Is this a difference in Pseudoephedrine hcl or sulfate vs. Ephedrine HCL. If so what, as far as dosing for ECA stack? I am goning to try an ECA but am looking at what I have available. I plan on using a 6x per day 10mg Ephedrine, 100mg caffeine and 150 to 180 mg aspirin. In conjuction with my CLA that I am currently taking.
