How Are HGH and Testosterone Made?

Signs and Symptoms of Low Testosterone in Males

Both the Human Growth Hormone (HGH) and the testosterone used in hormone replacement therapies are prescription medications. That means HGH and testosterone are drugs manufactured by pharmaceutical companies.

The HGH used for growth hormone replacement is some form of the drug known as somatropin. Prescription testosterone injections are manufactured in different forms of testosterone known as “esters.” The most common “ester” of testosterone is testosterone cypionate, which is also known as DEPO-testosterone.

These drugs are used to treat growth hormone deficiencies (GHD) or low testosterone. Many times they are used together, because many times aging patients have low levels of both testosterone and HGH.

How Is HGH Manufactured?

How Is HGH Manufactured

HGH is produced by the pituitary gland, a small gland at the base of the brain. Many years ago, the HGH used for growth hormone replacement was extracted from the pituitary glands of cadavers. However, in some cases this caused the rare but fatal, Creutzfeldt-Jakob Disease (CJD), the “human” version of “Mad Cow Disease.” In the mid-1980s this lead to a total ban of HGH manufactured this way.

A little over six months after the ban on the natural source of HGH, the FDA gave its first approval of a synthetic form of HGH, made from recombinant human DNA. This process ensured it was an exact duplicate of the HGH made by your pituitary, but it eliminated the risk of the deadly brain disease.

It was made by a company called Genentech, and sold as the prescription drug Protropin. Protropin came off of patent, and is now known as the generic drug somatropin. Today, along with the generic, there are many brands of prescription HGH, made by several different pharmaceutical manufacturers. These are all some form of somatropin. They differ mainly in their available doses, and delivery methods.

Testosterone used to treat patients for low testosterone is manufactured as different esters. An ester is simply a name for an organic chemical compound that is formed from the reaction between a carboxylic acid and an alcohol. The different esters of testosterone, differ only in the position of carbon and hydrogen atoms in their chemical structures. The most commonly prescribed esters of testosterone are testosterone cypionate, testosterone enanthate, and testosterone propionate.

Because of their different chemical properties, the esters differ mainly in how well they are absorbed by the body and how long their effects last. You doctor will prescribe the type of testosterone injections that fits best with your symptoms, goals and lifestyle.

There are several different name brands of each of the esters. The most commonly prescribed ester of testosterone is testosterone cypionate. The most common brand of cypionate is Depo-Testosterone. It is popularly referred to as “Depo” or a “Depo Shot.” Depo was the first testosterone injectable approved by the FDA. It has been produced by Pharmacia and Upjohn since 1979.

HGH and testosterone are both prescription drugs manufactured by pharmaceutical companies.
