Mesterolone is an oral androgen (another name is 1-methyl dihydrotestosterone). Like dihydrotestosterone, mesterolone has great androgenic strength and just not sufficient enough anabolic strength. This is due to the fact that, like dihydrotestosterone, mesterolone is rapidly deactivated in muscle tissue to an inactive substance.
Mesterolone has an extremely high affinity for binding to plasma proteins such as SHBG (binding globulin in the sex hormones).This makes mesterolone enhance the activity of other anabolic steroids.
Among athletes, mesterolone is primarily used to increase androgen levels in the diet or in preparation for competition. It is well known for its anti-estrogenic effect, due to his own ability to antagonize the aromatase enzyme.
When taking Mesterolone, given are some of increases in muscle, even if minimal, more or less it’s about muscle hardness and density. It is known that androgen receptors are found in the muscle and in fat cells and therefore, the use of Mesterolone together with testosterone promotes muscle growth but also a loss of fat.
