Hello all. I am 39 years old. 6 foot 2.5" and 217 pounds...about 15 percent body fat...i have been on humalog for 7 weeks...injecting 12 i.u.'s 4 times a week after workout. Also, have stacked it with injectable ghrp-6 (10 i.u.X 3 a day) and dac ( the dac once a week). As for testosterone inducing stuff, i have been taking 200 mg of dhea every morning and some tribulous after the 4 workouts a week i manage. My gains were significant. Little fat gained. I have read i should cycle humalog once a month...then off a month...also have read contrary info...How long can i safely stay on Humalog before I have to go off?
