Alphaviron (methyltestosterone) is an androgen, or male hormone, used to treat men and women with hypogonadism, or low levels of testosterone. The 20mg tablets come in a 50 tablet bottle and are taken orally, typically once or twice a day depending on the prescribing doctor’s instructions. Alphaviron acts to correct testosterone deficiencies and helps to restore normal hormone balance. Possible side effects may include changes in libido, nausea, vomiting, headache, and a decrease in red blood cell count. It is important to note that the therapeutic effects of this drug may take several weeks or longer to be apparent.
