These were a yellow/green colorish capsule. Whatever mg that was. This was back when it had only been out for a short while (couple of years I think), and was supposed to be more competitive with Focalin (sp?) as opposed to competing with Adderall. They had a 10 trial pack at the time. He game me this because he said it was better than the others because you don't lose your appetite or sex drive. (not sure if that is true) I never finished it. I am very sensitive to stims. Right now I buy 4 Bangs for $6 (or Rockstar whichever is on sale at the moment) and drink 1/3 in the morning with breakfast. That is all I need.
Amphetamine is a crazy libido booster IME. It's not uncommon for speed freaks to jack off or fuck for like 6 hours straight until you have sores on your dick. Heard this "sores on your dick" story many times.
Vyvance is actually an approved nedication for binge eating disorder so it does reduce appetite in many. First time I tried it it was even hard to drink water.q
