Currently running 600mg of Deca and 500mg of Testc a week. Having excellent gains, but has killed my cardio. When doing cardio I get a massive pump in my calfs with in a few minutes of starting, it hurts so bad I have to stop. I would like to be able to run since it is something I enjoy. Can somone suggest a good stack to help with weight loss while maintaining strength but not kill my cardio?
