GHRP-6 vs Hexarelin
Research Verdict
Neither compound has a universal evidence advantage. Both peptides serve distinct research goals with comparable evidence; choose by target mechanism.
Quick Answers
Which is better, GHRP-6 or Hexarelin?
Neither compound has a universal evidence advantage. Both peptides serve distinct research goals with comparable evidence; choose by target mechanism.
What is the key difference between GHRP-6 and Hexarelin?
GHRP-6 produces significant appetite stimulation (useful in cachexia research); hexarelin has minimal appetite effect but binds cardiac CD36 receptors - the cardiovascular vs. orexigenic side effect profile differentiates them.
Evidence Comparison
GHRP-6: extensive ghrelin receptor pharmacology data, well-characterized appetite stimulation. Hexarelin: similar GH potency plus cardiovascular CD36 receptor research (Bodart 2002, Bhatt 2006). Neither approved. Comparable GH evidence quality; hexarelin has the unique cardiovascular dimension.
Evidence Context Favoring GHRP-6
Research where appetite stimulation is a desired or studied effect, or ghrelin receptor pharmacology is the focus.
Evidence Context Favoring Hexarelin
Cardiovascular research exploring CD36-mediated cardiac effects of GH secretagogues.
