- DIM is an effective aromatase inhibitor...sometimes
- DIM can backfire at high doses, INCREASING aromatase activity
- DHEA is a human steroid hormone
- Nolvadren XT is not a natural testosterone booster
- Pine Bark does not boost testosterone
We do not recommend this testosterone booster if you care at all about safety, side effects, or reliability. Nolvadren XT contains a synthetically-produced human sex hormone which not only poses serious health risk, but can also easily increase estrogen levels rather than testosterone levels. Similarly, the aromatase inhibitor used here can promote aromatase activity if you consume too much. The formula contains few proven testosterone boosters. All-in-all, Nolvadren XT is a lot of risk for very little potential reward.
Our Nolvadren XT Review
MAN Sports is a giant of the bodybuilding supplement industry. These guys produce some of the most widely-used and highly-rated sports supplements in the world. They typically focus on bodybuilding supplements – we have already reviewed MAN Sports Delta XT, which is another of their testosterone boosters. With one already on the market, why did they launch Nolvadren XT?
What does this testosterone booster do that is different to Delta XT?
How does Nolvadren XT claim to work?
According to the official MAN Sports website, Nolvadren XT delivers the following key benefits:
- Controls cortisol
- Blocks estrogen conversion
- Increases blood testosterone levels
That is a great, simple list of benefits for a testosterone booster to go for. Our favourite testosterone boosters typically work in this three-pronged fashion; reducing cortisol, reducing aromatase activity, and promoting testosterone synthesis.
If MAN Sports Nolvadren XT can actually do all of this, then it will rank alongside our top rated testosterone boosters.
So, does it?
Is Nolvadren XT a good testosterone booster?
Is it safe? What are the long-term health risks?
How does Nolvadren XT compare to the best testosterone supplements on the market today?

Nolvadren XT Ingredients
Have a look at the Nolvadren XT formula:
This is an extremely confusing formula. We say confusing because this does not look like a testosterone booster at all!
Nolvadren XT does not contain many proven natural testosterone boosters. The majority of the ingredients are completely ineffective for raising testosterone levels in humans.
We get a nice dose of Pine Bark Extract, which is both a powerful antioxidant and a blood flow enhancer.
We are given some Boerhaavia Diffusa Root, which is thought to reduce pain and inflammation.
Then there’s some 3Beta-Hydroxyandrost-5-En-17-One. This is just a formal name for DHEA. We really dislike it when manufacturers use the scientific names for well-known compounds to make them seem more exotic or interesting.
DHEA is an exogenous sex hormone. Nolvadren XT contains an androgenic sex hormone. It is not a natural testosterone booster. DHEA is not only a potentially dangerous hormone to consume orally, but it also seems to be extremely unreliable for raising total testosterone.
Finally, we come to a testosterone booster – DIM. Diindolylmethane is an estrogen inhibiting compound.
But that’s it!
There is just ONE testosterone booster in Nolvadren XT. The other ingredients might contribute to better health or performance, but they DO NOT actively promote higher testosterone levels in humans.
On top of that, DIM is a slightly less effective aromatase inhibitor than I3C in our opinion (although eh two compounds are related).
Let’s go through these three main flaws – lack of effective ingredients, use of exogenous sex hormones, and substandard ingredients – in more detail.
Main Weakness – Most Ingredients Do Nothing For Testosterone!
We were really expecting a lot more from Nolvadren XT. MAN Sports have a really good reputation, and they are clearly deeply involved in the bodybuilding industry. They know what we want from a testosterone booster, and they know what people like.
But MAN Sports Nolvadren XT doesn’t look like any other testosterone booster on the market right now – and not in a good way.
The majority of the ingredients don’t do anything for your hormone levels.
Take Pine Bark Extract, for example.
This is a wonderful source of antioxidants. While it is not widely used right now, more and more supplements are using Pine Bark Extract as a source of antioxidants instead of things like resveratrol or green tea extract.
Pine Bark Extract is particularly popular in nootropic supplements because the specific antioxidants and anti-inflammatory compounds it contains can easily cross the blood brain barrier. It also promotes healthy cerebral circulation by improving blood flow.
None of that has any effect on testosterone at all. These things might benefit your overall health and performance, but that isn’t what we want a testosterone booster for.
Major Weakness – Use Of DHEA
The most interesting ingredient is 3Beta-Hydroxyandrost-5-En-17-One.
Few of you will have any idea what this stuff is, but this is just because MAN Sports have used the most complicated name possible.
3Beta-Hydroxyandrost-5-En-17-One is just DHEA.
DHEA is a synthetically produced, exogenous human sex hormone.
As such, MAN Sports Nolvadren XT is not a natural testosterone booster. It provides a synthetically produced steroid hormone. THIS IS SOMETHING YOU NEED TO TAKE SERIOUSLY.
DHEA is produced by the adrenal gland. It can be converted into testosterone or into estrogen. Specifically, it can be converted into androstenedione, testosterone, and dihydrotestosterone, which can then be converted into estrogen via aromatase.
You might think that supplementing with DHEA would increase testosterone levels, but the studies on this have been far from conclusive.
One study found that DHEA supplementation increased serum DHEA levels and free testosterone levels but did not increase total testosterone levels in the blood.
Another study found that DHEA supplementation increased some male sex hormone levels in the blood, but not testosterone.
