How it works

Chonluten (Glu-Asp-Gly) is a tripeptide bioregulator targeting the lungs and gastric mucosa. It primarily acts on the respiratory epithelial cells to reduce inflammation, improve oxygen transfer capacity, and support lung tissue regeneration. It is frequently utilized in protocols for respiratory aging, post-infection recovery, and environmental toxin (e.g., smoking) damage.

Manufacturer-style organ combinations - not FDA protocols. Every name is a live leaf.

The Khavinson school

Vladimir Khatskelevich Khavinson (1946–2024) spent five decades at what became the St. Petersburg Institute of Bioregulation and Gerontology arguing a simple, stubborn idea: aging is, in part, a failure of tissue-specific peptide signals, and those signals can be restored. The first products were not “peptides” in the Instagram sense. They were Cytamins - polypeptide fractions isolated from a named organ of young animals. Later commercial refinements of those fractions are sold as Cytomaxes (Cytomed / NPCRIZ): still mixtures, still oral capsules, still defined by the source organ rather than a single sequence. When the group identified short active motifs inside those mixtures, they synthesized them as Cytogens - di-, tri-, and tetrapeptides with a one-letter code (KE, AEDG, KED, EDR, KEDP, and so on).

That three-layer stack is the whole map. Cytamin / pharmaceutical extracts (Thymalin, Epithalamin, Cortexin, Retinalamin, Prostatilen) are the clinic-era injectables registered in the former Soviet pharmacopeia. Cytomaxes are the capsule complexes Cytomed still lists as a 21-SKU organ line. Cytogens are the defined synthetics. English-language educators, including Brenden Henry’s public writing at Peptide Science Institute, add a further commercial distinction - later analog SKUs (N-acetyl, amidate, “V2” complexes) sold as more stable or more diverse than the original Cytomed lots. That last layer is a product taxonomy, not a Khavinson paper. We describe it so readers are not gaslit by three bottles with the same organ name. We do not reproduce paid Peptide Mastery protocols, Precision Cell Method language, or anyone else’s course IP.

Full Cytamin → Cytomax → Cytogen map, literature limits, and how we counted 41

The mechanism Khavinson published is epigenetic, not receptor-agonist in the GLP-1 sense. Short peptides are claimed to enter nuclei, interact with DNA/histones, and reopen tissue-specific transcription that condensed with age (heterochromatin → euchromatin). Reviews in the Bulletin of Experimental Biology and Medicine and Neuroendocrinology Letters (PMID 14523363, 15677927, 23888677) are the citable core. Complementary GI pharmacology is not mystical: di- and tripeptides are PEPT1/LAT substrates, which is why oral capsules are even a conversation. What is not established in Western Phase 3 programs is organ-by-organ disease treatment, telomere reversal as a clinical endpoint, or the manufacturer claim that Cytomax is “a third stronger” than Cytogen. Those are NPCRIZ marketing sentences.

Khavinson’s group published hundreds of papers, many in Russian, many in the same journal family. That is a real literature. It is also a literature with limited independent Western replication, small n, and a habit of using one review PMID as a stamp on every organ. On this site a leaf earns its organ story, its Cytomax↔Cytogen pair, its sequence if it has one, and an honest sentence about what has not been shown. Reconstitution math belongs on cytogens sold as vials. Cytomax capsules do not get a fake 5 mg vial.

The 41 we treat as canonical are the 21 Cytomaxes on the public e-peptide/Cytomed list, the 12 Cytogens on that same commercial line (including Vesilut, which Western catalogs often drop), plus eight historically load-bearing molecules that sit beside the capsule SKUs: Epitalon, Vilon, Thymogen, Livagen, Cortagen, Prostamax, Thymalin, and Epithalamin. Honluten, Cortexin, Retinalamin, Prostatilen, Thymulin, N-acetyl-epitalon-amidate, Pinalex, and the GPL Man / GPL Femme kits are covered as adjacent - same school or same storefront, not padded into a fake 41.

Public English-language teaching (including Brenden Henry at peptidescienceinstitute.com) is cited as context, not copied. Paid Peptide Mastery / Peptide Salvation text stays theirs.

History of this molecule

NPCRIZ lists both Chonluten and Bronchogen on the cytogen poster - lungs/bronchi versus a more bronchial-specific tetrapeptide (AEDL). Taxorest is the official Cytomax for bronchial mucosa. Honluten is a separate extract SKU in Western menus and is not on the e-peptide 21.

EDG is mucosa/surfactant-adjacent in the school’s telling. It is not a LABA. It is not nintedanib. Post-viral fibrosis YouTube protocols are not a substitute for pulmonary rehab and actual imaging.

Caveats

A defined sequence is not an FDA indication. Airway cytogens sit in a Russian experimental-gerontology literature with limited Western replication. “Oral bioavailability because PEPT1” is real peptide-transport biology; it is not proof this SKU treats the organ disease. Gray-market identity is a live problem - HPLC is the only way to know the vial is the sequence on the label. Confirm the label is Chonluten not Honluten.

