I feel like I’m still feeling some effects of the 6-APB, even though it feels the effects are finished. How come?

After using 6-APB or Benzofury, it takes about an hour before you start to feel the effects. The peak then lasts for about four to six hours, after which the effects diminish somewhat but are still present. Therefore, be careful with redosing if you feel a little less effect. The (after) effects can even last up to 12 hours. Many people have difficulty sleeping after using 6-APB. Therefore, rest well before and after use, so that your body gets the chance to recover.
