| Attribute | Thymalin | Cartalax |
|---|---|---|
| Category | Peptides | Recovery |
| Research Stage | Clinical (Russia-registered; not FDA-approved) | Preclinical |
| Mechanism of Action | Thymalin's mechanism of action is less precisely defined than that of single-molecule peptides, because the active principle is a mixture of peptides acting through multiple parallel pathways rather than a single well-characterized molecular interaction. The… | 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 | Short for the individual peptides in the mixture (on the order of minutes to a few hours). Biological effects persist for weeks to months after a 10-day course, which is why Thymalin is given in discrete courses rather than continuously. | 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 | 5-15 mg | 20 mg oral/sublingual once daily for 10 days; 60-90 day washout |
| Dosing Frequency | Once daily during a 10-day course; courses repeated 1-4 times per year (commonly biannually). | Once daily |
| Administration | — | — |
| Side Effects | Thymalin has a substantial safety record spanning four decades of Russian clinical use across hundreds of thousands of patients, with a relatively clean side-effect profile compared to many immunomodulatory agents. Common side effects (1-10% incidence in… | 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 -… |
| Molecular Weight | Not a single value - Thymalin is a thymic polypeptide EXTRACT (a mixture), not one defined molecule; its components are low-molecular-weight peptides, generally under ~10 kDa. Characterized active dipeptides: KE (Lys-Glu, ~275 Da) and EW (Glu-Trp, ~333 Da). | 333.29 g/mol |

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 (Short for the individual peptides in the mixture (on the order of minutes to a few hours). Biological effects persist for weeks to months after a 10-day course, which is why Thymalin is given in discrete courses rather than continuously. 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, Thymalin or Cartalax?
Thymalin has a half-life of Short for the individual peptides in the mixture (on the order of minutes to a few hours). Biological effects persist for weeks to months after a 10-day course, which is why Thymalin is given in discrete courses rather than continuously.. 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, Thymalin or Cartalax?
Lowest listed price on BodyHackGuide: Thymalin from $44.99, Cartalax from $58.85. 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 Thymalin and Cartalax?
Stacking depends on mechanism overlap, safety profile, and goals. Thymalin 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.
