I started my first cycle 4 weeks ago and was noticing great gains at 500ml a week. Im not sure if i am over reacting but it seems like my nipples are puffing out a little bit and am worried im getin bi_ch tits! They felt a little sensitive about a week ago and am worried what I should do? I know that generally you need blocker but i dont have any on hand and am waiting for a call back. Am I over reacting ? What does everyone recommend?? Can this hapen from skipping about 5 days of working out since I was just on vacation and didnt have access to weights?? Please help...
