Growth Hormone / Body Composition StackEvidence Grade: A (HGH) / B (Ipamorelin)
HGH + Ipamorelin Stack Protocol Guide
The HGH + Ipamorelin stack combines exogenous recombinant human growth hormone with a selective GH secretagogue. Exogenous HGH provides reliable, dose-dependent GH supply bypassing pituitary limitations, while ipamorelin triggers additional natural GH pulses through ghrelin receptor activation without suppressing endogenous production at moderate doses. This allows lower HGH doses (reducing cost and side effects) while achieving superior outcomes through maintained pulsatile release.

12-24 weeks
Synergy & Mechanism
HGH Mechanism
Exogenous HGH provides a reliable, dose-dependent supply of growth hormone that directly activates GH receptors throughout the body. It stimulates IGF-1 production in the liver, promotes lipolysis, supports protein synthesis, and provides the foundation for anti-aging and body composition effects. The limitation is that it can suppress natural pituitary GH production over time.
Ipamorelin Synergy
Adding ipamorelin allows lower HGH doses while maintaining optimal GH levels. Ipamorelin preserves natural pituitary pulsatility at moderate HGH doses, meaning the evening dose triggers natural GH pulses that augment the morning HGH injection. This results in 30-50% lower HGH requirements with comparable IGF-1 levels, reducing side effects and cost.
