Results from this study4

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

Studies that did not test the peptide alone4

In this study, Thymulin (serum thymic factor) 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 Thymulin (serum thymic factor).

    Summary
    The first group, which had received zinc and thymulin, had the earliest and highest humoral immune response to SE (p<0.05). This was observed at 2 and 4 weeks after the first vaccination.
