I'd keep cardio moderate and adjust it based on how well you're recovering. Too much can definitely be counterproductive, especially if you're already training hard. If you're also using Reta, I'd pay extra attention to your energy levels, hydration, and overall recovery. More cardio isn't always better.

Reta can increase your resting heart rate and causes an increased need for electrolytes and hydration. I would say hydration and cardio are more important when taking reta

Same amount, bro.

Reta doesn’t really change your cardio needs. Just do the amount your goal and recovery require.

What does Reta have to do with having a healthy cardiovascular system?

Do as much cardio as your goals require my guy
