Growth hormone problem:


Human growth hormone (hGH) is a hormone that interact with most tissues in human body, a shortage in hGH in early stages may cause decreased muscle mass, increased fat mass and undesirable of alteration in blood lipid concentration [1]. The injection of hGH has serious side effects such as carpal tunnel syndrome, so that secretagogues was suggested [4]. The treatment for this problem is to use hGH itself (a peptide with 191 amino acids) by controlling the hGH secretion. The growth hormone releasing hormone (GHRH) and somatostatin (SRIF) are two hormones that are known to control the release of hGH [2]. In 1984, Momany and others introduced a small peptides called GHSs that has a distinct mechanism other than GHRH and SRIF [3].



Ibutamoren (MK-677):


MK-677 is known as L-163,191 in different scientific articles [4] [5]. In 1995, A group of research at Merck discovered a receptor to which MK-677 binds. Ibutamoren MK 677 is a derivatized dipeptide which is used in clinical trial as oral active GHS. The reason that GHS is consider the best oral active drug among others: GHRH, SRIF, and hHG is its low molecular weight [4].



The scientific benefits of MK-677:


The results show that MK-0751 increases the secretion of GH in young male volunteers [5]. The results show that MK-677 increases the level of GH in dogs after oral doses as low as o.125 mg/kg. The Figure below shows that when a dosage of MK-677 (L-163, 191) increases from 0.01 mg/kg to 0.1 mg/kg the associated mean serum GH from 5 to 35 ng/ml during the peak value [4]. In addition, Ibutamoren MK 677 does not cause any water retentions. 


Figure 1. the effect of MK-677 on growth hormone releasing [4]. 


Side effects of MK-677:



The results showed that the release of GH using MK-677 does not significantly affect the plasma level of aldosterone, prolactin, luteinizing hormone, and thyroxine after oral administration of 1mg/kg [4]. The results showed an increase in cortisol. Thus, the MK-677 was selected for clinical studies. However, it is not approved by the FDA for human consumption.
