    Summary
    GH peak values were higher in DM 1 patients than in control volunteers, after GHRH (52.2+/-9.8 vs. 19.3+/-6.0 microg/L; P = 0.016), GHRP-6 (66.2+/-9.6 vs. 39.9+/-6.3 microg/L; P = 0.05), and GHRH plus GHRP-6 (81.8+/-4.4 vs. 53.7+/-8.2 microg/L; P = 0.01).

    Six type 1 diabetic males and six age-, sex-, and body mass index-matched control volunteers were studied.
    Summary · context
    Each subject received GHRH (100 microg iv), GHRP-6 (90 microg iv), and GHRH plus GHRP-6 on three separate days.

Studies that did not test the peptide alone2

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.
