Tongkat-Ali is sold as a powder and in capsules, and it is often combined with other herbs such as Horny-Goat-Weed in libido products. There are a number of tongkat ali extracts available in various potencies, and since each raw material supplier and manufacturer has a different way of preparing and extracting the raw tongkat ali root material, and since there are no established standards, it is difficult to give dosage recommendations that would be consistently effective. In addition to tongkat ali being available as a raw powder, it is sold as a 4:1, 5:1, 20:1 and a 100:1 concentration. An excellent and quite reliable source of the 100:1 extract is LJ100. At the higher tongkat ali concentrations, such as LJ100, it becomes difficult to dose appropriately since the margin of error in terms of effectiveness versus side effects becomes quite  challenging.  For more information on natural ways to treat erectile dysfunction.

LJ100 side effects
There are side effects to LJ100 when used in high doses. LJ100 side effects include increased body temperature, restlessness, irritability, and insomnia. When you buy a LJ100 supplement, keep this in mind and initially start with a dose no more than 25 mg. LJ100 should not be taken on the same day as Passion Rx or other sex herb formulas or other individual sex herbs since there could be overstimulation and restlessness. One of the side effects of high dose LJ100 is insomnia.

LJ100 extract pill questions
Q. I took 50 mg of LJ100 from another company and it made me very irritable. Does horny goat weed cause irritability too, what about maca extract?
   A. High doses of LJ100 can cause this side effect, and that is why we prefer people take smaller amounts. For more horny goat weed information. Maca is gentler and does not cause irritability as much except in high dosages.

Q. Just after taking 150 mg/day of Herbal Powers LJ100 capsules my platelet count jumped up to 681. Some claims are that Tongkat Ali increases red blood increase in bone marrow, so maybe it caused my high platelet count.
   A. It's difficult to make this connection bases on one blood study, but you may with to take a break from LJ100, test to see what your platelet level is, and then retake the LJ100 followed by retesting to see if it reoccurs. 150 mg of LJ100 is an extremely high dose.

Q.  I just purchased the Tongkat Ali LJ100 product labeled as "Club Natural" LJ100 capsules. I just started taking these LJ100 capsules and find the effects are better than a product I purchased from Sumatra Pasak Bumi from Indonesia. I have just been made aware of research from Malaysia that has shown Mercury and Lead in Tongkat Ali. Being a physician and having worked with patients toxic in environmental chemicals and metals, I am alarmed!! What research or analysis has been done on LJ100 product to assure that it is safe?
   A. If you visit the web page above for LJ100, there is a link that shows the certificate of analysis. LJ100 is a proprietary blend made by Herbal Powers and this is the version everyone uses when they mention LJ100 on the label of their LJ100 product.

Q. I saw an add for LJ200. What is this product, is LJ200 more potent than LJ100?
   A. We have not tested LJ200 so we don't know if it is effective. Also, LJ100 is a concentrated form of tongkat ali and it is quite potent, perhaps too potent. We don't see any need to concentrate tongkat ali any further. Therefore, for the time being, LJ200 is not an extract that we find necessary since the tongkat ali plain powder and LJ100 are quite sufficient on their own. Also, just because LJ100 says that it is 100 times an extract does not mean it is 100 times as potent as regular tongkat aii powder. If you take 400 mg of tongkat ali, you will realize how potent it is, actually most prefer taking less that 400 mg of the powder. Many products have 80 mg of LJ100 in them, and we feel that is too potent can can lead to unpleasant side effects. It is naive to claim that just because an LJ100 product has 80 mg or 25 mg of LJ100 that it is equivalent to 8000 mg of tongkat ali powder or 2500 mg of tongkat ali powder, respectively. It just doesn't work that way. Keep in mind, too, that tongkat ali has side effects and taking too much LJ100 or LJ200 can be counterproductive since these can cause insomnia. And when insomnia occurs, sex drive goes down.

