GH secretagogue / appetite effects
GHRP-2 vs GHRP-6
Both are ghrelin-receptor agonist secretagogues; human literature is primarily physiology/endocrine research, not body-composition efficacy.
At a glance
GHRP-2
GHRP-6
Human evidence
Small human physiology studies show GH release, increased food intake and activation of ACTH/prolactin pathways.
Small human studies characterize exposure and show route-dependent GH, ACTH/cortisol and sleep effects.
