Dosage Guide: ON and OFF cycle

When to use ON and OFF cycle:

  • When you need to optimize your gains or when you need to achieve your desired results.
  • Suitable for amateur or professional bodybuilders, athletes or anyone looking to optimize their health goals.

ON and OFF cycle Guide:

  • 4 weeks on and 1 week off

Note: For bodybuilders, athletes, competitive sports or if you want to maximize your gains, you can consider adjusting your dosage as follows:

  • Week 1 – Week 4:  200 mg/day taken 1 hour before workouts 
  • Week 5: OFF Day (0 mg/day)
  • Week 6: Repeat the above cycle (by increasing daily dosage up by 100mg, if needed, or until desired effects are achieved)

How long should you cycle Tongkat Ali?

  • Dr. Kyle Gillett, MD, a hormone optimization expert recommends cycling Tongkat Ali with 11 months on, and 1 month off.
  • He added that those taking Tongkat Ali and Fadogia Agrestis combo should ideally cycle with 3 weeks on, and 1 week off.

Note on Tongkat Ali cycle:

  • Ideally must be accompanied by regular exercises.
  • OFF and ON cycle enables your hormones to have more time to adjust and gain full effect from Tongkat Ali bioactive ingredients (eg: quassinoids from eurycomanone, alkaloids).

Tongkat Ali cycling of 11 months on and 1 month off is pretty reasonable

A word on Tongkat Ali Dosage

Tongkat Ali is dosage-dependent in order to deliver maximum health gains.

On this note, Tongkat Ali dosage depends highly on its potency (i.e the strength of Tongkat Ali that can be extracted) — and this potency varies from one Tongkat Ali brand to another.

There are many Tongkat Ali brands sold in the US  that recommend 600mg to 1,000mg Tongkat Ali daily.

But do you need to consume 1,000mg of Tongkat Ali daily to achieve the same effects?

The truth is, a higher dose of Tongkat Ali may not be necessary once you understand the relationship between dosage, potency and efficacy.

Is Tongkat Ali dosage dependent on potency?

Tongkat Ali dosage depends highly on the potency of its formulation extract. There is a direct relationship between Tongkat Ali dosage, potency, and efficacy. 


  • Potency is used as a comparative measure of different doses between two Tongkat Ali products/extract that are needed to produce the same pharmacological effect (i.e response).
  • Tongkat Ali efficacy is the ability of a Tongkat Ali product to produce any beneficial effects to health. 

AKARALI Tongkat Ali is formulated to deliver maximum benefits through its dosage-optimized formulation. This is achieved using patented standardized Tongkat Ali extract with 20 years of research and clinical tests.

At 200mg per capsule, this Tongkat Ali supplement is clinically tested to work well on both men and women.

In short, if you are consuming a potent Tongkat Ali product, you can consume a lower dosage (eg: 200mg daily) to produce a similar, if not, higher effect (response) to achieve your health goals.

In comparison, a less potent Tongkat Ali product requires a higher dosage to deliver the required effect. 

Consuming a higher Tongkat Ali dosage from a less potent Tongkat Ali may cause nausea, below-average benefits, and possibly unknown side effects.

The relationship between dosage, potency and efficacy on various Tongkat Ali products are shown below.


  • The strongest Tongkat Ali with the highest potency and efficacy can be found from the best-handpicked roots with cutting-edge standardized extraction technology.
  • Standardized Tongkat Ali extract ensures that your daily Tongkat Ali dosage requirements are met, due to the bioactive consistency that your body requires. 
  • Avoid non-standard Tongkat Ali extract that pushes you to consume higher dosage (i.e more than your body requires)

The truth is, you may not gain more by consuming a higher dosage of Tongkat Ali with lower potency.

We shall share the optimal Tongkat Ali dosage used in various applications to achieve your health goals based on various research and scientific evidence.

Whilst some reported that a 200 mg daily dosage of Tongkat Ali is sufficient to cause a better erection — due to the release of more free testosterone, this depends largely on the level of androgen or testosterone in your body before consuming Tongkat Ali.

Tongkat is dosage and age-dependent. If you are above 65 and diagnosed with low testosterone or androgen deficiencies, you may need a higher dosage between 200mg to 400mg daily between 6 to 12 weeks to notice any improvements.

Andrew Huberman's Tongkat Ali Dosage

It was widely reported that Dr. Andrew Huberman from Stanford University mentioned a significant testosterone increase when taking Tongkat Ali. 

Andrew Huberman’s dosage of  400mg Tongkat Ali was widely referenced as the optimal daily dosage for those seeking a significant testosterone boost.

