It pairs BPC-157's angiogenic, pro-healing activity - driven largely through VEGFR2 and nitric-oxide (Akt-eNOS) signaling (PMID: 40789979) - with TB-500's actin… | 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 | BPC-157: short - under ~30 min in animal PK studies (rats/dogs); no human PK data. TB-500 (thymosin beta-4): active fragment ~30 min, though tissue effects are prolonged. | 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 | Dosed per component (a fixed daily blend over-doses TB-500 - see notes). BPC-157: 250-500 mcg once daily SUBQ. TB-500 (thymosin beta-4): 2-2.5 mg twice weekly during a 4-6 week loading phase, then 2-2.5 mg once weekly for maintenance (~5 mg/week during loading). If a pre-blended fixed-ratio daily vial is used, its TB-500 fraction should be ~250-350 mcg per injection so the weekly TB-500 total stays near ~5 mg. | 20 mg oral/sublingual once daily for 10 days; 60-90 day washout | | Dosing Frequency | BPC-157: once daily SUBQ. TB-500: twice weekly during the loading phase, then maintenance ~2-3x/week or once weekly for TB-500 as needed. | Once daily | | Administration | Subcutaneous, Intramuscular | — | | Side Effects | See individual compounds. Generally well-tolerated. Injection site reactions, mild nausea, headache. Rare: temporary fatigue. | 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 | BPC-157: ~1419.5 g/mol (average; molecular formula C62H98N16O22). TB-500 (thymosin beta-4): ~4963 Da (full 43-residue peptide). | 446.5 Da (C18H30N4O9) | | Common Vial Sizes | 5mg, 10mg | — | ## Price History 4 data points - OF - BM - Half Nattys - BHG Labs - RC ## Price History 3 data points - Ion Peptide - Disguised Alpha - LB ### BPC-157/TB-500 Blend: potential benefits - Accelerated tissue healing (preclinical/anecdotal) - Reduced recovery time - Anti-inflammatory support - Complementary repair mechanisms: angiogenesis (BPC-157) plus actin-regulated cell migration (TB-500) ### 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 BPC-157/TB-500 Blend and Cartalax? BPC-157/TB-500 Blend is a recovery that a combination of bpc-157 and tb-500 (thymosin beta-4) in a single formulation. it pairs bpc-157's angiogenic, pro-healing activity - driven largely through vegfr2 and nitric-oxide…. 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 (BPC-157: short - under ~30 min in animal PK studies (rats/dogs); no human PK data. TB-500 (thymosin beta-4): active fragment ~30 min, though tissue effects are prolonged. 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, BPC-157/TB-500 Blend or Cartalax? BPC-157/TB-500 Blend has a half-life of BPC-157: short - under ~30 min in animal PK studies (rats/dogs); no human PK data. TB-500 (thymosin beta-4): active fragment ~30 min, though tissue effects are prolonged.. 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..
