What is Testosterone Enanthate?

Testosterone Enanthate

Testosterone enanthate or ‘Test E’ is a mid to slow-acting ester of injectable testosterone. Test E was designed to provide a steady release of testosterone into the bloodstream once injected into muscle tissue.

After injection test levels rise over two weeks, the half-life of test e is stated at around 14 days. Therefore athletes will often inject it every 5 – 7 days to keep a steady supply of testosterone in their body.

Testosterone Enanthate is often one of a few ‘go-to’ steroids for bodybuilders and athletes. It is proven time and time again as a reliable and effective muscle builder.

New users can often expect to see significant gains in muscle mass and strength on cycle. For more experienced users the effects can be less exaggerated, however, still substantial.

Testosterone E 

Test E is often supplied in vials of 250mg. Depending on the country of origin, you can also find it in 50mg/ml, 100mg/ml, 200mg/ml and 250ml/ml dissolved in a carrier oil. 

Often used in HRT and the animal market testosterone enanthate can be found in pharmaceutical grade and also manufactured by many underground labs.

Testosterone Enanthate Price

Prices for test e can vary depending on where you purchase it. If you have a prescription, the cost can vary.

An average price range for purchasing from an underground lab can be from £25 per 10ml vial up to £40.

Testosterone Enanthate Cycles

For many bodybuilders and athletes, testosterone is often the ‘base’ of the cycle. For a beginner, the most used and recommend steroid cycle is injectable testosterone injected once or twice weekly for around 12 weeks.

When running a cycle 400mg – 600mg per week is recommended and will increase muscle mass and strength. 

Testosterone is quite versatile in the fact that it can be run as a ‘bulking compound’ and a ‘cutting compound’. Testosterone is a very effective androgenic steroid and often is ran on its own, successfully. 

However, testosterone can be ‘stacked’ with other steroids for a more synergistic effect.

E.g. A proven and favoured lean mass and strength building cycle is 500mg of testosterone and 300mg of Tren E.

What Are The Side Effects of Testosterone Enanthate

Any drug can have side effects and steroids are no different. Side effects of testosterone can come in various forms and are usually more prevalent for people who run continued length cycles or use more substantial doses.

Side effects from steroids can affect the cardiovascular system, estrogenic and androgenic. When using anabolic/androgenic steroids, it is essential to understand the risks associated with the use and also how to minimise the chances of them occurring. 

It is important to note that not everyone will experience side effects from steroids. It is essential to know and understand the risk associated with them, though. 

We can break down the side effects of steroids into the following subjects;

  • Estrogenic side effects
  • Androgenic side effects
  • Cardiovascular side effects
  • Hepatoxicity
  • Natural testosterone shutdown

Androgenic Side Effects

Testosterone is the male sex hormone. An androgen which is responsible for what makes men, men. High levels of testosterone in the body can often result in more androgenic based side effects including; oily skin, acne, increase in body and facial hair growth.

If you have baldness in your family using testosterone can often increase the rate at which you may lose hair and an increase in male pattern baldness. 

Testosterone can also have an impact on the prostate gland. Users have reported prostate enlargement while on cycle. This can go down once steroid use has been stopped.

Estrogenic Side Effects

The aromatise enzyme can aromatise excess testosterone into estrogen. When on a cycle using large doses of testosterone can cause this to become more prevalent. Some people are more prone to testosterone being converted into estrogen.

Estrogen is the primary sex hormone for females. This can cause an abundance of unwanted side-effects in men.

Estrogenic side effects of testosterone can include water retention, an increase in body fat and gynecomastia. When using testosterone, athletes will often run either Nolvadex to stop estrogen binding to fat tissue or an Aromatize Inhibitor (ai) like Arimidex or Aromasin to reduce the amount of testosterone which gets synthesised. 

It should be noted people with higher body fat have often been shown to suffer from estrogenic side-effects more so than people with lower body fat. 

Cardiovascular Side Effects

Steroids can increase muscle mass as well as causing the user to hold more ‘water weight’. This additional weight is often built up in short spaces of time and can result in added strain being put on the heart and organs.

Testosterone can affect cholesterol levels by reducing HDL or ‘good cholesterol’ and increasing LDL ‘bad cholesterol’.

This shift, over time, can result in the hardening of the artery walls and higher levels of fat in the bloodstream leading to strokes, or heart attacks if left unchecked and untreated.

The increase in muscle mass and water weight can also lead to higher blood pressure which can again, affect the heart and kidneys.

Using testosterone can also affect your blood ‘thickness’. Testosterone therapy increases red blood cell count and can lead to polycythemia which is the increase of haemoglobin and hematocrit. 

Steroid users will often have multiple blood tests per year to check for danger markers. More often than not donating or letting blood every couple of months if enough to keep blood-related issues arising. 

Testosterone Enanthate Effects On The Liver

 Test e alone often has little to no effect on the liver, unless users are suffering from a pre-existing condition. 

When taken in conservative doses, it is highly unlike to experience hepatoxic side effects caused by testosterone alone. 

Natural Testosterone Shutdown 

Using any form of steroid will lead to the suppression of your natural test production. This often returns after the cycle has stopped. In rare cases or when users have been on cycle for prolonged periods, people can be shut down permanently or suffer from low testosterone levels for many years.

PCT ancillaries such as HCG can help keep the testes stimulated and producing natural testosterone. It is usually taken as a part of a PCT (post cycle therapy).

FAQs for Testosterone Enanthate

What does testosterone enanthate do to your body?

Injecting test e into your body will increase your bodies testosterone levels and everything associated with higher levels of testosterone in your system. Higher levels of test can lead to muscle increase, strength increases a greater sense of wellbeing and more.

How long does it take for testosterone enanthate to kick in?

Essentially any steroid ‘kicks in’ right away. However, most users will start to feel a greater sense of wellbeing and experience more intense pumps at around week four and onwards.

Four weeks is typically how long it takes for testosterone to reach peak levels in the bloodstream.

How many times a week should I inject testosterone enanthate?

Testosterone enanthate is recommended to be injected twice per week. Following a Monday – Thursday injection schedule allows testosterone to build up while keeping hormone levels stable to reduce unwanted side-effects.

Can you drink alcohol on testosterone enanthate?

Yes, but why would you? If you’re using performance-enhancing drugs then it is likely you are eating clean, training hard and focusing on building a better, stronger and leaner body. Drinking alcohol probably isn’t ideal on any cycle.

Now, if you do intend to drink try to keep it to a minimum. The odd drink shouldn’t cause too much of an issue to otherwise healthy individuals.

How long can you stay on testosterone cycle?

How long is a piece of string? Many users will run the ‘blast and cruise’ method of cycling. Blasting and cruising involve running a cycle and then cruising on a maintenance dose of testosterone before running another blast.

The cruise phase could be 8 – 16 weeks or more. Don’t forget when people are prescribed testosterone for TRT or HRT they are pretty much on it year-round for many, many years. The important thing is to get regular health checks.


Testosterone enanthate is a great choice of steroid for new and more experienced steroid users. With the versatility of being able to work as a cutting and bulking performance enhancer, it is no wonder it is often used as the base for many athletes.

It makes a great choice for a first steroid cycle. Keeping steady hormone levels is important to manage side effects. The half-life and release nature of test e means that testosterone levels will steadily rise and fall over time without sudden jumps or drops. 

If you’re looking for an effective mass and strength builder with little side effects then test e makes a great choice.
