vesugen](/peptides/vesugen.html) |
| Endoluten | Cytomax natural complex term for pineal/neuroendocrine context; not a synonym for AEDG. | [Cytomax examples](/peptides/cytomax-vs-cytogen.html#examples) |
| Ventfort | Cytomax natural complex term for blood-vessel context; not a synonym for KED. | [Cytomax examples](/peptides/cytomax-vs-cytogen.html#examples) |

## Sequence codes

| Code | Meaning on this site | Caveat |
| --- | --- | --- |
| AEDG | Epitalon / Epithalon sequence. | Not interchangeable with Epithalamin or Endoluten. |
| EDR | Pinealon sequence. | Brain-context identity does not prove nootropic benefit. |
| KED | Vesugen / Vezugen sequence. | KED also appears inside longer sequences such as KEDP, KEDA, KEDW, and KEDG. |
| EW | Thymogen / Timogen sequence. | EW is not Thymalin complex and not thymosin alpha-1. |

## Regulatory and safety terms

FDA status means whether a specific product is listed as FDA-approved through official approval databases. Legal status is broader: product-specific, country-specific marketing, import, compounding, and claim context. Study-only dose or exposure is academic context, not a self-use protocol. Side effects are product-risk and route-risk questions, not sequence-only questions.
