I read several articles recently, one being by the great Dat BE Tru...showing how prolonged use of MK-677 can cause PTSD symptoms and damage. However, some of the other articles sited the cause of this as prolonged release of extra cortisol. From what i have seen on several sites, is cortisol is only increased the first 2 weeks or so of use, then tapers off. I have been on MK for a while, and recently got diagnosed with severe ptsd,depression, and anxiety. However, this was due to decades of job related trauma. I just want to make sure I am not exacerbating my symptoms. Any new science out there anyone has seen to either debunk or prove any of this?
