I tried Cardarine approx 4 months ago. Within 3 days I felt very lethargic all the time, tried to stick it out, but just couldn't. After 2 weeks of use, I stopped and within 48 hours felt back to normal. Last week, I thought I would give it another go, sadly by day 2 the same effect happened. I almost feel like what I have is not Cardarine (O.L. UK brand). Any thoughts?
Side note, both times I have been taking ECA although that should not make a difference ?
