Ipamorelin ★ Recommended

Growth Hormone

Ipamorelin is the most selective and cleanest growth hormone secretagogue peptide — it stimulates pulsatile GH release without raising cortisol, prolactin, or other unwanted hormones. Each injection produces a sharp GH pulse lasting 2–3 hours that closely mimics natural patterns. The CJC-1295 + Ipam...

  • Selective GH pulse without cortisol elevation
  • Improved body composition over time
  • Enhanced recovery and sleep quality
  • No significant side effects at normal doses

Dose: 200–300 mcg

Frequency: 2–3x daily on empty stomach

GHRP-6

Growth Hormone

GHRP-6 is one of the original synthetic GH releasing peptides, producing potent GH pulses (2–10x baseline) via ghrelin receptor activation. It also significantly increases cortisol, prolactin, and appetite. The hunger-stimulating effect through ghrelin is both a side effect and a benefit for those n...

Key Benefits

  • Very strong GH pulse (2–10x baseline)
  • Increases appetite (useful for bulking)
  • Potent anabolic effects

Which Should You Choose?

Ipamorelin is the cleaner, more selective option for long-term use — no cortisol or prolactin elevation. GHRP-6 produces a stronger GH pulse but raises cortisol and causes significant hunger.

About Ipamorelin

Ipamorelin is the most selective and cleanest growth hormone secretagogue peptide — it stimulates pulsatile GH release without raising cortisol, prolactin, or other unwanted hormones. Each injection produces a sharp GH pulse lasting 2–3 hours that closely mimics natural patterns. The CJC-1295 + Ipamorelin combination is the most popular peptide stack for anti-aging and performance. Excellent safety profile makes it ideal for long-term use.

About GHRP-6

GHRP-6 is one of the original synthetic GH releasing peptides, producing potent GH pulses (2–10x baseline) via ghrelin receptor activation. It also significantly increases cortisol, prolactin, and appetite. The hunger-stimulating effect through ghrelin is both a side effect and a benefit for those needing caloric surplus for bulking. Combined with CJC-1295, it produces synergistic GH secretion. Many practitioners prefer Ipamorelin for long-term use due to GHRP-6's cortisol elevation.

Frequently Asked Questions

Q: Is Ipamorelin or GHRP-6 better?
A: Ipamorelin is better for long-term anti-aging due to its clean hormonal profile. GHRP-6 is stronger but raises cortisol.
Q: Can Ipamorelin and GHRP-6 be stacked?
A: Yes — some protocols combine them for maximum GH pulse with selective backup, though it increases cortisol concerns.
Q: Which causes more hunger?
A: GHRP-6 causes significant hunger through ghrelin activation. Ipamorelin causes minimal to no hunger.
