Due to its chemical structure nandrolone is weakly exposed to aromatase (only 20% of the aromatizing activity of testosterone). However, not estrogenic effects are its main concern: nandrolone has a potent progestogenic activity (20% of progesterone). While binding to progestogenic pituitary receptors nandrolone causes increased production of prolactin, which in effect is very similar to estrogen: its effect presents in reducing testosterone production, increasing fat mass and in gynecomastia. To prevent these side effects prolactin inhibitors (cabergoline) shall always be at hand when on nandrolones cycle.
Even if a drug is rated low in estrogenic activity, unwanted and often unpleasant side effects are possible.
