I would use about 3iu every day.To start, you need to get some bacteriostatic water. Thats all over the next. Comes in 30 ml vials I believe. If you add 1cc water a vial, each .10 will be 1iu gh. I like Hyge GH a lot. The big name pharm gh is quite expensive but if you can afford it, you will get 100% quality for sure. I would start with either generics or Hyge. You‘ll also want insulin syringes. The big 3cc barrels are too big to measure that small amount of liquid
