Testosterone drugs are intended primarily for men with a low level of sex hormone testosterone (hypogonadism, or testosterone deficiency) and, in some cases, for women to treat breast cancer. Hypogonadism can be caused by genetic diseases, infections, autoimmune disorders and other problems, and leads to delayed puberty in boys, erectile dysfunction, depression and other behavioral changes and loss of muscle in adults. Testosterone is also used as an anabolic steroid in bodybuilding to induce muscle growth and increase power, although in some countries non-medical use of it is considered to be illegal.

Forms of Testosterone

Testosterone medications are produced in different forms: intramuscular injections, capsules, gels, creams, pellets that are implanted and buccal delivery system. Injectable testosterone comes in an esterized form: once the medication is in the bloodstream, it gets rid of the ester, slowly releases the hormone and sustains it on high level for up to several weeks.

Testosterone Injections

Here is a list of generic names of the most common injectable testosterone esters and their brand names:

  • Testosterone Propionate (brand names Testoviron, Testovis, Viromone);
  • Testosterone Enanthate (brand names Delatestryl and Tesamone);
  • Testosterone Cypionate (brand names Depo-Testosterone, Aveed, Andro LA 200 and Depandro 100);
  • Testosterone Undecanoate (brand names Andriol, Androxon, Aveed, Cernos Depot, ┬áNebido, ┬áNebido-R, Reandron 1000, Pantestone, Restandol, Virigen and Undestor);
  • Sustanon 250 (it’s the brand name of the drug that is a mix of four esterized testosterones: testosterone propionate, testosterone phenylpropionate, testosterone isocaproate and testosterone decanoate).

Other Forms of Testosterone

Capsules are taken orally. Creams and gels are applied on skin. Compared to other forms, these are painless and easy to use. Here is a list of the most common brand names of testosterone in gels in creams:

  • Androder;
  • AndroGel;
  • Axiron;
  • Testim;
  • Fortesta;

Implantable testosterone pellets, or implants (brand name Striant), are implanted under the skin of buttocks or lower part of abdomen. Like esterized testosterone injections, implants slowly release testosterone into the bloodstream and sustain its high level for up to five months.
