Well if you are still trying to drop 20kgs, there is a great chance that your diet, cardio and training isnt 100% on point, and probably have some blood sugar issues so adding in mk677 aint going to help, also the water retention that comes from mk677 will mask your "weight loss".
You need to give more details into your stats and the above mentioned things.
You probably need to be coached more so than just advised on a course of gear, as gear doesnt directly cause fatloss, yes anavar has been shown in a 12 week study to make people loose about 2-3kgs of fat, and gain 3-4kgs of muscle at 20mg dosing, but you probably need more direction than just that.
You can gain a little muscle loosing fat at the same time in your quest to drop 20kgs, but your goal should be muscle growth, and fat loss as a result of the muscle and strength gains.
