Yes, i am. 
Chemicalneed Ghrp-6, i take 200mcg before bed and i don't get any hunger pains,but i hit a deep sleep for 4 hours!  But when i wake up i end up only sleeping for an hour at a time.   So i am gonna start taking another 200 mcg when i wake up the first time and see how that works. 
As for the gtg mk and s4 i am finally seeing the proverbeal yellowish tint.   However, i believe it is more of a color shift to the red end of the spectrum as reds and yellows are more saturated and much brighter.
