I was having the same problem on my current cycle. After the second week I couldn't take it anymore cause my ass hurt so bad I couldn't hardly walk. I split the injection into 2 shots - Mon. and Thurs. and it worked wonders. I still had a little soreness but nothing like before. Also, don't take the injections just before you are going to bed. I did this and it seemed like the juice just settled in all night and made the spot really sore. Good Luck!
