Too true.
testing serum levels is he only way to tell if a product is effective.

Although a review on a product by way of use is also provides feedback that others can read and make up their own minds. After my use of generic I am leaning more towards pharma grade use then generic. That is not to say I would not use generic again I may but it isn't all bad as I was happy with the product.

do a serum and igf test and then come back. I have given 4 guys 8 free kits in total to test the jintropin we've got here to prove the quality. It measured the same serum and IGF levels of other FDA approved hgh... but you always get someone saying that genotropin is better blah blah... but the tests show a lot more than just what someone thinks the effectiveness is just by feeling.
