I just switched my protocol to 300mcg sermorelin/300mcg ipamorelin/300mcg ghrp-2 at bedtime and i'm using a pen to inject. The products arrived today and are loaded in the pen but i'm not sure how many 'clicks' to inject. 1 cartridge is a 30 day supply and i only inject 1/day at bedtime. the cartridges are 3ml each. the pen is an Autopen Classic insulin pen. thanks.
