| Attribute | BPC-157/TB-500 Blend | Cartalax |
|---|---|---|
| Category | Recovery | Recovery |
| Research Stage | Preclinical | Preclinical |
| Mechanism of Action | 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 (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) |

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.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
