I'm just starting my fourth week of my first tren cycle 100mg eod. Stacking with test/mast. I am still wondering about sides as I have had none other than occasionally waking up a couple times a night. At first I was thinking it was bunk till I experienced the cough. So far, I can see nominal strength but def hardening up of body. I got it from a reputable source so I don't want to think its under dosed either. Also, I heard since its ace, the pip is crippling but again, hardly hurts at all.
