Description
GHRP-6 is a hexapeptide designed to stimulate growth hormone production. Researchers have found that it achieves this by inhibiting somatostatin, the hormone responsible for regulating growth hormone release. By blocking somatostatin, the hormone that inhibits GH secretion. Sarmsamerica offers GHRP-6 in a 5 mg vial, presented as a white powder.

GH-releasing Peptides (GHRPs) are synthetic Peptides that stimulate pituitary somatotrophs, much like GHRH, to promote growth hormone (GH) release. Among these, GHRP-6 has been extensively studied and is believed to act at both pituitary and hypothalamic sites. Known as Growth Hormone Releasing Hexapeptide, GHRP-6 was developed to enhance the body’s natural GH production.
GHRP-6 functions as an agonist of the growth hormone secretagogue receptor, stimulating the pituitary gland to release growth hormone into the bloodstream. Uniquely, GHRP-6 does not disrupt the body’s natural hormonal balance; it simply enhances the system’s natural production in larger quantities.
Molecular Mechanisms of GHRP-6 at the Ghrelin Receptor
The synthetic Peptide GHRP-6 can stimulate growth hormone release similarly to the endogenous hormone ghrelin, though their structural differences suggest different mechanisms of action. Recent structural analyses of the ghrelin receptor (GHSR1a) reveal how GHRP-6 activates this receptor to promote hormone secretion.
Unlike ghrelin, GHRP-6 lacks the acyl modification essential for ghrelin binding to GHSR1a, instead binding to an alternate site on the receptor. This induces a distinct conformational change compared to ghrelin but still activates the same downstream signaling cascades. Thus, while their binding interactions differ, GHRP-6 mimics the functional effects of ghrelin, stimulating appetite and growth hormone release.
Structural characterization of GHRP-6 binding to GHSR1a shows that synthetic growth hormone secretagogues can modulate this receptor through unique mechanisms. Identifying an alternative binding pocket and activation mode paves the way for designing improved GHRP analogs.
Comparison of the Effects of Ghrelin, GHRP-6, and Motilin in Rat Model
The study compared the gastroprokinetic effects of ghrelin, growth hormone-releasing Peptide 6 (GHRP-6), and motilin in rats both in vivo and in vitro. Ghrelin and GHRP-6, but not motilin, accelerated gastric emptying and transit in rats, with ghrelin showing greater potency than GHRP-6. Notably, ghrelin’s dose-response relationship was bell-shaped, unlike that of GHRP-6.
In antral and fundic strips, neural responses to electrical field stimulation (EFS) featured an on-relaxation that was reversed into a cholinergically mediated contraction with the addition of NG-nitro-L-arginine methyl ester hydrochloride (L-NAME). Ghrelin agonists reduced on-relaxations in fundic strips and increased cholinergic off-contractions in both antral and fundic strips. The concentration-response curves for muscle strips of the fundus were bell-shaped, showing maximal effects for ghrelin and GHRP-6. [4]
No effects were observed with motilin across the various experimental conditions. The presence of growth hormone secretagogue receptor 1a (GHSR1a) transcripts in the strip preparations was confirmed by reverse transcriptase polymerase chain reaction (RT-PCR). [4]
In conclusion, ghrelin and GHRP-6 accelerate gastric emptying and transit by activating cholinergic excitatory pathways in the enteric nervous system, in addition to the known vagal pathways. Motilin, however, did not exhibit similar effects under the studied conditions.
Effects of GHRP-6 on Septic Ileus in Mice
The study investigated the effects of ghrelin and growth hormone-releasing Peptide 6 (GHRP-6) on gastric emptying and transit in both control and septic mice. Mice were administered lipopolysaccharides (LPS) to induce sepsis or saline as a control. Following a 16-17 hour period, mice received pretreatments of saline, ghrelin, or GHRP-6 before intragastric administration of Evans blue dye. Gastric emptying, transit, rectal temperature, and behavioral scale were assessed.
In control mice, both ghrelin and GHRP-6 accelerated gastric emptying, while transit remained unaffected. Septic mice displayed delayed gastric emptying and transit, hypothermia, and worsened behavioral scale scores. [5]
In septic mice, ghrelin accelerated gastric emptying without affecting transit, while GHRP-6 significantly accelerated gastric emptying in a dose-dependent manner without significantly impacting transit. Neither ghrelin nor GHRP-6 affected endotoxin-induced hypothermia or behavioral scale deterioration. [5]
The study suggests that the prokinetic effects of ghrelin and, particularly, GHRP-6 could offer therapeutic potential in treating septic gastric ileus.
Blocking Ghrelin Signaling Promotes Fatty Acid Metabolism
The hormone ghrelin plays a critical role in appetite regulation, and growth hormone secretion, and impacts glucose and lipid metabolism. Recent research explored inhibiting its actions in a porcine model using a receptor antagonist.
Pigs treated with the ghrelin blocker showed heightened hepatic fatty acid oxidation and gluconeogenesis. The antagonist promoted the expression of genes involved in liver fat metabolism and glucose production. Elevated serum growth hormone levels were observed, likely attributed to blocking ghrelin’s negative feedback on its release.
Reversing Anabolic Steroid-Induced Hormone Suppression with GHRP-6 and Clomiphene
Researchers investigated a therapeutic approach to counteract hypogonadism and testicular dysfunction induced by anabolic steroid abuse in male rabbits. They administered the anabolic agent oxymetholone to deliberately induce hypogonadism, resulting in shrunken testes, reduced testosterone levels, and impaired sperm counts and motility after one month.
To address this iatrogenic hormonal imbalance, the rabbits were treated with a combination of GHRP-6 and clomiphene citrate. GHRP-6 stimulates natural growth hormone production, which in turn enhances testosterone synthesis. Clomiphene citrate acts by directly stimulating gonadotropin secretion in the brain and testes to further boost testosterone production. This dual treatment strategy successfully restored testicular size and function, normalized testosterone levels, and improved fertility parameters.

GHRP-6 FAQs
What Is GHRP-6 Peptide Used For?
GHRP-6, also known as growth hormone-releasing Peptide 6, is a Peptide that mimics the action of Ghrelin to stimulate appetite and elevate plasma levels of growth hormone.
Is GHRP-6 Better Than HGH?
The pulsatile release of natural growth hormone (GH) induced by GHRP-6 is generally more compatible with mammalian physiology compared to the continuous administration of exogenous growth hormone-releasing hormone (GHRH). Peptide secretagogues like GHRP-6 or Ipamorelin may also help prevent the suppression of natural pituitary GH release that often occurs with exogenous GH administration.
What Does GHRP-6 Do to You?
Growth hormone-releasing Peptide (GHRP-6) is a synthetic hexapeptide designed to stimulate the secretion of growth hormone (GH) by pituitary somatotrophs.
What Are the Disadvantages of GHRP-6?
A substantial increase in appetite and fluid retention has been observed in test subjects administered GHRP-6 and this may increase cortisol or induce connective tissue discomfort.
