I am about to start HGH and I want to see if it is working so would I be correct if I got blood work now and checked my IGF levels now then in a coulpe of weeks after I started using HGH would I see a difference? I know IGF doesnt hang around long but if I have the blood work done... say hour after HGH injections I should see a change in my IGF levels. right?? considering its real and working.
