If those brands are not counterfeits they are very, very good. That country they come from has (mental count) about 10 'export only' companies that have complete lines. I've never tried them but I always stay in the know by email and they send you pics, price lists, and have every generic med that is made at their disposal. Well, except GH for under $5/iu. It's real though. On that note I do not trust most of the GH pens as another big nation vendor told me they counterfeit the pens. They use real GH but I'm a bit jaded about that. It's just so damn shady. And me saying 'shady' it's shady. I at least have had vendors that would tell me If I find the pics maybe I'll post them.
