OMG the crap in these replies... bro science at its best.
You need to do the following, your getting to much testosterone bound up by SHBG, so first you need proviron 100mg ed for 5 days then drop to 50mg. This will free up test, and give you a libido increase.
Second, the deca is faster acting than the test, so its negative affects on libido are noticeable first. You are running a low dose of deca, you do not need all the bunk suggested to combat prolactin, all you have is an imbalance in your hormonal ratios.
Trust me just use the proviron and I guarantee you will see a change after 4 days, feel free to PM me and I will help out with anything you need.
Kindest regards RS
