i dose the same as jipped does and i can only tolerate it for about 3-4 weeks before the lethargy gets to be to much for me. i also didnt get any of the apppetite issues that some do with it. def get a bit of cts and water retention in the begining but damn if the lethargy isnt the worse for me. i tried to use it in the am and same thing about 3 wks in and bam fall asleep anytime i stop moving. so i do not suggest am dosing with this stuff. something pretty cool with mk that i found out just at random is that it doesnt surpress your t3/t4 pathways like gh use does even after 6 weeks on. i wasnt actually checking that theory out but had labs at almost the 6 week mark and mine stayed in the normal range. around the 6 week mark on gh at 3iu a day and both are crushed in myself. well not rock bottom but low and def not optimum. so it works much differently than gh. i like to stack it up with gh and ipam
