Review Criteria
Safe Effective Herbal Ingredients
We only included ingredients in our review
where we found multiple scientific studies vs. anecdotal evidence that support
it's positive effect on the various functions that are important to produce
a strong full erection, increase libido and treat impotence issues. This is not to say that other
herbs
are not effect, only that we have scientific research backing the ones
listed.
Shilajit (Viagra effect)
The anti-stress and adjuvant effects have
been
evaluated in a number of India studies. Shilajit is found to provide an anti-oxidant
defense against several reactive oxygen types. Processed Shilajit provided
complete protection to methacrylate against hydroxyl radical induced
polymerization and acted as a reversible nitric oxide-captodative agent.
These findings are consistent with the therapeutic uses of Shilajit as an
Ayurvedic (rejuvenator) against oxidative stress and geriatric complaints
of erectile dysfunction.
Horny Goat Weed (Viagra effect)
Horny goat weed
has been used for for over 2000 years as an sexual and reproductive tonic.
It's acts in multiple ways to increase erection ability, size, and fullness.
Horny goat
weed contains a prominent flavonoid called icariin.
Icariin is a cGMP-specific PDE5 inhibitor like Viagra, Cialis and Levitra.
This was demonstrated in a 1984 University of Peking study.
Also it
functions like an adaptogen by increasing levels of epinephrine,
norepinephrine, serotonin, and dopamine when they are low - promoting
energy, but reduces cortisol levels when they are elevated (an
anti-stress effect). High stress conditions, increase cortisol levels
causing fatigue and depressing sex drive.
Finally,
horny goat weed
can restore low levels of both testosterone and thyroid hormone back to
normal - improving sex drive.
L-Arginine (Viagra effect)
L-arginine is an amino acid present in all life
forms.
Typical food sources include meat, nuts,
eggs, milk, & cheese.
Arginine a required building block to enable the synthesis of nitric
oxide, which relaxes blood vessels and allows more blood to flow
through arteries to the penis. If your body is low on Arginine then
Nitric Oxide creation can suffer reducing penile blood flow. L-arginine
insures that your body has this critical amino acid
required to have strong erections.
In fact, research has shown that
the effect of Viagra is increased when combined with L-arginine.
L-arginine also increases sperm
count and motility. In one study sperm count was increased in 62% of
the men taking L-arginine. Other benefits of L-arginine include
improving the cardiovascular function and hypertension.
Allium Sativum - Garlic (Viagra effect)
Yes, Good old garlic. In two different 1998
studies one from the National University of Mexico and another from the Institute of
Pharmacology, Toxicology and Pharmacy, Munich, Germany show garlic to
"activate nitric oxide synthase" or enhance the nervous systems
ability to react to nitric oxide.
Also there are multiple studies compiled at
the Sloan-Kettering Cancer Institute which demonstrate Garlic’s assistance
in both preventing and having curative effects on several medical conditions which
are often the cause of ED. These include high blood pressure, heart disease,
hypertension and atherosclerosis.
Mucuna Pruriens
Mucuna Pruriens works as a prolactin
inhibitor, a growth hormone stimulant and to increase testosterone.
A U.S. patent was filed in 2002 on the use of
mucuna pruriens to stimulate the release of growth hormone in humans. The
high levels of l-dopa in the mucuna seed are converted to dopamine which
stimulates the release of growth hormone by the pituitary gland. L-dopa and
dopamine are effective prolactin inhibitors
Increased levels of prolactin are considered
responsible for 70% of erection failure in males. In one study, oral intake
of the seeds in 56 human males was able to improve erection, duration of
coitus, and post-coital satisfaction after only four weeks of treatment. It
also has alsopromots spermatogenic effects in men, improving
sperm count and motility.
Tribulus Terrestris
Tribulus is a natural testosterone
enhancer. It is also said to be an excellent circulatory system tonic and can
help build muscles and strength.
Clinical studies on the sexual activity-enhancing effect
of tribulus have shown the herb
to contain protodioscin, a saponin constituent, improving libido
in men with impotence due to various causes; libido in women with menopausal
symptoms; and sperm motility in infertile and subfertile men.
In another study involving 59 men, ages
22-67, suffering from a range of sexual dysfunctions. An increase of sexual
desire and fantasies, as well as sexual self-confidence, were reported in
almost all of the patients. The subjective experience of pleasure, joy and
satisfaction was reported in 80% of the men; erection improved in over 75%
of the men; and the duration of intercourse before ejaculation was
prolonged in 25% of the men.
T ongkat
Ali (Eurycoma longfolia)
The root (long jack root) of the Eurycoma
longifolia tree has been used for centuries in Malaysia as a traditional
remedy for fatigue, loss of sexual desire, and impotence.
This amazing plant has only recently been recognized in the west for
it's potency helping sexual performance issues.
The bioactive Glygopeptide compounds
in Tongkat ali were shown to increase free testosterone and decrease
SHBG levels in human clinical trials. Both effects assist a mans
erection ability, performance and sex drive.
In the study by Ismail Tamby, MD,
head of the Human Reproductive Specialist Center in Kuala Lumpur,
90% of the
men given Tongkat ali extract reported a boost in their libido and
73.3% reported improved sexual function.
As an added benefit Tongkat Ali contains superoxide dimutase, a
powerful anti-oxidant enzyme that inhibits
the chain reaction of free radicals harmful to the body.
Ashwagandha
Here is what the Sloan-Kettering Cancer
Center had to say in their Ashwagandha Clinical Summary.