Dosing

PhaseDoseFrequencyNotes
Khavinson Protocol1–2 capsules/day or 1–2 mg SCDaily for 10–30 day courses, 1-2x per yearLung/respiratory bioregulator. Often used strategically with Bronchogen.

Administration

Route / form
Two real SKUs: Cytomed oral capsules (swallowed) or a lyophilized research vial reconstituted for subcutaneous injection. Nobody manufactures these as sublingual tablets.
Timing
Capsules: morning, about 30 minutes before meals. Research vial (SubQ): food does not change the injection.
Empty stomach?
Capsules: yes - Swallow on an empty stomach, about 30 minutes before meals. Reconstituted vial (SubQ): food does not change the injection. Cytomed boxes sometimes print “with food” because they are labeled as supplements; the manufacturer user-guide preference is before meals.

Chonluten: oral vs SubQ

Cytomed oral capsule
Bioavailability
No published human F% for this SKU. Di- and tripeptides can ride PEPT1/LAT; that is transporter biology, not proof the capsule treats the named organ. Cytomed cytogen capsules are swallowed.
Dose note
Chonluten Cytomed cytogen capsules: 1–2 capsules/day, typically 10–30 day courses. No reconstitution. Swallow; do not melt under the tongue. Swallowed with water. Morning, about 30 minutes before meals, is manufacturer user-guide folklore. Cytomed boxes sometimes print “with food” because they are labeled as supplements. That is not a published absorption RCT for this SKU. Pair: Taxorest is the bronchial Cytomax. Bronchogen (AEDL) is the other airway cytogen. Honluten is a lung-extract catalog SKU, not this tripeptide.
Advantages
  • Official Cytomed cytogen SKU is a swallowed capsule. No BAC water, no syringe.
  • Matches how Cytomed ships the poster line.
  • Nobody manufactures this as a sublingual tablet.
Considerations
  • Capsule milligrams are not 1–2 mg SC. Do not convert a research-vial protocol into capsule counts by arithmetic theater.
  • Empty-stomach timing is user-guide folklore plus PEPT1 logic, not a cited human PK study for this SKU.
  • Chonluten is EDG, lungs and bronchi. The Honluten one-letter collision is how people buy the extract bottle. Two airway cytogens (EDG vs AEDL) is manufacturer reality, not a duplicate SKU.
  • Confirm the label is Chonluten, not Honluten, before you swallow a 10–30 day course.
Research vial SubQ
Bioavailability
No published human PK curve for this cytogen. Research-chem SubQ is the gray-market route. Class estimate is minutes-to-hours, not a depot ester.
Dose note
Research lyophilized vial: reconstitute with bacteriostatic water, sterile technique, SubQ. Class pattern is about 1–2 mg daily for on the order of 10 days, not a 12-week GLP-1 titration. Food does not change the injection. Do not convert Cytomed capsule counts into vial milligrams. Pair: Taxorest is the bronchial Cytomax. Bronchogen (AEDL) is the other airway cytogen. Honluten is a lung-extract catalog SKU, not this tripeptide.
Advantages
  • Vial math is checkable if the COA matches the sequence on the label.
  • Food timing is irrelevant for SubQ.
  • Short pulsed courses match how the school used defined synthetics.
Considerations
  • Gray-market identity: HPLC is the only way to know the cake is EDG (Glu-Asp-Gly).
  • Not a Western Phase 3. Russian experimental-gerontology literature is real and concentrated.
  • Not a sublingual tablet and not a Cytomax complex.
  • Chonluten is EDG, lungs and bronchi. The Honluten one-letter collision is how people buy the extract bottle. Two airway cytogens (EDG vs AEDL) is manufacturer reality, not a duplicate SKU.
  • Not a LABA, not nintedanib. Post-viral fibrosis YouTube protocols are not pulmonary rehab.
Recommendation: Two SKUs. Swallow Cytomed Chonluten capsules (no recon, not sublingual) or BAC-reconstitute a research vial for SubQ at the 1–2 mg / ~10-day class pattern. Food does not change the shot. Pair: Taxorest is the bronchial Cytomax. Bronchogen (AEDL) is the other airway cytogen. Honluten is a lung-extract catalog SKU, not this tripeptide. Chonluten is EDG, lungs and bronchi. The Honluten one-letter collision is how people buy the extract bottle. Two airway cytogens (EDG vs AEDL) is manufacturer reality, not a duplicate SKU. Russian literature is real; Western Phase 3 is not. Keep prescribed airway drugs. COPD is not a cytogen label.

Limits of current evidence

  • A defined sequence is not an FDA indication.
  • Gray-market identity is a live problem. HPLC beats a blog table.
  • Do not paste a sibling cytogen’s papers onto this SKU.
  • This site will not treat the named organ disease from a peptide page.

Verdict

Chonluten is the synthetic EDG cytogen for Lungs and bronchi. Khavinson’s group published in this family. That is a concentrated literature, not a Western Phase 3. Capsules and vials are different SKUs.

Interactions & Contraindications

This site will not treat lung disease from a peptide page.

Synergies & Common Stacks

Two respiratory cytogens. Complementary marketing is not a combo RCT.
