You're very very light to have done 5 cycles. You're going to have to be more focused on eating and that's no joke. You know I'm really not trying to bust your balls. You really do need to concentrate on it because at your size and 5 cycles under your belt, you should much much heavier. So this time, put your time into eating. With that said, I'd consider test only or test/deca. I'm really uncomfortable with actually advising you on which direction to go because anyone who's willing to run AAS needs to be as serious about eating/diet as they are about training and anabolics. Please go to the diet section and get advice from there as well. Good luck to you.
