Cardio on cycle, anbody else struggle?

I use the treadmill for my cardio, pre cycle my cardio fitness was increasing well.

The last few weeks it's felt like my fitness levels have dropped and I cannot get the same times/distance I was before.

Could this be due to the added weight I'm lugging around, or maybe the longer lifting sessions before hand?

Anyone else experience this?

It depends on what you using, I've experienced the same like you, got winded very quickly when I was using tren.

Nothing like tren, just 500mg test c p.w.

Could be the extra water weight, zaps your energy.

Increased since on cycle? A lot! Currently at about 4000.

Haven't checked bp recently, when I did it was fine but will check on Monday again. Water intake is between 5 and 6 liters a day.
