- For researchers studying the growth hormone axis, a fundamental question is whether to use recombinant human growth hormone (rhGH) directly or to stimulate endogenous GH release using a GH secretagogue such as sermorelin. The distinction matters enormously for study design — each approach produces a different GH profile, different downstream IGF-1 dynamics, different feedback loop engagement, and different safety profiles. This guide compares sermorelin and recombinant HGH as research tools for understanding the GH axis.
