Is there a drug named prelude bi62?

There was a drug called Bi-62 or better known as preludes. It was prescribed up until the late 80's for weight loss in the extremely obese . Addicts loved it because of the euphoric effects it had especially when injected. It was a pink pill with the letters BI62 written on one side. These pills were timed released and prescribed one per day usually in the morning. The abuse factor with these pills was so high, the FDA did take them off of the market(1989). Addicts were loosing control and robbing pharmacies specifically for this drug. Some addicts just liked to take these by mouth, but the majority of the users of this drug injected. It was quite an art form to master the cooking process of the Prelude in preparation for injecting it, but it was also like riding a bike, you never forget. I injected preludes on 5 different occasion's, have never felt anything like it before. Instant orgasm.
