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, GHRP-6 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 GHRP-6.

    In healthy adults, physical activity, lunch and the time between tests did not significantly change the GH peak of the GHRH plus GHRP‑6 test.

    In plain wordsIn healthy adults, activity, lunch and time between tests did not change the growth hormone peak in the combined GHRH and GHRP‑6 test.

    Summary
    When analysed individually, physical activity, lunch or time elapsed between the two tests did not significantly change the GH peak in the subjects tested.

    Summary · context
    Seventeen healthy volunteers of both sexes were tested twice on separate occasions with the sequential administration of GHRH (90 microg i.v.) plus GHRP-6 (90 microg i.v.) as bolus.

    In healthy adults, the GHRH plus GHRP‑6 test gave a similar GH peak in the morning and after lunch on the same day.

    Summary
    The reproducibility of the GHRH + GHRP-6 test performed on the same day was high, with the mean GH peak being 65.4 +/- 8.0 microg/l in the basal state and 51.2 +/- 9.6 microg/l after lunch, while the area under the curve (AUC) was 2287 +/- 288 microg/l per 45 minutes in the morning and 1759 +/- 350 after lunch.

    Summary
    When a period of 6 months had elapsed between the first and the second test, the reproducibility was well maintained with a mean GH peak of 42.7 +/- 6.2 microg/l in the basal state and 34.3 +/- 3.6 microg/l in the after lunch test, with the AUC 1463 +/- 209 and 1164 +/- 106 microg/l per 45 minutes i…
