Steroids Underweight guy wants to run masteron to tighten further

[zupoafer]

I'm a skinny guy with abs. I've got a four- or six-pack, depending on how much water retention I have that particular day. I would like to tighten up my waist more. I currently have about a 30-inch waist. I would like to get it down to 26 or 27 inches. I'm six foot two and approximately 170 lb. How much masteron would you recommend? I'm 24 years old.
