As men get older, they tend to experience a serious decrease in hormone production. One of the crucial hormones that our body fails to produce with time is testosterone, a hormone that is the base for various bodily functions and abilities.
Those who experience low testosterone levels will most likely find themselves struggling with muscular development and no matter how hard they work out, they simply don't see results. They may also fail to function properly in the bedroom, which is frustrating and embarrassing at the same time. While there are many different options available that can combat low testosterone levels, this review would like to focus on a more popular one called Cybergenics ISO-TEST.
Cybergenics ISO-TEST claims to be a powerful and high-quality supplement that can enhance one’s testosterone production easily. The product contains all-natural ingredients that stimulate the testosterone-producing gland, therefore boosting testosterone levels naturally. With increased testosterone levels, users are said to power through their workout routine and experience the full-body growth they are aiming for. The manufacturers state that this product can even better sexual performance, creating increased stamina and semen production.
All of this sounds great, but is everything true? We will take a closer look at this testosterone booster and summarize the results just for you. Keep reading!
How Does Cybergenics ISO-TEST Work?
Similar to other male enhancement formulas, Cybergenics ISO-TEST is absorbed into the bloodstream. There is no concrete information on how consumption should take place or if there are any unusual requirements. After ingestion, the natural ingredients present in the product will spread across the body through the blood to accomplish optimum distribution.
As a result, the testosterone will supply users with more energy, more muscular development, increased libido, sexual function, and decreased body fat.
Cybergenics ISO-TEST Ingredients
We are pleasantly surprised to see that the manufacturers of Cybergenics ISO-TEST actually included proper dosages for each of their ingredients. This significantly minimizes the chances of underdosing and side effects.
All ingredients are produced in FDA-inspected facilities and include:
Nettle Root Extract (30 mg) – A well-known herb that is indigenous to Africa and parts of Asia. Nettle Root leaves are believed to reduce allergy symptoms and aid in the reduction of inflammation in the body. Nettle root is also commonly used to reduce prostate size, prevent hair loss, and provide relief from urinary tract problems (1). This herb may also slow the growth of prostate cancer cells. However, as far as testosterone goes, Nettle Root seems to be ineffective. One study in particular found out that Nettle reduces the size of the prostate in certain patients, but did not affect testosterone production or levels (2) (3).
Eurycoma Longifolia (100 mg) – Also called Tongkat Ali and Long Jack, this is a Southeast Asian shrub often used in traditional medicine as a solution for low testosterone levels, erectile dysfunction, and infertility in males. Eurycoma Longifolia has been tested many times for its ability to treat erectile dysfunction (4). It also allegedly promotes weight loss, improves mental disorders, and may even lower blood pressure. Studies do suggest that Eurycoma Longifolia can elevate serum testosterone and even increase muscle strength and mass in men. However, more research is needed in order for us to have concrete proof of effectiveness and safety (5).
Dimethyl Chrysin (30 mg) – Better known as DIM, this is a chemical found inside our body as a result of consuming foods such as Brussels sprouts, cabbage, cauliflower, and broccoli. DIM is said to restore the balance of estrogen metabolites, and testosterone production. One enzyme in particular called aromatase, is responsible for converting testosterone in to estrogen (6). DIM also works by blocking estrogen but not the whole estrogen production process directly. DIM only blocks the aromatase enzyme and ultimately boosts the production of testosterone naturally. Experts also suggest that DIM plays an important role in protection against various forms of cancer, especially prostate related ones, due to its ability to inhibit the aromatase enzyme. Therefore, DIM can potentially prevent testosterone hormones from being converted into estrogen (7) (8).
Bioperine Black Pepper Extract (2 mg) – Or simply Piperine, this is an extract derived from black pepper. Bioperine is the main reason why peppers have their spicy taste. Supplement companies often add this ingredient since it can increase the absorption rate of other nutrients found in the formula (9). Bioperine also has other benefits. It helps in the prevention of many health conditions and is also said to be a great antidepressant. Bioperine can also strengthen the immune system, and increase the absorption of vitamins, selenium, beta-carotene, and coenzyme Q10 (10).
We definitely love the transparent ingredients label that the manufacturers of Cybergenics ISO-TEST decided to provide. However, while the formula is natural, some components like the Nettle Root Extract might be of great detriment to users who are sensitive, or who would want to supplement later in the course of the day. Unfortunately, what is included in this supplement is not the most well-round and necessary of ingredients.
For instance, Nettle Root Extract has not been shown to possess the ability to increase testosterone production and can lead to mild side effects in some users. Studies done on Eurycoma Longifolia are still inconclusive and need more concrete results. DIM and Bioperine are potentially solid ingredients that actually have adequate scientific proof of efficiency, without the addition of any side effects.
Cybergenics ISO-TEST Pricing
Unfortunately, it seems that Cybergenics do not have an official website anymore. However, customers can still purchase this testosterone boosting formula through reputable online retailers like Amazon and eBay. It is also impossible to purchase this supplement from brick or mortar stores. As far as pricing goes, Cybergenics ISO-TEST sells for $30 for a bottle of 30 capsules. This supplement does come with a money back guarantee, although some customers reported various problems when they tried to get their money back.
At the end of the day, we simply don’t see enough reason why we should recommend this supplement to anyone. Cybergenics ISO-TEST has a few potentially solid ingredients and a few positive customer reviews, however, it’s simply lacking some real scientific proof of effectiveness. For instance, the manufacturers fail to cite any real concrete results for Nettle Root and Eurycoma Longifolia, so it's unknown whether these ingredients will have any positive effect on testosterone and sexual function.
Bottom line, there are undeniably more reliable and trustworthy options available right now, capable of real results, so why waste your time with Cybergenics ISO-TEST.
