LJ100 vs Tongkat Ali - Details Explained

Tongkat Ali is a supplement derived from the root of the Eurycoma longifolia plant.

It can be found in both standardized and non-standardized extracts.

LJ100 is a standardized extract of Tongkat Ali that has also been patented.

One issue when comparing standardized to non-standardized extracts is that we need a common unit of comparison.

With Tongkat Ali the active ingredients of the plant are still not 100% clear.

There’s some suggestion that Eurycomanone may be one of the active ingredients.

Unfortunately not all Tongkat supplements quote their concentration of it, so we can’t use that to compare.

For example, LJ100 quotes:

22% Eurypeptides
40% Glyco Saponins

However, those are different to Eurycomanone.

Dosing LJ100

It’s not easy to compare the strength of LJ100 to regular Tongkat Ali as we do not have a common unit of comparison.

However, what we can do is look at the doses of LJ100 used in studies.

LJ100 is known as Physta in Malaysia, and has been used in 9 studies that a meta-review covers¹.

These studies use between 100 mg and 600 mg. See Table 1 of the paper for a nice summary of how the different doses affected testosterone levels vs placebo.

In terms of frequency of doses being studied, they were:

100 mg x 1
200 mg x 3
300 mg x 2
400 mg x 1
600 mg x 2

Then one paper looked at a dose of 1.7 mg per kg. So for a 70 kg (154 lb) human that would be ~120 mg.

This gives us some lower (100 mg) and upper (600 mg) bounds for doses, with 200 mg per day being the most commonly tested.

Manufacturing & Patent Info

LJ100 has been patented (see patent #7,132,117), and is made by a company called HP Ingredients who are based in Florida.

They source the plant itself from Malaysia, and it is processed in a Malaysian GMP factory. Once the product is completed, it is provided wholesale to supplement companies to use in their branded products.
