The… | | Half-Life | 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. | 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. | | Typical Dose Range | 20 mg oral/sublingual once daily for 10 days; 60-90 day washout | 5-15 mg | | Dosing Frequency | Once daily | Once daily during a 10-day course; courses repeated 1-4 times per year (commonly biannually). | | Administration | — | — | | 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 -… | 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… | | Molecular Weight | 446.5 Da (C18H30N4O9) | 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). | | Common Vial Sizes | — | — | ## Price History 3 data points - Ion Peptide - Disguised Alpha - LB ## Price History 2 data points - Ion Peptide - Disguised Alpha ### Cartalax: potential benefits - Joint and cartilage repair support - Connective tissue maintenance - Anti-aging effects on musculoskeletal system - Improved joint mobility ### Thymalin: potential benefits - No structured benefit list published. ## Frequently asked ### What's the difference between Cartalax and Thymalin?

The two differ in mechanism, half-life (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. vs 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.), and typical dose range. ### Which has the longer half-life, Cartalax or Thymalin? 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.. 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.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, Cartalax or Thymalin? Lowest listed price on BodyHackGuide: Cartalax from $49.99, Thymalin from $44.99. 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 Cartalax and Thymalin? Stacking depends on mechanism overlap, safety profile, and goals. Cartalax and Thymalin 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. ## See current vendor prices Listings from the vendors we track.
