Is hexarelin the same as GHRP-6?
No. They are different six-amino-acid peptides in the same ghrelin receptor family. Hexarelin's profile lists a molecular weight of 887.0 daltons and three studies in people. One found that in 12 volunteers, a dose into a vein released about twice as much growth hormone as GHRH. Another followed 12 healthy older people for 16 weeks as the response faded. GHRP-6's profile lists a molecular weight of 873.0 daltons and no studies in people on this site. It is the older one in the family that makes people hungrier. Sharing a receptor family does not make them the same molecule or give them the same evidence. This site does not rank them. Full records at /compounds/hexarelin and /compounds/ghrp-6.
