GHRP-6 5mg
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide known for its strong ability to stimulate natural growth hormone (GH) secretion and significantly increase appetite. As a member of the growth hormone secretagogue (GHS) family, GHRP-6 is of interest in research involving muscle growth, fat metabolism, tissue repair, and recovery. Its action on the ghrelin receptor makes it a powerful tool for studying anabolic and metabolic processes.

Its action on the ghrelin receptor makes it a powerful tool for studying anabolic and metabolic processes.
GHRP-6 functions as a growth hormone secretagogue, acting directly on the ghrelin receptor (GHS-R1a) to promote pulsatile GH release from the anterior pituitary. In contrast to GHRH analogues, GHRP-6 bypasses traditional hormone regulation pathways, making it particularly useful in combination studies. It has been studied for its impact on body composition, inflammation, appetite signaling, and recovery from catabolic conditions.

What is GHRP-6?
GHRP-6 is a six-amino acid peptide that mimics the action of ghrelin, the “hunger hormone.” It stimulates growth hormone release, enhances appetite, and may support fat metabolism and muscle preservation. Its dual action on GH secretion and feeding behavior makes it a valuable peptide for exploring anabolic and metabolic pathways in both normal and GH-deficient models.
Key Functions and Benefits
Growth Hormone Release: Strongly stimulates natural GH secretion.
Appetite Enhancement: Notably increases hunger and food intake via ghrelin receptor activation.
Muscle Growth and Recovery: Supports protein synthesis, muscle repair, and recovery.
Fat Metabolism: Promotes lipolysis and may contribute to fat loss or body composition changes.
Anti-Inflammatory Properties: Research suggests it may reduce inflammation markers and aid in tissue healing.
Mechanisms of Action
GHRP-6 activates the growth hormone secretagogue receptor (GHS-R1a), leading to a rapid, pulsatile release of GH from the anterior pituitary. This effect is independent of the GHRH pathway, allowing for synergistic effects when combined with GHRH analogues like CJC-1295 or Sermorelin. It also stimulates appetite by mimicking ghrelin, making it uniquely effective in research involving undernourished or cachexic models.
Unique Characteristics
Compared to other GHRPs, GHRP-6 is particularly known for its strong appetite-stimulating effect—more pronounced than GHRP-2 or Ipamorelin. While this can be beneficial in certain research applications, it may also influence study outcomes where controlled caloric intake is desired. GHRP-6 is often selected when the goal is to stimulate both GH release and food consumption.