Q. There is a website that claims that LJ200x has 185 mg of a concentrated extract equivalent to 37000 mg of regular tongkat ali powder. Is this true?
   A. If it were, and you took 37,500 mg of tongkat ali, I doubt you would be alive, or functioning properly. We find even 400 mg of tongkat ali powder to be quite a hefty dose. Anyone who makes this comparison apparently does not fully understand the tongkat ali herb and how the extracts are made. LJ200x is certainly not 200 times as potent as tongkat ali powder. We question the reliability of the information by whoever makes such statements.
     Often, tongkat ali works better in low doses than it does in high doses since side effects are common. Therefore, if you do buy LJ200x, begin with a portion of a capsule. Better yet, just try LJ100, there is much more research done with LJ100 than a lesser known and untested extract marketed as LJ200x.

Q. I just today purchased LJ100 and was given advice to stak it with Tribulus Fuel which is a testosterone booster. I was wondering how I should stak them together. My goal is to put on muscle mass .
   A. We are not familiar with tribulus fuel. LJ100 is quite potent and we suggest using it by itself, taking too many herbs the same day can cause insomnia and irritability. Lack of good sleep interferes with good hormone balance, interferes with growth hormone release and would be counterproductive. For muscle mass we suggest Creatine.

Q. I bought a bottle of LJ100 25 mg. I read the dosage like 1 capsule every other day or 3 times a week. My question is, can I not take LJ00 as needed, like viagra.
   A. Herbs are not like Viagra, they take a few days before working their best. You can take one capsule LJ100 in the morning every other day or 3 days a week and discuss with your doctor how to use Viagra. We suggest not taking Viagra the same day as LJ100. Viagra can be taken on a day when you are not taking LJ100 and it is better to use a smaller dose of Viagra than you normally do. LJ100 and many other sexual herbs have a delayed effect into the second and third day after taking a capsule.

Q. I recently purchased tongkat ali Extract 1:200 200 caps @ 600 mg of Tongkat Ali from Indonesia and I'm not sure if it is working or not. Base on your website taking that amount of this extract I would think I would know. Not sure whether to purchase from them again. What is your opinion?
   A. We have no idea what this product would contain. If it is true 200:1 tongkat ali extract, it should have an effect.

Q. I just received my first bottle of LJ100 25Mg made by Club Natural and the instructions say 2 to 4 capsules per day yet your website says to take much less. I took 2 capsules before I saw your website. for the future what should be my regimen?
   A. There are different viewpoints on how to take LJ100, we prefer starting slow with one capsule every other day and have a gradual enhancement rather than shocking the system too quickly with a potent herb. However, there are individuals who need a high dose to feel an effect, for these rare individuals, 2 capsules of LJ100 may be more appropriate.

Q. Does LJ100 increase genital sensation?
   A. Many sexual herbs can increase genital sensation, including LJ100.

Q. I am a health food store owner and received marketing material that LJ100 has anti-aging-enhance IGF-1, enhances sports performance, improves sexual function, increases energy, and helps with weight loss. Are any of these true?
   A. LJ100 does enhance sexual function, does increase energy )but we don't know if this is sustained over time), I am not sure about the weight los part, but I do not believe it has anti-aging potential and do not think it enhances sports performance since it increases body temperature which may be counterproductive.

Q.  Can you please tell me the correct dosage of tongkat ali lj100.The bottles in my first order suggested 2 to 4 capsules daily with water and a meal, My recent order says one capsule daily in the morning on an empty stomach, can you please clarify this for me.
   A. There is no standard LJ100 dosage that works for everyone, hence we suggest starting with a low amount and then seeing how this affects you before taking a larger dose.

