12 or 16 Week Test E Cycle: Which One to Choose?

Testosterone Enanthate has a strong reputation for improving physical performance and strength. It works well on its own and in combination with other anabolic substances in a cycle.

But 12 or 16 week test e cycle which cycle should one choose?

A 12-week cycle is sufficient for muscle gain and performance enhancement. However, for professional bodybuilding or competitions, a 16-week cycle is recommended. Most Test E cycles use 600 mg to 1000 mg dosages. The dosages may seem high, but it should not be an issue for an intermediate user.

That only tells part of the story on this subject. There’s more to come! So please allow us a few minutes to go through everything with you.

12 or 16 Week Test E Cycle: Which is for Whom?

It is preferable to take a standard 12-week cycle, reset, and then repeat the process. It will produce a more desirable outcome. Some people opt for a much longer cycle of 20 weeks.

But as mentioned previously 16-week cycle is the best for professional bodybuilding and competition. The most progressive cycles include doses ranging from 600-1000mg, whether they are 12 or 16 weeks long.


Let’s look at how the dosage varies per cycle: 

12-Week Test E Cycle

A 12-week beginning cycle includes weekly dosages ranging from 250mg to 500mg. It gives the newcomer a solid start. Side effects should be minimal at this dosage. 

12 Week Cycle Dose (For Beginner)

A dose of 500 mg of Testosterone Enanthate is given weekly during this cycle. Along with this, Deca-Durabolin at 400 mg per week is used for the entire 12 weeks. 

This cycle also includes 25 mg of  Dianabol weekly for the first four weeks. This dose gives the bulking and strength stack a boost.

12 Week Cycle Dose (For Intermediate)

Advanced cycle like this is not recommended for beginners. You need to take 500 mg of Test E per week. This will continue for the entire 12-week period with 0.5 mg of Arimidex.

Additionally, you need to take 40 milligrams of Dianabol per day for the first 6 weeks. You can split these doses throughout the day. From week 7 to week 12, 100 milligrams of Trenbolone is mandatory. You can take this dose every other day.

After the 12-week cycle is completed, PCT (post-cycle therapy) is required from week 14 to week 16. For the first ten days, you should take 100 mg of Clomid each day. This amount will be reduced to 50 mg each day for the next ten days.

16-Week Test E Cycle

This 16-week cycle is normally reserved for individuals who have prior experience with the test E cycle. PCT is mandatory for this option, which will begin two weeks after the last dose for enanthate.

In the case of propionate dose, it will begin after three days of the last injection.

16 Week Test e cycle dose (Intermediate)

3x10ml (250mg/ml) vials of Cypionate or Test E are required for this cycle. In addition, 3x10ml (150mg/ml) Deca vials and 100x10mg (200x5mg) Dbol tablets are required.

From week 1 to 6, take 25-35 mg of Dbol per day. Along with this, take 300 mg of Deca and 500 mg of test E per week from week 1 to 15. 

After that, continue on a 4-week PCT with 0.5mg of Arimidex each day. Two weeks following your last injection, you should begin your PCT. Clomid doses for PCT  will be exact for  the 12-week cycle’s PCT.

Benefits of Using Test E Cycle

The outcomes of different Testosterone Enanthate cycles are more or less similar. Long-time users are familiar with the advantages, but if not, here’s what you can expect.

Faster and Bigger Muscle Growth:

The weight of lifting huge weights causes the muscle tissues to break down. Resting allows your body to rebuild those tissues. These are not only fixed but also enlarged to manage the heavy loads being lifted.

That is a natural process, but it takes a long time. But with testosterone enanthate, you can easily speed it up.

Reduced Muscle Wastage:

Muscle waste is referred to as catabolism. Lifting weights and working out is beneficial to your body, but only if the nitrogen level is adequate.

The proper balance of oxygen and nitrogen is critical to preventing muscle loss and shrinkage. Testosterone E ensures that your body creates the ideal environment for muscle growth.

Muscle Endurance Boost:

Muscles must be robust, ripped, firm, and toned. That’s a challenging task that requires cellular level fitness. Testosterone enanthate can do this by raising your blood cell count.

Test E enters your system and causes a chain reaction. This leads to an increase in blood cells. Your oxygen level rises as the number of cells in your body increases.

The greater the supply of oxygen, the more it will reach your muscles.

Recovery of Muscle Tissues & Faster Healing:

Testosterone Enanthate significantly boosts your body’s ability to repair when ingested. You will be able to lift weights and work out for a long time without being exhausted.

The amount of testosterone you take affects directly the results you get. The benefits will be more obvious as the dosage and cycle length increase.

However, a large dose might cause negative effects, so start with the lowest amount possible.

Common Side Effects and How to Prevent Them

Both 12-week and 16-week cycles show some side effects during and after it’s been taken. People have different levels of tolerance to almost any hormone replacement.

So there will be a wide range of side effects that come with the replacement treatment. However, the following are the most common.

Water Retention and Man Boobs

It is the most prevalent enanthate side effect. The reason for this is that testosterone enanthate has a propensity to raise your body’s estrogen levels.


When your oestrogen levels rise, you may have water retention and gynecomastia. Anti-estrogen medicine is one of the techniques to combat this.

High Cholesterol & High Blood Pressure 

This is a common side effect at high dosage levels, but it is tolerable. All you have to do is eat a balanced diet and keep an eye on your blood pressure.

There should be no major issues if you maintain a healthy diet.

Acne and Hair Loss

There’s really not much you can do here except reduce the dose. According to studies, people with a genetic predisposition are more likely to have this condition.


Thus blaming testosterone enanthate isn’t totally accurate. The male body is naturally adapted to testosterone enanthate. Only the higher doses used for bodybuilding and performance increase the side effect.

PCT for Test E Cycles

PCT is the most critical aspect of the entire procedure, whether you are doing a 12-week or 16-week cycle. It tries to stabilise and restore a user’s hormones after a suppressive steroid cycle has been stopped.

When a person stops taking anabolic androgenic steroids, their natural testosterone production is reduced, sometimes drastically.

Furthermore, the levels of steroids in their blood are constantly decreasing, leaving the user in a very destructive state post cycle. This may affect their capacity to preserve muscle growth gained while on cycle.

Final Verdict

According to experts, even if you do everything correctly, your progress will slow down. Around 14 weeks, it will come to an end. 

It is preferable to perform a standard 12-week cycle, reset, and then repeat the process. It will produce a more desirable outcome. After 12 weeks, the sleep, diet plan, and training  are usually no longer effective. 

However, depending on your age and goal, you must ultimately determine which cycle is ideal for you.


Does Test Enanthate Cause Gynecomastia?

Yes, it can. All testosterone steroids can convert to estrogen and elevate estrogen levels, causing gynecomastia. While taking testosterone enanthate, you must utilize anti-estrogen medicine to decrease or avoid gyro and other estrogen side effects

Can Testosterone Enanthate be Injected Once a Week?

With an 8-day half-life, testosterone enanthate can be injected once each week. To maintain optimal levels of the steroid, however, split the dosage into twice-weekly injections. 

Is Testosterone Enanthate harmful to the liver?

No, injectable testosterone enanthate is not known to be harmful to the liver. Studies on testosterone indicated that even at extremely high dosages, it did not harm the liver. Testosterone enanthate still comes with other health risks so must be used with caution.


So, 12 or 16-week test e cycle which one should you choose? We hope this article helped you to get all the answers to this question. 

Now you can easily  decide if you want to go for a 12-week cycle or 16 Week cycle. Remember, there are always some great alternatives in case of steroid cycles. 

Until next time, Good Luck!!
