Nu-Prep Lelaki Tongkat Ali Review – Will it increase testosterone?

Nu-Prep Lelaki Tongkat Ali Review – Will it increase testosterone?

My Biotropics Nu-Prep Lelaki Tongkat Ali Testosterone Booster Review First Look

Often we come across natural testosterone boosters which are not marketed to the guys looking to make huge gains in the gym.

Sometimes guys just want to feel the health benefits that a higher level of testosterone can bring, particularly if they are older.

If so, bottles of supplements with large imagery of hulking men or animals will not be their first port of call.

To reach out to these guys there’s often a healthcare image that is used.

A product that looks like it could be sold in a healthcare store may seem attractive.

That’s what this looks like.

As men age, they often make less testosterone – []

Can Lelaki hit the mark? Let’s look at their background…

Who Are Biotropics?

Established in 2007, Biotropics were set up to utilise the vast natural resources that have health benefits in Malaysia.

The Biotropics mission is to combine traditional remedies with modern science to create developing herbal medicines and botanical drugs.

What Are the claims from Lelaki by Biotropics?

  • Enhance health
  • Improve vitality
  • Reduce fatigue
  • Strengthen the body
  • Improve blood circulation

Initial Summary


Transparent dose

No proven ingredient

Low dose

Ingredients: The Science

So, let’s list through each ingredient and look at the associated studies:

– Eurycoma Longifolia (Longjack)

There is evidence that longjack when dosed at 200mg daily does increase testosterone levels in human subjects.

[Bhat R, Karim AA. Tongkat Ali (Eurycoma longifolia Jack): a review on its ethnobotany and pharmacological importance. Fitoterapia. (2010)]

How To Take Nu-Prep Lelaki

We are to take two capsules per day.

It is better to spread the dose out over the course of the day.

This ensures our body has a constant supply of nutrients to work with.

This will prevent peaks and troughs.

If you supply your body with lots of the same nutrients at once it will pass what is not required.

Thus, a higher chance of waste and less benefits.

It is better to have a continued trickle effect.

This results in a daily dose of 200mg of Tongkat Ali

This low dose is much less than what you would find in the best natural testosterone boosters which will consist of 3000mg or more when combined with other ingredients.




Unfortunately there is little to shout about.

According to the studies, or at least some studies that may be sponsored by Biotropics, Tongkat Ali may increase the quality and concentration of sperm.

This is only for men who are suffering from infertility though.


The science and the manufacturer claims do not stack up.

This supplement from Biotropics claims that it will:

  • Increase testosterone
  • Increase interest in sex
  • Increase strength
  • Destroy fatigue

However, according to the available studies and science this fails on every point.

At best it may increase sperm in men who are infertile.

However, according to the World Health Organisation only 12% of the global male population are infertile.

WHO even admit that figure is a generous estimate an the likelihood is that the figure is far lower.

Unwanted Lelaki Side Effects

It seems that there are very few documented unwanted side effects from Nu-Prep Lelaki.

Due to a lack of reliable information and studies use with caution if you are pregnant and breastfeeding.

What Improvements Could Be Made to Lelaki?

There are some major improvements to be made.

By containing just one ingredient I feel this is a lost opportunity.

If it was to include a number of proven ingredients that are known to increase testosterone this would offer a greater degree of performance.

Look at the ingredients listed below which would be of benefit:

  • B12
  • Vit. C
  • B6
  • Oyster
  • D3
  • Zinc
  • Ginseng
  • Creatine
  • Fenugreek
  • K2
  • Magnesium
  • D-Aspartic Acid

Some of these proven ingredients are included in the best testosterone boosters such as TestoFuel.

My Nu-Prep Lelaki Tongkat Ali Testosterone Booster Review Conclusion

It contains just one ingredient.

This ingredient should be complimented with eight or more clinically proven ingredients that are able to help elevate natural testosterone levels.

Then you would have a well-rounded product to help maximize your potential.

Thus, you should check out the better options, here.

Biotropics Nu-Prep Lelaki Rivals

Let’s see what other best rated natural testosterone booster supplements are pitched against Lelaki.

Prime Male

It is hard not to make a good case for Prime Male because it is so effective due to its large number of proven and distinctly well regarded ingredient profile.

Prime Male has been proven to help increase natural testosterone levels and is backed by some great figures from the world of sport and film.

Developed with the older man in mind, it is still useful for all ages, and women.


  • Contains twelve clinically proven ingredients to help stimulate testosterone
  • Contains anti-inflammatory ingredients to help prevent chronic disease
  • Helps control stress levels


  • The dose of D-Aspartic Acid would benefit from being higher
  • It misses out on Fenugreek


Along with TestoFuel, TestRX contains some higher doses of the ever important yet often overlooked Vitamin D3 and D-Aspartic Acid.

TestRX has also been on the scene for a good number of years, this longevity is a reflection of the powerful ingredients included.

It’s only reason for a lower score is the lower number of ingredients included.



  • High doses of D3 and D-Aspartic Acid
  • Includes Fenugreek which stimulates test levels and cuts fat
  • Well established product standing the test of time


  • Fewer number of total ingredients included per dose
  • Omits a couple important ingredients such as Boron


How can we not mention a number of rival natural testosterone boosters without including the No.1 TestoFuel?

TestoFuel has long been the highest rated test booster due to the collection of proven ingredients with the correct dosage to have the best effects.

This is has been my first choice for over three years now and I couldn’t feel better without it.

See what you could be missing out on.


  • Contains nine scientifically proven ingredients to help stimulate testosterone
  • Strong doses of Vitamin D3 and D-Aspartic Acid
  • Fenugreek has dual benefits


  • Only available by direct online order from the manufacturer
  • I wish it contained Boron
