Product Description:
Mesterolone is a methylated oral form of dihydrotestosterone (DHT). DHT does not convert to estrogen. However, in this methylated form, it will bind to the aromatase enzyme and prevent the formation of estrogen from testosterone. Reduced estrogen implies reduced estrogen side effects such as water retention and fat deposition. Mesterolone also has a high ability to bind with sex hormone binding globulin (SHBG) in preference over testosterone. The result is that when mesterolone is combined with testosterone, more free testosterone is available for anabolic activity. Mesterolone has been noted to be useful in maintaining libido in the presence of certain other steriods which negatively affect that. Mesterolone should not be used by females as it will have virlizing effects due to its androgenic property.
