I never took var before but I had some liquid var sitting in my drawer I was skeptical of taking bc I got it over 4 months late from a vendor that was removed from SF.. but that's another story.. I been taking tren a at 525/week and my cardio was shit just like it always is when I exceed 350mg. I started taking the var 1.5weeks ago at 50mg a day and I noticed the last few workouts I had a lot more wind than normal. Does the var help combat shitty cardio sides? I planned on running it 4 weeks and come off everything except 200 test.
