So since my last post I have tried MK677 again followed up with CJC W/DAC after a couple weeks off. Hands down CJC W/DAC. I can't take MK677 more that 2 days a week and at only 10mg on those days. I get terrible carpal tunnel symptoms in my shoulders and elbows if I take more then that. I also get bloated and watery. I don't think I will take it ever again. CJC w/DAC on the other hand is great. Take EGCg and Huperzine A morning and night to prolong the effects.
