Don't use the ephedrine.
It is a component of many diet pills and energy drinks and things of that nature. It is very similar to caffeine, Ma-huang. It causes release of NE (norepinephrine) out of storage vessicles withing your neurons (similiar to amphetamine, but not as potent) and it then diffuses out of the neurong where it can activate other SYMPATHETIC neursons. This gives the "rush" feeling (increased heart rate, increased energy, increased blood pressure, etc) It is a very unselective drug (like epinephrine) and I don't suggest using it for anything. The effects on the hear alone should make you not want to use it. It has no benefits in muscle growth, and slight benefits on breakdown. But overall, this is not worth using. The sides outweigh the benefits
