Ultra Cordygen or cordceps in general no good for someone with EIA?

[RealBigga]

I used the original Cordygen and the Ultra one and all they did was give me brain fogginess and harder time to catch a breath. I was wondering if it had to do something with my exercise induced asthma? Is cordceps not recommended for people with asthma? Was it my mind playing tricks on me?

What are good supplements for Asthma or exercise-indused asthma? Thanks
