Where to get Testosterone Enanthate in the UK?

Here we will look at testosterone enanthate, which is one of the most popular testosterone medications in use today by clinics.

Testosterone Enanthate is more difficult to get in the UK than some other medications as it is under license in the UK with no generic options. This makes it much more expensive.

Luckily at OptiMale we have sourced a supplier which allows us to provide it at a reasonable price with the same pharmaceutical grade quality.

We are a legal UK-based TRT clinic which specialises in providing the cutting-edge of testosterone replacement therapy for men in the UK.

What is Testosterone Enanthate used for?

Testosterone enanthate is used in Testosterone replacement therapy (TRT) to replace the testosterone usually produced by men and to improve the symptoms of low testosterone.

It is injected either once per week or split into two doses and injected every few days depending on the individual and the best protocol as decided by a doctor.

Some men prefer this medicine to other alternatives for the reasons below.


Why use Testosterone Enanthate versus Sustanon?

Some people ask ‘why use Testosterone Enanthate if you have alternatives such as Sustanon which are more readily available?’

For some men, Sustanon is a good choice as it is injected less frequently than testosterone enanthate and acts quickly which makes men feel improvements almost immediately. Sustanon used to be the main compound used at Optimale. However, enanthate is now the medication of first choice for most men as Sustanon tends to cause more side effects and long term issues.

Lots of men notice that they get anxiety after taking Sustanon or have a more painful injection site after using it.

Sustanon can also negatively impact lipid levels and haematocrit. Both of which can lead to serious side effects if not controlled.

Other men get spikes in oestrogen levels from the propionate ester (a short-acting form of testosterone) in the Sustanon.

Sustanon contains 4 different esters which release the testosterone into the blood at different rates. This can lead to less predictable testosterone levels.

Testosterone enanthate has a smoother release profile than Sustanon, which reduces the amount of conversion to oestrogen in some men. This is because it has one ester which releases at a medium rate. It can take slightly longer to ‘kick in’ than Sustanon for this reason.

By dosing testosterone enanthate twice or three times weekly, there are less peaks in testosterone levels. This means that oestrogen, haematocrit and DHT levels are also controlled and result in less side effects overall.

When not to use Testosterone Enanthate

Testosterone enanthate should only be prescribed by a registered doctor. This list is not exhaustive.

As with all testosterone medications, there are potentially serious side effects if the medication is abused. It is also not suitable for certain patients based on their underlying conditions.


Testosterone increases red blood cell production. If you have a condition that causes this issue then supplementing with testosterone may raise haematocrit and haemoglobin levels too high.

As a result of this, the blood can get thicker. This may lead to a higher risk of heart attacks, strokes and other cardiovascular issues.

Women and children

Women and children should not use testosterone enanthate due to its virilising effects. This means that the testosterone causes male characteristics to develop. Women and children who take enanthate may notice a deepening voice, clitoral enlargement, early puberty, reduced breast size, early penile growth and infertility amongst other issues.

Metastatic prostate cancer

Whilst there is some controversy around whether testosterone replacement therapy causes prostate cancer (new research indicates it doesn’t), there is some evidence that removing testosterone prevents further growth. Therefore men with this condition should not start taking testosterone enanthate.

Kleinfelter’s disease

This genetic condition can cause low testosterone. Enanthate may be suitable for these patients but they need a specialist review by an endocrinologist before continuing with treatment.


What are the potential side effects of using Testosterone Enanthate?

As with all medications, enanthate has potential side effects. If used sensibly and under the supervision of a TRT specialist, enanthate side effects are easily controlled. However, there are some you should be aware of. The higher the dose, and if abused, the more likely and more dangerous the side effects can be.

1. Acne

Testosterone increases the production of sebum by the skin which can cause more spots around the shoulders and back. This may indicate your dose is too high.

2. Haematocrit levels

As mentioned above, testosterone increases haematocrit levels which can lead to a thickening of the blood. This may increase the risk of heart attacks and strokes.

3. Prostate enlargement

If testosterone levels are too raised then the prostate may become enlarged and cause issues with urination.

4. Injection irritation (PIP)

The area around the injection may become irritable or in very rare cases infected. Usually injection irritation is not a severe side effect and infection only occurs if proper sterility protocols are not used.

Some men notice irritation due to the Benzyl Alcohol content of the oil that testosterone enanthate contains. These men may need to try another option if they have a serious reaction.

5. Raised oestrogen/oestradiol

Testosterone is converted into oestrogen in the body by an enzyme called aromatase. Oestrogen is an important hormone for men’s health but in high amounts it can cause low libido, fatigue, water retention and makes men more emotional.

 6. Anxiety

Low testosterone can cause anxiety and depression.

However, raised oestrogen and testosterone can also lead to anxiety. If the enanthate dose is too high then some men experience this issue.

7. Hair loss

Testosterone converts into DHT which is responsible for androgenic alopecia.  This means that some men on TRT may notice accelerated hair loss. This can be slowed or stopped by the use of certain medications.

How to Inject Testosterone Enanthate

Testosterone enanthate can either be injected subcutaneously or intramuscularly.

Subcutaneous injections are the most effective for controlling oestrogen, reducing scar tissue and for safety. You can watch how to safely inject here.

Intramuscular injections are the more traditional way of injecting testosterone but have various downsides, including more scar tissue, more peaks in oestrogen levels and more risks.  You can learn more here.


What is the average dosing used for Testosterone enanthate?

 The average dose for testosterone enanthate is 100-150mg per week. However, this is very individual and depends on a myriad of factors.

For example, HCG (which is used alongside TRT) can affect testosterone levels – some men will produce more testosterone than others from using HCG and therefore may require a lower (or higher) dose.

Our TRT specialist doctors will work with you to ensure you have the correct dose to get you to the top of the normal range whilst controlling oestrogen levels.


Is it illegal to have Testosterone Enanthate in the UK?

Testosterone enanthate is a Class C controlled drug which means it’s not an offence to possess it, but manufacturing, supplying or exporting it without a licence is illegal, as is buying it online and having it shipped to the UK.

However, if you have a prescription through our specialist doctors we can legally provide medication through a partner pharmacy.

Any use of this medication should be supported by a GMC registered doctor such as one of OptiMale’s specialists.

What are the alternatives to Testosterone Enanthate in the UK?

There are several options if you are thinking about getting Testosterone replacement therapy (TRT):

1. Sustanon – a testosterone injection with 4 esters.  Some men prefer sustanon for its convenience. Other men feel better on the preparation.

2. Testosterone cypionate – a similar testosterone to enanthate with a slightly longer half-life and a less painful injection. This is a very popular choice.

3. Gonasi HCG 5000 IU – Italian brand of HCG which is used to increase the natural production of testosterone and maintain testicular function. It is recommended for all men on TRT. Some men use this on its own.

4. Testogel – this gel is rubbed into the shoulders, it is mainly for men who don’t want to inject.

5. Nebido – a long ester which is injected every 8-10 weeks.
