Hormone levels were measured in patients with Klinefelter's syndrome after treatment with 100 mg mesterolone cipionate (twice monthly). There was no difference in plasma testosterone and FSH levels in treated and untreated patients. The basal and maximum LH levels were lower, but remained raised. The urinary excretion of testosterone as measured by liquid gaschromatography was higher in treated patients after treatment was discontinued.-From these results it is concluded that in spite of reported decreases of plasma testosterone during therapy with mesterolone cipionate this drug does not lead to severe impairment of the endogenous hormone production after discontinuing treatment.
Many bodybuilders favor the use of mesterolone during dieting phases or contest preparation, when low estrogen and high androgen levels are particularly desirable. This is especially beneficial when anabolics like Winstrol®, Anavar, or Primobolan® are being used alone, as the androgenic content of these drugs is relatively low. Mesterolone can be effectively used here to adjust the androgen to estrogen ratio upwards, bringing about an increase in the hardness and density of the muscles, supporting libido and general sense of well being, and increasing the tendency to burn body fat. It is also commonly used (at a similar dosage) to prevent gynecomastia when other aromatizable steroids are being administered, often in conjunction with 10-20 mg per day of Nolvadex.
