Does EROJAN actually work? Six botanicals, ingredient research, lab tests and who it suits (New Zealand 2026)
Reviewed by Health Advisor Team
Short answer: EROJAN suits adult men who run out of energy by mid-afternoon and whose stamina and drive aren't what they used to be. It is a Health Functional Food: Tongkat Ali leads, with Butea superba, Epimedium, Tribulus terrestris, maca and Cuscuta chinensis, six botanicals that work together (1+1 > 2) on the two roots of a man's energy, testosterone and blood flow. The National Poison Centre at Universiti Sains New Zealand screened it for 26 undeclared drugs and found none. It is not a medicine and results vary, so take 2 capsules after meals every day for 8–12 weeks, and use the 30-day money-back guarantee to judge for yourself.
What are the key points?
- What it is: a Health Functional Food for adult men. 60 vegetable capsules a bottle, 2 a day, so one bottle lasts 30 days.
- How it works: six botanicals share the work on two roots (testosterone and blood flow), plus stress and recovery.
- Doses disclosed: per 2 capsules, Tongkat Ali 140mg; Butea superba, Epimedium, Tribulus and maca 120mg each; Cuscuta 60mg.
- What data there is: independent lab results (drug screen, heavy metals, microbes, preservatives, porcine content) and research on each ingredient. Sources are listed below.
- Who it suits: men with long hours, late nights and constant stress, who feel their stamina and drive have dropped since their 30s.
- Who it doesn't suit: children and women. If you have a heart condition, high blood pressure or another medical condition, or take blood-pressure tablets, heart nitrates, prescription sexual-function medicine or other medication, ask your doctor first.
Why don't coffee, catch-up sleep or a single herb last?
Coffee and energy drinks borrow today's energy. Tomorrow you borrow again. A weekend lie-in covers two days, not five days of wear.
Plenty of men have also tried Tongkat Ali on its own and felt a little something, or couldn't tell. Usually it's one herb covering one root, with blood flow left out, or a dose that's too low or not disclosed at all.
There's one more thing most men don't know: only about 2–4% of your testosterone is free for the body to use. Most of the rest is held by a protein called SHBG, which rises with age. EROJAN's idea is to look after both roots together instead of chasing one symptom.
How does the formula match your problem?
| Ingredient | Per 2 capsules | What it does | What you notice |
|---|---|---|---|
| Tongkat Ali (Eurycoma longifolia) | 140mg | The lead. In research it helps free up locked testosterone and lower the stress hormone | Energy, vitality, steadier under stress |
| Butea superba | 120mg | A traditional Thai men's tonic that helps blood vessels relax so blood flows freely | Steadier stamina, less tiredness |
| Epimedium | 120mg | Contains icariin, which works on the nitric-oxide blood-flow pathway | Less of the mid-afternoon slump |
| Tribulus terrestris | 120mg | Saponins that help your vessels release nitric oxide | Circulation and drive |
| Maca (Lepidium meyenii) | 120mg | An Andean root that supports desire and energy by a non-hormonal route | Something left for the last set |
| Cuscuta chinensis | 60mg | A classic tonic herb; antioxidant protection for the cells that make testosterone | Recover a little faster |
All six go into a vegetable capsule. No mixing, no measuring. The label lists the full composition.
How should you read the ingredient research?
EROJAN as a finished product has not published human efficacy trials. What follows is research on single ingredients; doses and study groups may differ from EROJAN, and the results don't mean you will get the same:
- Tongkat Ali: stressed adults taking it for 4 weeks had 37% higher testosterone and 16% lower cortisol, the stress hormone (Talbott 2013, J Int Soc Sports Nutr).
- Butea superba: in a double-blind trial, about 82% of the men reported better sexual function (Cherdshewasart 2003, Asian J Androl).
- Tribulus terrestris: a 12-week controlled trial in 180 men showed clear improvement in sexual function and satisfaction scores (Kamenov 2017, Maturitas).
- Maca: in a controlled trial, men reported a clear lift in sexual desire (Gonzales 2002, Andrologia).
This research explains why these six were chosen. It is not a promise of what EROJAN will do for you. Results vary from person to person.
How should you read the lab tests?
What the product page shows are safety tests done before it reaches you (results from the certificates of analysis issued by each laboratory, Wellous data):
- Undeclared drug screen: 26 drugs, none detected (Toxicology Laboratory, National Poison Centre, Universiti Sains New Zealand, GC-MS)
- Heavy metals: arsenic, cadmium, lead and mercury not detected (Bio Synergy Laboratories)
- Harmful microbes: no microbial, yeast or mould growth; no E. coli, S. aureus or Salmonella (Bio Synergy Laboratories)
- Preservatives: boric acid, benzoic acid, sorbic acid and sulphur dioxide not detected (MY CO2)
- Porcine content: no porcine gelatin or porcine meat in the capsule or the powder (Halvec Laboratories, a JAKIM panel laboratory)
- Certification: GMP certified, Halal certified
"Undeclared drugs" are ingredients that aren't on the label and can't be seen from the pack. Only a lab can find them. Zero out of 26 is the most important line in the report.
How do you tell if it suits you?
- Check the signs: tired by mid-afternoon, long hours and late nights, stress that never switches off, stamina and drive that have dropped. The more you tick, the more it's worth trying.
- Take 2 capsules after meals, every day: for example one after breakfast and one after dinner. Taking it now and then makes it hard to judge. Don't take more than the label dose.
- Track three things: how you sleep, how alert you feel in the day, and your stamina at work and in training. Note them once a week.
- Give it time: many men notice something in weeks 2–4 and the fullest change by weeks 8–12, which is why we recommend 3 bottles (90 days).
- Use the guarantee: don't feel a genuine difference within 30 days? Message your advisor and get your money back in full.
Frequently asked questions
What is EROJAN for?
Energy, stamina and vitality for men. EROJAN is a Health Functional Food, and the label describes it as traditionally used for men's health and energy. Tongkat Ali leads six botanicals, and you take two capsules a day after meals.
Why six botanicals instead of Tongkat Ali alone?
Because a man's energy has two roots: testosterone and blood flow. Tongkat Ali, Cuscuta and maca look after the testosterone side; Tribulus, Epimedium and Butea superba look after blood flow from three angles. They work together, 1+1 > 2, so you don't have to mix your own.
I've tried men's supplements and felt nothing. Why is this different?
Plenty of men have, and it isn't your fault. Usually it's one herb at a low dose, or a blend that won't tell you the amounts. EROJAN names all six botanicals and how many mg of each you get, and covers both roots.
Is EROJAN a medicine?
No. It is a Health Functional Food, not a medicine, is not for treating any disease, and does not take the place of any medicine your doctor gives you.
How long before I feel something?
It differs from man to man. Many sleep better and feel more alert in weeks 2–4, have more stamina at work and in training in weeks 4–8, and feel drive, stamina and confidence come back by weeks 8–12. Read more in how long EROJAN takes to work.
