About this study
Official title: Influence of Purity Product Supplements on Muscular Strength, Serum Testosterone Levels, Sexual Function, and Quality of Life
Decreased muscle mass (sarcopenia) and strength (dynapenia) are common during aging, with a rate of muscle mass loss that is approximately 6% per decade between 30 and 70 years of age. Muscle mass loss results in reduced strength and physical function (frailty), increased risk for falls and bone fractures, and decreased quality of life. The age-related decrease in testosterone plays a key role in the loss of muscle mass and strength for aging males. There is increasing interest in nutritional and exercise strategies to prevent aging-related losses in muscle mass and strength. Sexual dysfunction has a high prevalence among men (31%), and include erectile difficulties (10%), lack of interest in sex (9%), and inability to achieve orgasm (7%). There are multiple causes including low testosterone. There is growing interest in natural supplements, and this study will compare under double blind procedures two natural supplements with placebo (Men's Perfect Multi Formula and Andro Vitality) that have been formulated by Purity Products. The supplements contain micronutrients, plant extracts, and herbs, with the primary bioactives Rhaponticum carthamoides and magnesium. Rhaponticum carthamoides, commonly known as maral root or Russian leuzea, is a perennial herb that grows in South Siberia, and has been used to enhance muscular and sexual function, but more evidence from properly designed human trials is needed to determine both efficacy and safety. The purpose of this study using a randomized, parallel group design, is to evaluate the effect of two supplements relative to placebo on strength, serum free and total testosterone levels, sexual function, mood state, and quality of life compared to placebo over a 6-week period in 120 males.

STUDY PARTICIPANT RECRUITMENT:
Subjects will be recruited via mass advertising in the Charlotte Metropolitan area. Healthy subjects will be screened during recruitment to determine study eligibility (via email and phone). The Charlotte metropolitan area is the largest in the Carolinas, and the sixth largest metropolitan area in the Southeastern region of the United States. Male participants 40 to 70 years of age will be selected who match the listed inclusion and exclusion criteria (next page). The planned distribution of participants by racial/ethnic groups will reflect the demographics of the metropolitan area [White non-Hispanic (60%), Black non-Hispanic (24%), Hispanic (10%), and Asian or Pacific Islander non-Hispanic (3.5%)]. Those subjects who meet all of the inclusion criteria and none of the exclusion criteria will be enrolled and randomized into the study. The study duration for each subject will be 6 weeks. There will be a total of 3 visits for this study. Following recruitment, there will be a 2-week washout period for PDE5 medications. At each of the three morning visits (7:00-9:00 am), subjects will fill in the symptom log (retrospective 3-week period) and have their blood drawn to analyze serum levels of free and total testosterone, and to be tested for strength (isometric hand grip, leg/lower back, YMCA bench press) and body composition (8-point bioelectrical impedance). All subjects will be required to fast overnight for at least 9 hours prior to each visit. Subjects will also be required to abstain from all vigorous exercise and sexual activity at least 24-hours prior to each visit. Within three days prior to each lab visit, subjects will use Survey Monkey via the Internet to fill in responses to three questionnaires: CSFQ, WHO-QOL, and POMS.
RESEARCH PLAN A. V1 - Baseline Visit - Week 0 Prior to the first lab visit, subjects will be recruited according to the listed inclusion and exclusion criteria. Subjects who agree to participate in the study, will be sent the Informed Consent Document (ICD) for review and signature. Subjects will fill in the Medical Health Questionnaire (MHQ) via Survey Monkey to obtain demographic, lifestyle, and medical histories. Following recruitment, there will be a 2-week washout period for PDE5 medications. Within three days prior to the first lab visit, subjects will supply responses to the CSFQ, WHO-QOL, and POMS Questionnaires via Survey Monkey. The compensation contract will be reviewed and signed.
- Informed Consent: At the first lab visit (V1), all subjects will review the Informed Consent Document (ICD) that was previously sent via email attachment, and receive a signed copy.
