My doc always tests for IGF to see how GH is doing. My lab range on the report showed as 67 - 215. My test came back as 68 so I was put on a script for 0.2mg - 0.4mg of Omnitrope which works out to be 0.5iu - 1iu. After doing 0.2mg 5 days on 2 off for a month, my level came up to about 120. Doc wants me over 200 so I'm now doing 0.4mg 5 days on 2 off.
