Taxorest
Bronchial Extract Bioregulator · Bronchial Cytomax · Таксорест
Taxorest is the Cytomax bronchial-mucosa complex on the official 21-SKU list. Bronchogen and Chonluten are the airway cytogens. Honluten is an extra lung-extract product in some catalogs - adjacent, not a 22nd silent Cytomax on the e-peptide poster.

How it works
Taxorest (A-19) is a Cytomax natural polypeptide extract from the bronchial mucosa of young calves, targeting human bronchial epithelial cells, Clara cells, and type II pneumocytes to restore age-silenced gene expression governing mucociliary clearance, surfactant synthesis, and bronchial anti-inflammatory signaling. The lungs undergo progressive structural aging: mucociliary clearance slows (reducing the ability to expel inhaled particles), alveolar surface area declines by 4 m² per decade after age 30, and type II pneumocyte reserve capacity for surfactant production diminishes, contributing to declining FEV1 and increased respiratory infection susceptibility.
Taxorest delivers short peptide signals (<10 kDa) from bovine bronchial tissue. These peptides penetrate bronchial cell nuclei to reactivate transcription of genes encoding: CFTR (cystic fibrosis transmembrane conductance regulator, critical for airway surface liquid homeostasis), MUC5AC and MUC5B (airway mucins essential for the gel-on-brush mucociliary defense system), surfactant protein D (SP-D, which neutralizes inhaled pathogens), and IL-10 (bronchial anti-inflammatory cytokine). This is a tissue restoration mechanism - not a bronchodilator or anti-inflammatory drug.
In Khavinson's protocols, Taxorest (A-19, bronchial) is often paired with Chelohart (A-14, heart) and Ventfort (A-3, blood vessels) for the cardiovascular-pulmonary system bundle, since pulmonary vascular resistance and gas exchange efficiency are directly coupled to cardiac output demands.

Canonical 41Used in bioregulator stacks
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
Airway peptide bioregulation splits mucosa (Taxorest) from lung parenchyma (Honluten in some lines) from bronchial synthetics (Bronchogen, Chonluten/EDG). The official Cytomed 21 includes Taxorest, not Honluten. We still cover Honluten because US vendors sell it.
This is not a LABA, not inhaled corticosteroid, not a CFTR modulator. Smoking-related disease still starts with cessation.
Caveats
Airway Cytomax is not a US dietary-supplement monograph and not a drug. The tissue-extract model means lot-to-lot composition is a fingerprint, not a single CAS number. English-language “V2” bottles that claim more peptide diversity are a later commercial layer (mass-spec marketing from specific brands) - they are not Khavinson’s 1990s papers. Animal-source capsules are inappropriate if the reader has a religious or allergy constraint on the source species. None of this replaces care for the actual organ disease.

Administration
Taxorest: Not a research vial vs Oral capsule
- The defined-sequence vial in this aisle is the cytogen pair (Bronchogen and Chonluten (airway cytogens)), a different SKU.
- There is no pharmaceutical-extract SKU that is this capsule in a syringe.
- Reconstitute Bronchogen or Chonluten if you bought those cytogens. Confirm the bottle: Taxorest capsule vs Chonluten (EDG) vs Honluten extract. One-letter collisions are a live search disaster.
- Taxorest is an oral capsule complex. It is not a 5 mg lyophilized research vial.
- Inventing recon math for a zero-mg Cytomax vial is how people inject the wrong product.
- Not an official Cytomed sublingual tablet, IM ampoule, or eye drop either.
- Official form for Taxorest: swallow the capsule with water. No reconstitution step and no 5 mg cake.
- Bronchial-mucosa Cytomax (Cytomed A-19) on the official 21. Honluten is a catalog lung SKU, not a 22nd silent Cytomax on the e-peptide poster.
- Course-based (10–30 days, a few times a year in manufacturer folklore), not a daily forever drug.
- Bronchial mucosa Cytomax is a peptide mixture / lot fingerprint, not a single CAS. English “V2” bottles are a later commercial layer, not a Khavinson RCT.
- Russian school literature is not an FDA organ-disease label.
- Third-party lingual SKUs exist in the wild. We do not claim sublingual as the official Cytomed Cytomax form.
