Ah. Yes, it will. I expained somewhere in this forum, why and how fast. But can't say where nearly every second post is about MK-677

That's the reason why I'm using it for a short period of 50 days. But there where also studies about a longer intake. But they also showed, that the serum values decreased the longer the intake is. Therefore, if you want to have constant levels for a longer period of time (e.g. as an addition to a AAS cycle) the intake of exogenic HGH would be the better choice than the MK-677.
As said (somewhere in the AM forum

): the benefit of such a drug abuse over a short period of time (one to three monts) or a moderate period of time (three to four months) is much more higher than a intake of 12 months or more.
Of couse, the values like GH or IGF-1 were in the studies after 12 months intake more or less higher than on natural levels (depending of the age of the drug abuser). But the benefit curve is a logarithmic decrease.
And there are also financial and health aspects. Do you really want to take a experimental drug over a year? Can you afford that?
