Biphetamine - Was manufactured right here in Rochester, NY (circa 1968-1973). It was frankly, hard to believe that this drug was actually legal! I knew a UPS driver that used to service the Pennwalt plant. He would sell us sealed bottles of 400 20mg capsules (BB) for $150.00. This was without a doubt the best speed EVER available, bar none - legal or illegal. 18hrs of tooth gritting, high energy, nothing-can-stop-me-now, balls to the wall, can you handle it speed - AWESOME! Oh lord, please let someone manufacture these again (and let the DEA approve). Oh how much more I could do with my life if Black Beauties were plentiful again.
