Short answer
Sermorelin is a GHRH-fragment analogue that acts upstream at the pituitary GHRH receptor. Ipamorelin is a ghrelin-mimetic GHRP that triggers GH release through a different receptor pathway. They are not interchangeable molecules. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
