What supplements are illegal to take?
It would be easier to name what ingredients to avoid. Avoid anything with Andro or the Andro family. DHEA seems to be falling by the wayside, but it will also cause a positive. Any of the fatburner type supplements that contain Ma Haung/Guarana or Ephedrine will cause a positive due to it beign a super strong stimulant. A little known fact here is that over the counter cold medicine will also cause a positive, due to the psuedo-ephedrine stimulants in it . Refrain from using the OTC cold medication 3-4 days before the meet. Buyer beware when using supplements that are cheaper and that could be spiked without your knowledge or being on the label.
