Driven by this commitment, our journey to search for ingredients that boost testosterone secretion began.
Male Menopause (Andropause)
Male menopause is a condition caused by a decline in testosterone—the primary male hormone—leading both physical and mental imbalances. It is said that one in six over 40 male has this condition and it is becoming a social concern globally.
Triggered mainly by primarily by social stressors such as interpersonal issues or retirement, this condition gives rise to physical, mental and sexual symptoms including persistent fatigue and low mood.
According to global data, more than 480,000 males over the age of 40 undergo male menopause, the degree and magnitude of which varies progressively over time.
Scientifically Backed & Internationally Patented
Our proprietary formulation is patented in Japan, China, and South Korea as an effective Testosterone Secretion Promoter. This international recognition guarantees top-tier quality, innovation, and trust for our global customers.
Tested 100 Selected Candidate Ingredients for Testosterone Secretion
Cell Culture(Culturing target cells for testing)⇒Screening with Candidate Ingredients(Stimulating cultured cells with 100 selected food-grade ingredients)⇒Testosterone Level Measurement(Quantified using the ELISA method)
Key Outcome / Result Text
As a result, we successfully identified multiple active components that stimulate testosterone secretion!
Introducing a New Functional Botanical Ingredient Combining 3 Active Extracts!
Steron Power Mix®
Key Active Components (3 Key Ingredients)
Delphinidin-3-rutinoside (from Blackcurrant / Cassis)
Rosmarinic Acid (from Red Perilla / Akajiso)
Inositol (from Rice Extract)
Key Features & Clinical Evidence (Points)
Joint R&D Project:
Co-developed with a Japanese National University over a period of more than 5 years by Japan Pharma Co.,Ltd.
Highly Safe & Familiar Food Ingredients:
Formulated using only well-established food-grade ingredients with a rich history of safe human consumption.
International Patent Protection:
Patented as a "Testosterone Secretion Promoter" in Japan, China, and South Korea.
Proven Human Clinical Trial Results:
Study Design: Human monitor study administering 200mg/day(n=13) and 600mg/day(n=12) over an 8-week period.
Outcome: Demonstrated significant improvement in AMS scores (Aging Males' Symptoms scale, a self-assessment metric for male menopause severity) along with positive qualitative user feedback.
Safety: No adverse events reported throughout the study.
Steron Power Mix® was found to possess PDE-5 inhibitory activity—the same active mechanism found in Erectile Dysfunction (ED) medications like Viagra.
Mechanism of ED Medications
Step 1: PDE-5 Inhibition⇒Step 2: Inhibition of cGMP Degradation⇒Step 3: Smooth Muscle Relaxation⇒Step 4: Increased Blood Flow⇒Outcome: Erection
PDE-5 inhibitory activity was measured for Fenugreek Seed Extract, Tongkat Ali, and Steron Power Mix® to calculate their IC50 values (the concentration required for 50% inhibition).
The results demonstrated the following order of PDE-5 inhibitory strength:
Steron Power Mix® ＝Fenugreek Seed Extract ＞＞ Tongkat Ali Extract
The vertical axis represents PDE-5 activity, and the horizontal axis shows the concentration of Steron Power Mix®.
As the concentration increases, PDE-5 activity is significantly suppressed.
Steron Power Mix® boosts male vitality through a unique mechanism distinct from direct testosterone secretion enhancement.
Steron Power Mix® is manufactured in a domestic GMP-certified facility in Japan.
