Does Tongkat Ali Raise Testosterone in Men? What the Trials Found
In a systematic review, tongkat ali raised total testosterone, mainly in men who started with low levels. The trials used 100 to 600 mg a day. A separate 4-week trial found lower cortisol at 200 mg. IronPulseX lists tongkat ali, but the amount per gummy is not published.

Key facts: what do we know about tongkat ali?
- Tongkat ali is the root of Eurycoma longifolia. It is one of the six named plants in IronPulseX.
- A systematic review and meta-analysis found it improved serum total testosterone in men (Leisegang et al., 2022).
- The rise showed mostly in men who started with low levels, so men with normal levels may see less.
- The trials in that review gave 100 to 600 mg a day.
- A 4-week trial in 63 moderately stressed adults used 200 mg a day. Cortisol fell and some mood scores improved (Talbott et al., 2013).
- A higher blood number is not the same as a change a man can feel.
- The amount of tongkat ali in an IronPulseX gummy is not published.
Tongkat ali is one of six
IronPulseX holds 30 gummies a bottle, and the amount of each plant is not published, so follow the label.

What is tongkat ali, and why is it in men's gummies?
Tongkat ali is a root. Its Latin name is Eurycoma longifolia. It shows up in many men's formulas, often next to words like drive, stamina and vitality.
The reason is simple. It has more human trial data on a male hormone than most plants in this market. That makes it a natural headline ingredient, and it sits first on the IronPulseX list.
Being first on a list does not tell you how much is in the product. The IronPulseX label names the plant and prints no amount. Keep that gap in mind for everything that follows.
What did the big review of tongkat ali trials find?
A 2022 systematic review and meta-analysis pooled trials of the root in men. It reported that serum total testosterone improved (Leisegang et al., 2022). A meta-analysis combines several trials, so it gives a firmer view than one small study.
The detail matters, though. The gain appeared mainly in men whose levels were low at the start. For a man whose levels are already normal, there may be less room to rise.
| Question | What the review found | What it means for you |
|---|---|---|
| Did testosterone rise? | Yes, in pooled trials | A real signal, not a guarantee |
| Who gained most? | Men who started low | Normal levels may see little change |
| What doses were used? | 100 to 600 mg a day | A wide range, set by each trial |
| Was the finished gummy tested? | No | IronPulseX itself has no published trial |
Does tongkat ali also affect stress and mood?
One small trial looked at that. It gave 200 mg a day for four weeks to 63 moderately stressed adults. Cortisol, a stress hormone, fell, and some mood scores improved (Talbott et al., 2013).
That study did not measure testosterone as its main aim. It matters because it shows a second possible route. If stress eases, daily energy and interest may feel better even if no hormone moves.
Still, one four-week trial is small. Treat it as a pointer. It is not a promise about a gummy with unknown amounts.
Does a higher testosterone number mean you will feel different?
Not always. Think of a blood result as one reading on a dial. Drive, mood and energy depend on many other dials: sleep, stress, weight, health, medicines and relationships.
A trial on another IronPulseX plant shows the gap. Ashwagandha raised testosterone against placebo in 43 men, yet fatigue, vigor and sexual wellbeing did not beat placebo (Lopresti et al., 2019). We make no claim that tongkat ali behaves the same, but the lesson travels.
How does the research dose compare with an IronPulseX gummy?
The trials used 100 to 600 mg of the root a day. That is a lot of plant for a chewable that must also hold a base, a sweetener and five other actives.
| Item | In the research | In IronPulseX |
|---|---|---|
| Daily amount | 100 to 600 mg | Not published |
| Extract type | Set by each trial | Not published |
| Gummies a day | Not applicable | Follow the label; number not printed in our materials |
| Trial of the finished product | Not applicable | None published |
None of this proves the gummy is under-dosed. It shows that nobody can say. A buyer who wants to match a study dose has no figure to match it to.
Is tongkat ali safe for men?
The trials we cite were short and small, and our sources give no side-effect figure for the root. Missing data is not the same as proof of safety.
IronPulseX also holds ashwagandha, which has rare liver and thyroid reports (NIH ODS, 2025). If you use nitrate, blood-pressure, thyroid or sedative medicines, or blood thinners, talk to your doctor before use.
If low drive or erection problems are why you are reading, see a doctor first. New erection problems can be an early sign of heart disease, and a supplement cannot rule that out. A doctor can also test your testosterone level.
How can you test a tongkat ali product fairly at home?
Write a baseline
Before day one, score energy, stress and drive from 1 to 5. Note your usual sleep.
Take it as the label says
Do not add extra gummies to speed things up.
Change nothing else
A new diet or training plan in the same weeks will blur the result.
Log once a week
Compare each week with your baseline, not with yesterday.
Decide before day 60
Make the call around day 50 so you can still use the refund window.
Frequently asked questions
Does tongkat ali raise testosterone?
A systematic review of trials found it improved total testosterone in men, mainly those who started low. The doses were 100 to 600 mg a day.
How much tongkat ali is in IronPulseX?
The amount is not published. IronPulseX names tongkat ali as one of six plants but prints no milligrams.
Does tongkat ali lower cortisol?
In a 4-week trial of 63 stressed adults, 200 mg a day lowered cortisol and improved some mood scores.
Will tongkat ali improve sex drive?
The review measured a hormone, not drive. A higher blood level does not always mean a man feels a change.
Is tongkat ali safe?
Our sources show short, small trials and no side-effect figure. Ask your doctor first if you take medicine or have a health condition.
Does IronPulseX claim to raise testosterone?
No. Its four label lines cover blood flow, drive and stamina, everyday stress and a daily gummy. None names testosterone.
Our view
Tongkat ali is the best-supported plant in the IronPulseX list when the question is a hormone number. That is a real point in the formula's favor.
But the support belongs to the root at set doses, in men who often started low. IronPulseX prints no dose, and no trial has tested the gummy.
So we call it a reasonable ingredient with an unknown amount. If you try it, keep modest hopes, log your weeks and ask a doctor about a blood test if hormones are your real worry.
