TestoPlex™ is a proprietary formula that includes synergistic, antioxidant-rich, bioactive extracts that support vitality and general physical and mental well-being. It features a patented green oat extract and unique mungbean sprout powder. Salivary assays have shown that the combination of ingredients in TestoPlex™ free up serum-bound testosterone, thereby optimizing availability of this crucially important hormone.*
The effectiveness of TestoPlex’s ability to increase testosterone levels has been evaluated by laboratory analyses. Chief among this formula’s benefits over pharmaceutical grade testosterone is that salivary assays following the use of TestoPlex at the recommended dose did not show an increase in estradiol or dihydrotestosterone. This conversion is likely inhibited by the rich content of apigenins which are among the 28 kinds of fl avonoids present in the Green oats (Swiss Oats A111™).
 Traditionally used for prostate health, nettle may have some association with sex hormone binding globulin and aromatase.
 Sea buckthorn contains lignans. Lignans block aromatase and 5-alpha reductase, sparing testosterone. Oats, nettle and buckthorn are known to contain neurotransmitters that improve mood.* As men age, testosterone levels decrease by approximately 1-2% annually.
Lower levels of this hormone have been associated with a decline in libido, weaker erections and/or a decreased ability to become erect, lack of energy, less strength &/or endurance, loss of height, decreased enjoyment in life, being sad or grumpy, less ability to play sports, falling asleep after dinner or decreased work performance.
 Five percent of males aged 40-50 years and perhaps as many as 70% of men over 70 years are confronted by these problems known clinically as “hypogonadism” and also referred to as “Andropause”.
*[6,7,8] The majority of testosterone (approximately 60%) is bound to sex hormone binding globulin. Of that considered bioavailable and the best indicator of male androgen status, approximately 38% is weakly bound to albumin and the remaining approximate two percent is known as “free” testosterone.* Against a background of earlier studies with Swiss Oats A111™ that showed signifi cant increases in free testosterone levels and signifi cant improvement in andropausal symptoms,
[9,10] XYMOGEN®, in partnership with Aeron Life Cycles Clinical Laboratory® confi rmed the efficacy of TestoPlex in a small study. The ADAM screening questionnaire (Androgen Defi ciency in the Aging Male) was administered for a baseline assessment of symptoms and repeated after one month.
 Saliva bioavailable testosterone was measured before and after supplementation by the Aeron SBA-T Assay.
 Extensive circadian testing was used to confi rm a 24-hour pattern of reduced testosterone output before supplementation, followed by an increase in bioavailable testosterone after two weeks of uninterrupted supplementation with TestoPlex. Measurement of salivary testosterone after further supplementation confi rmed increased levels in those men who had low levels prior to using the formula. Follow-up ADAM tests scores demonstrated symptomatic improvements.*
