What got worse for some people
In their own words
“Have you tried ECA stacks for energy? If you're like me, they will barely work, if at all”
“I used to take 24mg of ephedrine and 200mg of caffeine three times a day (look up ECA stack)... Probably terrible for you, but handy in a pinch.”
“I've always been a fan of thermogenic compounds ,such as Clenbuterol and other ECA stacks, but they were way to stimulating where's C3G/BG are a very clean mood enhancement.”
“My hands are blue...(lack of oxygen transport)...the supplement cannot compete with the pathway Ephedrine uses to constrict blood vessels”
“For both colds and flu I love the ECA stack. I usually do 200mg caffeine, 25 mg ephedrine (Primatene,) and a 325 mg aspirin.”
