Product description:


Testosterone is a steroid hormone from the androgen group and is found in humans and other vertebrates. In humans and other mammals, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid.

In general, androgens promote protein synthesis and growth of those tissues with androgen receptors. Testosterone effects can be classified as virilizing and anabolic, though the distinction is somewhat artificial, as many of the effects can be considered both.

Product description:

Testosterone belongs to a class of hormones known as androgens; in-fact this is the primary androgenic hormone. A very powerful hormone in its own right, testosterone is largely responsible for testicular and prostate development, as well as the development of muscle tissue, bone density and strength. Beyond these basic functions, testosterone is by-in-large imperative for our overall general health and well-being; low levels of testosterone can not only negatively affect muscle and bone strength but can negatively affect our state of mind.

While a member of the androgenic class of steroidal hormones, testosterone is also highly anabolic. As both androgenic and anabolic, like all steroidal hormones testosterone is derived from cholesterol and is largely regulated in terms of production by luteinizing hormones (LH) and follicle stimulating hormones (FSH). Being regulated by LH and FSH, in order for these hormones to be released the pituitary gland must first be stimulated in order to achieve this purpose; once achieved and LH and FSH are released, testicular stimulation is achieved thereby causing the production of testosterone. As you can easily see, as important as the testicles are in testosterone production, the pituitary gland is of equal importance; without adequate pituitary function natural testosterone production cannot occur.

Fitness Tips~~

Spinning is one of the most popular sports in the gym!

The biggest feature of a spinning bike is that you feel that you can release the energy that has been stored for a long time, resulting in a sense of accomplishment. Not only can reduce fat, but also improve heart and lung function.

However, many people will fall into some misunderstandings when they are doing a spinning exercise! Especially girls!

Sense of cycling practice two misconceptions

Misconception 1: Will riding a bicycle become an elephant leg?

You can go to the spinning bike coaches who have many years of training experience. Their sturdy shape will tell you that you don't have to worry about spinning bikes to make you a "big Mac".

Many girls are particularly worried that cycling aerobics will thicken their legs. In fact, such fears are actually unnecessary. Continuous high frequency and low strength riding is impossible to reach the realm that makes your legs thicker!

Not every sport will make you muscular! The bodybuilder gets such muscles after hard training!

First, why do you think the bike legs will get thicker? Because you have been cheated!

1. An illusion, just an illusion

Some people feel that their legs are very tired when they are cycling. If they feel tight, they think that the legs are "long and thick". In fact, this is just an illusion, just an illusion.

Many girls think why they are going to ride their bicycles and have thick legs. I tell you that it is just that the legs are congested after exercise, which causes the muscles to swell and immediately reduces to the original state the next day. In essence, the muscles are almost non-growth (or a very small amount of growth...). It is recommended that you record your own circumference data. The tape measure will not lie!

2, the strength is wrong, aerobic exercise is not long muscle!

High-intensity and intense anaerobic exercise may cause the legs to grow muscles, which is the result of thick legs. The aerobic exercise consumes sugar, fat, and amino acids in the body, which only reduces excess fat. The sprinter’s calves are very sturdy. The marathon runners are very thin. Because most of them are aerobic exercise.

Muscle is not as long as you want, you can grow long (girls are born with less male hormones). 99% of girls think that they grow muscles, they are actually fat. Boys going to the gym will have to work hard for a year and a half to see the results!

Pay attention to cycling time and speed. Slow-paced aerobic exercise

The method of avoiding thickening of the legs should adopt low-intensity cycling under aerobic exercise (avoiding explosive sprint riding), characterized by low intensity, rhythm and long duration. Pay attention to time and speed when riding a bicycle. Generally, it takes at least 30 minutes for aerobic practice and no more than one hour. The speed should not be too fast, and the heart rate should be controlled within the heart rate of aerobic exercise, but it should not be too slow, otherwise it will not be able to exercise.

Aerobic heart rate: (220-years) × (60%-80%).

On the contrary: many people have become thinner after a period of cycling training! Because their overall fat percentage has dropped! Partially natural will be a small circle

Misconception 2: Is there more sweat, the more you can lose weight?

In fact, what needs to be reduced is fat, not moisture. The discharge of a lot of sweat is actually the loss of body water, and does not necessarily mean that body fat is consumed in large quantities.

Sweating is the way the body regulates body temperature! Although fat decomposition will produce some moisture but not much! The main factor that determines how much you sweat is the temperature around you! In the summer, standing still, sweating, vaginal and sweating, but it does not mean that you consume a lot of calories! The lack of sweat in winter fitness does not mean that you are not at work!