- Questionnaires: Responses to the CSFQ, WHO-QOL, and POMS questionnaires sent prior to the first lab visit via Survey Monkey will be reviewed for completeness. Subjects will fill in the symptom log.
- Blood Sample: Subjects will have their blood drawn for analysis of free and total testosterone. Subjects will be asked to come in to the clinic during the early morning having fasted for at least 9 hours prior to the visit and refrained from having sexual intercourse 24 hours prior to the visit.
- Anthropometric and Strength Measures: Subjects will be measured for height and weight, and percent body fat using 8-point BIA. Handgrip and leg/lower back strength will be assessed with dynamometers (Figure 3). Subjects will also be tested for upper body strength using the YMCA bench press test (reps with 80-pound barbell set with a metronome for 30 lifts per minute).
- Randomization and Study Product Dispensing: Subjects will be assigned a randomization number, and receive a 3 week supply of the study product. The study product will be contained in supplement trays with specific dates and instructions applied. Subjects must return the supplement trays at the next two lab visits to verify compliance with the dosing regimen.
- V2 -Mid-Study Visit (Week 3)
- Retrieval Procedures: Subjects will return their supplement tray and any unused study product.
- Intercurrent Medical History and Concomitant Medication History: Subjects will be interviewed by the clinic staff to determine whether there have been any changes in their medical history, whether they have started taking any new medications.
- Questionnaires: Responses to the CSFQ, WHO-QOL, and POMS questionnaires sent within 3-days prior to the second visit via Survey Monkey will be reviewed for completeness. Subjects will fill in the symptom log (3 week retrospective).
- Blood Sample: Subjects will have their blood drawn for analysis of free and total testosterone. Subjects will be asked to come in to the clinic during the early morning having fasted for at least 9 hours prior to the visit and refrained from having sexual intercourse and all exercise 24 hours prior to the visit.
- Anthropometric and Strength Measures: Subjects will be measured for weight, and percent body fat using 8-point BIA. Handgrip and leg/lower back strength will be assessed with dynamometers, and upper body strength with the YMCA bench press test.
- Study Product Dispensing: Subjects will receive their final 3-week supply of the study supplements. Subjects must return the supplement tray at the final lab visit to verify compliance with the dosing regimen.
- V3 -End-of-Study Visit (Week 6)
- Retrieval Procedures: Subjects will return their supplement tray and any unused study product.
- Intercurrent Medical History and Concomitant Medication History: Subjects will be interviewed by the clinic staff to determine whether there have been any changes in their medical history, whether they have started taking any new medications.
- Questionnaires: Responses to the CSFQ, WHO-QOL, and POMS questionnaires sent within 3 days prior to the final lab visit via Survey Monkey will be reviewed for completeness. The final symptom log will be completed. The compensation contract will be reviewed.
- Blood Sample: Subjects will have their blood drawn for analysis of free and total testosterone. Subjects will be asked to come in to the clinic during the early morning having fasted for at least 9 hours prior to the visit and refrained from having sexual intercourse 24 hours prior to the visit.
- Anthropometric and Strength Measures: Subjects will be measured for height and weight, and percent body fat using 8-point BIA. Handgrip and leg/lower back strength will be assessed with dynamometers, and upper body strength with the YMCA bench press test.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Decreased muscle mass (sarcopenia) and strength (dynapenia) are common during aging, with a rate of muscle mass loss that is approximately 6% per decade between 30 and 70 years of age. Muscle mass loss results in reduced strength and physical function (frailty), increased risk for falls and bone fractures, and decreased quality of life. The age-related decrease in testosterone plays a key role in the loss of muscle mass and strength for aging males. There is increasing interest in nutritional and exercise strategies to prevent aging-related losses in muscle mass and strength. Sexual dysfunction has a high prevalence among men (31%), and include erectile difficulties (10%), lack of interest in sex (9%), and inability to achieve orgasm (7%). There are multiple causes including low testosterone. There is growing interest in natural supplements, and this study will compare under double blind procedures two natural supplements with placebo (Men's Perfect Multi Formula and Andro Vitality) that have been formulated by Purity Products.
