What are black beauties?

15 years ago i took them and they were speed. I dont know the actual clinical name.

Black beauties are

Biphetamine (Amphetamine/Dexamphetamine combo) which came in a black capsule containing 20 mg.

Black Beauties (Biphetamine) simply aren't marketed any longer. The government put pressure on the last company to hold the patent on them many years ago and they, along with most diet pills, were withdrawn forever.

Shame too because they filled a niche. Millions of people took them with no addiction nor problems. But a few thousand people overtook them, ignoring the manufacturer's recommendations, and became addicted. Plus they were being sold enmasse on the street to drug users that liked them.

But we live in a country where it's ok to dump fluoride in the water but stevia in processed foods is against the law. You figure it out. I cannot.
