Ok ive been seeing the chart below a lot lately and its nice we have this science but for me personally it just doesnt add up. To show that ghrp/ghrh causes a max spike of 100ng/dl for 0-3hrs v.s. 7.5iu's GH with a max spike of 50 and elevation over 11 hours. So basically the ghrh/ghrp has double the spike but is shorter acting. ive used both ghrp/ghrh at 100/100 3x per day v.s. 6iu's GH per day and the ghrp/ghrh didnt come close. Far more muscle growth and fatloss from the GH at 6iu's per day. This was done using top of the line peptides and real hygetropin GH so its not an issue of the product. So what im getting at, is for overall growth/fatloss maybe it not just all about the spike or length of time the product is in your system. Maybe GH has other properties that cause better gains than ghrp/ghrh's. Dont get me wrong, ghrp/ghrh combo works great and has similar effects to GH but imo you cant compare xx dose of peptides to equal an xx dose of GH. It seems to me as if GH just does something else.
