Results from this study4

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

Natural levels measured4

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.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Other

    In bucks, immunofluorescence detected Humanin in elongated spermatids of the caput epididymis and in the interstitial space of the testes.

    Summary
    Immunofluorescence examination of the male reproductive tract revealed the presence of green fluorescence, indicating humanin, in the elongated spermatids of the caput epididymis and the interstitial space of the testicles.

    Summary · context
    A total of 12 bucks were selected, and an indirect immunofluorescence test was conducted to detect humanin using a commercially available anti-humanin antibody.
