Studies that did not test the peptide alone1

In this study, Sermorelin 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 Sermorelin.

    In steers, solubility and volume limitations made delivery of hGRF(1-29)NH2 by osmotic pump problematical.

    In plain wordsIn steers, osmotic pumps were hard to use for this peptide because of solubility and volume limits.

    Summary
    Solubility and volume limitations render hGRF(1-29)NH2 delivery via osmotic pumps problematical.

    In this study, Sermorelin 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 Sermorelin.
