I've never measured before, but I thought I would just for this thread. My arms are pitiful: 15 1/4" left, 15" right. I'm 6 foot, 200 pounds, and 15% bodyfat. I have absolutely no peak, so that doesn't help.
I just started cutting too, so I will probably lose a tiny bit on each. Oh well, my arms have always been my weakest body part anyway. My chest and shoulders make up for it though. They are a testament to the fact that I can bench press 265 yet only deadlift 295 x 3 and full squat 245 x 2. As well, my "top 4 abs" are visible unflexed at 15% bodyfat, so that is a plus as well. You take what you can get.
