These substitutions extend the molecule's circulating half-life from approximately 7 minutes (native GHRH) to approximately 30 minutes, a window that preserves pulsatile signalling while enabling practical research dosing protocols
So let's start there
Table 7 also lists the extra loss of essential minerals, in terms of the fraction of the Recommended Daily Allowance (RDA) lost each day, based on two reasonable assumptions: 1) averaging the loss between the 1 st and 9 th dose, and 2) assuming a daily urinary excretion of 500 mcg of creatinine, which is typical of a 60-pound child
guide is a useful read
This can lead to decreased food intake and result in favorable changes in body weight and composition, including reductions in body fat mass and improvements in insulin sensitivity [13, 14]
Considerable overlap was, however, observed between VNUT and GLP-1 in primary mouse (mean SEM: 40 6% of VNUT + ve staining positive for GLP-1, n = 19 cells) and human (54 7% of VNUT + ve staining positive for GLP-1, n = 17 cells) L-cells and this was even more pronounced when co-staining for PYY was analysed (91 3% ( n = 19) and 91 4% ( n = 18) of VNUT + ve staining cells also stained positive for PYY in mouse and human, respectively)
