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.
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.
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.
| Protocol | Compound 1 | Compound 2 | Timing | Duration |
|---|---|---|---|---|
| Anti-Aging | HGH 1-2 IU/day AM | Ipa 200mcg PM | AM HGH, PM Ipa | 16-24 weeks |
| Body Comp | HGH 2-3 IU/day AM | Ipa 200mcg 2x/day | AM HGH+Ipa, PM Ipa | 12-16 weeks |
| Performance | HGH 3-4 IU/day split | Ipa 300mcg 2x/day | AM/PM both | 12 weeks |
| Panel | Markers | Timing |
|---|---|---|
| GH/IGF-1 | IGF-1, GH (fasted) | Baseline, Week 6, Week 12, Week 24 |
| Metabolic | Fasting glucose, insulin, HbA1c | Baseline, Week 8, Week 16 |
| Thyroid | TSH, free T3, free T4 | Baseline, Week 12 |
| Basic | CBC, CMP | Baseline, Week 8 |
IGF-1 monitoring is paramount. HGH can suppress thyroid function - check TSH and free T3/T4. Glucose important as GH is diabetogenic at high doses.
Yes, at moderate HGH doses (1-3 IU), the pituitary is not fully suppressed and ipamorelin can still trigger additional GH pulses. At very high doses (5+ IU), endogenous production may be suppressed.
Anti-aging: 1-2 IU daily plus evening ipamorelin. Body composition: 2-3 IU with twice-daily ipamorelin. The ipamorelin allows 30-50% less HGH while achieving comparable IGF-1 levels.
Ipamorelin preserves natural pituitary pulsatility, allowing 30-50% lower HGH doses with comparable IGF-1 levels. The evening ipamorelin augments the natural nocturnal GH surge, while lower HGH doses mean fewer side effects.
