GHRP-6 5mg (1 vial)
GHRP-6 is a peptide in the growth factor family. It has strong effect on the release of Growth Hormone (GH). Its main use is to promote food intake by stimulating hunger and aid in energy metabolism. It can be used in the treatment of GH deficiency as well as cachexia, eating disorders and obesity.
GHRPs are a small family of peptides acting at the pituitary and the hypothalamus to release Growth Hormone. Growth hormone releasing peptide (GHRP-6) is a synthetic hexapeptide which specifically stimulates secretion of growth hormone (GH) by pituitary somatotrophs. GH secretagogues present a tool for furthering the understanding of the control of GH secretion, as well as a unique therapeutic opportunity. These compounds activate the receptors of a putative endogenous ligand in the hypothalamus and pituitary. Acting as functional somatostatin antagonists, GH secretagogues potentiate the actions of GHRH such as C JC-1295 on GH secretion, enhancing pulsatile GH secretion.
Growth hormone (GH) has been also been known to enhance immune responses and stimulate the immune system, whether directly or through the insulin like growth factor-1 signaled secretion caused by GH.
GH responses to GHRH, physiologic hypothalamic stimulus, and GHRP-6 a synthetic hexapeptide that binds the Ghrelin receptor, were studied in rats treated with streptozotocin (STZ), an experimental model of diabetes. Sprague-Dawley male rats received a single injection either of STZ (70 mg/Kg in 0.01 M SSC, i.p.) or of the vehicle (0.01 M SSC). GH responses were challenged with two different doses of GHRH (1 and 10 microg/kg) or GHRP-6 (3 and 30 microg/kg) and with a combination of both at low (1 + 3 microg/kg) or high (10 + 30 microg/kg) doses, respectively. We observed a dose-dependent effect for GH responses to GHRH both in STZ-treated rats and in controls. However, we could not find significant differences between STZ-rats and controls. GH responses to GHRP-6o ccurred in a dose-dependent manner in STZ-rats, but not in controls. GH responses to GHRP-6 in both groups were clearly lower than those elicited by GHRH. GH responses to 30 microg/Kg of GHRP-6 were significantly greater in STZ-rats than in controls (AUC: 3549.9 +/- 1001.4 vs. 2046.4 +/- 711.7; p < 0.05).
Thusly, the combined administration of GHRH such as CJC-1295 plus GHRP-6 is the most potent stimuli for GH. The administration of doses in the lower range (1 + 3 microg/Kg, GHRH + GHRP-6 respectively) induced a great peak of GH in STZ-rats and in control rats, revealing a synergistic effect of GHRH and GHRP-6 in both groups. When the higher doses were administered (10 + 30 microg/kg), GH levels in time 5, and AUC were significantly higher in control rats. (Yolanda Diz Chaves, Carlos Spuch Calvar, Diégo Pérez Tilve, Federico Mallo Ferrer 2003) One can conclude that GHRP-6 acts at the hypothalamus to stimulate secretion of GHRH, and at somatotropes to restore and enhance the responsiveness of somatotropes to GHRH. Thusly, the combination of GHRP-6 or GHRP-2 and a GHRH analog such as CJC-1295 is the most effective synergistic combination to induce (GH) Growth Hormone response.
Description:
Growth Hormone Releasing Peptide-6 Synthetic is a single, non-glycosylated polypeptide chain containing 6 amino acids, having a molecular mass of 873 Dalton and a Molecular formula of C46H56N12O6.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility:
It is recommended to reconstitute the lyophilized GHRP-6 in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Stability:
Lyophilized Growth Hormone Releasing Peptide-6 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GHRP-6 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Purity:
Greater than 98.0%
1 vial (5mg)
