Questionnaires Analysis
Analysis of the SHI-Questionnaire results have shown that 62% of the cases had either increased or a maximum score after consuming LJ100. Another 24% showed reduction while 14% of the cases showed no change in the score (Figure 1). This indicates that the majority of the volunteers demonstrated an increase in their sexual health satisfaction and performance. Breakdown of the SHI-Questionnaire showed subjects has an increase in sexual desire and the success at the attempts at sexual intercourse.

PADAM Analysis
Analysis of the PADAM Score demonstrated that 82% of the cases showed a decrease in total score (decrease is positive effect). There is 91% improvement in the sexual PADAM score component, a 73% improvement in the physical component, and an 82% improvement of psychological component. The vasomotor score showed improvement in 50% of the subjects (Figure 2). The improvements in the first three components of the PADAM score reflects that consumption of LJ100 had resulted in an improvement of their quality of life with regards to their physical, sexual and psychological well being.

Serum Hormones analysis
Testosterone
Total testosterone levels were not significantly different between those raised (43%) and those declined (39%) in this study (Table 1). This gives an initial impression that LJ100 does not have any effect on steroidogenesis. Considering that almost all the volunteers have normal levels of total testosterone, the feedback system is activated to ensure the testosterone levels are within the individual needs range. In 6 volunteers whose serum total testosterone is low, there is an increase in total testosterone on first and third week as well as improvement in the Quality of Life Scores (SHI-Q and PADAM Score).
DHEA
Analysis of the DHEA showed gradual increase from 26% after 1 week to 47% after 3 weeks. This suggests that LJ100may influence the DHEA production, which subsequently would be aromatized to testosterone (Figure 3).

SHBG Analysis
The results showed that SHBG levels were reduced in 36% of the cases after one week and improved to 66% after 3 weeks. This suggests that LJ100 could have an effect on the production of SHBG (Table 2).
Free Testosterone Index Analysis (FTI)
When the SHBG level declines, the Free Testosterone Index (FTI is calculated as a percentage of the total testosterone against SHBG) goes up. Results demonstrated that the FTI increased in 39% of the subjects after 1 week to 73% after 3 weeks (Table 3)
Conclusion
Increasing testosterone is the key factor in increasing sex drive. Testosterone is the most important of the male sex hormones, known as androgens, produced in the gonads. Testosterone plays a key role in the development and maturity of male sex organs. The hormone promotes secondary sex characteristics, including the appearance of facial hair, sexual desire, and sexual behavior. However, testosterone is not just a sex booster for men. Women also produce testosterone, about 5 to 10 percent the amount produced in men. In woman, this vital hormone also stimulates sex drive and produces heightened sensitivity of erogenous zones.
In this study, the aqueous LJ100 extract has a strong potential in providing sufficient free testosterone to the body as demonstrated by the increase in the free testosterone index between weeks one and three. The high score in the Physical and Sexual Domain of PADAM and the Desire and Sexual Attempts in the SHI-Q score suggests this extract can delivery sexual health effects for both men and women.
The results demonstrated that the circulating androgen concentration affects SHBG synthesis. The increase in DHEA levels (DHEA is a precursor to testosterone) between week 1 and week 3 resulted in elevated testosterone levels that caused a decrease in SHBG levels. It is important to note the any decrease in SHBG levels has an overall effect to increase free testosterone index as indicated in table 3. The results of this study suggest that LJ100 inhibits SHBG allowing more free testosterone to remain in the blood. This additional testosterone stems the aging process, improves energy and sexual function, and helps reduce body fat and reduces the risk factors associated with heart health.
Since this study is just an exploratory study to look into the marketing potential of LJ100, the volunteers were asked about personal feedbacks with regard to the extract. The following responses were received:
48% felt that they are feeling healthy, not easily tired, feeling active and energized.
40% felt easily aroused, increase sexual desire and maintained an erection longer.
16% felt their joints and backache are feeling better.
24% felt warm and easily sweat (sign of better circulation)
8% experience better sleep.
8% felt an improvement in their memory.
20% felt their appetite has improved and their bowel movements are better than before.

LJ100™ Saliva Testosterone Test
Saliva Testosterone Test of 9 Individuals 26-52 years of age
Dosage 2x2 (50mg/capsules) morning & evening for 10 days
Normal range for athlete 800 = 150ng/dl of blood
Volunteers 1-5 are athletes - data are an average of 3 different studies at different times
Volunteers 6-9 do not exercise on a regular basis
Conclusion
The results demonstrate that 100 mg per day of LJ100 caused an increase in bioavailability testosterone within 10 days. Furthermore, all subjects (athletes and non-athletes) showed a positive increase in testosterone suggesting that LJ100 causes an increase in the free testosterone index.

Eurycoma longifolia, commonly known as “Tongkat Ali” or “Longjack,” is often touted as a testosterone “booster” and marketed to athletes as a training aid and performance enhancer. Rodent studies have shown oral delivery of Eurycoma extract to improve sexual performance and increase serum testosterone levels. Open-label human trials have suggested that Eurycoma extract may help prevent age-associated androgen deficiency, improve sexual function, and increase psychological parameters such as mood, energy, and sense of well-being. The purpose of this study was to determine the effects of Eurycoma longifolia on testosterone and cortisol levels during intense endurance exercise. We used a water-soluble extract of Eurycoma longifolia (E) standardized to 22% eurypeptides and 40% glycosaponins. Male subjects (N=30) were recruited from a 24-hour mountain biking event and asked to provide a saliva sample before and after each lap for measurement of cortisol and testosterone by enzyme immunoassay (Salimetrics, State College, PA). Subjects completed 4 laps (14.91 miles/lap) and provided 8 saliva samples over a 24h period. Subjects consumed 100mg of E or a look-alike placebo (P) approximately 30 minutes prior to endurance exercise. Cortisol levels were 32.3% lower in E compared to P (0.552+0.665 versus 0.816+0.775 ug/dL, P < 0.05). Testosterone levels were 16.4% higher in E compared to P (86.72+40.90 versus 72.47+33.77 pg/mL, P < 0.05). These results suggest that Eurycoma longifolia extract may help to maintain normal levels of cortisol (low) and testosterone (high) and thus promote an overall “anabolic” hormonal state (versus a “catabolic” state characterized by elevated cortisol and suppressed testosterone) during intense endurance exercise.
