Mod-grf (CJC NO dac) and a ghrp is what you want. I dont much believe the old jargon of a saturation point, should be mostly a dose dependent mechanism.
IPA was generally used at 100mcg but it has always been considered weaker than GHRP 2/6 so now a lot use it at 200 or 300mcg. I don’t notice any effects in the gym so I wouldn’t worry about it.
