We think having “xtreme” in the name of this testosterone booster is totally misleading; this is a weak supplement full of unproven ingredients. One of the primary ingredients in Test Xtreme is Maca Root, which has been repeatedly shown to be ineffective at raising testosterone levels. The main ingredient is seriously under-dosed. Fenugreek improves sex drive, not testosterone levels. We’re just left with some minerals and vitamins. All-in-all, Test Xtreme is a poor testosterone booster. You can get far better results using a more comprehensive fat burner.
Our Iron Labs Test Xtreme Review
Iron Labs Test Xtreme is currently one of the most talked-about testosterone boosters in the UK. It has a lot of reviews on Amazon, and there are quite a few threads about it in the main fitness and bodybuilding forums. So what is this product supposed to do? Why is it so popular right now?
The main merchant page for Iron Labs Test Xtreme makes a big deal about the zinc content, which they say “contributes to the maintenance of healthy testosterone levels”.
It also talked a lot about the effects of having higher testosterone levels, which include:
- Increased energy levels
- Reduced fatigue
- Maintenance of muscle mass and function
This is all standard stuff. We know that these supplements claim to produce these benefits because they will all naturally follow from having higher serum testosterone.
It is important that Iron Labs Test Xtreme claims to actually increase testosterone. Many supplement call themselves testosterone boosters, but they actually just treat some of the symptoms of low-T; they don’t actively treat the root cause of the problems.
So, does Iron Labs Test Xtreme really increase testosterone?
Is it safe? Will it cause side effects?
How does it compare to the best supplements on sale right now?

Test Xtreme Formula
Take a look at the Test Xtreme ingredients profile:
That is not the most powerful formula we’ve ever seen. Not by some margin.
At first glance, Test Xtreme looks like a weak testosterone booster.
Iron Labs could have chosen far better ingredients here.
For example, Maca Root is completely unproven; it seems to be effective as a libido-booster but not at increasing serum testosterone. Clinical studies have actually shown it to be ineffective for raising T-levels.
Fenugreek is similarly a sex drive enhancer, not a testosterone booster. The dose is low too, so you wont even experience the sharp rise in sexual desire associated with Fenugreek supplementation.
Iron Labs Test Xtreme uses a standard, basic form od D-Aspartic Acid, but it only provides 1700mg per serving. If you’re going to use less than 2000mg of D-AA, you really need to use a highly bio-available, more powerful analogue like D-AA Calcium Chelate.
All things considered, this one is a bit of let down. If you’re looking for a powerful testosterone booster, look elsewhere. Iron Labs Test Xtreme is not it!
Let’s go through these problems in more detail.
Problem #1 – Ineffective Ingredients
The main problem with Iron Labs Test Xtreme is the fact that it contains far too many useless ingredients.
A sizable chunk of the Test Xtreme formula is taken up by ingredients that have absolutely no effect on testosterone levels whatsoever.
For instance, the second largest ingredient is Maca Root.
This substance is a very common ingredient in testosterone boosters today. This is disappointing, because it doesn’t actually influence testosterone! Studies have found that Maca Root promotes sex drive and seminal quality in men; it does so effectively, reliably, and safely. But it does not do this via elevated testosterone levels.
Each daily serving of Iron Labs Test Xtreme contains 400mg of Maca Root. That’s 400mg of a substance which will not make a blind bit of difference to your testosterone levels.
Problem #2 – Low Dose Of D-AA
Another problem with the Iron Labs Test Xtreme formula is the D-Aspartic Acid dosage – it’s way too low!
Iron Labs Test Xtreme provides 1,640mg of D-Aspartic Acid. Just basic, run-of-the-mill, standard D-AA.
The scientific literature generally only deals with regular D-Aspartic Acid in doses above 3,000mg. There aren’t many studies out there which show a significant increase in serum testosterone using less than 3,000mg of standard D-AA. If you’re using regular D-Aspartic Acid, then you need to be using at least this much for optimal results.
If you’re using a more powerful, bio-available form of D-AA – like D-Aspartic Acid Calcium Chelate – then you can get away with using about 1,500mg. But not if you’re just using basic D-Aspartic Acid like we get in Iron Labs Test Xtreme!
This is really disappointing.
D-Aspartic Acid is an extremely reliable natural testosterone enhancer. It works well for most individuals. It has no known side effects. It is a staple in testosterone supplements for precisely these reasons.
Why low dose it?!
