What the research says about the ingredients in Rocket T Testosterone Recharge

Peer-reviewed studies and reviews on the individual ingredients - Testofen fenugreek, KSM-66 ashwagandha, magnesium, zinc, vitamin B6 and vitamin D3 - shared for education, not as claims about this finished product. Rocket T's own claims are the uses authorized under its Natural Health Product licence, NPN 80117277.

Testofen Fenugreek & Testosterone

A 12-week trial found fenugreek raised saliva testosterone versus placebo

In a double-blind, randomized, 12-week trial of 95 men (40-80y) taking a standardized fenugreek extract, plasma and saliva testosterone rose at every dose versus baseline, and the 1800mg dose significantly increased saliva testosterone (19.6%) versus placebo - the free-testosterone index also rose significantly at the highest dose.

Human RCT
Lee-Odegard et al., PLoS One (2024)
Testofen Fenugreek & Testosterone

An 8-week trial found a fenugreek-based extract raised total and bioavailable testosterone

In a double-blind, randomized trial of 30 resistance-trained men taking 500mg/day of a fenugreek-derived extract for 8 weeks alongside a supervised training program, total and bioavailable testosterone increased significantly compared with placebo, alongside a significant reduction in percent body fat.

Human RCT
Wilborn et al., International Journal of Sport Nutrition and Exercise Metabolism (2010)
Testofen Fenugreek & Testosterone

An honest counterpoint: fenugreek did not improve BPH symptoms, hormones stayed normal

In a 12-week, double-blind, placebo-controlled trial of 100 men with benign prostatic hyperplasia (BPH) symptoms, a standardized fenugreek extract (600mg/day) did not improve urinary symptom scores versus placebo - though testosterone, free testosterone, SHBG and PSA all remained unchanged and within normal limits throughout, adding to the ingredient's safety profile.

Human RCT
Rao & Grant, Phytotherapy Research (2019)
Testofen Fenugreek, Libido & Male Vitality

Testofen improved sexual function and raised testosterone in aging men

In a 12-week, double-blind, randomized, placebo-controlled trial of 120 healthy men aged 43-70, 600mg/day of Testofen (a standardized Trigonella foenum-graecum seed extract) significantly reduced Aging Male Symptom scores, improved sexual function including morning erections and frequency of sexual activity, and increased both total and free serum testosterone versus placebo.

Human RCT
Rao et al., The Aging Male (2016)
Testofen Fenugreek, Libido & Male Vitality

A fenugreek + mineral formulation improved physiological libido

In a 6-week, double-blind, randomized, placebo-controlled trial of 60 healthy men, 600mg/day of Testofen combined with magnesium, zinc and pyridoxine (vitamin B6) significantly improved libido subdomains of sexual arousal and orgasm and self-reported satisfaction with energy and well-being, while serum testosterone and prolactin remained within the normal reference range throughout.

Human RCT
Steels, Rao & Vitetta, Phytotherapy Research (2011)
Testofen Fenugreek, Libido & Male Vitality

A Testofen-containing supplement drink improved libido alongside erectile function

In a randomized, double-blind, placebo-controlled crossover pilot study of 20 men with sexual dysfunction already using PDE5 inhibitors, a supplement drink containing Testofen (600mg/day) plus L-citrulline, resveratrol and caffeine significantly improved multiple International Index of Erectile Function domains, including desire frequency and orgasm frequency, with no adverse events.

Human RCT
Shirai et al., World Journal of Men's Health (2020)
KSM-66 Ashwagandha, Testosterone & Strength

8 weeks of ashwagandha significantly increased testosterone and strength gains

In an 8-week, randomized, double-blind, placebo-controlled trial of 57 young men undergoing resistance training, 300mg of ashwagandha root extract twice daily produced significantly greater gains in muscle strength (bench press, leg extension), muscle size and serum testosterone (+96.2 ng/dL vs +18.0 ng/dL for placebo) compared with placebo.

