Beware of fake Norditropin 40iu kits. All original box, security code, inserted documents, labels and vial. How they did it was to remove the original GH from the vial by removing the flip top lids and replace with fake powder and recap the flip top lids with another Red flip top cap. How I figured it out was to test the reconstituted mix by doing a protein boil test in hot water. Mix did not turn milky white so I knew it was not a protein. Next I injected 10ius and did my BW. Labs came back zero GH on my Serum and IGF-1 number was very low. Also I didn't get my usual edema in my ankles and leg like I normally get with other brands.