Q. I tried Tongkat Ali LJ100 80mg. After just 1 tablet, I began to sweat and have palpitations pretty much relieved with propranolol within a few hours. This was followed with aggressive thoughts and insomnia. I took no more tablets yet these symptoms continued for several days. At the end of a week, my testicle volume (I would estimate) increased by
200%, and sex and aggressiveness dominated my thoughts. Midway through the week I visited my physician to see what was going on and to document this. My liver enzymes were substantially elevated. Testosterone was, surprisingly, not at all elevated when compared to a previous test. I do not know about causality on this. It could be that the Tongkat Ali was the cause, or (I believe) that perhaps the liver was damaged from some unknown cause (no Hep A, B or C) which prevented the active components of the herb from being metabolized and cleared at a normal
rate. Figured that you should know, so that you can add this to your warning. Oh, and my liver function has returned to normal. This took several months.
   A. LJ100 is very potent and that is why when Dr. Sahelian formulated his product on LJ100 he only included 25 mg as opposed to the standard 80 mg being used currently by many companies. It is difficult to imagine that liver enzymes would be so influenced by one dose of LJ100, but we still don't know enough about this herb to have a clear idea on how it influences liver enzymes.

Q. I had been taking 25 mg of DHEA for a couple of years straight, no noticeable side effects. I'm not sure if it helped
either, but my testosterone levels have been better from blood tests at my physician than they had been. My question is: Can I take a low dose (5 - 10 mg per day) of DHEA and LJ100 25 mg, or LongJax 20:1/400 mg on the same day? Or should I not take DHEA the same day that I take any Tongkat Ali product? What helps more in terms of maintaining testosterone levels? DHEA itself (without LJ100 or any Tongkat Ali product), or simply using the herbal products (LJ100, LongJax, or Tongkat Ali powder/capsules)?
   A. We can't advise what a person should do, but there is a risk of increased side effects from taking too high doses or DHEA or potent aphrodisiacs such as LJ100.

LJ100 Press Release - August 2006
A new study has demonstrated that LJ100 Eurycoma longifolia extract, standardized to 40% glycosaponins and 22% eurypeptides, known for enhancing sexual virility and overall physical endurance in men by increasing levels of free testosterone, may be equally as viable for promoting anabolic action during and after endurance training or competition. The study by S. Talbott, et al, entitled, “Effect of Eurycoma longifolia Extract on Anabolic Balance During Endurance Exercise,” sought to determine the effects of the herb specifically on cortisol and testosterone levels during high-intensity exercise. The researchers used a freeze-dried extract of eurycoma longifolia that was standardized to contain 22 percent eurypeptides and 40 percent glycosaponins. Participants were men who were taking part in a 24-hour mountain bike event. The subjects provided a saliva sample prior to and after each of four 14-mile laps; the eight samples of each participant underwent an enzyme immunoassay (Salimetric, State College of PA) to determine and compare levels of cortisol and testosterone. This was compared to placebo samples. Both placebo and supplement were taken approximately 30 minutes prior to exercise. The researchers found that cortisol levels in the LJ100 Eurycoma group were lower – 33 percent – than in the placebo group. Also, testosterone levels in the supplement group were 16 percent higher than that of the placebo group.
     About LJ 100 - LJ100 is a registered standardized, freeze-dried Eurycoma longifolia extract, containing 40% glycosaponins and 22% eurypeptides, a bioactive glycoprotein that is now clinically proven for its androgenic properties. LJ100 has undergone a patented BAT extraction process to capture 22% biologically active eurypeptides, proven in research to be responsible for increasing libido. Created by the original researchers at the Forest Research Institute of Malaysia (FRIM), University of Malaya, and Massachusetts Institute of Technology, LJ100 (22% bioactive eurypeptides) has shown - in human clinical trials - an ability to increase DHEA and free testosterone, decrease sex hormone binding globulin (SHBG), modulate cortisol, and increase IGF-1 level.
     About Herbal Powers Ingredients - Based in Bradenton, FL, Herbal Power Ingredients is a an herbal health company focused on bringing effective herbal remedies from Asia to the North American market.
     Comments: LJ100 does work for libido enhancement, but LJ100 side effects can occur with higher doses. People should use LJ100 cautiously and in low doses. I have included this press release here, but I do question the interpretation of the findings. I am not convinced LJ100 is appropriate for endurance exercise, and I don't think the changes in cortisol or testosterone significant. in any practical sense. At this point, I am not sure what glycosaponins and eurypeptides really are and who coined these terms.
