My wife noticed my temper is short fused and increased. Oily skin and some acne on my shoulders. A little pip the day after but it actually only lasts a few hours. 400mgs is alot for 1cc so you might cut with a small amount of eq or mast. Also I tried to go into quad but that shot did hirt. I have only pinned there a few times over 15 years and I think I will stick to the butt cheek.
