TweetHow much were you taking? ECA stacks are supposed to work in a similar fashion to clenbuterol. Burning fat while maintaining muscle.
Unfortunately, fat loss is one of the things that bring out the "more is better syndrome". ( If two tabs twice a day work then four tabs will work twice as fast). This is the cause of problems and even deaths with ECA stacks.
I weigh 230 and I NEVER exceed 2 doses per day and quite often take 1 half of a dose per day. It takes a little longer, but I lose weight WITHOUT doing any cardio and maintain muscle mass.
