Bolasterone (myagen)
This was originally a popular oral steroid being used in Europe. It had functions similar to dianabol, but it has long since been discontinued. Several years ago bolasterone became the first big name counterfeit steroid to be internationally marked.
Belonging to a group of steroids titled the DDR compounds, inferring they came from East Germany, this steroid was billed as the best drug ever made. It became very popular partially because several respected steroid experts were in on the production of it, and gave it rave reviews in their publications. Thousands of 30 cc vials of this injectable steroid were sold at a price of over 200 dollars a piece.
It was said to contain ten miligram of the drug per cc, but it actually contained a low dosage of several domestic steroids mixed together. In the spring of 1986 the makers of this drug were busted. There are still at least three other counterfeiters using the bolasterone name: UCLA bolasterone, available in a 10 cc vail; new bolasterone, available in a 10 cc vial, and bolasterone depot available in a 50 cc vial. All of these items are the worst kind of counterfeit steroids made. They are worthless and dangerous. Many athletes are still taking these drugs. It is obvious that any item carrying a bolasterone or GDR label should be avoided.
