Quick Answer
Tongkat ali usually takes two to 12 weeks to work, depending on what you are measuring. In trials, blood testosterone rose after two weeks at 600mg a day, stress hormones and mood scores shifted at four weeks, and physical functioning and sexual wellbeing scores improved at 12 weeks. Plan on at least four weeks of daily use, and 12 weeks before you judge it. If you are starting a course, our pick is Eternal Elixir Tongkat Ali 2000mg: a 200:1 extract, 90 capsules for $39.99, which is $1.33 a day.
Eternal Elixir makes Tongkat Ali 2000mg, so read this as our pick with the working shown. Competitor prices were read from each live listing on 26 September 2026.
If you have just started tongkat ali (Eurycoma longifolia), the first question is usually how long it takes to work. The answer depends on the goal. Changes in blood hormones have been measured within two weeks, while the changes people actually notice, in stress, drive, training and sexual wellbeing, were measured after four weeks to six months.
This guide sets out the timeline the human trials support, what they used, how our serve compares, and how to judge your own course. For the full picture on tongkat ali, start with our tongkat ali Australia guide.
How long does tongkat ali take to work? The timeline from the trials
Each row is a randomised or pilot trial we could verify. Doses are daily amounts of tongkat ali extract.
| When measured | Dose | What changed | Who |
|---|---|---|---|
| 2 weeks | 600mg | Total and free testosterone rose more than on placebo, and so did estradiol | 32 healthy young men (Chan, 2021) |
| 4 weeks | 200mg | Cortisol in saliva 16% lower and testosterone 37% higher than placebo, with lower tension and confusion scores | 63 moderately stressed adults (Talbott, 2013) |
| 5 weeks | 400mg | Total and free testosterone and handgrip strength rose (no placebo group) | 25 active adults aged 57 to 72 (Henkel, 2014) |
| 12 weeks | 300mg | Physical functioning scores improved more than on placebo, and libido scores rose 14% | 109 men aged 30 to 55 (Ismail, 2012) |
| 6 months | 200mg | Sexual function scores and total testosterone improved most when tongkat ali was combined with training | 45 men averaging 47 (Leitão, 2021) |
Read it this way. Blood changes came first. The things you might feel, such as less tension or better drive, were measured from four weeks, and training and sexual wellbeing outcomes took three to six months. These trials didn’t measure same-day effects, so there is no evidence of a quick, stimulant-like kick.
What each trial found
Two weeks: testosterone in young men
In a double-blind, placebo-controlled trial, 32 healthy young men took 600mg a day of tongkat ali extract or a placebo for two weeks. Total testosterone (p = .005) and free testosterone (p = .012) rose more in the tongkat ali group, and estradiol rose too. Luteinising hormone, follicle-stimulating hormone and sex hormone-binding globulin did not change (Chan et al., Andrologia, 2021). Two weeks captured a blood change, and the trial did not ask whether the men felt different.
Four weeks: stress hormones and mood
In a four-week trial, 63 moderately stressed adults (32 men and 31 women) took 200mg a day of a standardised hot-water extract or a placebo. The tongkat ali group had 16% lower cortisol exposure and 37% higher testosterone, measured in saliva. Tension scores fell 11% and confusion scores 15% (Talbott et al., Journal of the International Society of Sports Nutrition, 2013). The extract’s maker funded the study.
Five weeks: older adults and strength
In a five-week pilot study, 13 men and 12 women aged 57 to 72, all physically active, took 400mg of tongkat ali extract a day. Total and free testosterone and handgrip strength rose in both men and women (Henkel et al., Phytotherapy Research, 2014). There was no placebo group, so treat it as a lead rather than proof.
Twelve weeks: wellbeing in men aged 30 to 55
In a 12-week randomised, double-blind trial, 109 men aged 30 to 55 took 300mg a day of a water extract (Physta) or a placebo. The tongkat ali group improved more on the physical functioning part of a standard quality-of-life survey (p = 0.006), scored higher on sexual wellbeing questionnaires, and reported a 14% rise in libido by week 12. Safety measures were comparable to placebo (Ismail et al., Evidence-Based Complementary and Alternative Medicine, 2012).
Six months: tongkat ali plus training
A six-month, double-blind, placebo-controlled trial randomised 45 men averaging 47 years, all with symptoms of age-related androgen decline, to four groups: placebo, 200mg of tongkat ali, training plus placebo, or training plus tongkat ali. Sexual function scores improved in both active groups, and the combination of tongkat ali and training gave the best results and a rise in total testosterone (Leitão et al., Maturitas, 2021). The authors noted the design had no group taking tongkat ali alone, so the two effects can’t be fully separated.
Across studies, a 2022 meta-analysis of five randomised trials found men taking tongkat ali had significantly higher total testosterone than controls (Leisegang et al., Medicina, 2022). We cover the wider research in tongkat ali benefits in Australia.

