I've seen these non label ones before from China. The ones I had were pretty decent and did the job. One word of advice take your dose and if you don't feel anything in a few days up your dose (not by to much) I say by 1 iu. If you have had growth before you would know if its real or fake. If they are bluetop without any label on them don't be alarmed most generics growth from China comes like that.
