In the market of natural testosterone boosters, there’s a lot of confusion over which ingredients are right and which ingredients are wrong. Other factors come into play as well, such as the dosage and the company’s reputation.
Begging the question of all those factors we focus in on Test Xtreme, an “advanced testosterone support system” made up of natural ingredients and formulated by Iron Labs Nutrition.
Taking the direct approach to the features of this product, Iron Labs promotes Test Xtreme to have the apparent following benefits:
- Advanced sports supplement for use by males
- Helps to support testosterone levels
- Contributes to protein synthesis – the process by which muscle growth occurs
- Supports muscle performance
I’m not sure entirely if the first bullet point was necessary, but Iron Labs could be after those who are new to testosterone boosting altogether.
First, let’s learn about Iron Labs.
About the company
Iron Labs Nutrition is a UK based company formed in 2009. Later in 2013, the company formed with Euro Nutrition where the entire brand was revisited in terms of design and formulation.
The process for product production is apparently a “lengthy, research driven process at Iron Labs Nutrition – relying heavily upon study data and specialist recommendations, but also taking note of the latest trends and real-world user feedback” which is always good to hear.
Unlike most of the brands I review, Iron Nutrition is based entirely around Testosterone, supplying natural testosterone boosters, post-cycle therapy and cycle support. It’s rare for a product to be so open about making money off consumers who are using illegal anabolic steroids.
That said, they’re willing to put that kind of product out there, they must know their stuff.
The Ingredients and how they work
The serving requirements of Test Xtreme are 2 a day, with each serving consisting of 2 capsules. With a 120 in this product it should hold for around a month’s supply.
This is not the most ideal way to dose these kind of tablets, usually a servings that occur 3 – 4 times a day yield the most results in my opinion, however, Iron Labs seem to have tried to walk a fine line between convenience and effectiveness.
Now let’s look at the ingredients:
(Unfortunately, Test Xtreme’s Supplements Facts Table isn’t listed online.)
This product is a proprietary blend, but Test Xtreme have been kind enough to reveal the dosage of the D-Aspartic Acid.
D-Aspartic Acid 1640mg – Off to a great start, DAA is one of the key testosterone builders the body can have. Having been seen to raise the count of luteinzing hormones (which help release testosterone, follicle stimulating hormones and growth hormone), DAA also helps loosen the rate-limit of testosterone production.
Magnesium Aspartate – 60% of the testosterone in the male body is bound and unusable due to Sex Hormone Binding Globulin. It greatly diminishes the amount of free T, however Magnesium combats this by lowering the SHBG count and allowing more testosterone to be accessible to the body.
Maca Extract – Thought to be a good hormonal regulator, however Maca has been seen to only cause spikes in libido – it has no effect on testosterone levels.
Fenugreek – Rich in anti-oxidants, Fenugreek works by regulating blood sugar metabolism in the body which helps lower the risk, or occurring insulin resistance in the body which can cause diabetes and low testosterone.
Zinc Aspartate – This mineral has been seen to greatly aid testosterone levels by boosting them significantly when supplemented, it’s also been noticed for it’s aromatase inhibitor qualities. In trials, subjects with lower zinc levels were seen to produce more estrogen.
Pantothenic Acid – Also known as Vitamin B5. There is a very loose connection being made here. B5 has been shown to raise testosterone, but only in very large dosages when applied to rats. The same is not always true for humans, and if it is, there’s only so much space in 2 capsules.
Pyridoxine Hydrochloride – Also known as Vitamin B6. This is actually an effective aromatase inhibitor when given the right backing. By working with the C2 pathway in the body, B6 regulates the metabolism of estrogen after it binds to a receptor and suppresses the rate of its growth in the body.
Vitamin A – Found in a selection of fruits, vegetables and meats. It has been seen to increase testosterone, seminal volume and lower estrogen levels in men. It is a great benefit to the testosterone boosting process.
Folic Acid – Also known as vitamin B9. Which has showed promise at raising androgen receptor activity – essentially the good receptors that bind with testosterone and DHT.
Selenium – This is a nutrient commonly found in Brazil Nuts and has been linked to increasing testosterone in the human body. It is also high in L-Arginine which has been soon to improve nitric oxide levels in the body which helps greatly with a pump due to how it benefits the bloodflow.
Menaquinone – Or Vitamin K2, which is ideal for testosterone boosters, It takes more of a supporting role – K2 maintains a steady level of testosterone in the testes.
Cholecalciferol – Leaving one of the best til last, aka Vitamin D3, this is not so much a product as it is a hormone. D3 helps with the production of testosterone and has been seen to link significantly in various studies for it’s positive effects on testosterone levels – A must have in all T boosters.
Cyanocobalamin – More commonly known as Vitamin B12, this is used by the body to produce DNA, hormones and red blood cells. It also produces energy for the body by processing fats and carbohydrates.

So far there have been no reported side effects from this product. But being an almost entirely proprietary blend, the main concern with this product is for it being effective at all – Although the ingredients seem to be pretty impressive, the few that are not may be taking priority in this proprietary blend.
Pros and Cons
- Lots of good ingredients in this product
- D-Aspartic Acid, often overlooked
- Entirely a proprietary blend – no real evidence of how much is going where (Exc. DAA)
- Serving suggestions could be better – 3+ a day would be sufficient
- Some ingredients ineffective – in this proprietary blend could make all the difference
Test Xtreme Review Conclusion
Having looked at this product from various angles, I have not found it easy to make a suitable judgement.
The ingredients in this product are on the whole pretty good. The serving rate per day for Xtreme is not ideal but its not the worst I’ve seen either.
The problem that I have with this product is the choice it made to go with a proprietary blend.
In a way, this lack of transparency over how much of each ingredient is being used ruins the credibility of the product and makes it harder to trust the intentions of it, as we know there are some ingredients in there that do not fully work as testosterone boosters. What’s stopping them from being the main ingredient?
Until this proprietary blend is revised into something more transparent this product will only be awarded 3 stars.
