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.

    Summary
    Thymalin accumulates only in young cells of the skin ectodermal epithelium and mucosa of the anterior portions of the digestive and respiratory systems.

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

    Summary
    After appearance of keratin the cells no longer accumulate thymalin.

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

    In human ectodermal epithelium, natural thymalin content showed age-associated involution, as in the thymus.

    In plain wordsIn lab tests, natural thymalin content in human epithelial tissues declined with age, as in the thymus.

    Summary
    Similarly as in the thymus, thymalin content in the ectodermal epithelium of the organs is subjected to age-associated involution.

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