quick question about Viagra and L-a

Is it okay to take viagra while I’m on NOx2? Viagra says don’t take nitrates, but I don’t know what a nitrate is. Thanks.

I’m not sure, I’m on NO2X as well, and also am going to be taking V, I think it will add to the effect, but not sure. I sure I’ve read on here where guys are taking both with no problems.
