Nitrogen retention symptoms and conditions

I've been taking a little more than somebody normally should. I'm taking 100-200mg daily orally. sometimes I'm taking up to 300mg!! I'm seeing exceptional results in muscle gain, with no bloating or moon face of course. The positives is good muscle gain, negatives: really bad depression, mood swings almost anything can irritate me especially driving around town, I feel i want to kick everyones ass, I have absolutely no sex drive, I took Test Cypionate before and this made my sex drive uncontrollable, winny does the opposite. I'm only taking winny and large amounts for dieting i have lost a lot of fat and im getting pretty big but most people would need to take large amounts like im taking to see results, i've noticed injecting works better for nitrogen retention (pump). Also some acne none on face just back. overall im gaining great muscle gains, but I really would rather take Test cyp, because i have severe depression because of winny and like i said my temper is really bad. If I didn't have a lot of self control right now I'd prolly hurt someone but one must remember to be mature enough while taking a powerful hormone such as winny.
