Ipamorelin vs. GHRP-6

AttributeIpamorelinGHRP-6
SelectivityHigh - GH only, no cortisol/prolactinLow - GH + cortisol + prolactin + ghrelin
Appetite EffectMinimal stimulationStrong appetite stimulation
GH OutputModerate, clean, dose-dependentStrong, non-selective pulse
Best ForAnti-aging, long-term clean protocolMuscle building, caloric surplus phase
Side EffectsMinimal (transient water retention)More (hunger, cortisol elevation)

Verdict: Ipamorelin is cleaner and better tolerated for long-term use. GHRP-6 is better for appetite-driven muscle-building phases where hunger stimulation is a feature, not a bug.
