I'm thinking about trying a cycle of Decka. I was just wondering if there are any heavy side effects like acne, attitude swings, and does it affect the penis? I was also told you have to stack it with something or else it won't work. Would stacking it with Winstrol be ok, or do you have to do something else. I heard people stack it with Test and Winstrol but I don't want to do both. Thanks.
