The ECA stack I take promised mind-blowing pumps and steroid-like gains
The ECA stack is very interesting - metabolically! It was proven in a number of peer reviewed research studies to accelerate fat loss. But now that the evil empire (government) has stopped most ephedrine distribution it's no longer used.
Way back there were a few ephedrine products readily available- Ultimate Orange and another product called Up Your Gas
A friend of mine and I were doing a 200 mile bicycle "tour" in Canada, and on the second day I told him I felt pretty crappy and he should ride ahead of me. He refused and said "try this Up Your Gas" herbal pill. I figured what the heck since I had to ride over 100 miles just to get back to our car.
That shit was unreal. As it turned out, I rode the first 30+ miles of the ride at the fastest pace I've ever done. We completed the 100 miles in 4 hrs 20 min, which is fast given the terrain. The bad side effect was my heart rate was off the charts for a few hours afterwards haha. I never did it again.
