Why standardization matters
The ingredient name tells you what plant was used—not the strength or consistency of the extract.

Active 01
200 mg daily • Standardized to 1.5% eurycomanone
Tongkat Ali has been studied for its role in supporting healthy testosterone levels and the body’s response to stress. LJBOOST™ is standardized to 1.5% eurycomanone—giving you a defined extract instead of an unspecified root powder.
What the research suggests
Human research on standardized Tongkat Ali extracts suggests potential support for testosterone—particularly in men with lower starting levels—and stress-related outcomes. Studies used different extracts, populations and durations, so individual results may vary.
Research · Tongkat Ali
What researchers found
Taken together, the trials showed Tongkat Ali increased total testosterone, with the clearest effect in men who started with low levels.
Limitations
The pooled trials used different extracts, doses and participant groups, and the authors flagged possible publication bias.
What researchers found
Compared with placebo, the Tongkat Ali group showed lower salivary cortisol, higher salivary testosterone and less tension, anger and confusion.
Limitations
Funded by the extract's manufacturer; a short study that included women and used Physta™, not LJBOOST™.
What researchers found
Tongkat Ali alone did not significantly change strength, power or the testosterone:epitestosterone ratio; the clearest gains came from the training itself.
Limitations
Small groups of about 10 men each over 8 weeks; university-run with no manufacturer funding disclosed.
What researchers found
Total and free testosterone and handgrip strength rose in both men and women.
Limitations
No placebo group and a small sample, at twice the NEXEDGE dose.
What researchers found
The share of men with testosterone in the normal range rose from 35.5% to 90.8%, and ageing-male symptom scores improved.
Limitations
There was no placebo group, so some of the change may not be due to the extract.
What researchers found
Eurycomanone supported testosterone production by acting on enzymes involved in making and converting testosterone.
Limitations
Cell and animal findings explain a possible mechanism but do not show results in people.
Active 02
100 mg daily • Standardized Extract
Black Ginger has been studied for its potential role in physical performance and energy metabolism. MANOVA™ support how the body uses energy without caffeine or stimulants.
What the research suggests
Human studies of standardized Black Ginger extracts have reported improvements in selected measures of physical fitness, although results are mixed and the clinical evidence remains limited.
Research · Black Ginger
What researchers found
Black Ginger increased handgrip strength in the trials that measured it, and no adverse events were reported even at 1.35 g a day.
Limitations
The authors called the evidence inconclusive: the studies were small, and the grip-strength result rests on only two trials.
What researchers found
Right-hand grip strength improved at weeks 4, 8 and 12, and left-hand grip strength at week 8, compared with placebo.
Limitations
Sprint, leg strength, flexibility and cardio fitness did not differ from placebo, and the extract was not MANOVA™.
What researchers found
Whole-body energy expenditure rose within an hour of taking the extract, but not after placebo.
Limitations
It measured a single dose over a few hours, not daily use or physical performance.
What researchers found
Mice swam longer and had stronger grip, with more mitochondria and stored glycogen in their muscles.
Limitations
Results in mice help guide research but do not show the same effect in people.
What researchers found
Methoxyflavones from Black Ginger moderately inhibited PDE5, an enzyme involved in blood-flow signalling.
Limitations
Enzyme tests in the lab show a possible mechanism, not an effect in people.
Why these two
NEXEDGE combines two standardized extracts with two distinct roles.
Support the foundation
Support daily performance
Research currently supports the ingredients individually. The combined NEXEDGE formula has not been evaluated in a clinical trial.
From source to standard
Most supplement brands begin with a finished ingredient. We begin with the botanical—developing the extract, defining its specifications and deciding exactly how it belongs in the formula.
01
The correct botanical species and plant part.
02
A controlled process designed to capture the intended compounds.
03
Each extract is made to defined specifications for consistency.
04
Precisely dosed at 200 mg LJBOOST™ and 100 mg MANOVA™.
Our evidence standard
Not every study carries the same weight. We identify the extract, dose, duration and participants—then separate the evidence clearly.

Research library
Every study is summarized in plain English, labelled by evidence type and linked to the original paper.
10 studies shown
Clinical trials collectively suggest that Tongkat Ali may support total testosterone, with clearer findings among men who started with lower levels.
Context: Different extracts, doses and participant groups were included.
In 63 moderately stressed adults, 200 mg daily for four weeks was associated with changes in stress-hormone balance and selected mood measures.
Context: This study used Physta™, not LJBOOST™, included both men and women, and was funded by the extract's manufacturer.
In 60 male soccer players, 180 mg daily for 12 weeks improved selected grip-strength measures.
Context: Several other performance measures did not significantly differ from placebo. The extract studied was not MANOVA™.
Across seven small clinical studies, Black Ginger improved handgrip strength, and no adverse events were reported at doses up to 1.35 g a day.
Context: The authors judged the evidence inconclusive; grip strength was measured in only two trials.
In 40 young men over eight weeks, 200 mg daily of Tongkat Ali alone did not significantly change strength, power or the testosterone:epitestosterone ratio.
Context: A university-run study with no manufacturer funding disclosed—an important check on more positive, industry-funded results.
In 25 active adults aged 57–72, 400 mg daily for five weeks increased total and free testosterone and handgrip strength.
Context: No placebo group; twice the NEXEDGE dose.
A single dose of Black Ginger extract increased whole-body energy expenditure in healthy men within an hour.
Context: Acute, single-dose study; it did not measure daily use or performance.
Eurycomanone, the marker compound in Tongkat Ali, supported testosterone production by acting on enzymes involved in steroid production.
Context: Cell and rat models; not a human result.
Methoxyflavones from Black Ginger moderately inhibited PDE5, an enzyme involved in blood-flow signalling.
Context: Enzyme assays only.
Mice given Black Ginger extract for four weeks swam longer and had stronger grip, with more muscle mitochondria and glycogen.
Context: Animal findings do not prove results in people.
