To maximize efficacy, you should consume this stack in a fasted or semi-fasted state and at least 6 hours before bedtime. This stack is going to significantly increase your heart rate and blood pressure so be watch out for overexertion if you choose to take the ECY stack immediately before an intense weightlifting session. Some users also choose to alternate consuming EC and EY to obtain some of the positive effects without being overstimulated.
3. Men With Bad Lipid Readings.  One study examined men with both erectile dysfunction and "dyslipidemia."  Dyslipidemia is medical speak for bad HDL, LDL, triglyceride or some combination of the three.  They gave these men 1.5 grams of niacin, which is a megadosed amount, and is a favorite of Dr. Davis.  (See my  Review of Track Your Plaque for Dr. Davis' approach to plaque regression.) Besides the above listed benefits, niacin will also a) lower triglycerides, b) boost HDL, c) increase particle size and d) decrease LDL particle counts.  All of these are very anti-atherosclerosis and great for your arteries. 
According to a study conducted by the University of the West of England, Bristol, pelvic floor exercises may be very effective in treating erectile problems. Many participants of the study, all of whom were men who had been experiencing erectile dysfunction for at least six months, reported a significant improvement of their condition within three months of training their pelvic floor. 
DHEA. DHEA, or dehydroepiandrosterone, is a natural hormone that the body uses to make the male hormone testosterone. DHEA and testosterone decrease with age, just as ED increases with age, so it seems that taking DHEA might protect against ED. But Harris says that "it is unlikely that taking DHEA would raise your testosterone enough to make much difference." DHEA should not be used by people with liver problems; it also has many side effects.

In addition to male sexual health, zinc is needed for burn and wound healing, proper digestion and utilization of carbohydrate foods, including: fruits, grains, sweets and vegetables as well as protein foods like beans, eggs, tofu or meat. Zinc is also necessary for the body to manufacture at least 200 different enzymes needed for various aspects of metabolism and life. Our blood, bones, brain, heart, liver and muscles require adequate amounts of this essential mineral to function properly.

