Oh. You're a teenager. I would talk to your parents or guardians than. They might know more of what will work or not work on you. Herbs/medicine of any kind can be toxic if mixed. So check and see if you dont have any allergies, or health issues, or on any medications. In other words...talk to your parents about it.
Have you tried the natural approach at LDing without the suppliments? You're still young so this is a good time to get into the art of LDing from a natural means. When ya get older you'll feel good knowing you can LD at times natural and don't have to fall back on herbs/legal drugs.
