GROWTH-HORMONE PATHWAY COMPARISON

Three Pathways. One Goal.

Ipamorelin/CJC-1295, Tesamorelin, and Sermorelin all work through the growth-hormone axis—but each is studied for a different research focus. Compare them side by side, then explore the one that fits your goal.

The three pathways in detail

Growth & Recovery

Ipamorelin/CJC-1295

Established

A 1:1 blend delivering the strongest, most sustained GH release of the three. Studied for building lean mass, accelerating recovery, and enhancing performance.

  • Lifters and athletes seeking muscle growth and strength
  • Those wanting the strongest GH pulse and recovery benefit
  • Improving body composition with a performance focus
  • Support for deeper sleep and training adaptation

Metabolic & Visceral Fat

Tesamorelin

Established

Specifically studied for deep abdominal (visceral) fat reduction. Targets harmful VAT while preserving lean muscle and supporting metabolic health.

  • Those focused on visceral fat loss
  • Waist circumference and metabolic-health goals
  • Preserving lean mass while reducing fat
  • HIV-lipodystrophy or abdominal-obesity research

Gentle & Balanced

Sermorelin

Established

The original GHRH peptide—mimics natural GH release in a gentle, physiological way. Studied for overall wellness, vitality, and long-term hormonal support.

  • Overall wellness and anti-aging
  • Gentle GH support without extremes
  • Better sleep, energy, and daily vitality
  • Long-term protocols with excellent tolerability

WHY RESEARCHERS COMPARE THEM

One axis, three strategies

Targeted Outcomes

Each peptide has distinct strengths—muscle, visceral fat, or gentle wellness—for a specific research goal.

Complementary Roles

Because they emphasize different outcomes, researchers study how they map to different objectives rather than as interchangeable options.

Well-Characterized

All three act on the well-understood growth-hormone axis and each carries an Established research-maturity rating.

How to read this comparison

Ratings reflect each compound's studied research emphasis relative to the other two—not absolute effect sizes or a promise of results. All three are offered strictly for laboratory and research use. See each compound page for its full Evidence Snapshot and research findings.
