Human pharmacokinetics of exogenous LL-37 are not well characterized. 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, LL-37 or Cartalax? LL-37 has a half-life of ~30 minutes (free peptide; rapidly cleared by proteolysis). Human pharmacokinetics of exogenous LL-37 are not well characterized.. 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, LL-37 or Cartalax? Lowest listed price on BodyHackGuide: LL-37 from $45.00, Cartalax from $49.99. Prices are pulled from the vendor listings tracked on BHG and change frequently.