Testosterone
The fastest measured rise was at two weeks, at 600mg a day in young men. At 200mg to 400mg a day, changes were measured at four to five weeks. If you are tracking this with blood tests, test before you start and again after at least four weeks, at the same time of day.
Stress and mood
The one tongkat ali stress trial measured its results at four weeks, and the extract’s maker funded it. Expect any change to be subtle. If stress is your main goal, our tongkat ali vs ashwagandha comparison explains why ashwagandha has more stress trials.
Libido and sexual wellbeing
The trials that measured these ran for 12 weeks and six months. Give it at least 12 weeks before judging.
Strength and training
The strength data is thin: a five-week pilot with no placebo group, and a six-month trial where training did much of the work. Tongkat ali is not a substitute for a training program. Our testosterone protocol for men over 35 puts it alongside sleep, training and diet.
Our serve compared with the trial doses
The trials above used 200mg to 600mg of extract a day. Our label serve is three capsules, or 2,000mg of a 200:1 extract, taken on an empty stomach. That is well above every trial dose here, and we found no trial that tested a serve that size. A review of tongkat ali safety notes that traditional use is 100mg to 400mg a day and that there is no standard for the purity and strength of extracts, so milligrams don’t convert one for one between products. Follow the label on the product you buy, and ask your doctor or pharmacist if you want to start lower. Our tongkat ali dosage guide goes through the numbers.
What affects how fast you notice anything
- Your starting point. The meta-analysis found the rise held in men who started with low testosterone. Men already in a healthy range may notice less.
- Daily consistency. Every trial above used daily dosing. Skipping days means you are no longer following what was tested.
- Training, sleep and alcohol. In the six-month trial, the best results came from tongkat ali combined with training.
- The extract. The better-described trials used standardised water extracts, and labels vary widely. Check for an extract ratio (such as 200:1) or a stated eurycomanone content.

Add Tongkat Ali 2000mg to cart · $39.99How to judge your own course
Pick one goal and one measure before you start: a blood test for testosterone, a weekly 1 to 10 rating for stress or drive, or your training log for strength. Take the same serve at the same time each day for at least 12 weeks, change nothing else if you can, and compare with your starting point. Three of our bottles cover 12 weeks at the label serve.
Our tongkat ali label says to take it on an empty stomach. No trial has compared morning and evening dosing, and many people take it in the morning. On cycling, such as five days on and two off, we found no trial that tested it. Our tongkat ali protocol guide covers the common approaches.
Some men pair tongkat ali with other herbs. Our Tongkat Ali and Fadogia product is currently out of stock, and our fadogia agrestis dosage guide explains how that pairing is used. For energy rather than hormones, some people add Korean Panax Ginseng 1600mg ($44.99 for 90 capsules). Men over 40 building a wider routine can start with our guide to the best supplements for men over 40, or browse the full Eternal Elixir range.
Safety over the weeks
The 12-week trial above reported safety measures comparable to placebo. A 2024 safety review of tongkat ali says side effects in clinical studies were usually uncommon and minimal, rates it a possible rare cause of liver injury, based on isolated case reports, and lists nausea, stomach discomfort, diarrhoea, headaches and rash as effects reported at usual doses (LiverTox, 2024). Stop and see your doctor if you notice yellowing skin or eyes.
Talk to your doctor first if you take prescription medicine or have a hormone-sensitive condition, and avoid it if you are pregnant or breastfeeding. Tongkat ali raised estradiol as well as testosterone in the two-week trial. Our tongkat ali side effects guide covers more, and our guide to tongkat ali for women covers use by women.
Which tongkat ali to start with
Our pick is Eternal Elixir Tongkat Ali 2000mg. It is a single-ingredient 200:1 extract, 2,000mg per three-capsule serve, 90 capsules to the bottle, at $1.33 a day. For a full 12-week course, three bottles at 15% off bring it to $1.13 a day and clear the $100 free-shipping threshold. Orders ship from Sydney within 24 hours with a 30-day money-back guarantee.
Stated plainly: our serve is above the trial doses, and our label doesn’t give a eurycomanone percentage. If you would rather take a smaller daily amount with a stated eurycomanone content, Evolution Botanicals is the cheapest per day in our table at $0.58.
Tongkat ali timing: frequently asked questions
How fast does tongkat ali increase testosterone?
The fastest measured rise was after two weeks, in young men taking 600mg a day. At 200mg to 400mg a day, rises were measured at four to five weeks. A 2022 meta-analysis of five randomised trials found a significant rise overall.
What happens if I take tongkat ali every day?
Daily use is what the trials tested, for two weeks to six months, and a safety review says side effects in clinical studies were usually uncommon. The same review rates it a possible rare cause of liver injury from isolated case reports. Talk to your doctor first if you take prescription medicine, and follow the label.

How does tongkat ali make you feel?
Not like a stimulant. In the stress trial, people taking 200mg a day for four weeks reported lower tension and confusion scores than those on placebo. Many people notice nothing obvious in the first weeks, which is why a 12-week course with a set measure works better than judging by feel.
What’s the best time to take tongkat ali?
No trial has compared times of day. Our label says to take it on an empty stomach, and many people take it in the morning. Pick one time and keep it the same every day.
What is the best tongkat ali supplement in Australia?
Our pick is Eternal Elixir Tongkat Ali 2000mg: 2,000mg of 200:1 extract per serve, 90 capsules for $39.99, shipped from Sydney. Eternal Elixir makes it, so weigh that. Evolution Botanicals has the lowest cost per day of the products we compared, at $0.58. Our tongkat ali comparison covers more brands.
Should you cycle tongkat ali?
Many people do, often five days on and two off, but we found no trial that tested cycling. The trials used daily dosing for up to six months.
