Been working out for 10 years now, and have always rotated the ECA stack in my diet.

I know it was taken off the market, And I have been adjusting with Vasopro (ephedrine) 25mg, Aspririn, and 200mg of caffeine. Most bodybuilders are familiar with this, and my question is...how detrimetal is this in the long run?

How safe is it to run this dose all year long? or is it absolutetly nesscesary to cycle it on and off. I usually only take it to go the gym, I do not exceed 100mg of epehdrine/day.
