Cardiogen
A synthetic short peptide bioregulator (commonly cited as the tripeptide Ala-Glu-Asp) from the Khavinson program, positioned as a myocardial tissue-specific regulator and studied in rodent cardiac and tumor models for age-related cardiac function decline.
What is Cardiogen?
Cardiogen is a synthetic short peptide bioregulator from the Khavinson program at the St. Petersburg Institute of Bioregulation and Gerontology, positioned in the catalog as the myocardial / heart-muscle tissue-specific entry. It is most commonly cited as a tripeptide with the sequence Ala-Glu-Asp (AED), paralleling the naming convention of other Khavinson tissue-targeted short peptides (Vesugen / KED for vasculature, Livagen / KEDA for liver and immune, Cortagen / AEDP for cortex). The underlying claim is that Cardiogen selectively interacts with cardiac tissue and modulates gene expression patterns in aging cardiomyocytes, with proposed applications in age-related cardiac function decline, post-infarct recovery, and heart-muscle regeneration. The PubMed-indexed evidence specific to Cardiogen is small — only a handful of Khavinson-group or Russian-collaborator studies in rodent myocardial and tumor-modifying models — and independent Western replication is essentially absent. Reliable confirmation of the exact amino acid sequence in peer-reviewed literature is limited; the AED attribution comes primarily from Khavinson-aligned sources and commercial product listings rather than from a definitive published structural paper, which is itself part of the honest caveat on this peptide.
What Cardiogen Is Investigated For
Cardiogen is studied within the Khavinson bioregulator framework as the heart-tissue counterpart to the other organ-specific short peptides (Livagen for liver, Vesugen for vasculature, Cortagen for cortex) and is discussed for age-related cardiac function decline, post-infarct recovery, and cardiomyocyte support. The available peer-reviewed Cardiogen-specific evidence is small and concentrated in Russian-language or Russian-authored journals: an organotypic tissue-culture study showing Cardiogen stimulated cell proliferation in myocardial explants from old rats more strongly than in young rats, and a tumor-modifying study in senescent rats bearing M-1 sarcoma, plus the broader tissue-specificity literature that groups Cardiogen with other Khavinson short peptides. There are no PubMed-indexed randomized controlled trials in humans for any cardiovascular indication, no independent Western preclinical replication of the myocardial-regeneration claim, and no characterized human pharmacokinetics. Vendor and forum claims around post-infarct recovery, heart failure, or cardiac regeneration in humans significantly exceed what that evidence base can independently support. Cardiogen is sold as a research chemical or as a Russian-market dietary peptide complex (Peptides.ru / Khavinson Peptides line) depending on the channel, and has no FDA approval, no EMA approval, and no formal registration as a Western prescription medicine.
History & Discovery
Cardiogen is one of the organ-specific short peptide entries in the Khavinson bioregulator program at the St. Petersburg Institute of Bioregulation and Gerontology, led by Vladimir Khavinson. The program's methodology, laid out across decades of Russian-language publications and a smaller set of English-language reviews, was to take tissue-specific complex extracts from animal organs (thymus, pineal, liver, prostate, heart, etc.), fractionate them to identify putatively active short-peptide components, and then synthesize chemically defined short peptides claimed to reproduce the tissue-targeting effect. Cardiogen occupies the myocardial slot in this catalog — sometimes described as the synthesized counterpart of the older natural-extract preparation derived from cattle heart tissue — and is most commonly identified as the tripeptide Ala-Glu-Asp (AED), paralleling the short-sequence naming convention used for its sibling peptides. The PubMed-indexed literature on Cardiogen specifically is modest compared to flagship Khavinson entries like Epithalon or Thymalin: a handful of organotypic tissue-culture studies, a senescent-rat tumor-modifying study, and inclusion in broader tissue-specificity reviews. Independent Western preclinical replication by cardiology or structural-biology laboratories has not materialized, and there is no PubMed-indexed human clinical trial for Cardiogen in any cardiovascular indication. The peptide reaches Western users almost exclusively through research-chemical lyophilized vials labeled 'not for human use' or through the Russian-market Khavinson Peptides / Peptides.ru oral capsule line marketed as a dietary peptide complex — neither of which represents validated therapeutic use, and neither of which is regulated to the evidence standard that would normally accompany a drug for a cardiovascular indication.
How It Works
Cardiogen is proposed to act as a 'tissue-specific' short peptide that selectively interacts with heart-muscle cells and nudges their gene expression toward a healthier, younger pattern. The idea is that as the heart ages, genes involved in cardiomyocyte maintenance and repair become progressively silenced; a short peptide with the right sequence is claimed to bind DNA regulatory regions and reactivate some of those programs, supporting cell proliferation and survival in aged myocardium. This is the same general framework the Khavinson program applies to all its tissue-targeted short peptides — the specific details for cardiac tissue are much less established than for the better-studied members of the catalog.
