DLXphil,
I hear what you are saying, or the part that i can relate to and that's do the research.
in that regard, i did what i felt was due diligence prior to taking the tren, i read info at one of the ph message boards and also read all the info at american cellular labs website and never came across any info informing me not to take an NO at the same time.
this is the world of the multi-billion dollar supplement bidness, contra-indications might be hard to come by at one time or another.
