I've been into sport for 25+ years- I have always been fit, boxed, ran a marathon, played footy etc

I've also enjoyed substances on and off, some nights smoking cigs/vape etc.

Believe me, Zyn had the most noticeable effect on my cardio. Even after just a few days of use.

When boxing, there would be a limit on how much my lungs could take in- not like after a night of cigs when the lungs & airways are closed.

So, for anyone wondering if Zyn bad for your athletic performance, in my experience, yes!

All the best.
