My advice playing with insulin is be very cautious! I would only use levmir at 20-40iu in the morning one hour after I wake up and take 2iu of hgh then after the insulin wait 15 mins and start eating! Eat clean and a lot during a bulk with bcaa during the workout with a little Gatorade and use on lagging body parts I use during back and leg day primarily and at most 3 or 4 x per week maybe on chest day too! Works very well stay big and full with 2-4 iu of hgh…just my advice works good for me like that
