i'm with unreal on this subject of sd and carbs, the first time around i ate tons of carbs because i heard sd goes crazy for carbs, however carbs aren't my best friend and even though i grew at a good rate i did feel like i put on some fat, the next time around i still included carbs but didn't overdue it and was much happier with the reults, i gained roughly the same amount of weight....just the strength didn't seem to be as drastic
so i believe if carbs affect you easily then increase them but don't go too overboard, if your a naturally skinny person....carb up and let the weight fly
