Overall we like this product. The formula is good (although it could be better), the price is good, the company behind it is good (although again, it could be better).

Challenging for the Europa Cup positions.

TNT Test Your Limits Review

TNT Test Your Limits by UK based TNT Supplements is a great example of why there is no point in buying a ZMA product. It contains the same amount of B6, Zinc and Magnesium that you’d find in a ZMA product, but also a whole lot more.

But … is it good enough to fulfil the manufacturer’s bold claim;

“TNT Test Your Limits Test Booster is THE strongest legal testosterone support supplement available today!”

They are certainly not shy or lacking confidence.

TNT Test Your Limits

Does TNT have the explosive power to blow away the competition? Let’s find out…..

How Does It Work?

First of all – they have fully disclosed the formula. Hardhats off to them. What are the highlights?

At a Glance

  • Magnesium & zinc included to help free T and overall T
  • Includes great testosterone stimulators like D-Aspartic Acid (in a reasonable dose) & vitamin D3 (in an ideal dose)
  • Estrogen controlled with vitamin B6
  • Fenugreek assists with insulin levels and blood sugar

We’ll check out all this in more detail after the scores

Ingredients
8/10

The ‘Testosterone Enhancement Amplifier’ part of the formula is well thought out. Zinc and magnesium are strong testosterone boosters and dosed effectively, but the D-Aspartic Acid is slightly underdosed to make way for a high serving of Fenugreek (itself an excellent test booster). The inclusion of Beta Ecdysterone could be beneficial. B6 is a great inclusion but it is really part of the ‘Anti Cortisol and Estrogen Regulator’ component.

We are not quite as impressed by the ‘Anti Cortisol and Estrogen Regulator’ part. It would be making waves ten years ago but the inclusion of debunked 5-methyl-7-methoxy-isoflavone has us questioning the formula. 5000iu of Vitamin D3 is spot on, though that really should be categorised under ‘Testosterone Enhancement Amplifier’ (just to be pedantic).

They also include cognitive enahancers, which may have been better left to the Nootropic market.

Overall a very decent formula although there could have been more included.

Price
9/10

It’s a good formula, and at £27.99 (about $35), it’s at a reasonable mid-range price too. Widely available in the UK but may harder to source further afield.

Trustworthiness
6/10

We generally don’t like exaggerated copy claiming miracle results. There’s not much to complain about in relation to the product, but we are marking down trust based on the testimonials section below.

Testimonials
2/10

The product scores poorly in this department I’m afraid, mainly due to the obviously fake Amazon reviews (possibly orchestrated by Flash Geezer? See below). Often a fake Amazon reviews compaign is done pretty lazily, Indonesian micro workers with bland generalizations like ‘Great product’ or ‘Highly Recommended’. These ones are a lot more cunning, they have been well written.

If you look at the Amazon listing for this product you’ll see eight (at time of writing) 5* reviews. All 5* reviews, nobody scored it lower. But you’ll see that over half of the reviewers are called ‘Amazon Customer’. If you click on their name you’ll see all their other reviews.

And reveal the deception!

Every one has reviewed all the other TNT products on Amazon. And no other products at all.

These reviews are fake as far as I am concerned, I don’t trust a word of them.

Company
6/10

It’s as if the TNT website is the lovechild of two polar opposites. On one hand there’s the sensible and level headed person who puts in the warning about keeping it out of the reach of children. And advises professional athletes to consult their own federation in relation to their own sports rules on supplements.

Then on the other hand there’s Flash Geezer, the market trader who has big scratchcard style adverts for ‘Instant Cash’ and ’10K Cash Giveaway, Instant Win’ in the masthead of the website. As pointed out above, the Amazon reviews have Flash Geezer’s hallmarks on them.

I think Mr Sensible concocted the formula, which is good. He needs to reign in the copywriting of Flash Geezer though, anybody who has followed the TestoFen class action will know that it’s incredibly risky to emblazon the words ‘CLINICALLY PROVEN’ in relation to these kind of ingredients.

The question is: are Mr Sensible and Flash Geezer two different people? … or are we witnessing some kind of hideous supplement Jekyll and Hyde?? If you have seen them in the same room at the same time then please let us know via the comments at the bottom.

How Do I Take It?

4 pills a day, first thing in the morning and last thing at night. The manufacturer recommends it is taken in cycles of 8 weeks on and 4 weeks off.

Any TNT Test Your Limits Side Effects?

We wouldn’t anticipate there being any side effects based on the formula and dosages.

Where Can I Get It?

Available on Amazon for around £28/$35 and other supplement retailers sites for similar amounts.

