I have no issues with anything.
I started at 300 at night. Then went to 400 at night. Slept fine.
Then on early workout days, anytime before 5pm, i do 200 after and then 200 at night.
no hunger issues, sleep fine also.
In a recent thread i think it was made a point in a study that the use of GHRP or GH itself, i cant recall, will help induce the begining of the sleep cycle.
