What is Testosterone-Cypionate?

Testosterone-Cypionate the form of testosterone provided most often in testosterone therapy. It’s a specific form of testosterone, slightly different than what human bodies produce on their own, but for reasons essential to its administration to the body. To maximize the benefits of male hormone therapy, testosterone Cypionate is one of the types of testosterone a person can inject or get in a gel. There are very specific reasons why this form of testosterone is most popular for therapy.

Testosterone is the substance produced in human bodies that regulate the expression of male characteristics. It also promotes healing and mental well-being. It’s a relatively small organic molecule that isn’t a protein or peptide-like HGH, but instead is very similar to cholesterol or Vitamin E; it’s a hydrocarbon ring, an oil-soluble type of substance. It travels to all parts of the body through the blood. In males, it’s produced by specific cells in the testicles, triggered by signals from the brain, which also travel through the blood. The amount of testosterone in a man’s blood correlates directly with the masculine traits he exhibits, i.e., being hairy, being strong, and having physical and mental energy.

The human body produces the natural form of testosterone.

When humans produce testosterone in their body, the specific type of testosterone that’s produced is just plain testosterone. No additional fragment is stuck to it, as in the case of testosterone-Cypionate where what’s called a Cypionate moiety is stuck to one end of the testosterone molecule.  Technically, human bodies don’t produce the Cypionate form, but doses of testosterone injections are taken in the Cypionate form as opposed to just plain testosterone by itself.

what is testosterone cypionate used if the body doesn’t make that form?

When testosterone-Cypionate is administered in the form of a gel or injection, the body converts the Cypionate form into plain testosterone. There are enzymes called esterases that target the connection between the Cypionate moiety and the testosterone molecule, breaking off the Cypionate from testosterone, leaving plain testosterone in the form that the body uses it. These esterases yield the same molecule of testosterone the body produces. This is why testosterone-Cypionate is referred to as bio-identical testosterone, putting it into the body is essentially equivalent to increasing what the body has made at one time and is already capable of using, natural testosterone in the form the body uses it.

A time-release effect provides stable hormone levels.

The reason the Cypionate form is administered, as opposed to just plain testosterone, is to provide a time-release type of effect. Making the molecule more oil soluble tends to stabilize the blood levels of free testosterone, releasing more gradually over time. If free testosterone were injected directly, we’d observe a peak in its blood concentration immediately after injection followed by a rapid decrease thereafter. By injecting the Cypionate form, more of the testosterone gets absorbed by the body’s fatty tissue to be released more gradually over time. It gets dissolved into the blood more slowly, and the blood concentrations of testosterone Therapy resemble a more stable pattern useful for therapy. Instead of having to get multiple injections daily, with testosterone-Cypionate you can instead space out injections on the order of weeks.

As we discussed in our previous blog post about the different forms of testosterone, testosterone-Cypionate is only one out of several that are included in therapeutic doses. The dosage and forms that are prescribed to anti-aging patients differ from patient to patient. Whatever form is prescribed, it’s important to follow dosage instructions as precisely as possible. Both the form and the dosage times are chosen together to provide the most stable, consistent hormone levels possible, getting the most benefits with the least side effects.
