LJ100’s Ingredient

Nutrex Tested Ingredients

Nutrex Tested not only ha a huge 200mg dose of LJ100, but adds boron for free testosterone support too!

Nutrex Tested contains two ingredients – 200mg LJ100 and 100mg Boron Citrate (yielding about 5mg boron), making for what we believe to be the strongest and best Tongkat Ali supplement on the market.

It’s an herb that belongs to the Simaroubaceae Eurycoma family of plants and has traditionally been used for its aphrodisiac and pro-fertility effects[1-3] – but there’s a growing amount of research that it’s capable of even more – great news for natural athletes.

What’s Special about LJ100

Nutrex pulls out all the stops with their latest product by using the patented LJ100 Tongkat Ali extract, and a serious amount of it. This extract is synthesized using a special extraction process that involves high pressure, high temperature, reverse-osmosis water extraction. After that, the extract is put through an ultrafiltration process and finally freeze-dried yielding a product of superior quality as compared to all other Longjack extracts that are currently used.

LJ100Ⓡ is a 100:1 extract which means it packs 100x more active compounds than found in a typical whole plant extract. So, if this is so great, why don’t more products use LJ100?

  • This patented version costs about 20x more than a crude extract
  • There are plenty of lower quality extracts that claim to be of LJ100’s quality but have turned out to be fakes.
  • LJ100Ⓡ is the ONLY version of Longjack extract that has human studies to validate its claims

LJ100’s Benefits

Ok, so we’ve got some kind of super-fancy, high-quality extract of a mystical herb…what can it DO for me?! We’re glad you asked! LJ100 has been proven to do the following:

  • Muscle Maker

    LJ100 has proven itself as a very effective ergogenic aid in terms of workout performance and overall body composition.

    1. Body Composition Improvements

      In the first study, 7 men received 100mg/day of LJ100 and 7 received a placebo. Each group was subject to an 8 week resistance training program. At the end of the study, the group receiving LJ100 showed marked improvements in lean mass gains, body fat levels, overall strength (1RM) and arm circumference over the placebo group.[4]

    2. Hormonal Balance

      Nutrex Vitadapt

      Nutrex Vitadapt is a multivitamin with 300mg KSM-66 Ashwagandha, which may also help in the testosterone department!

      The second study involved 30 male subjects engaged in a 24-hour mountain bike event. 15 of the men received 100mg dose of LJ100, while the other 15 men did not. At the end of the trial, the group receiving LJ100 had decreased levels of cortisol and higher levels of testosterone than the placebo group.[5]

    So, not only does Tested help you pack on some nice muscle gains and trim body fat, but it also promotes an anabolic environment and prevents catabolism from setting in!

    This leads us to wonder if LJ100 is on the verge of being a next-generation muscle building supplement, although we’d love more human-researched studies to get published!

  • Tension Tamer

    In a study conducted on 63 individuals (32 men and 31 women), supplementing with 200mg/day of Tongkat Ali significantly reduced cortisol levels and showed improvements in tension, anger, and confusion.[6] So, not only does LJ100 help you pack on pounds of muscle, it will also help you mellow out so you can enjoy your downtime.

  • Sexual Health Booster

    Not only does LJ100 help you put on muscle and lower your stress levels, it will keep you going long and strong in the bedroom! A number of trials involving LJ100 have resulted in increased semen volume, erectile strength, stamina, and libido levels.[5,7]

LJ100 is often marketed as an ingredient that “maintains testosterone levels”, but the jury is still out as to whether or not this potent of an extract (and this high of a dose) can have a hormonal impact on healthy men.


As a dietary supplement, take two to three capsules daily. Cycle LJ100 by taking it for five day on, followed by two days off, then repeating the process.

Stacking LJ100?

This is a truly versatile product – you can use it standalone, stack it with other test-boosting supplements (or even the Vitadapt multivitamin, which has KSM-66 shown to the right), or use it during a PCT cycle!


It certainly seems that Nutrex has brought another worthwhile supplement to the market, and with more research to come expounding on LJ100’s numerous benefits.

There are a ton of reasons to consider using this, whether you’re a natural supplement user looking for that extra kick, or a more “aggressive” hormonal customer who wants to stack it into a PCT cycle.

LJ100Ⓡ is a promising supplement on many different levels and can benefit people of all sorts, from athletes to the elderly to those guys who just want a “power-up” in the bedroom. Be on the lookout for LJ100Ⓡ in Nutrex and make sure you sign up for the deal alerts below!
