Pharmacies sell a variety of preparations of natural testosterone such as lozenges, topical gels, topical creams, intramuscular injections, and oral capsules. Each dose is highly individualized because excess amounts can lead to extreme liver problems or cancer. Those very serious risks are the reason it is so important to go to a doctor who specializes in hormone therapy or anti-aging solutions. The Testosterone pills have the best method of delivery. Only a professional with experience can determine the proper dose and preparation that will be right for you
