    Ephedrine is one of the four active components of the herb Ephedra. It is able to induce fat loss via increasing the amount of fat available for fuel as well as by increasing heat expenditure. It has been implicated in increasing the metabolic rate by up to 5% in humans. It has also been noted to cause serious side-effects in some instances, and its legal status varies by region.

    Overview

    Dosage information

    All Doses Standardized to Ephedrine HCl

    In an ECA stack, ephedrine is dosed at 20-24mg for three doses taken throughout the day.

    Human studies have found success with ephedrine in isolation on fat metabolism with doses of 20-50mg thrice a day. The higher range (150mg) may be too stimulatory for some, and can induce headaches or light hand tremors.

    Ephedrine tends to be consumed with xanthine compounds like caffeine and sometimes with Aspirin. The combination of Ephedrine and caffeine is shown repeatedly to be highly synergistic.
