I had the same situation too bro and I had the same feeling, I just couldnt be off!
I was on GH in my last cycle for 3 months (10 IU ed) and continued for 3 more months when I was off cycle (5 IU ed), and I have done insulin both on cycle for 5 weeks (20 IU ed) and off cycle for three weeks (10 IU ed). Note that you cant stay on insulin more than 5 weeks because there is a high risk of diabetes.
Here is my results: When I was on GH after the cycle, it kept most of my gains, kept my body fat low and helped me recover better and I was feeling great, but when I added insulin (only for the last 3 weeks when I was on gh) in there as the "bridge cycle" I didnt gain anything and was just looking watery, I believe insulin works much better in the cycle, but as far as GH, it works anytime.
This is how I took them:
On cycle: I was taking 5 IU of HGH and 10 IU of insulin in the morning, 5 IU of HGH before training, 10 IU of insulin post workout. Very good gains!
Off cycle: 5 IU of HGH and 5 IU of insulin in the morning, 5 IU of insuling post workout. Kept most of my gains but when i threw insulin in there, I was still weighing the same maybe 4-5lb more but I was just looking bloated and at the same time I didnt have the feeling when I took it on cycle. So I would recommend you to just take insulin with AAS so they would keep your body fat low and you can have the most benefit of insulin at the same time. or you can take it with high dose of HGH if you don't want to get fat and watery while taking insulin off cycle. So I would just stick with HGH and keep insulin just for the bulking cycle with AAS.
Hope that helped!
