TESTOSTERONE CYPIONATE INFORMATION here is an interesting fact is that testosterone was actually the first ever synthesized anabolic steroid. Specifically related to testosterone Cypionate, it is a slow-acting, long-ester, oil-based injectable testosterone compound that is commonly prescribed for the treatment of men suffering from hypogonadism or an array of other possible testosterone imbalance issues.

Testosterone Cypionate first appeared on the U.S. prescription drug market during the early 1950’s, as Depo-Testosterone by Upjohn, now Pharmacia & Upjohn. Now, because testosterone Cypionate is so molecularly similar to another ester of testosterone called Enanthate, which only has a slightly shorter ester, it wasn’t very well globally recognized and, furthermore, has been acknowledged as an American medication.

Anabolic steroids, derivatives of testosterone, have been used illicitly and are now controlled substances. Men participating in these type of programs appreciate the rapid results and the extraordinary muscle growth experienced from administering these substances; even at the end cost of eventually irreversible endocrine system malfunction.

Testosterone, like many anabolic steroids, was classified as a controlled substance in 1991.


Before providing any more testosterone cypionate information, let’s begin by explaining esters: An ester is described as any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids.  For the most part, esters are derived from carboxylic acids. The addition of a carbon chain (ester) attached to the testosterone molecule controls how soluble (how quickly it will dissolve and exit your body) it will be once inside the bloodstream. The smaller the carbon chain, the shorter the ester, and the more soluble the medication.

A smaller or shorter ester will have a shorter half-life, which is basically a depiction of the cycle of a medication’s functionality time while inside the body. Conversely, the opposite can be said of long carbon chains, such as Cypionate, which both acts slowly within the body and exits the body equally as slow. Studies and further testosterone cypionate information research show that participants of injectable Testosterone therapy may sometimes administer more than one ester of testosterone at a time. This option allows patients to manipulate their testosterone levels more efficiently, helping to avoid peak and valley levels and their associated side effects.

Testosterone Cypionate has a 7-day half-life:

  • This means it is in your body for 14 days
  • The first 7 days it’s working on increasing your levels
  • The last 7 days it’s working on exiting your body

The good and the bad

The Good:

The Testosterone Cypionate information that patients appreciate most is that, due to the longer carbon chain (ester), it only has to be administered every 7 days in order to catch it before it begins the process of exiting the body. Though AAI Rejuvenation Clinic does not use the standard, intramuscular needle tips that most other clinics use, as ours are significantly more comfortable to utilize, most patients would still rather administer their testosterone injections as least amount of times as possible.

The Bad:

The longer a medication stays functioning in the body, the higher the potentiality for side effects to emerge. Some side effects may be:

  • Acne
  • Bloating or water retention
  • Irritability
  • Weight gain

The good within the bad:

AAI Rejuvenation Clinic’s physicians will not organize a program that includes only Testosterone, regardless of the ester. Participating patients are prescribed and an array of accompanying nutraceuticals to help ensure side effects are kept at bay. These medications are individually prescribed based on the patient’s file details. Moreover, our patients will also receive intermittent blood tests to ensure that everything is running according to plan on your quest to reach your health and wellness goals.
