In today’s lesson, I break down how different peptides stimulate growth hormone and why they aren’t all the same.
You’ll learn:
- The two different receptors on the pituitary that control GH release GHRH receptor (Sermorelin, Tesamorelin) GHRP / Ghrelin receptor (GHS-R1a) (Ipamorelin, Hexarelin)
- Why GHRH peptides are like the offensive coordinator (calling the play)
- Why GHRP peptides are like the quarterback taking a direct snap (fast GH dump)
- How Hexarelin is different: it has human data showing improved cardiac function (↑ ejection fraction) through ghrelin receptors on heart muscle
- Why business, not science, kept some of these from becoming approved therapies
My goal with this lesson:
▶ Help you understand where each peptide works in the pathway
▶ Help you make logical decisions about GH/IGF optimization
▶ Eliminate the confusion and bro-science around peptides
If you understand this pathway, you’ll never be sold “random peptide stacks” again: you’ll know exactly what lever you’re pulling and why.
