I'm in my 5th week (kind of 4th since I was sick all last week and didnt take any since I wasn't in the gym), but I have had people say I look bigger and decided to take some measurements. My shoulders and chest are almost an inch increase in size, and my thighs have increased in size about an inch. I also switched up how I was lifting about 3 months ago so take it for what its worth..