Ingredients – In Detail

TNT Test Your Limits
vitamin-d3-thumb

Vitamin D3

Right on the money with the dosage, 5000iu is the amount recommended by the Vitamin D Council. A number of well conducted studies have demontrated that vitamin D is crucial to healthy test levels, for us it’s a must have ingredient for a top natural test booster.

http://www.ncbi.nlm.nih.gov/pubmed/21154195
http://www.ncbi.nlm.nih.gov/pubmed/20050857


vitamin-b6-thumb

Vitamin B6 (as Pyridoxine HCl)

It helps stimulate androgens, which are crucial for kick starting T, sending a message to the testicles asking them to increase levels of the hormone.

It also reduces estrogen by affecting the C2 pathway in the brain to slow it’s production. It reduces gene activity to minimise the female hormone’s influence once it is bound to a receptor. 10.5mg per serving is a lot, more than enough to have an effect.

http://www.ncbi.nlm.nih.gov/pubmed/6727359
http://press.endocrine.org/doi/abs/10.1210/endo-32-1-97


fenugreek-thumb

Fenugreek

Fenugreek is a potent libido enhancer – never a bad thing – but it also serves to regulate blood sugars in the body, reducing insulin resistance which can inhibit testosterone. It has been shown to deplete production of the sex binding hormone globulin and with these levels lowered; more testosterone is left flowing freely and is able to be used by the body.


Beta Ecdysterone

Part of a class of compounds similar in structure to androgens. Have been called by some researchers as;

“behaving similar to anabolic steroids putatively without the androgenic effect”

Their safety profiles are greater than anabolic androgenic steroids. Positive benefits of ingestion could include lower cholesterol and blood glucose, it is seen as healthy for the liver and intestines by increasing protein synthesis rates.

Unlike the previous ingredient this shows a lot more promise. However, it is promise and a lot more research is needed in human studies before this can be declared an out and out test boosting star ingredient. A lack of human trials (other than a successful in-vitro study of human foeteses) prevents us from giving this a ringing endorsement.


zinc-thumbnail

Zinc

Zinc is important to release of hormones for Testosterone, such as Luteinizing Hormone. Studies have also demonstrated that zinc also promotes levels of serum testosterone in men.


magnesium-thumb

Magnesium

Magnesium is vital for releasing free T. Up to 60% of the testosterone in our bodies can be tied to a protein called sex hormone binding globulin (SHBG). That’s bad news as in this state supplies are unusable.

Magnesium assists in lowering SHGB levels, freeing up more of that T and letting our systems make use of it.

Sarcosine

Also known as N-methylglycine, Sarcosine is a cognitive enhancer which would normally be found in a Nootropic rather than a test boosting supplement. It is also used in daily dosages of around 2000mg (it is dependant on body weight) to treat schizophrenia. To be fair the dosage in TNT Test Your Limits is only 1/7th of this at 304mg, but still … personally I wouldn’t be happy taking anti-schizophrenia medication in a supplement. Especially when it has nothing to do with the purpose of the supplement (ie, it doesn’t boost test).

There is no evidence it could be dangerous, although there is some evidence it is a biomarker for prostate cancer. Meaning that whilst it doesn’t cause cancer, levels of it can indicate the presence of cancer cells.


Phosphatidylserine

Another ingredient that you might associate with Nootropic supplements, Phosphatidylserine is an amino acid found in fish which effects cognitive function. However in this case it also lowers cortisol, which is more relevant to testosterone boosting.

The standard dose is 100mg daily for older people aiming to stem cognitive decline, it can be up to 200mg in young people suffering attention deficit disorder (where is has been used in studies) . TNT Test Your Limits has a 224mg daily dosage.


5-methyl-7-methoxy-isoflavone

This particular flavone was originally synthesised by a Hungarian company called Chinoin. The patent expired in 1997 which was when the supplement industry started to market it as a musclebuilder / fat burner that gave all the benefits of anabolic steroids without any of the side effects.

It is marketed on its ability to decrease cortisol levels, increase protein synthesis, and improve overall recovery from exercise. However studies conducted on resistance trained human participants have not been nearly as impressive as the studies on animals.

A study conducted in 2006 (when this compound was being heavily marketed as a ‘wonder supplement’) included anabolic/catabolic analysis of bloods and showed no statistical differences in;

  • Active testosterone (AT)
  • Free testosterone (FT)
  • Cortisol
  • The AT to cortisol ratio
  • Urea nitrogen
  • Creatinine
  • The blood urea nitrogen to creatinine ratio

Verdict: The headline act 10 years ago, since debunked as ineffective in humans.

d-aspartic-acid-thumb

D-Aspartic Acid

D-AA is an amino acid which works within the brain to release beneficial building blocks for T. Luteinizing hormone (LH) – which is crucial to the regulation of the testes – growth hormone and follicle-stimulating hormone have all been shown to be stimulated by D-AA.

Overall

Overall this is a reasonable product. The formula is decent, but not perfect. The price is good. I think this company will do well over time, they are new and they’ve made a few mistakes so far.

If they clean up their act in relation to planting reviews and stop promoting themselves like some market trader on a stall then they could do well.
