Mi incuriosiva questo prodotto, sia perchè nn ho capito se sono solo steroli vegetali e per i risultati degli studi.
Cosa sono gli ingredineti??

Rationale: In healthy men, it is known that blocking estrogen formation stimulates the HPT axis to increase in vivo testosterone production. Recently, a new class of dietary supplements has appeared that claim to inhibit the aromatase enzyme (i.e., decrease the transformation of aromatizable androgens [androstenedione, DHEA, testosterone] into estrogens [estriol, estrone, estradiol]), thus stimulating an increase in testosterone formation.
Purpose: The purpose of this pilot study was to examine the effects of a popular aromatase inhibitor, Novedex XTÔ (NOV-XT), on selected hormonal responses (total testosterone [TT], bioavailable testosterone [BT] and estradiol [E2]), as well as serum and plasma markers of renal, hepatic, and hematological function.
Methods: Using an open-label, proof-of-concept design, five eugonadal men (mean ± SD age, height, weight, body fat: 31.6 ± 2.8 yr, 174.3 ± 1.8 cm, 84.3 ± 3.8 kg, 11.2 ± 3.3 %) ingested 4 capsules of NOV-XT prior to bed for 28 consecutive days. According to the manufacturer, each capsule of NOV-XT contains 60 mg of a proprietary blend of three naturally-occurring aromatase inhibitors: 6, 17-keto-etiocholeve-3-ol tetrahydropyranol, 3, 17-keto-etiochol-triene, and 3’,5,7-trihydroxy-4’-methoxyflavone (supplements were provided by an FDA-registered, pharmaceutically licensed manufacturer; confirmation by an external laboratory is pending). Blood samples obtained at baseline (prior to supplementation), and at weekly intervals thereafter for 28 days, were analyzed for TT, BT, and E2 by radioimmunometric and chemilluminetric assays. Subjects were required to maintain their normal dietary and training patterns during the study. All blood samples were obtained at the same time of day (0700-0900) to minimize diurnal variation. Hormone concentrations were statistically analyzed by ANOVA and Tukey’s HSD post-hoc test. Dependent t-tests were used to compare changes in blood chemistries. Statistical significance was accepted at p<0.05.
Results: Compared to baseline, NOV-XT administration rapidly and significantly increased TT and BT. Mean changes from baseline for TT after one, two, three, and four weeks of NOV-XT administration were: +145% (p<0.006), +183% (p<0.0005), +232% (p<0.0002), and +240% (p<0.0002), respectively. Mean changes from baseline for BT after one, two, three, and four weeks of NOV-XT administration were: +300% (p<0.01), +402% (p<0.0009), +511% (p<0.0002), and +528% (p<0.0002), respectively. Despite these large increases in TT and BT, no significant aromatization to estradiol occurred (i.e., E2 concentrations remained unchanged). No significant changes in clinical blood chemistries (fasting glucose, BUN, creatinine, bilirubin, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, sodium, potassium, chloride, calcium, albumin, globulin, CO2, total protein, total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol) or systemic hemodynamics (heart rate, systolic blood pressure, diastolic blood pressure) were observed, nor were any adverse events noted during the study.

Data are reported as mean (± SD). * indicates significantly different from corresponding baseline value. Bio T = bioavailable (free+weekly bound) testosterone, BUN:Cr = blood urea nitrogen:creatinine ratio, ALP = alkaline phosphatase, AST = aspartate aminotransferase, ALT = alanine aminotransferase, Chol = total cholesterol, TAG = triglycerides, HDL = high density lipoprotein, LDL = low density lipoprotein, SBP = systolic blood pressure, DBP = diastolic blood pressure.
Conclusions:Within the framework of the current experimental design, these preliminary data indicate that four weeks of NOV-XT supplementation significantly elevates serum TT and BT, likely via the inhibition of estradiol formation. Further, NOV-XT does not appear to result in any deleterious effects on blood chemistry or systemic hemodynamics in healthy, eugonadal men. Future research is necessary to confirm and refine these results in a larger sample size, as well as examine the impact of NOV-XT on androgenic and estrogenic metabolites, body composition, and muscular performance.

In yet another (the 3rd) independent clinical research study, Novedex XT® shows why it is rightfully known as the #1 Testosterone Modulating Supplement of All Time and why it is the #1 Selling Testosterone Modulating Supplement... EVER! No other “supposed testosterone modulating” supplement has even one, never mind THREE (3) independent clinical research studies conducted on it to demonstrate that it works and is safe like Novedex XT® does. If the other guy’s supplements do not have any studies to show their product works, how do they know it works? More importantly, how do YOU know it works? Who wants to spend hard earned money for a “maybe?” In this landmark 11 week independent clinical trial conducted by Dr. Darryn Willoughy at Baylor University, Novedex XT® did not cause any significant changes in any Serum Clinical Chemistry Markers (including liver studies and cholesterol/HDL/LDL) or Urine Clinical Safety Markers or even in PSA – a significant clinical marker for prostate health! But Novedex XT® did cause an average of 600%+ increase in free testosterone! This change is so dramatic that if you are a “tested athlete” we strongly suggest that you discuss use of Novedex XT® with your sanctioning body before using it. With results this powerful, you might be wrongfully accused of “cheating.” Even more importantly, all of the clinical parameters checked, including LH/FSH and GH, everything returned back to baseline (normal) levels within 21 days of discontinuation of Novedex XT® showing that even using Novedex XT™ for 60 days straight does not “shut you down” when you come off of it.
