Results from this study1

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

Natural levels measured1

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.

    In chicken embryos after early partial decapitation, preliminary radioimmunoassays showed a sharp increase in circulating thymic hormones, mainly the body's own thymosin beta‑4, at 17 days of incubation.

    In plain wordsIn chicken embryos with the front of the brain removed, the body's own thymosin beta‑4 in the blood rose sharply at 17 days.

    Summary · context
    The elimination of the prosencephalon in chickens at 33-38 hr of incubation induced profound structural, histochemical, and morphometric changes in the embryonic development of the thymus gland.

    This result measures the body's own Thymosin beta-4 (human). Nobody was given the peptide. It is not evidence about taking it.
