ECA Alternatives?

ECA stacks have been around for some time essentially utilizing the same base ingredients for the 3 parts, and this formula seems to have been met with trouble when people had serious reactions to the Ephedra. I am by no means a scientist or a Dr, but read in T-mag print version a while ago that Ephedra targets beta-1 and beta-2 receptors equally whereas albuterol targets beta-2 receptors 3x as much as it does beta-1. Wouldn’t albuterol be a better alternative to Ephedra for those who have easy access to it? It so, what would be the ideal dosing regimen? Also, what about making your own ECA stack by using Ephedrine HCL? Pros and Cons? Thanks.
