Sermorelin Sarcopenia Research Mechanism: Trial Comparison

JCEM 2023 (n=142, ages 65–78) 500mcg nightly 24 weeks +2.8kg (DEXA) +68% from baseline 8% mild injection site reaction Largest sarcopenia-specific trial; statistically significant lean mass gain with minimal AE profile UT Medical Branch 2022 (n=48, ages 68–75)

This comparison does not assign a generated winner or score.

  • JCEM 2023 (n=142, ages 65–78)
  • 500mcg nightly
  • 24 weeks
  • +2.8kg (DEXA)
  • +68% from baseline
  • 8% mild injection site reaction
  • Largest sarcopenia-specific trial; statistically significant lean mass gain with minimal AE profile
  • UT Medical Branch 2022 (n=48, ages 68–75)
  • 400mcg nightly
  • 16 weeks
  • +1.9kg (MRI)
  • +54% from baseline
  • 5% transient glucose elevation
  • Demonstrated mTOR reactivation via muscle biopsy; FSR increased 63%
  • Stanford Endocrinology 2021 (n=76, ages 62–72)
  • 300mcg nightly
  • 12 weeks
  • +1.2kg (DEXA)
  • +42% from baseline
  • 3% mild peripheral edema
  • Shortest intervention duration; dose may be suboptimal for maximum anabolic response
  • Comparative GH Trial 2021 (n=94, ages 65–74)
  • 500mcg sermorelin vs 0.3mg GH daily
  • Sermorelin +2.6kg; GH +2.9kg
  • Sermorelin +61%; GH +88%
  • Sermorelin 6% AE; GH 19% AE (insulin resistance, edema)
  • Equivalent lean mass outcomes; sermorelin safer metabolic profile
