| Attribute | Cortagen | Cartalax |
|---|---|---|
| Category | Longevity | Recovery |
| Research Stage | Preclinical | Preclinical |
| Mechanism of Action | Cortagen is a synthetic tetrapeptide, Ala-Glu-Asp-Pro (AEDP), created by the Khavinson group through directed synthesis based on the amino-acid composition of Cortexin, a polypeptide complex extracted from the cerebral cortex [PMID:15159690]. It is a… | Mechanism of Action Cartalax's proposed mechanism is the Khavinson short-peptide framework applied to cartilage: passive membrane permeation, nuclear import, and sequence-selective chromatin modulation producing chondrocyte-favourable transcriptional shifts.… |
| Half-Life | Unknown (tetrapeptide; estimated <4 hours) | No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured. |
| Typical Dose Range | — | 20 mg oral/sublingual once daily for 10 days; 60-90 day washout |
| Dosing Frequency | once_daily | Once daily |
| Administration | Subcutaneous, Intramuscular | — |
| Side Effects | — | Side Effects and Safety Cartalax has been used in Russian clinical settings for roughly 20 years with a sparse adverse-event literature — reassuring in direction, insufficient for confident pharmacovigilance. Reported short-term adverse effects -… |

Cortagen: potential benefits
- Peripheral nerve repair - accelerated axon regeneration and faster nerve-conduction recovery after injury in rat models [PMID:11276314; PMID:12134478]
- Neuroprotection and antioxidant activity in the cerebral cortex and in chronic brain-ischemia models (preclinical) [PMID:18239817; PMID:21476278]
- CNS/cognitive support as the synthetic short-peptide analog of the cortex-derived Russian drug Cortexin
- Anti-aging chromatin remodeling - reactivation of age-silenced ribosomal genes in lymphocytes from elderly donors [PMID:15085253; PMID:37042594]
- Mild immune-signaling modulation (IL-2 expression), generally weaker than Vilon or Epithalon [PMID:12447482; PMID:16224591]
- Longevity-protocol stacking as one of the Khavinson short-peptide bioregulators (commonly paired with Epitalon or Pinealon)
Cartalax: potential benefits
- Joint and cartilage repair support
- Connective tissue maintenance
- Anti-aging effects on musculoskeletal system
- Improved joint mobility
Frequently asked
What's the difference between Cortagen and Cartalax?
Cortagen is a longevity that cortagen is a synthetic tetrapeptide, ala-glu-asp-pro (aedp), created by the khavinson group through directed synthesis based on the amino-acid composition of cortexin, a…. Cartalax is a recovery that mechanism of action cartalax's proposed mechanism is the khavinson short-peptide framework applied to cartilage: passive membrane permeation, nuclear import, and sequence-selective…. The two differ in mechanism, half-life (Unknown (tetrapeptide; estimated <4 hours) vs No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured.), and typical dose range.
Which has the longer half-life, Cortagen or Cartalax?
Cortagen has a half-life of Unknown (tetrapeptide; estimated <4 hours). Cartalax has a half-life of No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Which is cheaper, Cortagen or Cartalax?
Lowest listed price on BodyHackGuide: Cortagen from $79.00, Cartalax from $49.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers.
Can you stack Cortagen and Cartalax?
Stacking depends on mechanism overlap, safety profile, and goals. Cortagen and Cartalax should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
