Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Other

    In male rats, castrated animals had higher serum levels of thymosins (thymosin alpha1 and thymosin beta4 were measured) than intact animals.

    In plain wordsIn rats, castration raised the body's own thymosin levels in blood compared with intact rats.

    Summary
    In addition, immunoassays were used to measure thymosin alpha1 and thymosin beta4 levels in sera from intact and castrate rats. Castrate animals displayed greater sera levels of thymosins compared to sera from intact animals.

    This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.
