What makes a man sick?

[Typical life of a Korean men]

Excessive works, unbalanced food intake and drinking alcohol destroy the health of modern men. Moreover the stress from each age group’s life style seeking happiness and pleasure destroys their health.

A typical example:
The heath of a man in his 30s

No effect without cause! – A man in his 30s is susceptible to sexual dysfunction, health problems and prostate problems!
The health of a man in his 30s is at stake. The National Health Insurance Corporation published 2010 Health Screening Statistics Year Book containing the major indicators for the health screening. According to that, men in their 30s shows the highest obesity rate (41.1%) and smoking rate(52.8 %).
Their health in their hey days is destroyed by their bad habits. As they grow old, they are more likely to have sexual dysfunction, prostatitis and prostatic hypertrophy, etc. So those in their 30s need to take special care of their health.

Many studies including this study have reported men in their 30s are getting sick. Last month, the Korea Centers for Disease Control and Prevention published the National Health and Nutrition Survey Report and it showed the similar results. In this report, the smoking rate of the men in their 30s was even higher, 54.8%; 1 of 4 men drinks Soju at least 2 times a week, more than 6 cups each time(high-risk drinker group); and 29.8% feel stressed, the highest of the all male age group

A typical example : The health of men after 40

Causes result in results- A pain of middle-aged men: Prostatic Hypertrophy, Sexual Dysfunction, etc.

Our fathers carry too much weight but do not show that. Incidence rate rapidly increases as they grow old.

Prostate produces various secretions to prevent the urethra from drying out and is closely related to male hormone Androgen. It grows in size as the secretion increases. The size of the prostate of men in their 20-30s remains unchanged till they are in their 50s, and then it grows in size. This is called Benign Prostate Hyperplasia. Hormone therapy can return the size to normal, but this therapy has the high-risk of adverse effect. If the hormone therapy is stopped, the size of prostate grow again.


Symptoms of benign prostatic hyperplasia-weak stream, residual urine, hesitancy, nocturia, even retention of urine.

Enlarged prostate oppresses the urethra that passes through the prostrate and narrows the urethra, resulting in urination related problems. In the early state of benign prostatic hyperplasia, residual urine is felt and urine tickles. It leads to weak stream, decreased amount of urine, frequent urination and nocturia. Since urine stays longer in the bladders, it may develop into acute cystitis, causing you to come to the emergency room.

<Problematic disease afflicting men>
What are the root causes for sexual dysfunction, prostate disorders, chronic fatigue, hangover, male hormone disorder and andropause?

What is testosterone?
It develops male secondary sexual characteristics, promotes spermatogenesis and grows prostate and seminal vesicles. Sex hormone, which is related to reproductive function, is secreted from the hypothalamus and produces luteinizing hormone. Luteinizing hormone travels along blood stream and stimulates Leydig''s cells in the testicles, forming male hormone testosterone. Testosterone is secreted into the blood vessels and flows into the muscles, thereby growing the muscle size.

Remove the waste accumulated in the urethra; Improve blood circulation;
Enhance metabolism and immune system

The first stage is for prostate and urethra. When a problem occurs in this parts, most men will feel pain and discomfort during their everyday life. The problem with this is that the waste increasingly accumulates with age, which leads to the blood circulation disorders.

Blood circulation disorders weaken the immune system and cause male sexual dysfunction including impotence and premature ejaculation. Blood supplies oxygen and nutrients to the respective cells of the body and removes the waste created by the cell via blood vessels .

The accumulated wastes in the blood vessel block the flow of blood, incurring myocardial infarction, hypertension, the hardening of the arteries and other cardiovascular diseases. To ensure smooth blood circulation, it is required to remove such wastes. However, the immunity of modern people declines due to stress, drinking and smoking, so it is hard to discharge wastes from the body. The deterioration of immunity promotes secretion of stress hormone Cortisol.

Fermented red ginseng, the main ingredient of Mensgear Stage 1, improves the immunity and enhances the blood circulation by way of inhibiting the blood coagulation, and expands the blood vessels, preventing wastes from accumulating. In addition, zinc promotes the normal male hormone secretion and helps produce healthy sperms. Besides, it contains natural substances improving sexual functions such as ginseng berries, adding to its efficacy.

