My friend is currently using test prop. On friday he hit his left cheek, as of yesterday it became swollen and painfull. It is not bruised. He said he aspirated, however when he pulled the needle out there was some blood on it. I think it could be 1 of 3 things. 1-i’ve heard prop hurts like a bitch, 2-he passed through a vein, 3-he’s getting an infection. What do you all think is the most likely scenario?
