im new to using hgh and have started taking some of the generic blue top stuff from china and was wanting to put my mind at ease by taking an igf-1 blood test to see if the stuff is legit. first question! is this the correct test to be taking to determine what im wanting to know or is there a better way? 2! is there a specific time i should take the test as in time of day or time after an injection. 3) how long do you think i should actually be taking the gh before i take the igf-1 test or does it matter? thanks for any info.
