What do you guys recommend as far as ECA stacks? Is there a certain company that puts out a good product, or would I need to look for the components seperately? My wife and I are both doing Atkins, but she gets really fatigued now doing any excersize. We have been doing Atkins since New Years, I have bounced back to my regular amount of training, but the wife is still not back to normal. Any suggestions would be appreciated.