In our opinion, this makes DHEA extremely unreliable. It is clear that you cannot possibly tell whether the DHEA you consume will be converted into testosterone, androstenedione, estrogen, or any of the above.
This, coupled with the fact that that oral DHEA supplementation might be liver toxic or stressful to the kidneys, is why we would never recommend DHEA to anybody.
As such, we will not be recommending Nolvadren XT to anybody!
Minor Weakness – DIM Not The Best Aromatase Inhibitor
Every testosterone booster should contain some kind of anti-estrogen compound.
This can either be something to inhibit aromatase; the enzyme which converts testosterone to estrogen.
Or it can be something which turns more potent forms of estrogen into less potent forms.
DIM does both of these things. It actively inhibits aromatase, meaning that less of your testosterone gets converted to estrogen.
For a lot of guys, aromatase activity is the main cause of their low testosterone levels. Reducing estrogen conversion can have a massive impact on your physique, psychology, and overall performance.
DIM seems to significantly reduce estrogen conversion by inhibiting aromatase.
It also seems to convert estrogen metabolites into less potent, less estrogenic forms. For example, DIM has been found to convert 2-hydroxyestrone to 16α-hydroxyestrone, which has far weaker estrogenic effects.
So what’s the problem?
DIM sounds like an awesome testosterone booster!
The problem is that DIM can actually increase estrogen conversion and increase aromatase activity when consumed in large quantities.
DIM is found naturally in many plant foods, such as broccoli. If you’re eating a balanced, healthy diet, then you should already be consuming quite a bit of DIM. Supplementing with DIM could therefore easily put you ‘over the edge’ into dangerous territory.
If you want to naturally reduce estrogen conversion, we strongly recommend using I3C rather than DIM. It does not pose the same ‘backfire’ risk as DIM; large quantities are unlikely to promote estrogen conversion!
Nolvadren XT Side Effects – Is It Safe?
This is where we need to really take MAN Sports to task. They have included a synthetic steroid hormone in Nolvadren XT.
You read that right – MAN Sports Nolvadren XT contains a synthetic, exogenous human steroid hormone.
This hormone can convert into both testosterone, androstenedione, dihydrotestosterone, or estrogen (via aromatase). There is no way to know beforehand which hormone it will ultimately end up as, nor whether it will convert at all or remain as DHEA.
The dangers posed by this substance are therefore substantial and many.
For one thing, orally consuming steroid hormones is extremely taxing on the liver and the kidneys. These organs are not used to processing orally consumed, synthetic steroid hormones. So, they can become stressed, inflamed, and irreparably damaged.
Then there is the potential for excess estrogen conversion. Like other popular oral steroids (e.g Dianabol), DHEA can cause spikes in estrogen levels in men. This can produce side effects such as male breast tissue growth and erectile dysfunction.
Finally, there are the side effects of consuming DHEA when it does convert to testosterone. These will likely include:
- Hair loss
- High blood pressure
- High cholesterol
- Deepening of the voice
- Body fair growth
- Heart arrhythmia
- Mood swings
- Loss of sex drive
For a substance that might not convert into testosterone anyway, this doesn’t look worth it to us!
There are much safer ways to boost testosterone levels; you do not need to expose yourself to these significant risks.
We think it is incredibly irresponsible for MAN Sports Nolvadren XT to use a substance like DHEA without making it abundantly clear on the label!
Please remember the following facts while reading our supplement reviews:
- We are not doctors
- This is not medical advice
We don’t know you or your unique medical circumstances. All we are doing is highlighting the most obvious dangers based on our experience and research. You must do your own research carefully before using any testosterone boosters. If you have any concerns whatsoever, please talk to your GP.
If you believe that your testosterone levels are chronically low, your regular doctor might prescribe TRT. Always talk to a doctor; don’t self-diagnose!
MAN Sports Nolvadren XT Review Summary – Is It A Good Testosterone Booster?
We cannot possibly recommend Nolvadren XT to our readers.
There are several reason why we wouldn’t use this testosterone booster.
The formula contains ingredients that do not actively promote testosterone.
It uses a substandard and unreliable aromatase inhibitor – DIM can potentially backfire when consumed in considerable amounts, which is not good at all! We don’t want a testosterone booster that can potentially increase estrogen conversion!
Pine Bark Extract is an antioxidant and anti-inflammatory agent – it is not a testosterone booster in any way.
Boerhaavia Diffusa is a natural pain reliever and adaptogen – it does not influence your hormones.
But the main reason we could never recommend Nolvadren XT to anybody is the use of DHEA. This is a synthetic sex hormone which can convert into testosterone, dihydrotestosterone, androstenedione, or estrogen. It can cause serious, lasting, long-term side effects. It can increase the risk of heart attack and stroke.
DHEA is not a substance you can just play around with – it is a synthetic steroid that can have very serious consequences.
Not only is this a weak testosterone booster, but Nolvadren XT can easily backfire, increasing estrogen conversion and crashing testosterone levels even further.
MAN Sports Nolvadren XT is a potentially dangerous product that is all risk and very little potential reward.
If you want a supplement that will naturally support healthy testosterone levels in a safe, sustainable, healthy way, then take a look at some of our top rated test boosters right now. We would never recommend anything we thought to be dangerous.
