Has anybody gotten stretchmarks on their biceps? I just recently got wat looks like red stretchmarks on my bicep near my shoulder/arm pit. I dont know if these are stretchmarks or not since i dont know wat they look like when they first appear, but they look sorta pinkish-red colored and when i rub my finger on it, it feels kinda like an indentation is there. I worry because besides lookin kinda nasty, it looks like i might be getting them in the lower part of my bicep too (only in my left arm too). Me and my friends think that it may be caused by water weight since my BF% is like around 12 or so and ive been taking creatine for a couple months, and according to my friends, i look like I have mad water. Are these stretchmark and is it possible to get rid of them by droppin my BF% and water weight (im going to my cutting cycle in a month and a half)
