I'm a 6'3, 180-185 pound guy who can't pack on mass to save my life. Six months ago I purchased two supplements, D-Bol and Winni-V from SDI-labs. After about 6 weeks I noticed an amazing difference. My Chest, arms, neck, legs...h*ll everything was bigger! I had to stop because I was moving around from country to country but now I can get back to the gym. I haven't lifted in two months but I am back at it. The results were good for me. I wasn't EXTREMELY HUGE but I don't want that either. I am pushing for 205, lean and cut. IF you have any better suggestions let me know as far as supplements. Thanks.
