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

Studies that did not test the peptide alone5

In this study, Elamipretide (SS-31) 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 Elamipretide (SS-31).

    The SS31-rapamycin conjugate carried by red blood cell hitchhiking prolonged the half-life of SS31 by 6.9 folds.

    In plain wordsCarrying the SS31-rapamycin conjugate inside red blood cells made SS31 stay in the body 6.9 times longer.

    Summary
    The new RBC hitchhiking strategy enables the encapsulation of conjugate into RBC via a less traumatic and more natural and permissive manner, resulting in prolonging the t1/2 of SS31 by 6.9 folds.
