use mod grf 3x/day (upon waking, post work out, before bed) with ghrp 2 100mcg each. personally i dont like the cjc w/dac - i d rather have a gh pulse than a bleed.
4iu of humulin - r wont do shit. also 8iu of humulin - r wont do shit. i would work up to 30 iu per day split between 2 shots at a minimum (20 until yo uget a bit of experience with it, if you dont have it already my pardons if you do) but caution is always advised when using slin. until you gain experience with it maybe its not a bad idea to keep the dosages low.
personally i would do one mod grf/ghrp 2 shot in the morning, wait 20 minutes then shoot your humulin - r. the insulin spike will decrease the gh pulse so the idea is to wait for most of it to finish. same thing for post work out.
