Results from this study3

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

Studies that did not test the peptide alone3

In this study, the peptide 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 the peptide.

    Summary · context
    At the end of 2017 and 2018 two different unknown suspicious preparations were encountered and were subjected to a plethora of different analyses in order to identify, if present, any bioactive compound.

    In this study, Selank was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Selank.

    Summary
    Therefore, these findings served as an incentive to develop a novel combined liquid chromatography tandem mass spectroscopy (LC-MS/MS) methodology, applicable to both hydrophilic or more hydrophobic peptides, which was utilized to analyze a total of 10 putative cognitive enhancing polypeptides, with…
