Delta XT is a herbal testosterone booster from supplement company MAN. Great to see that their goals are as straightforward as their name – raise T, limit estrogen, support muscle growth, cut workout recovery times.
We’re happy to report that Delta XT keeps it simple with ingredients too. All components are clearly named and dosed. No proprietary blend in sight. At a glance there’s a lot to like here but let’s take a closer look and see if the initial promise holds up.
How Does Delta XT Work?
- Diindolylmethane for estrogen suppression
- Fenugreek regulates blood sugars and control insulin levels
- Minerals magnesium & zinc included to help free testosterone and overall testosterone
- Libido boosting with Maca
- B6 stimulates testosterone production in the testes
We fully analyse the ingredients and the dosages chosen later in the article. First though … the scores
Delta XT actually has some really strong ingredients, even if we do think they’re a little over enthusiastic with a few dosages. B6, magnesium, zinc, and fenugreek form a solid foundation of T boosting and estrogen suppression. Even if DIM and epicatechin still have something to prove. Delta XT loses ground on what’s not included. Maybe if they hadn’t gone too big elsewhere a few more important adds could have been made.
Around the $30 mark is mid-range and for what you’re getting it’s probably about right. We can’t give it full marks for the problems above, plus the method of serving will lower effect. Most of the active ingredients in Delta XT are quality so if you’re looking for a budget option, this is worth considering.
There are no actual testimonials on the Man website, it’s mainly just explaining about the company’s ethos and directing you to retailers of the supplements. This means you’re left to judge from reviews on those outlet web pages. Such reviews are variable in quality and detail, so we can’t give full marks, but generally speaking, feedback is positive.
We couldn’t find any major complaints about this product and of course they don’t use proprietary blends so all the ingredients are named and dosed individually. More than that though, the company use a system called Micro Batch, which is similar to the concept of a Micro-Brewery, except with supplements. Basically the products are produced on site and not sent off to be mass produced. This isn’t essential as long as the factory applies with government guidelines, but it’s still a nice touch.
Man produce a wide range of products besides this testosterone booster, including a sleep aid and fat burner amongst others. They’ve fostered a real community spirit among users and appear to be growing in popularity. It’d be nice if they had a bit more of a global reach but besides that it’s difficult to fault them.
How Do I Take It?
This brand recommends that you take 3 capsules per one serving 30 minutes before bed every night continuously for 8 weeks, then give your body a rest for 4 weeks. This seems very odd to us.
Typically your testosterone will peak in the morning after a nights sleep and slowly ebb away throughout the day. Dosing a booster to be taken in the evening doesn’t help to flatten the curve, it accentuates it even more. Most boosters help to promote testosterone production through the day when it would normally start flagging.
Any Delta XT Side Effects?
We wouldn’t expect to see any side effects based on these ingredients.
Where Can I Get It?
Customers can get Delta XT from a range of online retailers giving you the option to shop around a bit, but typically we found it priced around the $30 region, for 84 capsules making up 28 servings.
MAN Delta XT – In Detail
Vitamin B6 (as Pyridoxine HCl)
In a testosterone boosting context, B6 really is the standout B vitamin. It works on the C2 pathway in the brain to slow the production of estrogen as well as reducing gene activity to minimise the female hormone’s influence once it is bound to a receptor. With estrogen suppressed, there’s nothing standing in your testosterone’s way. 10.5mg per serving is a lot, more than enough to have an effect.
Magnesium (as Aspartate)
Magnesium is great for helping our free testosterone, which is distinct from our overall testosterone because it is not bound by the protein Sex Hormone Binding Globulin and inhibited from direct use. Up to 60% of the male hormone in our system can be tied up like this so plenty of magnesium to free it is welcome. 450mg though is getting up towards the safe daily limit of this mineral at 500mg and to be frank about a quarter of this could do the job, so we hope other ingredients haven’t lost out elsewhere.
Zinc is another strong choice because it is one of the best stimulators of luteinizing hormone, which is important for dictating how much testosterone we are able to produce. Men with inadequate zinc levels routinely present with lower testosterone so safe supplementation can be a great idea and 30mg is right on the money.
Fenugreek Seed Extract
Fenugreek is widely used in Indian cuisine and has a great reputation as a libido booster. Other benefits include an ability to control blood sugar. This helps balance insulin which, if allowed to get out of balance, is bad news for T. Studies also suggest it can limit SHGB activity, upping our amount of free testosterone. 500mg is a pretty huge volume though and it does beg the question whether a smaller but still effective amount would have left room to strengthen the supplement in other areas.
Arguably the first ingredient listed to take its eye off the T producing ball (which is accidentally a much more literal turn of phrase than I meant it to be.) While maca root is considered an aphrodisiac in many cultures and has shown some ability in that area, unlike fenugreek, it’s not dual purpose and will do little or nothing to stimulate hormone levels. That’s why we’re sure this time a whopping 500mg is a waste.
Here we have a nutrient found in broccoli and other leafy green veg. DIM was shown to have anti-estrogen effects in a 2011 pilot study when dosed at 250mg as it is here. However other trials have shown it can also increase estrogen, so it’s a gamble.
This isomer found in tea is sometimes called catechin. A study from Taiwan in 2010 found that this component was able to cause a T increase in rats, though again there’s not much in the way of human studies. Even though there’s only 100mg, we still feel that constitutes Delta XT taking a bit of a punt.
Delta TX is not without its issues; it’s missing a couple of basics we like to see in our booster and the doses are a little over the top, but not dangerously so. That said, it does include (for the most part) a strong line up of effective ingredients. It’s not the best booster out there but for roughly $30, it’s a good option.