In the 1700s, pellagra was an endemic disease in northern Italy—which had not been known until maize (corn) was introduced from America. Italy gave the disease the name, “pelle agra” (pelle means skin; agra means rough). Casal had observed that patients with pellagra were all poor, subsisted mainly on maize, and rarely ate fresh meat. Because pellagra outbreaks occurred in regions of Europe where maize was a dominant food crop, the belief was that maize either carried a toxic substance or was a carrier of disease. When it was later noted that there were few pellagra outbreaks in Mesoamerica, where maize is a major food crop (and is processed), it was considered that the causes of pellagra may be due to factors other than toxins.
The positive response in our patients was enhanced with the higher dose of yohimbine, a phenomenon noted previously.20,21 We agree that several weeks of therapy are needed before clinical effects are seen,21,22 and that some responders may be able to take yohimbine only on demand before sexual activity.39 Yohimbine is effective in a subset of men with organic erectile dysfunction, especially nonsmokers, and it deserves a place in our therapeutic armamentarium. When yohimbine is ineffective alone, it may be useful in combination with other treatment modalities, as has been shown with naloxone39 or trazodone.40
Responders tended to have consistently higher scores compared with nonresponders. For nonresponders, none of the scores was significantly different when comparing baseline scores with either of the yohimbine doses. However, a trend toward an improved total questionnaire score was noted from baseline to the 5.4 mg tid dose (P=0.083). For responders, a significant increase in the Florida Sexual History Questionnaire total score was observed from baseline to the time the 5.4-mg tid dose was administered (P=0.021). A trend closely approaching statistical significance (P=0.055) was noted from baseline to the administration of the 10.8 mg tid dose of yohimbine. Inspection of changes in the individual items revealed that responders reported significantly greater frequency of vaginal penetration with both the 5.4- and 10.8-mg doses of yohimbine tid compared with baseline (P=0.010 and P=0.010, respectively). Participants also noted less difficulty obtaining an erection for sexual intercourse while taking 10.8 mg of the drug compared with baseline (P=0.011). Responders reported having significantly less difficulty maintaining an erection for sexual intercourse compared with baseline with both the 5.4-mg tid dose (P=0.049) and the 10.8-mg tid dose (P<0.001). Responders also reported significantly greater penile firmness and rigidity before intercourse or masturbation in both treatment conditions compared with baseline (P=0.02 for the 5.4-mg tid dose and P=0.013 for the 10.8-mg tid dose).
Just because a product claims to be natural doesn't mean it's safe. Many herbal remedies and dietary supplements can cause side effects and dangerous interactions when taken with certain medications. Talk to your doctor before you try an alternative treatment for erectile dysfunction — especially if you're taking medications or you have a chronic health problem such as heart disease or diabetes.
Men, aged 40–80 y, were recruited from new consultations seen for erectile dysfunction at the Lahey Clinic Center for Sexual Function. Patients were screened by history and physical examination and by evaluation of nocturnal penile tumescence and rigidity with the RigiScan™ (Timm Medical Technologies, Inc., Minneapolis, USA). Candidates completed a sexual questionnaire and had morning blood tests for luteinizing hormone (LH), free testosterone, cortisol, dehydroepiandrosterone sulfate and androstenedione. Inclusion criteria included normal initial serum testosterone and prolactin levels and the presence of an organic cause of erectile dysfunction manifested by abnormal nocturnal tumescence and rigidity testing with the RigiScan™ monitor. Active smokers and men with concurrent major psychiatric problems were excluded. No other treatment for erectile dysfunction was permitted during the study. Yohimbine hydrochloride (supplied by Palisades Pharmaceuticals, Palisades, NJ, USA) was started at a dose of 5.4 mg three times a day (tid) for 4 weeks, after which the sex questionnaire was administered again and blood tests, nocturnal penile tumescence and rigidity testing were repeated. The dose of yohimbine then was increased to 10.8 mg tid for 4 additional weeks followed by a third administration of the sex questionnaire and final measurements of hormone levels and nocturnal penile tumescence and rigidity monitoring.
Selenium, found in Brazil nuts, liver and oysters, is a trace mineral that plays an important role in hormone health. You only need a tiny bit for healthy sperm, but a tiny deficiency can be catastrophic for reproductive health. In one study, men who had lower testosterone and were infertile also had significantly lower selenium levels than the fertile group. Supplementing with the mineral improved chances of successful conception by 56 percent. And a second British Journal of Urology study that included 69 infertile men with low levels of the mineral, found selenium supplementation could significantly improve sub-par sperm motility associated with testosterone deficiency.

Besides that, dyslipidemia (and hypercholesterolemia in particular), remain undertreated in many patients diagnosed with coronary artery disease. High triglycerides, a contributor to cardiovascular dysfunction by many but not all studies, are somewhat treatable with fibrates, yet there are significant limitations for their use. Elevated fasting triglyceride levels have been shown to be a strong risk factor for ischemic heart disease, independent of other known risk factors for atherosclerosis.
But you really do not need any medications like I-Arginine and others to solve your erection problems. Many researches suggest that if you try natural solutions and home remedies rather than going for medications, you will have a healthy and satisfying sex. These vitamins and supplements with surely  help in treating  your ED (erectile dysfunction) and other penis related problems.
ICI therapy often produces a reliable erection, which comes down after 20-30 minutes or with climax. Since the ICI erection is not regulated by your penile nerves, you should not be surprised if the erection lasts after orgasm. The most common side effect of ICI therapy is a prolonged erection. Prolonged erections (>1 hour) can be reversed by a second injection (antidote) in the office.