"It (Ashwagandha) is also used as a general
tonic, to increase energy and improve health and longevity...
Ashwagandha has been shown to exhibit antioxidant effects in the brain and
to have a tranquilizing effect on the central nervous system in animals...
Human study's suggest Ashwagandha may promote growth in children and improve
hemoglobin concentration, red blood cell count and sexual performance in
adults."
Contains Non-Herbal Ingredients
Zenerx does not contain other additives.
Enzyte contains the following other
ingredients: Dicalcium phosphate, stearic acid,
croscarmellose sodium, magnesium stearate, silica and film coat (hypromellose,
hydroxypropyl cellulose, polyethylene glycol, titanium dioxide, propylene
glycol, and FD&C blue #2 lake).
Herbal Ingredients That Support Overall Male Health
and Prevent/Help ED Causing Conditions
There are multiple causes of weak & small
erections, impotence and low sex drive which may range from mild (low sex drive, weak
erections, lack of energy, slow and weak ejaculation) to severe (total
inability to achieve erection and complete lack of sexual desire).
These include:
- Cardiovascular (i.e.
restricted blood flow, high blood pressure, heart disease, hypertension and
atherosclerosis)
- Renal or urological
- Nutritional
(i.e. malnutrition, vitamin or mineral deficiency)
- Endocrine (i.e. low testosterone or high prolactin)
- Neurological
- Muscular & Tissue
- Psychological (i.e. stress,
anxiety, etc.)
By increasing your health in the above areas
you are often able resolve sexual dysfunction issues. This is perhaps where
the greatest benefit that natural herbal supplements provide to a mans total
sexual performance.
Minimal -
Ingredients provide primarily support for an erection, but limited benefits
in other important areas.
Moderate - Ingredients provide some
additional benefits to the other ED related conditions and overall health.
Significant
- Ingredients provide significant preventative/help benefits for other ED causing
conditions and overall male health.
Potentially Dangerous Ingredients
We reviewed the ingredients in each of the supplements and
cross checked the ingredients against ingredients identified by the FDA as
"Supplement Ingredients With Concerns" The one common ingredient
on this list is
Yohimbe it is considered dangerous and it is an ingredient in a number
of male enhancement/impotence products on the market.
Our recommendation is to avoid any product containing
Yohimbe. There are many other alternative ingredients that have proven
effective and are safe.
Neither Enzyte nor Zenerx contain Yohimbe
or any other FDA "Supplement
Ingredients With Concerns"
While the ingredients contained in both
supplements are considered safe individuals may have different
reactions to the ingredients just like with food.
Other Factors
Product Guarantee
It is important that any manufacturer stand
behind their product with a money back guarantee. The fact is, each individual
is different. Some formulations may work better than others for an
individual their condition that may be cause impotence, small or weak
erections. That's why a 100% guarantee is a must and the manufacturer must
follows through with the guarantee.
According to
consumer groups and the Better Business Bureau, Berkeley (maker of Enzyte) generates a high number
(3522) of complaints .
|
(1) "Enzyte used deceptive
practices to prevent customers from receiving ‘double your money back’
refunds"
A lawsuit has been filed on behalf of
purchasers of the herbal male enhancement supplement Enzyte,
claiming the manufacturer Berkeley Premium Nutraceuticals (Berkeley)
knowingly used false and unproven claims to lure men into purchasing the
supplement, and used deceptive practices to prevent customers from
receiving ‘double your money back’ refunds.
The suit alleges that Berkeley, which is currently
running a national ad campaign featuring innuendos and a silent 'Smiling
Bob' character, claimed that Enzyte would add one to three inches to a
man’s penis size or customers would get double their money back, among
other claims.
Customers trying to collect on Enzyte’s guarantee
received deceptive attempts to coerce them into giving up their right to
receive a refund, and ultimately did not receive twice the purchase amount
as promised, according to the complaint. |
Made in The US
By purchasing only from companies that only
manufacture their product in the US you can help insure that the ingredients are as
labeled. Most of the supplements that have had other substances added (such
as sildenafil citrate) have been manufactured outside of the US by
unscrupulous companies.
Check to make sure that the supplement is manufactured in
the US and not just a US company that imports their product from abroad.
The Vinarol recall is a recent example of this occurring.
Known FDA Complaints or Recall for the Specific Product
We checked to see if there are any known
product complaints or
recalls registered with the FDA for each of the products reviewed.
Known Better Business Bureau Complaints
We check with the Better Business to
determine if there are any complaints and the resolution of the complaints.
Enzyte has a lengthy history and pattern of
unsatisfactory business practices see the BBB report below. Claims filed
3522, 1421 satisfactorily resolved.

Zenerx did not have any claims filed with the BBB
Potential Misleading Claims
Because we do expect companies to shine a
positive light on their product, we try to give they the benefit of the doubt on
subjective information. Because every individual is different results of any
herbal supplement or pharmaceutical will vary. That's why in our review we
focus on the proven ingredients. However if a claim is made that is clearly mis-leading
based on other factual evidence it is graded as a potentially mis-leading
statement.
Based on the above facts Enzyte was found to
have potentially mis-leading claims regarding their guarantee and the use of
deceptive practices.
We did not find any with Zenerx.
Recommendations
While all both products include a variety of ingredients
that have been shown to be effective to increase erection ability, size,
firmness and help impotence, we cannot recommend Enzyte because they do not
honor their guarantee by refunding customers money.
In this review, we only recommend Zenerx.
Enzyte: Not Recommended
