I 100% understand you about the MK-677. But the tiredness does significantly improve over time. I also recommend dosing in the morning/afternoon compared to pre bed. The hunger hits me in the night after work and I can devour insane amounts of carbs... notice I put carbs and not food! I must have had about 800g carbs the other night over 2 hours. I am ok now with some will power and I plan to get an appetite suppressant. Huperzine A gives you a good mental boost when using the MK-677 (and of course will increase GH output). Good luck with your SARM cycle
