This is the new version of the old Schering primobolan from Turkey. Now taken over by Bayer, but the dosage is the same. 100mgs of primobolan/ml, 1 amp = 1ml.
I've tried the Bayer primo a few times, a real pain in the butt to inject (pun intended). Really painful when you have to inject 4-6mls per week because of the low does. Quality is good though.
A friend of mine has started using recently the Primo by Berd Pharmaceuticals. He claims that it is the best Primo product he has ever tried, and he is a true fan of this steroid, so I would readily believe him.