Cortisol excites the sympathetic nerves, which in turn contracts the blood vessel, thereby inhibiting the process for discharging waste and detoxification. This inhibits the blood supply to the penis, which in turn result in sexual impotence. In order to improve the sexual dysfunction, it is critical to expand the blood vessels of prostate and urethra. Therefore it is critical to improve body's normal immune function, which can prevent the blood coagulation and the accumulation of waste in the blood vessels.

Erection stimulators, erectile dysfunction, sexual dysfunction, the increase of testosterone, The enhancement of exercise performance ability

According to the Korean Society of Sexual Medicine and Andropology, 28.4% of Korean men suffer andropause. Its typical symptoms include chronical fatigue, loss of work efficiency, impotence and sexual dysfunction. Andropause is caused by the increase of sex hormone(testosterone)-binding protein and the decrease of testosterone.

Some men start suffering andropause from in their early 40s if testosterone decreases. Its typical symptoms include chronical fatigue, decrease of stamina, loss of work efficiency and sexual dysfunction such as impotence, reduced sperms and decreased sexual pleasure.

Andropause also affects men’s social status adversely while decreasing their work efficiency. Thus quick improvement is required. Menzgear Stage 2 contains vitamin B, oktakosanol and zinc. Vitamin B is various soluble vitamin complex, controlling the cellular metabolism.
The vitamin is effective in preventing fatigue and the recovery from fatigue while engaging in the formation of antibodies, thereby promoting energy conversion and enhancing immunity. Oktakosanol components have the ability to seamlessly convert the glycogen stored in the muscles and liver into energy, thereby increasing men’s stamina.
In addition, the zinc contained in Menzgear Stage 2, promote testosterone secretion. Testosterone produces nitric oxide which expands and contracts the blood vessels, inhibits the reaction of aromatase enzyme and reduces the conversion from testosterone to estrogen, thereby helping improve the andropause. This means the expansion of blood vessels as well as the improvement of blood vessels.

According to the results of a survey with 1000 Korean adults in 20s-50s, 38% of the respondents answered they has less than one sexual intercourse with their spouses a month, indicating 4 of 10 adults are in the potential sexless state. With regards to the reasons, they suspected excessive work load and chronic fatigue. Particularly, the chronic fatigue is caused by fatigue liver.
Fatigue in general is defined as abnormal exhaustion, a state in which a person cannot continue to make an effort or concentrate because of exhaustion or a state in which a person is out of energy so cannot engage in normal daily activities. If this fatigue lasts more than 1 month, it is called prolonged fatigue, and if it lasts more than 6 months, it is called chronic fatigue.
Unlike transient fatigue, chronic fatigue cannot be recovered after a few moments of relaxation, is very debilitating.
Most of Korean men have their livers damaged by drinking, smoking and stress. Liver dysfunction causes physical fatigue to accumulate fatigue and hinders the male hormone metabolism, which in turn leads to sexless life. Menzgear Stage 3 was made after constant trial and errors to solve the problems arising from such men’s lifestyle.
3-Stage multi-vitamin and mineral contents help our bodies absorb nutrients and promote metabolism, which protects our livers. Healthy livers convert ammonia into urea by way of the metabolism of carbohydrates, proteins, nucleic acids and alcohol, and produce bile. The bile produced in the liver absorbs fat, maintains the equilibrium of cholesterol and discharges body wastes, thereby improving physical fatigue and our married life.

3-month clinical effects for 300 men in their 40s~70s treated with Menzgear

RNC Bio has treated 300 men in their 40s~70s with menzgear Stage 1, 2 and 3 for 3 months. The results showed positive effects in 4 categories: testosterone, erection stimulators, sperm count and endurance exercise performance ability. In particular, 37% of participants showed significant expansion of the blood vessels in the prostate and urethra and the increase of testosterone, thereby increasing the amount of semen prolonging penile erection. In addition, their frequent urination and residual urine were also improved.
