No validated human dose for any physique or anti-aging use exists. In clinical research GHRP-6 has been given as a single ~1 mcg/kg dose for provocative GH/HPA-axis testing, and at 100-400 mcg/kg in single-dose pharmacokinetic work. Anecdotal grey-market 'GH-boosting' protocols circulate online but have no clinical basis, no efficacy validation, and should not be read as a recommendation.
