Prolactin is a hormone. NIH researchers have conducted studies on prolactin and determined that it fuels PCa (in particular more aggressive or advanced PCa).
My prolactin baseline level was 7.7 mg/ml. In an effort to reduce prolactin I started taking .5 mg/wk of cabergoline. My latest blood measurement of prolactin was 1.2 ng/ml. I think that might be a little too low since prolactin is involved in some necessary bodily functions, so I am reducing my cabergoline a little. My target range for prolactin is 1.5 – 4.5 mg/ml.
As a bonus my bodyfat dropped dramatically within a week after I started taking cabergoline (started 03/23/2020). Bodyfat is the red line.
