Tongkat Ali is a supplement that comes for a tree native to Malaysia, Thailand and Indonesia. Its active ingredient is Eurycoma Longifolia and it is also known by the names Longjack, Malaysian Ginseng, Tongkat ali, Longjax, Pasak Bumi, Cay Ba Binh, Langir Siam, and Tung Sawa. It has been used around Asia for many years to increase sexual desire, libido, and sexual performance in men, as well as to treat erectile dysfunction. Erectile dysfunction is when a man is unable to perform sexually.
There is not a lot of scientific support for the effectiveness of the tongkat ali root, but there are some preliminary lab studies that show that it might have some effect on the testosterone hormone which is most responsible for growth and development of male reproductive organs including the penis. When a man has normal testosterone levels, it helps him to maintain good energy level, mood, fertility and sexual desire. 
It is said to work because of the active ingredient Eurycoma Longifolia. This ingredient stimulates testosterone production and blocks the negative feedback cycle that occurs when the testosterone level is at its natural peak and therefore it is able to maintain a steady increase of testosterone.
Tongkat Ali Used for
Tongkat Ali is said to help men suffering from erectile dysfunction by increasing the man’s levels of testosterone. With this medication, the man should be able to maintain an erection and reach orgasm. It is also said to help increase interest in sex and to improve the quality and concentration of sperm in infertile men. There is some research for using tongkat ali for male sexual enhancement that has been promising.
There is very little evidence based on a few studies, but it also seems to improve symptoms in some other areas. According to examine.com, tongkat ali can show a minor increase in libido, a minor increase in subjective well-being, a minor increase in erections (based on self-reported studies), a minor increase in seminal motility, and a minor increase in sperm quality. There also seems to be a minor decrease in weight of overweight and obese men, but not in men or normal weight. There was also a minor increase in lean mass when paired with exercise, and a minor increase in power output. The studies show a minor decrease in stress and a minor decrease in cortisol.
It is also believed that the Tongkat Ali Root can help in other things but there is not a lot of evidence to back these claims. These include the claims that tongkat ali can boost athletic performance, help men who are involved in bodybuilding, and reduce body fat in men of normal weight. In some parts of the world it is also used for fever, ulcers, malaria, high blood pressure, bone pain, tuberculosis, cough, headache, syphilis, diarrhea, and even cancer, but there is also insufficient evidence to back these claims.
Tongkat Ali Dosage

The product websites suggest 200-300 mgs of a 100:1 extract which is about the same as 20-30 grams of the dry root, eurycoma longifolia. It is recommended to take between 1-4 capsules per day depending on the reviewer or seller. It is recommended to take it before each meal.

How to Use Tongkat Ali
Depending on different reviews and sellers, it is recommended to take about 20-30 grams before each meal, 3-4 times per day. Following the suggested 8 week regime of the seller’s website, the user should notice a changed in the testosterone level and body, and also should notice an increased sex drive. By the second week, the user should notice an improved recovery rate after working out. By the third week, the user should notice more aggressiveness toward the workout and possibly more aggressiveness or a shorter temper in general as a side effect due to the increased testosterone in the body. And by the last few weeks of the eight-week cycle, the user should be noticing top results in muscle mass as well as in the sex drive. Then the user should take a break of three to four weeks before starting the regime again. However the seller’s claims are not entirely supported by sufficient evidence.
To help with sexual health and libido, the seller’s website suggests taking the pills three to four times a day for five days, and then not taking any pills for two days, and repeating as the week goes on. Using this method, the seller claims that the user will see results in his libido, sperm count, duration, and overall sex drive.
