.8 cc of water or 80 units on a slin pin will = 8iu.....I recommend taking HGH either in the morning on a empty stomach and wait at least 30 minutes before eating any carbs or choice 2 I recommend is taking 2hrs before your workout that way when you get a hr into workout your gh levels are hitting peak. I would stay start out with 2-3 iu really depends on what you are trying to achieve. 5 IU is all I take and I only do on workout days. that way do not start to become insulin resistant. Cinnamon and Chromium capsules will help regulate blood sugar.
