I have used GH 3 times. Each time using 1 kit over 12 weeks. I take 2ius 5 days on 2 off. I usually stack it with test and insulin.
Your trainer doesnt know what he is talking about.
Mix the sterile water with the powder. Using an insulin needle, every 5.5ius = 1iu of GH. I took 1iu twice a day( mid-morning and late afternoon)
I would usually lose about 2 inches off my waist and 3-5% BF. I love the stuff. I'm 245lbs and 2ius ED works awsome for me.
