How badly does tren affect cardio?

[NYC BIG MIKE]

I agree with the others.However when lifting heavy,I do get short of breath.It's takes time for me to recover from each set.I get extremely winded.And at times it's been quite alarming.

Funny thing is, my last tren cycle I was doing a 12, 10, 8, 6 sequence of reps and I found the lighter 12 and 10 rep sets a bitch and looked forward to the heavier 8 and 6 rep sets.