Within the Khavinson bioregulator framework, Cardiogen (Ala-Glu-Asp) is proposed to act through direct interaction with DNA regulatory regions and histone proteins in cardiomyocytes, modulating chromatin accessibility and gene expression patterns in aging heart tissue. In an organotypic tissue-culture study (Chalisova et al., Adv Gerontol 2009), Cardiogen stimulated cell proliferation in myocardial explants from old rats substantially more than in explants from young animals, a pattern the Khavinson group interprets as evidence of age-dependent reactivation of silenced gene programs. The broader tissue-specificity literature (Zakutskii et al., Adv Gerontol 2006) groups Cardiogen with Livagen, Vesugen, Cortagen, and others, claiming each short peptide preferentially activates cells of its named target tissue through sequence-specific DNA recognition — though a concrete molecular mechanism for how a tripeptide achieves tissue-specific gene regulation has not been established even within the Khavinson literature and has not been independently validated by Western structural biology or chromatin research. A senescent-rat tumor-modifying study (Levdik and Knyazkin, Bull Exp Biol Med 2009) reported Cardiogen modified M-1 sarcoma growth dynamics in old animals, which is presented as evidence of age-dependent activity but is hard to interpret mechanistically — the direction of tumor-modifying effects is context-sensitive and is one of the safety signals that argues for caution rather than a straightforward therapeutic claim. Human cardiomyocyte data, structural data on the proposed DNA binding, and any formal receptor or binding-partner characterization are absent.
Evidence Snapshot
Human Clinical Evidence
None. No human clinical trials of Cardiogen are indexed in PubMed for any cardiovascular, aging, or other indication. Russian-language clinical observations circulate in Khavinson-aligned publications and consumer marketing material, but none meet Western randomized-controlled-trial standards.
Animal / Preclinical
Limited. An organotypic myocardial tissue-culture study in young vs. old rats (PMID: 20210190) showed age-dependent stimulation of cell proliferation. A tumor-modifying study of Cardiogen on M-1 sarcoma in senescent rats (PMID: 20396706) described modulation of tumor growth dynamics. Cardiogen appears alongside other short peptides in the broader Khavinson tissue-specificity literature (PMID: 17152728). Beyond these, the Cardiogen-specific PubMed footprint is thin.
Mechanistic Rationale
Weak to modest. The broader Khavinson direct-DNA-interaction hypothesis has some mechanistic support for other peptides in the catalog (notably Livagen, which has clearer ex vivo chromatin-decondensation evidence in human lymphocytes), but Cardiogen-specific mechanistic data — structural characterization of claimed DNA binding, identification of regulated gene sets in cardiomyocytes, receptor or transporter identification — is essentially absent. The proposed framework is at least internally consistent with the rest of the Khavinson catalog; it is not independently validated.
Forms & Administration
Cardiogen reaches users through two primary channels: Russian-market oral capsules sold as dietary peptide complexes (Peptides.ru / Khavinson Peptides brand line), and Western research-chemical injectable lyophilized powder labeled 'not for human use.' Russian protocols describe short courses (10–30 days) of daily oral capsules repeated periodically. Research-chemical injectable protocols, where used, follow the subcutaneous convention of other Khavinson short peptides at roughly 100–200 mcg per dose, reconstituted in bacteriostatic water. No Western clinician operates a validated Cardiogen protocol. All peptides should only be used under the guidance of a qualified healthcare provider — and for any cardiovascular condition, standard cardiology care is dramatically better evidenced than Cardiogen. Never self-administer without clinician oversight.
Common Questions
Safety Profile
Common Side Effects
Cautions
- • Not FDA-approved; not recognized as a medicine by any Western regulatory authority
- • No human clinical trials — published evidence is rodent and ex vivo tissue culture only
- • Quality, purity, and even identity cannot be assumed from research-chemical supply
- • Claims around post-infarct recovery and heart failure exceed what the evidence supports
- • Should never be substituted for standard cardiology care in any cardiovascular condition
What We Don't Know
No formal human safety studies exist. No human pharmacokinetic characterization, no human dose-finding, no long-term safety data. The proposed mechanism (tissue-specific gene expression modulation in cardiomyocytes) raises theoretical concerns about unintended proliferative or arrhythmogenic effects in diseased myocardium that have not been adequately addressed even in animal models, let alone in humans with structural heart disease. Interactions with standard cardiovascular pharmacotherapy are uncharacterized.
Legal Status
United States
Not FDA-approved for any indication. Not recognized as a dietary supplement ingredient and not on the FDA's list of peptides eligible for 503A compounding. Research-chemical injectable Cardiogen is sold as 'not for human use' lyophilized powder, a channel not authorized for clinical administration. Russian-market oral capsule products are sometimes imported informally, but that is not a validated clinical pathway.
International
Sold in Russia under the Peptides.ru / Khavinson Peptides brand as an oral dietary peptide complex positioned as a functional food rather than a registered prescription medicine. Not approved as a medicine by EMA, MHRA, Health Canada, or TGA. Not established in any Western cardiology practice.
Sports & Competition
Not specifically named on the WADA Prohibited List. Injectable Cardiogen is reasonably read as falling under WADA's S0 catch-all category for substances 'not currently approved by any governmental regulatory health authority for human therapeutic use.' Athletes subject to WADA code should treat injectable Cardiogen as prohibited.
