Esters are the bonding chemicals that allow artificial testosterone to work with your system. Chemically, they form from OH hydroxyls and -O- alkoxy groups. This list covers the most common forms of testosterone used in therapy with a quick primer on production. Testosterone cypionate lasts longer than other ester compounds.
The lengthy half-life owes to the octo-carbon bond. The effects of cypionate hit harder and last longer. This gives the most immediate and highest testosterone injection results. The compound stays in fatty tissue, which is a reason for direct intramuscular injection. You see effects within 2 days. After that, it levels off around 12 days and persists in the system for upwards of 21 days.
It takes 44 total days for cypionate to leave the system. So implied is the testosterone cypionate half life would be 22 days. During a treatment regiment, cypionate gets administered roughly every days. This makes it the most popular treatment option because it takes the least amount of time and effort to maintain levels. Testosterone propionate lasts the shortest of ester compounds. The total lifespan persists a maximum of 72 hours.
Testosterone, like other estrogen compounds, absorbs poorly and metabolizes quickly. Propionate leaves the system entirely by day The short duration of propionate makes it time-consuming.
It is the most work-intensive ester compound for treatment regiments. Injections need to be done daily to maintain levels and drop-offs occur in as little as 2 days after stopping. Propionate compounds are used by bodybuilders or athletes. It has a discernable effect in building muscle mass.
It also leaves the system fast enough to avoid doping test issues. Enanthate works as a middle ground between cypionate and propionate. Effects hit between 24 and 48 hours, like cypionate.

Testosterone enanthate is also known as testosterone heptanoate. It is an anabolic and androgenic steroid AAS drug used to treat low testosterone levels. Anabolic drugs work by building muscles, while androgenic means it enhances sex characteristics usually associated with males. This drug has been used in medical procedures since the s. It is known by a number of brand names, including Androfil, Depandro, Testrin, and Testro.
As a schedule III drug , testosterone enanthate is available by prescription only. This article will explain how and why the drug is used. It also offers information about side effects and interactions with other drugs, and answers questions about related cancer risks from using it.
Testosterone enanthate is classified as an AAS for two reasons. It is both a synthetic drug derived from the testosterone hormone and a testosterone pro-drug. This means it stimulates the body to make its own testosterone. With that being said, it has stronger androgenic effects and only moderate anabolic effects. The drug can be used for testosterone replacement therapy TRT in cisgender cis men with hypogonadism , or the decreased ability to make testosterone. Causes of this condition include injury, infection, and cancer of the testes.
Radiation and chemotherapy can also cause hypogonadism. So can disorders such as Klinefelter syndrome and diseases of the hypothalamus and pituitary gland, two brain regions that stimulate the testes to make testosterone.
Testosterone levels in cis men can drop steeply after the age of 50, leading to a condition known as andropause. Older cis men with symptoms of andropause, including the loss of vigor and a lower sex drive, will often benefit from TRT. This drug can also be used for hormone therapy in transgender masculine people. Other uses include treatment for delayed puberty in cis boys, and in metastatic breast cancer when it has spread in those who are postmenopausal.
The drug is also sometimes used, controversially, as an anti-aging therapy in older cis men. Testosterone enanthate is a clear or yellowish fluid that comes in a 5-milliliter ml glass vial. It is injected into a buttock muscle every one to four weeks. To avoid large changes in hormone levels, and the mood swings that may come with them, lower doses are often used over shorter intervals.
The active drug, which is suspended in sesame oil, has a sustained release period of two to three weeks. The dosage may vary by individual but it is typically used as follows:. While testosterone enanthate is sometimes used interchangeably with testosterone cypionate depo testosterone , the latter is approved only for treating hypogonadism.
Testosterone enanthate is a steroid with both anabolic and androgenic properties. By the end of the first year of treatment for low testosterone, here is what to expect from testosterone injections:. The results of testosterone injections can be truly life-changing for someone who experienced debilitating symptoms associated with low testosterone.
Testosterone pills go to the stomach, where the digestive enzymes begin to tear apart the medicinal properties of testosterone. The balance of testosterone pills winds up in the liver, where toxicity can build up and cause health problems. We know that most are eager to see and feel positive changes, which is why the question — when will I see results from testosterone?
Those patients who choose not to use injections tend to opt for testosterone gel or cream. The benefits may come a bit slower because, unlike testosterone injections where the entire dosage is readily absorbed into the bloodstream, there is no way of knowing exactly how much testosterone is absorbed through the skin. The initial benefits of improved sex drive, better perception of quality of life, and reduced anxiety will most likely still occur during the first month — just perhaps not to the same degree.
Some men and women do feel effects of testosterone quicker with the gel or cream. There is no way of knowing until the treatment is started. Low testosterone can be easily diagnosed with a simple blood test and treated with testosterone replacement therapy to bring your testosterone levels back to normal.
The testosterone replacement therapy options available are:. Performance tests done at the end of this period showed the hormone had improved muscle size and strength in those doing strength training, and to a lesser extent in those who did not exercise.
The only other comparable study, in , looked at the effects of different doses, but the volunteers were only tested after 20 weeks. In the latest study, Weatherby monitored the performance of 18 male amateur athletes over a six-week training regime. Nine were given weekly shots of testosterone enanthate at a dose of 3. Those conducting the tests did not know who was receiving testosterone and who was on the placebo.
Unsurprisingly, given the low dose and short duration, no dramatic effects showed up. The personality tests suggest that those on testosterone became less empathic and considerate towards others, and the activity of their immune systems seemed to decline slightly, but there was no significant effect on mood.
There was, however, a dramatic improvement in the performance of the athletes taking testosterone. The most unexpected finding was that the greatest increases in muscle size and power occurred just three weeks into the trial see graphics. Most professional athletes can expect to be tested from once every two years to as frequently as 20 times a year, depending on the level at which they compete.
