I was afraid this would happen when I heard what source you were using for MK-677. We've stated many many times that MK-677 is the most faked sarm of all because of the price of it and it's raws. Many times its replaced and cut with other things including prohormones. It sounds like you are experiencing shutdown, which a true GH secretogue would never ever do, since it has no effect on the HTPA whatsoever.
