Pre-Workout Supplement Advice


Testosterone is a sex hormone that regulates a man’s:
• sex drive (libido)
• bone mass
• fat distribution
• muscle mass
• strength
• red blood cells
• sperm production

Investigators discovered that a small amount of testosterone within man’s body is converted to estradiol, a form of estrogen. Hence, as a man ages, he makes less testosterone; concomitantly, he produces less estradiol. Thus, changes attributed to testosterone deficiency are partly or due to the accompanying decline in estradiol.

One study found that normal testosterone levels range from between 264 and 916 nanograms per deciliters (ng/dL). This was determined by studying 9,054 men aged between 19 and 39 who had a healthy weight. The Food and Drug Administration had pegged the normal range as between 300 to 1,000 ng/dL. The American Urological Association says about 2 out of 10 men older than 60 years have low testosterone levels. That range increases to 3 out of 10 men in their 70s and 80s. Aging decreases the testosterone level by 1 to 2 percent per year. Those vulnerable to low testosterone level are:

• Men whose testicles were removed, damaged by accident, or naturally are malfunctioning.
• Men undergoing Chemotherapy or radiation treatment.
• Victims of pituitary gland disease leading to hormone deficiency.
• Patients of autoimmune disease (when the body makes antibodies that attack its own cells)
• Metabolic syndrome sufferers (high blood pressure, high blood sugar, unhealthy cholesterol levels, and belly fat).
• Users of psychotropics (antipsychotics and narcotic pain medications.
• HIV patients(about 30 out of 100 have low testosterone).
• AIDS victims(about 50 out of 100 have low testosterone).


If you happen to be among those vulnerable to Testosterone decline, observe if you are experiencing the signs and symptoms. The two types of signs and symptoms are:

1. Specific:
• Reduced sex drive
• Erectile dysfunction
• Loss of body hair
• Less beard growth
• Loss of lean muscle mass
• Constant feeling of tiredness or fatigue
• Obesity (being overweight)
• Symptoms of depression

2. Non-specific:
• Low energy level, endurance, and physical strength
• Poor memory
• Poor focus

To be sure if you have a testosterone deficiency, consult a doctor. By measuring the quantity of testosterone in your blood, a doctor can determine whether your testosterone level is within the normal range.


If you’re experiencing one or multiple signs of declining testosterone levels, clinicians advise you to adopt the following testosterone-boosting lifestyle habits:

1. Get sufficient sleep.
The University of Chicago found that testosterone levels drop in men who do not sufficiently sleep. The researchers found that after 1 week of restricted sleep, their subjects’ daytime testosterone levels dropped by up to 15 percent.

2. Maintain a balanced diet.
The Journal of Neuroinflammation revealed that overeating and yo-yo dieting disrupts hormone levels, including testosterone. This was observed among athletes and active people.

3. Maintain a healthy weight.
One study published in the journal Clinical Endocrinology reported that obese males between the ages of 14 and 20 have up to 50 percent lesser testosterone than those who are not overweight.

4. Stay normally active.
A study in the European Journal of Applied Physiology found that the testosterone levels of active individuals increased as they become more active.

5. Avoid getting excessively stress.
While taking their final exams, 58 male and female medical students provided researchers with saliva samples. The men showed significant increases in salivary testosterone because of taking a difficult final examination.

6. Take appropriate Vitamins and Testosterone Boosting Supplement.
• The journal of Hormone and Metabolic Research found that taking vitamin increases testosterone levels.
• A study provided DHEA supplements to a group of older men. The researchers found that the supplements produced small but significant positive effects.
• Biological Trace Element Researchers found that taking supplements for at least 1 month increased testosterone in all participants.
• A 2007 study showed 4 weeks of zinc supplementation could prevent a decline in testosterone levels in sedentary men who did exercises.
• A 2006 research found higher levels of testosterone in college football players after taking creatine supplements for at least 10 weeks.


However, not every testosterone boosting supplement contains ingredients that work. Here are clinically proven ingredients:

D-Aspartic Acid signals the brain to release a luteinizing hormone that triggers testosterone secretion. In addition, it stimulates hormones that help your muscles to grow.

Ginseng stimulates the discharge of Nitric Oxide. It signals the Luteinizing hormone to secrete Testosterone.

Bioperine increases the efficacy and availability of hormone-boosting ingredients into the bloodstream.

Boron improves your bone health and helps in muscle growth. Boron helps decrease estrogen in your blood.

Oyster Extract is rich in Zinc, the essential element of Testosterone production. Besides, it contains Vitamin, Amino Acids, and Omega 3 fatty acids.

Fenugreek is for males who couldn’t grow muscle mass or are less virile. It’s a herb that maintains the level of Testosterone throughout the daytime.

Nettle extract inhibits the binding of Testosterone with Globulin, which increases free Testosterone. This reduces the rate of estrogen conversion.

It signals the brain to release follicle-stimulating hormone and luteinizing hormone which produces Testosterone.

The latest researches suggest that testosterone boosters that contain the said ingredients are the supplements that work. Hence, they are the most patronized and high ranking testosterone booster in the market.

Based on the data above, you can draw the following conclusions:

1. Testosterone is a male hormone. A small amount of testosterone within man’s body is converted to estradiol, a form of estrogen; estrogen is the primary female hormone. As a man ages, he makes less testosterone; concomitantly, he produces less estradiol. Thus, testosterone deficiency is partly attributed to the accompanying decline in estradiol. This theory is the basis for the inclusion of estrogen-suppressing elements in testosterone boosters.

2. There are clinically proven testosterone-boosting ingredients. However, not all boosters containing these ingredients work. This happens because the ingredients need to be used in accordance with prescribed consistency; producers don’t uniformly follow prescriptions. Moreover, users are required to take the supplements in accordance with working doses and frequency; not all users follow prescriptions.

3. Not all testosterone boosters are dedicated to solely enhancing testosterone levels. There are substances that indirectly boost testosterone by promoting weight loss, fat burning, muscle mass production. Hence, though not promoted as testosterone boosters, supplements for fat burning, muscle development, weight loss, and general wellbeing are good as testosterone boosters; however, the use of non-specific testosterone supplement is best advised by a doctor.
