I picked up a couple bottles of this to see how it works. Pros , Unbelievable muscle fullness and pumps , Good sleep and vivid dreams. I don't get the hunger so thats good to me. Cons , Sleepy ,Sweat more in the gym. Stomach distension to the point of pain and intestinal cramps. This kills me. I can't do a full 25 mg dosage but at around 1/4 dosage i get the good effects without the bad. I've tried ramping it up slowly but 2 days after hitting 1/2 dosage the stomach issues kick in. I really like MK677 but can only tolerate 1/4 dosage . I'm 62 so any increase in natural GH production is a plus. I'm guessing my age has a lot to do with my GH sensitivity
