All I know is that when I’m really working physically hard,in the gym or around the farm, I’m off-gasing serious ammonia. I can really smell it when I get in the shower.
Yes, I definitely have noticed this to (on me, not you) but for me this is more pronounced if I am out of shape and then have a strenuous workout. I workout regularly and this is not an issue. However, I will say that I can certainly tell when a non-regular comes in for a hard workout. If they are next to me on the machine I know I’m in for an unpleasant stay.