I am so grateful Jacqui, I am seeing my girlfriend tomorrow and feel like the problem is pretty much gone! I can't believe it I thought I was broken!!! I have searched on sooo many sites and got so much bad advice and feel like posting the link of your site on all of those others. As this is a horrible problem and your method will work for me - so guys need to know this! Many, many thanks for the help.
In male rats, main olfactory epithelium (MOE) exerts an important role in regulating sexual behavior. Intranasal irrigation with zinc sulphate has been reported to destroy the MOE and completely abolish the sex behavior.[6] In this study supplementation of zinc was done using a feeding tube and precautions were taken to avoid contacting nasal area. Hence the possibility of reducing sexual performance due to MOE disturbance is ruled out. Some humans experience gastrointestinal irritation with supplementation of zinc.[23] If the same is applicable to animals it may be another possible explanation for the reduction of libido index with elevated doses of zinc. One drawback of our study is that we did not compare the weight of animals before and after treatment.
Exercise helps to maintain blood circulation to this region and strengthens your heart so it can pump blood more effectively when at rest. As you exercise, your blood vessels dilate and more capillaries open so that blood can effectively be moved to where it is needed. Much of this blood is routed via the genital region, opening the network of vessels which feed the penis. The region will receive an improved circulation as a result even when your body is at rest, and increased blood flow to the skin itself brings the added benefit of greater sensitivity.
A study published in The American Journal of Cardiology confirmed that aerobic exercises will help you to cure your erectile dysfunction. Erectile dysfunction is most commonly caused by obesity, hypertension, and diabetes, which decrease the blood flow in the penis. Aerobic exercises can and will help you to improve your health in general, improve your blood flow, and ultimately treat your condition.
There was a higher incidence of adverse events in those taking niacin. However, most patients could tolerate it at the maximum dosage (1,500 mg/day). With this in mind, niacin could be an alternative choice of treatment for patients with ED. Despite the success of phosphodiesterase type 5 inhibitors (PDE5 inhibitors), such as sildenafil, only around 60–70% of patients have a satisfactory response to this class of drugs. And there are adverse effects such as headache, flushing, dyspepsia, nasal congestion, and impaired vision, including photophobia and blurred vision. Hence, there is a need to develop other therapeutic agents for those patients who do not respond satisfactorily to PDE5 inhibitors or are contraindicated for those such as sildenafil.
Yohimbe is commonly taken to increase sexual excitement and to reduce sexual problems such as symptoms of erectile dysfunction (ED), also called impotence. Research shows that yohimbe may be capable of increasing blood flow to the penis or vagina. It also increases nerve impulses that play a role in orgasm. Due to how yohimbine affects blood vessels, it can cause relaxation of the penile tissue and engorgement of blood. This helps a man to maintain an erection. These effects are beneficial for both sexes when it comes to experiencing sexual satisfaction.

Also to be considered, patients were not using PDE5 inhibitors during the study period. Therefore it wasn’t determined whether the combined use with niacin can enhance the response of PDE5 inhibitors. Another limitation on the study results was the exclusion of the partner’s assessments. This would help to provide a more comprehensive assessment of the efficacy of niacin.
Minor side effects associated with erectile dysfunction medications include indigestion, runny nose and skin flushes. Sildenafil may cause temporary changes in your vision, and vardenafil may cause muscle aches and back pain. More serious side effects include hearing loss and erections that last longer than four hours. If you have cardiovascular problems, including a history of heart attacks or strokes, high or low blood pressure or vision problems such as retinitis pigmentosa, it may prove unsafe for you to take sildenafil, vardenafil or tadalafil. These medications may also interact poorly with some antibiotics, blood thinners and medications to prevent seizures and heart rhythm disorders.
According to the Centers for Disease Control and Prevention, ingesting levels of zinc in excess of the recommended dietary amount will result in diarrhea, vomiting, and stomach cramps. The maximum amount of daily zinc consumption recommended is 40 milligrams per day. Symptoms of too much zinc intake include nausea and headaches. If you have reason to suspect you have ingested too much zinc, contact a medical professional.
