Well Jimmy a serum test is from a test performed on "your own blood" not test that you read on a piece of paper sent to you by a rip off Chinese manufacture saying it is good. Didn't your mom ever say " now jimmy don't believe everything you read , do your own test to varify?". Proverb 666: Dont trust the paper it's written on.
I've done 1 serum test on my First Order of HGH.. and itwas very good.. So..... on the next order I will re-make the serum test..
But yes I was saying that you have to do a serum test from you own blood..
