Are we talking about ephedrine, caffeine, and aspirin (ECA)?
If so it was banned in the U.S. for a while now I'm seeing water downed versions being sold on the internet...
25 mg of ephedrine, 200 mg of caffeine and 325 mg of Aspirin is the most effective per serving...you can build up a tolerance for this stuff so a week or 2 layoff (cycling is usually effective) Best used when exercising for maximum fat loss..
Raises blood pressure so monitor accordingly, dont take 4 hours before bedtime, drink plenty of water, watch for anxiety, nervousness, cut back.....see and talk to your Doctor regularly.....
Home made ECA stack = Primatene + cup of coffee and aspirin
