Although Prolactin does not have as much of a direct importance to the anabolic steroid user as something like Estrogen does, there are a plethora of anecdotal reports of anabolic steroid using individuals who have used particular compounds and reported much higher than normal Prolactin levels. Many individuals have even provided their blood test results as anecdotal evidence to attest to this. However, there has been wild variation in the trends concerning the Prolactin issue with anabolic steroids, and much of this is due to the fact that there unfortunately does not exist as much research on many anabolic steroids as we would like, and so there is no solid clinical data from which we can draw conclusions (. the direction relation of a Progestin such as Trenbolone or Deca-Durabolin ( Nandrolone ) on PRL levels). Until the day that studies on such hypotheses are directly conducted, we will have to work with the data that science has currently provided us.
