Hi,
alot of people on here ask what the effects are with tren and asthma. I have mild asthma and the tren pretty much locked down my cardio in a couple of weeks. Running on the treadmill was torture cv wise. I had to take my inhalor only a couple of times but training was very hard. The strength and mass gains were good but if you have moderate to severe asthma then I would tread carefully, very carefully.
