The MK-677 hasn’t made me lethargic so far this go around which would be the first time that’s ever happened, the hunger after one hour of ingestion is there but not as strong as usual and I contribute that to the Rad-140 possibly hurting my appetite (most orals do to me). I’ll be able to give a better over all review of the MK-677 once I finish up all the Rad-140 which will be in about 6wks. Now I will say the Rad-140 (Iv never taken before so I can’t compare brands) has added strength and some clean size to me and it hasn’t made me feel like crap which s23 and 4033 both made me feel bad so I’m definitely a fan of Rad/140 and seems to be the only oral I can handle these days, I’m just glad I found one I can deal with. It’s slightly curbed my appetite I think but nothing to bad like most other orals do. So far I’m on week 3 I think and I’m pleased. I’ll post again at the end of next wk.
