When shopping for an effective testosterone boosting supplement you’ll quickly discover that most brands have gone all out on the marketing front.
There’ll be no shortage of bells, whistles and technical jargon designed to convince you this is the product for you. To best cut through all that razzle dazzle remember there are only really two things which dictate the quality of a booster:
Test Xtreme from Iron Labs might be cited as a good example of why you need both. Many components in Test Xtreme would seem to give it a great chance of delivering it’s goals of supporting testosterone production, aiding protein synthesis to enhance muscle growth and subsequent performance – yet reviews so far have been mixed.
Are the detractors right? And if so, what’s the problem?
We analyse go over the ingredients further down the page. First though … the scores
On the face of it, this should be a fantastic booster. There are several very strong testosterone stimulating ingredients in here such as DAA, zinc, vitamin D3, fenugreek, magnesium and the B vitamins (B5 excepted). Yet underwhelming results reported by a lot of users suggests a real problem. If the names check out then it must be the doses that are off, with weaker ingredients given more weight than they should have.
It’s all cloaked in a proprietary blend though, so we cannot say for sure. But there’s no smoke without fire, and this formula doesn’t seem to have set the supplements world alight.
Price (8/10) – Under £20 is Xtremely cheap for a test booster, especially ones with as many big name ingredients as this. However the reviews really are poor and we have no way of knowing the dosages of the ingredients. So despite it being cheap we have to clasify it as a waste of (not much) money.
Trustworthiness (7/10) – This supplement is made in the UK and therefore is subject to all the regulations which come with that. It has several well selected formula choices but because it chooses to conceal specific amounts within a proprietary blend (very probably at the expense of quality in this case) no full marks.
Testimonials (3/10) – Testimonials are unfortunately limited to reviews on retail sites and it has be said that a fair chunk of those on Amazon were unimpressed. Plenty of two star ratings complaining about a lack of results. Then again there were those who saw mild improvements, but generally opinion is so all over the place and lacking in detail it’s of little help to prospective buyers.
Company (8/10) – Iron Labs started as a company in 2009, but merged with Euro Nutrition in 2013, undergoing a significant revamp which saw them revaluate products on the basis of both up to date research and customer feedback. They are fairly unique as a company in that they focus entirely on testosterone supplements, fleshing out boosters such as Test Xtreme with post-cycle therapy and cycle support.
Users take 2 servings consisting of 2 capsules a day. 4 capsules is not too taxing but ideally we would’ve liked more sevings.Sucessful boosters go for 3-4 servings so those active ingredients don’t have a chance to drop off during your busy day.
No side effects have been reported to date.
Test Xtreme no longer appears to be available on Amazon.co.uk where we first saw it. Customers can still buy it at buysupps.co.uk for £18.99, which buys you a month supply.
One problem with this question is that all the active ingredients being closeted away inside a proprietary blend. Only the overall volume is available. Inevitably some are going to be stronger than others and without knowing the exact balance, you’re not getting the full picture. Oddly they have chosen to reveal how much of the first ingredient there is though.
– Not so strange after all. This amino acid is among the best natural T boosters available to us. It works on the brain to for the creation of luteinizing hormone, which helps dictates how much T we produce. D-AA also helps key players like growth hormone and follicle stimulating hormone. At 1640mg you’re hardly being short-changed, but if this choice can be disclosed, why not the others?
– Another strong selection. Up to 60% of the total T in our bodies can be rendered effectively useless by a protein known as Sex Hormone Binding Globulin. One of the best ways to convert it to free testosterone is magnesium. It has to be present in strong enough quantities however, which, unlike D-AA, we can’t say for sure.
– Maca is far from a useless choice, but its real strength according to clinical trials is boosting our libido. It does little to promote actual hormone production, but given what I’ve just said, I doubt many of us would say no to it anyway.
– A bit of a multi-purpose testosterone fuelling ingredient. Still widely used in certain types of cuisine, such as Indian, fenugreek is not only a potent libido enhancer but also has the ability to control blood sugars. This in turn helps regulate insulin levels, which if allowed to skew can have an extremely negative effect on health testosterone production.
A recent 12-week study of 50 male volunteers, aged 35-65, gave 500 mg/day of fenugreek extract to subjects and ultimately reported 90% of participants saw an increase in free testosterone. Unfortunately we don’t know if the amount here comes close to that.
A really important mineral for testosterone production as witnessed by zinc deficiency occurring in a high proportion of men with clinically low male hormone levels. Healthy amounts of zinc translate in to a strong output of luteinizing hormone, which as we’ve said is a vital precursor to testosterone. The lack of a specific dose is particularly a problem here though, as most people’s daily tolerance of zinc is 30mg. If Test Extreme surpasses this, side effects could definitely be on the cards.
– More commonly known as vitamin B5, this inclusion is the first one we would seriously question. Certainly some studies demonstrate it is able to raise testosterone, but usually only in large doses and so far only in rats. However much formula room is given to this, it could have been better used.
– AKA vitamin B6. B6 makes a great contribution to your hormonal balance by operating as an estrogen inhibitor. Not only does it work on the C2 pathway in the brain to reduce female hormone output, tipping things in favour of testosterone, it also dampens its impact once it’s bound to the receptor.
– Found in a wide selection of fruit and veg, many studies have shown it is not only able to actively help boost testosterone, but also limit estrogen, giving us our optimum man balance.
– Found in broccoli amongst other things, folic acid is essential for the creation of new cells in the human body. It also acts to repair muscle damage after training and promotes DNA and RNA synthesis. It encourages nitric oxide in the body, which a key physiological component in training that helps increase muscle mass.
– Several studies, including a 2012 report from Nnamdi Azikiwe University in Nigeria, have shown selenium can greatly improve levels of testosterone, and as an added bonus, its high L-Arginine content increases nitric oxide in the body, aiding energy and blood flow.
– Vitamin K2 as it’s also known. Often overlooked building block for T. K2 helps to maintain healthy levels of plasma in the testes, but it has also been seen to, when used in conjunction with vitamin D3, it can improve the effectiveness of the latter.
– Speak of the devil, D3. Called the sunshine vitamin because it is created when UV rays interact with our skin, levels of D3 go hand in hand with levels of testosterone, which is why our testosterone is uniformly lower in winter or sun starved areas. Unfortunately D3 only begins to stimulate testosterone at a high level, well above most RDAs. There’s no way of knowing if Test Xtreme gets close.
– Another B vitamin pseudonym, this time B12. B12 is great for aiding the effective transition of carbs into energy and encouraging strong blood flow. Again not a direct testosterone enhancer but a helpful support act.
Lots of the pieces are in place here for a great booster and only the mystery doses are at fault for the mixed reviews. That said they are not negative across the board and at a relatively cheap price, Test Xtreme may even be worth a try, but there are definitely much better bets out there to get your T flowing.
