Longjack (Eurycoma longifolia) boosts natural testosterone if you source the right kind — LJ100. Here's what you need to know.
Several natural supplement ingredients purportedly boost testosterone. Some work and some don't. But the one with the best track record and the most solid clinical research behind it is Longjack (Tongkat Ali), derived from the Malaysian Eurycoma longifolia root.
LJ100 Longjack was developed and patented by the Government of Malaysia and the Massachusetts Institute of Technology – the same material that's in Biotest's Omega-Man High Absorption Longjack. The patent is titled Bioactive Fraction of Eurycoma Longifolia. It describes a standardized extract that increases testosterone synthesis and production from bioactive fractions of Eurycoma longifolia. The bioactive fractions were later revealed as eurypeptides, glycosaponins, and eurycomanone.
The patent is for increasing testosterone by two actions:
Synthesizing testosterone by blocking its aromatization into estrogen.
Stimulating testosterone production in testicle Leydig cells.
Four recent studies show significant benefits of LJ100:
Supplementation of 200 mg of LJ100 increases serum total testosterone, reduces fatigue, and improves the quality of life in aging men within only 2 weeks.
200mg of LJ100 plus training improved erectile function and increased total testosterone levels in aging men with androgen deficiency.
There were significant benefits of exercise and LJ100 consumption as a non-pharmacological treatment for androgen deficiency.
The raised testosterone following LJ100 supplementations could benefit muscle and strength gain in young adults.
So, why do some Longjack supplements raise testosterone while others don't?
There are three reasons:
They don't contain active Longjack
They're underdosed.
Absorption of Longjack active ingredients varies among individuals.
Omega-Man contains 300mg of LJ100 per softgel/dose, 50% more than standard clinical dosing.
Omega-Man is formulated in a self-emulsifying delivery matrix designed to get all active fractions into the body. The microemulsion is a game-changer for complete absorption.
I used Alpha Male according to the protocol on the bottle for over 6 months. It did not increase my testosterone at all. Testosterone increased total and free by a lot, at a similar price point.
Great article, TC. I had been purchasing Tongkat from Horbaach through Amazon. As I often do, I go directly to the company’s website (maybe it’s cheaper there or at least I pay them directly). Big problem, they’re not selling Tongkat on their own website, but they are on a Horbaach store front. Looks like I’m in the market for another brand! (Also, their ratio is 200:1 FYI) Might try Alpha Male. Thanks for the tips.
Yes. I’m currently using injectable testosterone and anastrozole pills. I encourage anyone using non-prescription testosterone boosters to do before and after testing to make sure you’re getting a bang for your buck. Actual testosterone is giving me felt, observable and measurable results. Unfortunately, the supplement didn’t.
I think I mentioned that tongkat Ali isn’t for anyone with true hypogonadism. Instead, it’s for people who want to increase their natural T levels, to be slightly more than they are, hormonally speaking.
Can you please elaborate on that? I was under the impression that Tongkat cycling was 5 days on and 2 days off? Does the short half-life have an impact on this transition? Any risks associated with such a long-term supplementation?
I also used Alpha Male and experienced no credible results. Every 3 months I get a blood panel and for over 6 months and 2 panels nothing changed! With due respect, I will never use Biotest products.
I used alpha male with observable/felt results (increases in strength, endurance, libido, and decreased DOMS and recovery times). Never measured test on or off it though.
How does this new Omega Male product compare to the discontinued Alpha Male in estimated effect on total and free testosterone (understanding there isn’t a clinical trial comparing them, just looking for a best guess)?
So, it doesn’t really specifically specify a particular time to take the dose, but is it safe to assume on training days you want to dose either before or after training?
