Im have been researching this lately as i got some humatrope 15 iu and not too sure if its real or fake. Where i live ,it would be tough to get tested . Im no stranger to gh but just sometimes you can tell if the gh works especially when you are younger but as u get older in the 50`s ,gear and gh dont work as well as they use to. Especially if there is alot of gh that is fake. I could say for sure genetropins that i had from unclez back years ago ,i could really notice some great gains. I also was taking my gh blast with genetropins after the workout ...things were great . Now at 57 , when your body function is starting to slow down , good quality gh should be more noticeable than ever. Also as u get older, u want to make sure that your choices of buying gh is more researched than ever. Its the age thing. I say a video if u didnt have access to a blood igf test,you can test your blood sugar and if the gh was real your blood sugar should go up somewhat after the injection. Can anyone comment on that? Also i saw this video and website from a trainer talking about genotropins, humatrope and omintrope and how to spot fake ones? Here is the link.Anyone have some experience with spotting these fake ones? https://fakehgh.com/
