Is supplement safe when depressed?

I recently bought PlasmaJet Liquid Nitric Oxide Maximizer (Myotrophic Hyperexpension) at my local gym and have read some warning and said do not take it if you are taking any medication for any psychiatric or mental disorder. I am curious since I am taking Lexapro for depression at the moment and work out at the gym. I really want to gain muscle and wants to take it but just want to ask would this medication drive me crazy or it is safe? I stay away for Alcohol as much as possible since it effect the liver and also put me in a depress mode again but does this supplement have the same side effect or it is safe to take it while working out?
