How will you know? I will tell you right now if you haven't noticed anything and you have been on them since May then it is garbage. When I used Humatrope at 3-4iu per day, within 2 days there was a dramatic increase in muscle fullness, roundness, vascularity, and the pump was greatly enhanced in the gym. All pharma GH is nearly the same in terms of results, with some slight differences between brands, but in general you will get close to the same results. I honestly wouldn't trust anything coming from Turkey, or anywhere overseas, especially when it comes to GH. I'm sure there might be some legit stuff amongst all the junk, but why take the chance, when you will always be wondering in the back of your mind if the GH is real or not? Using GH should be an enjoyable experience, not always wondering if your GH is legit.
