Can you suffer psychological side-affects from peptide abuse?

[Monotone Zygoma]

I'm using combination peptides of GnRH and HCG and my performance in both sports and my physique is much better than before, but i've seemed to have gotten a lot more violent than before. Yesterday night I punched a former friend of mine(cut contact with him) with an iceball repeatedly until his nose was bleeding, aswell my dreams are also really violent now, and last night I had a dream of murdering my family and me in the dream being unfazed by it, and in that same dream later on i punched a guy's stomach into a hole like in an anime. I've forgetten most of the violent details of my recent dreams over the past few days but they were more tame than this most recent one. Should i quit the peptides? I'm scared i'll turn into violent schizocel
