sermorelin is a secretagogue, or a hormone that induces another hormone. in this case, sermorelin is used to induce growth hormone. supposedly, it is alot safer, and definitely alot cheaper than hgh. also, sermorelin can be taken continously, unlike hgh, which should only be taken for about 6 months, due to negative feedback loop issues. i've been on sermorelin for about a month and a half now, and to be honest, i havent noticed much of a difference. im gonna give it another month or two, and if i dont notice anything spectacular, i will discontinue use. costs me $185 per month. suppossed benefits supposed to include better sleep, more energy,etc etc etc. supposedly, if you mix ghrp-2 or ghrp-6 with the sermorelin, you will see dramatic results, unfortunately however, my pharmacy only carries straight sermorelin without the peptides
