Results from this study3

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

Natural levels measured3

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 adult female rats, the body's own thymosin alpha‑1 increased with GnRH agonist treatment, while thymosin beta-4 did not.

    In plain wordsIn rats given GnRH agonists, the body's own thymosin alpha‑1 rose.

    Summary · context
    We studied the effects of two GnRH agonists on the adult female rat thymus in 4 experiments.

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

    In adult female rats, thymic weight correlated positively with the body's own thymosin alpha‑1.

    In plain wordsIn rats, thymus weight went up together with the body's own thymosin alpha‑1.
