yes, ECA stack - ephedra, caffiene, aspirin.
Typically the ECA stack is consumed two or three times per day in a 1:10:10 or 1:10:15 ratio of ephedrine: caffeine: Aspirin.
Usually, no more than 25 mg of ephedrine, 200 mg of caffeine and 325 mg of Aspirin is consumed in a single dose.
It is not recommended that the stack be taken past mid evening as this may contribute to insomnia.
This should also be cycled; as 3 weeks on, 2 weeks off, etc…
you can find the ephedra through a Asthmatic Bronchial Dilator called Bronkaid (there is another form, but at the moment i forget the name)...
caffiene through caffiene supps (pills) or Red Bulls, Monsters (sugar free).
i usually forgoe the aspirin as i am concerned with stomach ulcers and bleeding of the intestins (horror stories from EMT friends i guess)...
i have found this stack to be one of the best supps at cutting; it worked wonders for me when i was competitvely boxing and needed to cut weight in a short period of time.
hope this helps
i often interlace the terms Ephedra/Ephedrine as the same, even though they are infact different compounds...
