I have been thinking about peptides - particularly GHRP/GHRH - the ones that signal the pituitary gland to release growth hormone and as it's simply a natural pulse, would younger guys benefit more from this peptide combo, because their natural production is still very high therefore allowing to get more out of the pituitary?
I think the elders wouldn't benefit as much as young guys because their natural GH production is next to zero.
But the HGH would be more suitable for elders because young guys produce a lot of GH naturally and they would need a very high dose to get any benefits. While old people GH production is next to zero and they would benefit from even the slightest dose of GH.