Anytime I’ve taken more than 400mg per day, I don’t feel good.

However, consuming a higher dosage of Tongkat Ali may not translate to better results.

In his latest video, Dr. Andrew Huberman reported that he was «not feeling good» after taking more than 400mg of Tongkat Ali per day.

Whilst the lethal dosage limit of Tongkat Ali is 30,000mg per day, the maximum recommended dosage of Tongkat Ali for human consumption is believed to be 1,000mg per day.


Higher dosage:

Can I take 1000 mg Tongkat Ali?

It is not recommended to take 1,000mg of Tongkat Ali daily unless there is a reason to do so. For instance, to achieve specific health goals if you are involved in professional bodybuilding or sports.

Most Tongkat Ali studies related to body transformation, and competitive sports are based on 400mg daily consumption of Tongkat Ali over a period of 4 to 24 weeks.

Should I consume more than 1000 mg of Tongkat Ali?

It is not recommended to consume more than 1,000mg of Tongkat Ali daily despite many Tongkat Ali products out there prescribing a higher dosage of 1,000mg or 1,500mg.

In fact, please be wary of such recommendations as it could mean the Tongkat Ali extract has lower potency or low level of bioactive ingredients as a result of low-quality extraction processes.

Please note that Tongkat Ali is not a medicinal drug and a higher dosage from a less potent Tongkat Ali may not translate to higher gains or better health benefits.

For instance, 200mg of a potent Tongkat Ali contains a higher amount of bioactive ingredients compared to a 1,000mg of Tongkat Ali with a low concentrated extract.

Hot-water freeze-dried standardized extract offers higher potency. It means you need between 200mg — 400mg daily dose of Tongkat Ali to deliver optimal gains based on your health goals.

Side effects: High dosage

What happens if you consume more than 1,000mg of Tongkat Ali?

You may experience mild insomnia, higher anxiety, irritability or jittery or even nausea if you consume more than 1,000 mg of Tongkat Ali or higher dose. Some have a higher tolerance to alkaloids and a higher dose of Tongkat Ali will not yield any side effects.

If you have mild or undiagnosed insomnia, or difficulties sleeping, consuming 1000mg or more will worsen the conditions or symptoms associated with a sleeping disorder.

It is recommended to stop consuming Tongkat Ali immediately, or lower your dose to 100mg to 200mg daily should you experience any of the symptoms or side effects from higher doses of Tongkat Ali.

Maximum Toxicity Limit

What is the maximum toxicity limit for Tongkat Ali?

The maximum Tongkat Ali dosage in a single serving on an adult human (100kg) is 30,000mg, guided by the Lethal Dose 50 (LD50)* measurement used in pharmacology and toxicity studies.

An acute toxicity study found that the oral Lethal Dose 50 (LD50) of an ethanol-based Tongkat Ali extract on animals is between 1500-2000 mg/kg, while the oral LD50 of the water-based Tongkat Ali extract is higher than 3000 mg/kg.

Consuming more than 30,000mg of Tongkat Ali in a single dose can be highly toxic to humans and may cause death. As a safety precaution, do not consume more than 1,000mg of Tongkat Ali daily.

Is Tongkat Ali more lethal than caffeine?

In comparison, caffeine has lower LD50, making it more lethal when consumed in smaller quantities / doses.

The LD50 of caffeine in rats is 192 – 367 mg / kg, the fatal dose in humans is estimated to be 150–200 mg/kg (2.2 lb) of body mass, which equates to 75–100 cups of coffee for a 70 kg (150 lb) adult.

This concludes, at higher doses, caffeine can be more lethal than Tongkat Ali and may cause death.

*Note :

  • LD50 stands for Lethal Dose 50%, or median lethal dose, measured by most toxicity studies.
  • LD50 is the amount of a chemical required to cause death in 50% of the animals or humans in the group it is tested on.
  • The LD50 is expressed in milligrams per kilogram (mg / kg) of body weight.
  • The figures are measured when the chemical is given orally, when it is applied to the skin, or when it is injected into the animal. The results of these tests can then be converted into figures for humans based on average adult weight.


Regardless of the dosage, Tongkat Ali is not recommended and never to be consumed if you fall into any of the following categories:

  • Children below 18 years of age
  • Pregnant or breastfeeding mothers
  • Chronic Heart Disease
  • Diagnosed or undiagnosed cancer
  • Positive COVID-19 with Category 4 or 5
  • Chronic insomnia or diagnosed with any form of mental health disorder
  • Mild to chronic allergies to alkaloids, quassinoids, glycosaponin, or caffeine
  • If you have undergone major surgery or an organ transplant in the last 365 days
