    Summary
    Thymosin beta 11 appears to replace the more prevalent thymosin beta 4 in at least two species of bony fish, and represents the sixth structurally characterized member of this widely distributed family of peptides.

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

Studies that did not test the peptide alone1

In this study, Thymosin beta-4 (human) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin beta-4 (human).
