Sorry for the late review, ordered Mk-677 a few weeks ago and it's working well. I'm on test/dbol currently so I can't say much for any strength gains I've noticed specifically, but I can say the hunger is crazy. The hunger was actually the effect I was looking for so it's perfect, also very cool to be buying MK in pill form for the first time, can just down it with water and not worry about that terrible taste.
Overall exactly what you'd expect from MK, my friend just started his MK and that's all he's taking so will give an update on his progress later on if I can. In terms of customer service it was fine by me, quick reply and shipping info was also sent fast, emails were all very to the point. Will definitely order MK from here again.
