Zyrexin
Zyrexin is a male-enhancement supplement designed to improve sexual health. It claims to work the first time a man takes it, with effects lasting up to 24 hours.
They have included Yohimbe in their formula, one of the world’s most popular herbal aphrodisiacs, as it has shown to increase sexual desire in both men and women. For men, it may also help to relax the smooth muscle of the penis. When men become aroused and the Yohimbe is working, this may allow more blood to flow into the caverns of the penis, naturally creating a stronger, tighter erection. This is turn can make sex a more pleasurable experience for both parties.
A commonly-used duo of Yohimbe and Horny Goat Weed is found in Zyrexin. Many state that these two herbs used together can produce drastic results in the area of sexual health. Horny Goat Weed is widely known to be an effective aphrodisiac. While Yohimbe can begin to work within half an hour, Horny Goat Weed can take a little longer to work, but still have good results. It not only can make a man’s libido regain itself, but it can improve the blood flow into the penis, helping the Yohimbe with this function.
Finally, Butea Superba can act as a PDE-5 inhibitor. This is the same science that many prescription medications for erectile dysfunction use. However, Butea Superba is not known for side effects like harmful medication.

This product was just like taking a vitamin. I did not feel any of the effects that I wanted. I had the whole night planned out perfectly. And then ended up with an unexpected ending to my night. I would have never guessed that I would purchase a product for this and it didn’t work! I will try another before I give up.

To me, Zyrexin is obviously just another natural pill with mediocre ingredients. This site is really helping me see the difference between a pill that will work and a pill that will not work.

if you are looking for a pill that gives immediate involuntary erections, or enlargement, don’t buy this product. If you have a serious E.D. issue see a doctor, no over the counter med will work for you.
if you are looking for a pill that assists you in getting and maintaining an erection this is a great product!
It does not work in the 45-1hr time frame, my results were about 2 hrs.
however after that it kept on working, I got a raging erection and had sex and then fell asleep with a stiffy, and then woke up with one and did it again…on one pill!
the side effects make you slightly nautious, with a little headache, and elevated heart rate, which can kill the mood quite quickly.
I have tried many products, but not all of them. out of the 10 or 12 products I’ve tried, this one works the best. and it should for $1.20 a pill.
walmart carries them for around $12 for 10 pills.
as far as raw boner power, this product does work as intended.

Typically I can get an erection but wanted to see how this might make things better. One pill had the opposite of the intended results. I could not get an erection even when I normally could. 2 pills produced the results that I thought it should. Im glad I just tried the one pill as an experiment and not when I needed it.

I found that if you take one of these pills with prescription ED medication such as Lavetra it greatly enhances the effects.

It might work for some, but man oh man–made me so nervous and jittery that it was just annoying : I just took
a trial pill to see what it would do, before trying it with the ladies.
Did have some effect on my erection, which was okay but the side effects were so obvious with severe shaking in my hands that it seemed like I just downed a six pack of Redbull. I really don’t want to even attempt it again with a woman–the results would probably really backfire.

My husband took 2 of these pills about 1 hour before sex. It did not help him at all. Then 4 hours later he got an erection when we were trying to go to sleep. He also got sick from taking it. He had muscle pain in his legs, nausea, restlessness, and slight headache. He basically just didn’t feel very good. I am a pharmacy student, and I researched the main ingredient (XANTHOPARMELIA) on a database I use called Natural Medicines. It said that this ingredient is unsafe and possibly toxic. I don’t think he will be taking this again, unless we are desperate. It scared me to death when he started having side effects 4 hours after he took it.

this stuff is crap. i call it legal speed! it ‘possibly’ helped a little, but not much. BUT..for the next 6 hrs my skin crawled and i felt like i wanted to just out of it–my date was less than pleased to say the least–buy at your own peril!

I must chime in on the effects of this product. I have actually tried it twice and I must say it does nothing at all. The first time I thought was a fluke, but the second time the same result. It definitely accelerated my heart rate to the point where is was very uncomfortable. Secondly, it gave me the jitters like taking caffeine. Lastly, I was unable to sleep for several hours afterwords which was not expected. Would I recommend this product to anyone? I certainly would not and wish there was a way to get a refund. SAVE YOUR MONEY!!!!

Gave me nausea and an upset stomach a few hours after I took it. Nothing else noted. So I paid $20 to feel sick. That’s great, isn’t it.

I can say it workes 1 pill a day not 2 people. taking to many of thease will give you side affects because your body isnt use to herbs like thease. take 1 a day if you Dont feel a Boner in about 6 hours after 2 days then stop taking this product.

No noticeable effect. I’ve tried it on five occassions (fair test?) and it did nothing for me. On the upside I didn’t have any of the side effects I have read about in previous postings. It’s back to Levitra for me. A lot more expensive, but it works.

I’m 52 and have been having problems getting it up for the last 2 months or so. Researched alot and decided I ‘d give this a try since I can get it at Rite Aid for $20. Took 1 pill instead of 2. After 3-4 hours and some partying I was ready to go. I lasted longer and pounded her hard the way she likes. The orgasm was awesome!. Woke up with a headache which could be the booze, I don’t know. I’ll try it again in a couple of days.

I took 2 pills as the bottle said. It took about 2 hrs for me to feel the effects, definitely a rock hard erection and an amazing orgasm. BUT…it made me extremely nauseous, gave me the shakes, made me sweat, and gave me a little headache. If your really need a boost to please someone extremely hot, go for it, but for me it wasn’t worth it, I felt like I was on drugs for 6 hrs it was ridiculous!

This product is the worst enhancer ive ever tried. Ive never had any problem lasting ling enough, but i wanted something to i could go for hours. I took 2 pills as the bottle said and i couldnt even be against my girl without feeling like i was going to ejaculated. Terrible product. Only someone unexperienced would think it works like it should!!

I had a week of no erections and got worried. Was going to see a doctor but thought I would try this as I feel great, don’t drink dont smoke am very healthy 44 year old. I took one at 6 pm and the second at 11 pm just to spread them out. By 2:30 I blew my girls mind with stamina and energy. I am simply sold, this product worked. No side effects at all. I also did some light excersise and drank a lot of water to promote blood flow.

I tried just one pill before dinner on an empty stomach. This happened: within 1 hour I had the chills, my blood pressure went up and so did my pulse rate. After another hour I started getting hot with uncontrolled sweating. Underwear was soaked, clammy cold hands and feet. My hands were shaking. Sex was the last thing that would come to my mind and an erection was out of the question under those conditions. The whole episode lasted about 7 hours. After that a shower and clean, dry clothes
Trying unsuccessfully to return the product.
