Vigorexin is purportedly produces stronger, bigger erections and enhances libido.
According to the company, “Vigorexin has proven itself that it is the ONLY male enhancement supplement that can get the job done!”
The official website claims Vigorexin has a 97.5% success rate, so I decided to look closer at the ingredients to determine whether this supplement lives up to manufacturer claims. My mind was blown when I discovered how effective this supplement is…
Are the Ingredients Powerful?
Vigorexin features several powerful ingredients that are listed on the official website. Ingredient amounts are not listed, but appear to be listed on the bottle. We don’t have a bottle so it is hard for us to really assess the ingredients, but will provide you with some general information.
This ingredient’s ability to enhance libido are promising.
During a 20-day study, athletes supplemented with tribulus terrestris. Results show blood testosterone concentration increased during the first 10 days of the experiment. 
Tribulus terrestris was also analyzed in an organ bath study for its ability to influence erection quality. The supplementation resulted in relaxation of the corpus cavernosum (sponge-like area of erectile tissue that contains blood during erection). 
I was unable to find clinically effective doses, unfortunately.
Horny Goat Weed
Horny goat weed is studied for its ability to combat erectile dysfunction and ejaculatory problems. However, one medical authority indicates there isn’t enough reputable, strong evidence to support its use. Also, side effects of long-term use include dizziness, nosebleed, and dry mouth. 
One unpublished study by Steven Lamm, M.D., reveals a horny goat weed formula influenced sexual satisfaction felt in 60% of healthy males and 45% of men who were also taking Viagra. 
Catuaba is used to enhance sexual arousal and ameliorate sexual performance, but online medical authorities indicate there is no real conclusive evidence to support its purported benefits. 
When administered in 200 mg doses per day, eurycoma longifolia was shown to improve semen quality parameters like volume, motility, and concentration. 
Testofen is patented fenugreek. A clinical study shows 600 mg Testofen increased free testosterone levels and positively influenced body fat reduction. 
How Should It be Used
Vigorexin is a male enhancement supplement taken 20-30 before sexual activity or can be taken on a daily basis.
Vigorexin may take effect quicker in some individuals, so ingestion time may be modified to produce optimal results.
Also, users may assess tolerance by taking only 1 capsule in the beginning. If Vigorexin is received favorably and no adverse effects are seen, increase the dose to the recommended amount.
Is Vigorexin Expensive?
Each Vigorexin bottle provides a 30-day supply and retails for $39.99. The official website, Vigorexin.com, also offers deals on multiple bottles. Here is a look at the pricing options available:
• 1 bottle: $39.99
• 2 bottles + free shipping: $79.99
• 3 bottles + 1 free bottle + free shipping: $119.99
• 4 bottles + 2 free bottles + free shipping: $159.99
What Are Users Saying?
There are some testimonials on Vigorexin.com. Here is a look at some of them:
“I tried a lot of other products but this stuff works, and most of all, it stays in your system for 24 hours, it’s great. It works when I need it to, and if I don’t need it I still take it because it makes my libido go crazy for sex! For any man out there, if you are looking for something that’s healthy, no side effects, no headaches, no nausea, this stuff is great.” –Tyson
“My girlfriend has never been happier. I am able to last long enough to get her to climax. I’m just so happy that I found out about it.” –Trevor
“For the first time since my honeymoon we are having sex multiple times per day and there is no way I could do it without Vigorexin. I think everyone should give it a try.” –Chase
I look forward to reading user reviews as they become available.
Is Vigorexin Worth It?
Vigorexin’s ingredient profile is promising with extracts shown to ameliorate sperm quality, enhance testosterone levels, and induce relaxation for optimized blood flow.
The pricing options on the official website are affordable and appear to be a terrific deal.
