I got a script for it a while back from a "nice" doc. It is pharmaceutical bro. You cant get any cleaner and more accuratley dosed. I have used it 3 times and know a ton of people that have also used it. I love it. Used at 400 mg per week and 600 mg per week. both with great results. I had the 200 mg p/ml version. They also make a 100mg p/ml. I have seen a few fakes out there so make sure u trust your source.
