What is Sermorelin & GHRP-6 Blend?

Tap any underlined term for an instant definition.

Sermorelin & GHRP-6 Blend pairs the analogue sermorelin with GHRP-6, a ghrelin-mimetic GHS with pronounced appetite-stimulating effects via motilin receptor binding in addition to GHS-R1a. This combination is particularly studied in contexts where appetite stimulation alongside GH elevation is a desired research endpoint.

What It Is

  • Sermorelin ( 1-29): on pituitary somatotrophs
  • GHRP-6: GHS-R1a agonist + motilin receptor partial agonist (producing appetite stimulation)
  • GHRP-6 is historically the first developed; strong GH-releasing activity with motilin-mediated appetite effects
  • Blend combines synergistic GH pathway stimulation

How It Works

  • Same dual-receptor mechanism as sermorelin + GHRP-2
  • GHRP-6 additionally binds motilin receptors in the GI tract, stimulating gastric motility and appetite
  • GH pulse amplification: 3-4x either peptide alone
  • The appetite effect of GHRP-6 can enhance caloric intake in research subjects, making this combination relevant for studying GH + nutrition interactions

Key Research Findings

  • GH response: Similar amplitude to sermorelin + GHRP-2 in matched dose comparisons
  • Appetite stimulation: Subjects reliably report increased hunger within 30-60 minutes of GHRP-6 injection
  • Lean mass: Studies show comparable lean mass outcomes to sermorelin + ipamorelin when diet is controlled

Dosing From the Literature

  • Sermorelin 200-300 mcg + GHRP-6 100-200 mcg per injection
  • Once or twice daily
  • Administer before expected meal if appetite stimulation is desired endpoint

Storage and Handling

  • Lyophilised: 2-8 degrees C; 24 months
  • : 2-8 degrees C; use within 30 days
