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

Studies that did not test the peptide alone3

In this study, Thymosin alpha-1 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 alpha-1.

  1. 01AnimalNot a test of Thymosin alpha-1 aloneAnimal study (in vivo)Efficacy outcome

    In male CBA mice, administration of thymopthin (a drug with 1% thymosin alpha‑1) changed the circadian rhythm of plasma corticosterone.

    In plain wordsIn mice, a drug containing a little thymosin alpha‑1 changed the daily rhythm of a stress hormone.