Human RCT
Wankhede et al., Journal of the International Society of Sports Nutrition (2015)
KSM-66 Ashwagandha, Testosterone & Strength

A systematic review found ashwagandha raised testosterone and LH in infertile men

A systematic review and meta-analysis of Withania somnifera in male infertility found 90 days of treatment increased serum testosterone by 17% and luteinizing hormone by 34% versus baseline in oligospermic men, alongside improved sperm concentration and motility, though the authors noted the evidence base remains limited and called for larger, high-quality randomized trials.

Systematic review
Durg, Shivaram & Bavage, Phytomedicine (2018)
KSM-66 Ashwagandha, Testosterone & Strength

An honest nuance: testosterone rose over time but not significantly versus placebo

In a 60-day, randomized, double-blind, placebo-controlled trial of 60 stressed adults, 240mg/day of a standardized ashwagandha extract (Shoden) significantly reduced anxiety and morning cortisol versus placebo; testosterone increased significantly in men over time, but this change was not statistically significant compared with the placebo group - a balanced finding rather than an overstated one.

Human RCT
Lopresti et al., Medicine (2019)
KSM-66 Ashwagandha & Stress Resistance

A classic 60-day trial cut stress scores and cortisol

In a randomized, double-blind, placebo-controlled trial of 64 adults with chronic stress taking 300mg of a high-concentration ashwagandha root extract twice daily, stress-assessment scores and serum cortisol were both significantly reduced versus placebo after 60 days, with only mild, comparable adverse effects in both groups.

Human RCT
Chandrasekhar, Kapoor & Anishetty, Indian Journal of Psychological Medicine (2012)
KSM-66 Ashwagandha & Stress Resistance

A 60-day trial reduced cortisol and increased serotonin

In a randomized, double-blind, placebo-controlled trial of 54 adults, 500mg/day of a standardized ashwagandha root extract with piperine significantly improved perceived stress, anxiety and quality-of-life scores versus placebo, alongside a significantly greater reduction in morning salivary cortisol and an increase in urinary serotonin.

Human RCT
Majeed, Nagabhushanam & Mundkur, Medicine (2023)
KSM-66 Ashwagandha & Stress Resistance

Ashwagandha stabilized stress biomarkers in athletes during pre-season training

In a 42-day randomized, placebo-controlled trial of 56 team-sport athletes, 600mg/day of ashwagandha root extract stabilized cortisol/cortisone increases seen in the placebo group, improved recovery-perception scores and reduced muscle soreness in female athletes, and improved countermovement jump performance in male athletes during pre-season training.

Human RCT
Coope et al., Nutrients (2026)
Zinc & Male Reproductive Health

Zinc restriction lowered testosterone; supplementation raised it in a classic study

In normal young men, four months of dietary zinc restriction was associated with a significant decrease in serum testosterone, while six months of zinc supplementation in marginally zinc-deficient older men significantly increased serum testosterone from 8.3 to 16.0 nmol/L - directly demonstrating zinc's role in modulating testosterone levels.

Human study
Prasad et al., Nutrition (1996)
Zinc & Male Reproductive Health

A meta-analysis found zinc improved sperm concentration and motility

A systematic review and meta-analysis of randomized trials on nutrients and dietary supplements for sperm quality found zinc supplementation significantly increased total sperm concentration and total sperm motility compared with placebo, one of several minerals showing a measurable benefit.

Meta-analysis
Salas-Huetos et al., Advances in Nutrition (2018)
Zinc & Male Reproductive Health

A network meta-analysis ranked zinc among the most effective fertility nutrients

A network meta-analysis of 69 studies on nutritional therapies for male infertility found zinc supplementation significantly improved pregnancy rates (risk ratio 5.39), second only to L-carnitine with micronutrients, particularly in men with oligozoospermia.

