Ephedrine 25mg+ Caffeine 200mg + T3 ??

Anyone try this combination? Im on day 3 of my first week feeling kinda weird. I don't know if i want to continue. Taking 1 pill an hour before workouts. Im a bit sick with a cold but i have never felt so like tired when im doing cardio, i get loss of breath. I don't go above 160 on the heart rate monitor. Could it be the cold causing me a shortness of breath which might be the culprit or is it the pills? Feeling kinda weird i tell ya..
