I am on 2 months of Mk677 already - Glucose levels will fluctuate - first they were higher - 10-20 days in the cycle I had it at 100+ after that it went lower to 60-70 and now for more than a month on a daily basis take it's 85-90 always. And my Mk677 is legit and I am also taking CJC 1295 DAC - bloodworks confirms IGF 1 and GH raised in level quite nice - also had some other sides - some numbness in fingers , hands but it's allright... Diet is very important too - I used to have a sweet tooth and I stoped . And it's all good now
