I see a lot of guys here recommending to use mk677 for atleast 6 months. On the other hand a lot of people say mk677 will get your insulin sensitivity down a bunch when using too long >3 months.
if ran properly you won't have any of these issues, just like HGH you would have no issues either. it is those that ABUSE that get the insulin sensitivity issues.
i recommend sarms.forsale for your nutrobal and run it at the correct dose.
