prolactin based gyno typically involves lactation.
if you're taking a 19-nor based androgen and get gyno, then it would be wise to treat for elevated prolactin. well, it would be wise to take a preventative dopamine agonist, in the first place....
however, it merits mentioning that elevated E2 can raise prolactin as well. it's not common, but regardless, is pretty easily treatable (and preventable)....
most modern versions of tren aren't known for prolactin, but I believe either Fini or Parabolan was.
anyway, if you're dealing with gyno while on-cycle, you could take raloxifene for the actual gyno. then an AI to address elevated E2, and a DA for the elevated prolactin.... another option while on cycle is andractim (a topical DHT cream) as well.
