GHRP-6 VS GHRP-2 REVIEW | GHRP FOR SALE
Please Read our Disclaimer
In this article, we will be comparing GHRP-6 and GHRP-2 to help you make an informed decision on why you should choose to buy either hexapeptide despite their many similarities. These two growth hormone-releasing peptides have been discussed in the blogs GHRP-6 and GHRP-2.
A BRIEF INTRODUCTION OF GHRPs
Growth hormone-releasing peptides GHRPs are synthetic, non-natural peptides equipped with potent stimulatory effects on Growth hormone secretion in animal test subjects. They have no structural resemblance with Growth Hormone-Releasing Hormone and act through specific receptors present either at the pituitary or hypothalamic level in animals. The GH-releasing activity of GHRPs is noticeable and dose-related after intravenous subcutaneous intranasal and oral administration.
Though the way GHRPs work is still a blur, available data postulates that they could act by counteracting somatostatinergic activity both at the pituitary and hypothalamic level and partially through a GHRH-mediated mechanism.
GHRP-6 is the first hexapeptide to be extensively studied in mammals. Recently, GHRP-2 was synthesized and also available for animal studies.
The activity of Growth Hormone Releasing Peptides is lower than Growth Hormone Releasing Hormone. It is affected by glucose, free fatty acids, glucocorticoids, and exogenous somatostatin, which suppresses the effect of GHRH.
STRUCTURAL DIFFERENCES BETWEEN GHRP6 AND GHRP2
|AMINO ACID SEQUENCE
MECHANISM OF ACTION
The mechanism of action of GHRP-6 and GHRP-2 on GH release was investigated on experimental animals. Both peptides are associated with the classic effects of growth hormone receptor secretagogue receptor activation significantly increasing growth hormone and insulin-like growth factor 1 in experimental animals. GHRP-2 was found to stimulate GH release from rat pituitary cells via the same receptor, with a slight variation when compared to GHRP-6. GHRP-2 increases intracellular adenosine 3,5-monophosphate cAMP concentration like that of Growth Releasing Factor (GRF) while GHRP-6 causes a decrease in cAMP levels.
COMPARING AND CONTRASTING THE EFFECTS OF GHRP-6 AND GHRP-2
GHRP-6 and GHRP-2 have similar effects on animal test subjects but differ structurally. They both act on the pituitary gland to release growth hormone. The main difference is the amount of growth hormone released by both hexapeptides. The other differences are listed in the table below.