Network meta-analysis
Zafar et al., Drugs (2023)
Magnesium, Testosterone & Exercise

Magnesium supplementation increased free and total testosterone in athletes

In a 4-week controlled trial of taekwondo athletes and sedentary controls, magnesium supplementation (10mg/kg body weight) increased both free and total plasma testosterone at rest and after exhaustion, with the increase being larger in athletes who exercised than in sedentary subjects.

Human study
Cinar et al., Biological Trace Element Research (2010)
Magnesium, Testosterone & Exercise

Magnesium levels were strongly linked to testosterone in a cohort of older men

In a cohort of 399 men aged 65 and older, serum magnesium was positively and independently associated with total testosterone and IGF-1 after adjusting for BMI, inflammation, SHBG and other anabolic/catabolic markers, suggesting magnesium status is a determinant of anabolic hormone levels in aging men.

Cohort study
Maggio et al., International Journal of Andrology (2011)
Magnesium, Testosterone & Exercise

An honest counterpoint: magnesium supplements offer little benefit once status is normal

A review of magnesium and exercise concluded that when plasma magnesium levels are already within the normal range, supplementation offers no significant additional performance benefit, and that the popular use of magnesium for exercise-related muscle cramps is likely exaggerated - a useful balance against overstating the mineral's effects.

Review
Bielinski, Revue Medicale Suisse (2006)
Vitamin D & Testosterone

A meta-analysis found small but significant testosterone gains from vitamin D

A systematic review and meta-analysis of 11 studies (1,168 infertile men) found oral vitamin D supplementation was associated with small but statistically significant improvements in semen volume, sperm concentration, progressive motility and serum testosterone, though it found no significant effect on clinical pregnancy or live-birth rates.

Meta-analysis
Zhang et al., PeerJ (2026)
Vitamin D & Testosterone

Vitamin D raised the testosterone-to-LH ratio in vitamin D-insufficient men

In a randomized, double-blind, placebo-controlled trial of 307 infertile men, vitamin D plus calcium supplementation did not change sex steroids overall, but in the predefined subgroup with vitamin D insufficiency (25OHD under 50nmol/L), vitamin D-treated men had a significantly higher testosterone/LH ratio than placebo - suggesting Leydig cell function depends on adequate vitamin D status specifically when levels are low.

Human RCT
Holt et al., Andrology (2023)
Vitamin D & Testosterone

Serum vitamin D correlated with testosterone and semen quality

In a cross-sectional study of 260 men, serum vitamin D concentration was significantly lower in men with seminal abnormalities and was positively correlated with total testosterone levels as well as sperm concentration and motility, independent of other variables.

Cohort study
Ciccone et al., Asian Journal of Andrology (2021)
Vitamin B6 & Formula Considerations

Vitamin B6 is a coenzyme for over 160 metabolic reactions

A scoping review for the Nordic Nutrition Recommendations describes pyridoxal-5-phosphate (the active form of vitamin B6 used in this formula) as a coenzyme for more than 160 different enzymatic reactions in the metabolism of amino acids, carbohydrates, lipids and neurotransmitters.

Review
Bjorke-Monsen & Ueland, Food & Nutrition Research (2023)
Vitamin B6 & Formula Considerations

A classic clinical trial found B-complex vitamins delayed fatigue in heat

An early clinical trial of water-soluble vitamin therapy, including pyridoxine (vitamin B6), found supplementation delayed the onset of fatigue during physical activity performed in hot climatic conditions compared with controls.

Human study
Early & Carlson, Int Z Angew Physiol (1969)
Vitamin B6 & Formula Considerations

An honest caution: most commercial 'testosterone booster' supplements lack evidence

A review of 50 commercial 'testosterone booster' supplements found only 24.8% had any published data supporting a testosterone increase, and that many products - across ingredient categories including vitamin B6, zinc and magnesium, the same categories in this formula - contained supra-therapeutic doses, some exceeding the FDA's upper tolerable intake level; a useful reminder to favour standardized doses and real ingredient transparency over marketing claims.
