All the old jokes about being able to "bottle" sex appeal turn out to have a basis in reality. Recently scientists discovered how to isolate and concentrate the chemical-hormonal substances -- called pheromones -- that create sexual attraction in humans. It's now possible to wear pheromones and put out their invisible sexy signals at will.

The effect of pheromones has been very well studied. They cause an instinctual, almost automatic sexual response, which scientists call a "releaser" effect. Each person has a unique "odor print" that's just as individual as fingerprints, created by compounds released from the sebaceous glands, sweat glands and other glands. Among the chemicals and compounds released are pheromones, which drift into our companion's nasal passage and stimulate specialized receptors. Scientists are still studying the receptors to determine whether the "vomeronasal organ" is devoted to exclusively to sensing pheromones, or whether pheromone receptors are part of a more complex system along with olfactory receptors in the nasal passage.

The two compounds that are most widely recognized as pheromones are androstadienone (AND) and estratetraenol (EST). AND is a derivative of testosterone and EST is a relative of estrogen. Scientists have shown that the chemicals change brain patterns as detected by EEGs, functional MRIs, and PET scans, and induce mood changes. That evidence is consistent with what pheromones would do.

Synthesized versions of these compounds can be even more potent and effective than one's natural "odor print" mainly because Americans do so much to obliterate any trace of natural odor and sweat. In today's society, our showering, deodorizing, cologne-applying and almost sterile approach to cleanliness keep our natural pheromones from doing their job.

That's why the idea of concentrated pheromones makes so much sense. The trick is finding a good source of genuine pheromones, not just diluted or even fake preparations making claims. There are a few good products out there that actually are what they say and have an excellent reputation for creating more arousal, more interest, more attraction and more willingness in the opposite sex. One we recommend is Nexus Pheromones™, made from 100% genuine human pheromone. If you're shopping around, insist on a money-back guarantee and note whether the product is pure concentrate vs. a cologne or alcohol preparation that simply contains some tiny proportion of hormone.

New transdermal technologies have made it possible to encapsulate active, herbal ingredients into an oil that you can apply right to the source of the action -- so they take effect immediately. You just massage a little oil onto your penis, and let the games begin.

Too good to be true? Nope. Transdermal oils really do work, and their application as an erection and sexual stamina enhancer is like a match made in heaven.

Here's how it works: ideally, the oil is silky, condom-compatible (aka: water based), and non-greasy. It provides naturally occurring nutrients and herbal extracts directly to the male organ via a breakthrough method - known as the transdermal method, or in some products like VigRX Oil™, the German Transdermal Delivery system. This is the latest scientific development in beneficial nutrient absorption through the skin, so the naturally-derived therapeutic ingredients, botanical extracts, vitamin complexes and antioxidants go straight into the tissues of the penis - fast, targeted specifically, and immediately effective.

Good-quality oils in this category should produce greater penile firmness, an increase in penile tissue engorgement, a longer-lasting erection, and a far reduced occurrence of premature ejaculation.

So how are these oils different from an oral tablet for male enhancement? Enhancement oils are designed to penetrate the deepest layers of the penile tissue and testicles instantaneously, and give noticeable results within 30 - 90 seconds. Because the absorption is direct to the genitals using the transdermal method, 95% of the beneficial ingredients are absorbed, compared to approx 5 to 10% with an herbal capsule or tablet. The other benefit: it lets you be ready for anything! The last-minute nature of this product means you can use it right when you need it with nothing else to remember or take.

Male enhancement oils are part of the next generation of sexual products, and are revolutionizing the industry with their effectiveness. Although commonly referred to as oils, many of these products are water-based. If you are going to be using your “oil” with condoms, make sure the formula you select is water based as oil based formulas reduce the effectiveness of latex. If you are unsure which products are safe with condoms, we suggest you try VigRX Oil™.

The ingredients vary widely by manufacturer, but may include variety of natural herbal remedies, vitamins, amino acids and flavoring. One of the main ingredients in assisting with the sexual boost is L-Argynine, an amino acid which converts to nitric oxide, a fundamental building block to the cycle of orgasm in men. Two other good indicators of quality are the method of manufacture and the longevity of the maker, that is, how long they've been in business.

Human growth hormone, also called somatotropin, is a protein hormone of 190 amino acids (building blocks of protein) that is created and secreted by the anterior pituitary gland. It has two types of effects, both of which are highly beneficial to the vital, active human body.

One main type of action of the HGH is its direct effects on other kinds of cells. The growth hormone binds to its receptor on target cells, then creates some particular action. Fat cells, for example, are the target cells of HGH, so they have growth hormone receptors. Once bonded there, the growth hormone causes them to break down triglyceride and suppresses their ability to take up and accumulate circulating lipids -- in other words, fat storage is prevented!

HGH also acts to create other indirect effects in the body by causing secretion of IGF-1, an insulin-like growth factor hormone. IGF-1 is secreted from the liver and other tissues in response to growth hormone. This is the action that governs mostly growth-related effects of HGH.

This same effect is also the power behind muscle growth. It stimulates both the differentiation and proliferation of muscle cells, stimulates amino acid uptake and synthesizes protein in muscle and other tissues. This is where HGH's ability to influence overall muscle and skin tone comes from.

Growth hormone has important effects on:

• Protein metabolism:
  HGH causes increased amino acid uptake, increased protein synthesis and decreased oxidation of proteins.
  
  
• Fat metabolism:
  HGH enhances the utilization of fat -- gives your body the ability to break down fat cells more efficiently.
  
  
• Carbohydrate metabolism:
  HGH is one of several hormones that maintain blood sugar within a normal range.

Because of the abilities of HGH mentioned above, you can soon see that without it, muscle tone declines, fat stubbornly sits in the body and resists metabolism, and hair, skin and nails (all composed of proteins) deteriorate. In fact, scientists now believe that HGH has a role in most healthy functions of the body, including sexual function, proper operation of stomach and bowels, liver, and all glandular systems.

Whether HGH is directly interacting with certain cells, or playing its key part in the correct function of other bodily systems, it's essential throughout the body for youthful vigor and health.

Problem is, HGH augmentation has traditionally been a benefit reserved for the super-rich: until now, only injections of HGH could have an effect in the body, and at a cost of thousands of dollars per treatment.

More recently, pharmaceutical companies and natural supplement companies have fine-tuned the science of HGH stimulation in the body by means of a Growth Hormone releaser. That is, by natural means, the body can be stimulated to produce and release its own HGH, increasing levels to those of a youthful, vital person.

One such supplement is GenF20™, a supplement from a quality manufacturer. Their product works by using a formula to trigger and stimulate the pituitary gland to produce and secrete more HGH itself. The HGH goes into your body just as nature intended, in other words, through the glandular system -- just as it did when you were in your 20s. You see, it is not possible to just make an HGH supplement that would enter the bloodstream by other means than injection, because the HGH molecule is too large to pass through the walls of the digestive system, for instance. But with a "releaser" or stimulator product, your body does the HGH producing itself.