Problem #3 – Low Dose Of Vitamin D3
D-Aspartic Acid isn’t the only staple ingredient that Iron Labs Test Xtreme doses too low.
We also get given a paltry serving of Vitamin D3 – just 320IU, or 8mcg.
To put that into context, the best testosterone boosters on the market right now will generally provide more than 3000IU; 10 times more than we get from Iron Labs Test Xtreme! The very best products, such as Centrapeak, deliver a massive 4000IU of Vitamin D3 per daily serving.
Vitamin D3 acts almost like a prohormone in the body, such is the strength of its relationship with testosterone. Low Vitamin D is closely correlated with low testosterone; likewise, increasing Vitamin D levels proves to be a reliable way to increase testosterone levels. The relationship is dose-dependent – more Vitamin D means more testosterone.
Most guys are deficient in Vitamin D in the northern hemisphere. They work indoors, they exercise indoors, and they get virtually no sun in the winter months.
Supplementing with a large dose of Vitamin D can have a massive effect on your testosterone levels. You just need to be taking ENOUGH of the stuff! The 320IU you get from Iron Labs Test Xtreme is just not enough.
Iron Labs Test Xtreme Side Effects – Is It Safe?
We think Iron Labs Test Xtreme is a weak testosterone booster, all things considered. We don’t think it needs to have “xtreme” in its name – the only thing extreme about it is the lack of Vitamin D.
But a big benefit of a weak supplement is often a lack of side effects. That is exactly what’s happening here.
Iron Labs Test Xtreme looks like a safe testosterone booster for the vast majority of users.
We doubt many people are going to experience any side effects at all from Iron Labs Test Xtreme.
The ingredients are all widely used in sports supplements today. We understand how they work extremely well, and we know what they can and can’t do. We’ve read dozens of studies on each ingredient; none of them are thought to pose significant risks to health in either the short or long term.
The ingredients in Iron Labs Test Xtreme don’t even regularly cause mild side effects.
Of course, everybody is different.
We doubt 99% of people are going to experience any side effects while using Iron Labs Test Xtreme (or any positive effects), but there are always exceptions who prove the rule. You might have an unusual medical condition, allergy, or medication regimen which makes Iron Labs Test Xtreme unsuitable. This is why it is vital that you do thorough research before proceeding and seek medical advice if you have any concerns.
Please remember that we are not doctors and this is not medical advice. In order to stay safe, you need to do two things:
- Talk to a real medical doctor
- Do your own research thoroughly
If you experience any side effects whatsoever while using Iron Labs Test Xtreme, cease use, seek medical attention, and alert the manufacturer. We strongly advise you to get the opinion of your regular GP before you start using Iron Labs Test Xtreme.
Pricing – How Much Does Test Xtreme Cost?
At the time of writing, Iron Labs Test Xtreme is priced at around £17 per bottle.
Each bottle contains 120 capsules. A daily serving is 4 capsules, so a single bottle will last for 30 days (assuming you take it every day as you should).
That works out at a very cheap 56p per day.
But note that we say cheap, not good value.
In our opinion, even 56p per day is a lot to ask for this weak, low-grade testosterone booster.
If you’re serious about optimizing testosterone levels, then you’re probably going to have to take a multivitamin on top of Iron Labs Test Xtreme (because the doses of Zinc and Vitamin D are so low).
If you really want to get good value for your money, it’s often worth buying a slightly more expensive, but ultimately more effective, higher quality testosterone booster.
Iron Labs Test Xtreme Review Conclusion – Is This A Good Testosterone Booster?
If you’ve skipped our full Iron Labs Test Xtreme review and jumped straight to the conclusion, we’ll try to be concise.
We do not think that this is a good testosterone booster. Not by any stretch of the imagination.
Maca Root has been completely debunked – it enhances libido but does not alter testosterone levels in men, even at high doses.
Fenugreek improves libido too, but like Maca Root, it does not increase free serum testosterone levels. It improves your sexual appetite through other mechanisms.
D-Aspartic Acid is a good natural testosterone booster, but you really need to be taking more than 1,600mg of the stuff if you’re just using standard, basic D-Aspartic Acid. For generic D-AA, we recommend taking at least 3,000mg – the lowest amount used in the literature.
The Vitamin D has been dosed pathetically low too.
Honestly, we have no idea why they have called this an “extreme” testosterone booster.
There is absolutely nothing extreme about Iron Labs Test Xtreme. It is a weak, over-priced testosterone booster.
If you want to see real results, use a genuinely powerful supplement that has ingredients and doses backed by independent scientific data.
