Potentially Dangerous Ingredients

LAST UPDATED: October 2018.

Author: Ben has spent the last three years collating information and findings from analysing research papers and his own personal experiences while documenting them on this site.

Prior to this he graduated from university in 2005 and followed the predictable corporate trajectory working for a number of multinational companies which he found rather unfulfilling.

Always read the Label

As supplements gain increasing popularity to increase strength, size, cut fat, improve immunity or even recharge your brain, it is important to ensure you know what you are consuming.

Supplements are not regulated like food and drugs; therefore, it can open the floodgates to unscrupulous manufacturers who will load products with ingredients without much thought to the potential outcome.

‘The U.S. Food and Drug Administration (FDA) does not have the authority to review dietary supplement products for safety and effectiveness before they are marketed.’ [1]

Many people purely buy supplements based on the ‘look’ of the product.

They buy based on brand name and the claims, many of which are untested, proven or have any scientific evidence to suggest these claims can be fulfilled.

In fact, many products even hide the exact quantities of the listed ingredients behind what is known as a proprietary blend, a proprietary blend effectively allows a manufacturer to mask how much of each ingredient is present.

This means the big hitting and popular ingredients can be included with trace amounts pulling in sales all the while the whole product can mainly consist of a filler or bulking agent.

Not only will it not work, it is a huge waste of money.

However, in some cases a proprietary blend maybe a blessing.

Sure, you’ll be out of pocket and disappointed but if the product is mostly rice powder it is at least harmless.

We at Testosterone Junkie read through each and every ingredient of the products we test and review.

We wade through scientific studies and journals from reliable and scholarly studies – unlike the 2nd Gulf War we base our conclusions on real evidence and not Wikipedia or someone’s invalidated opinion based on nothing more than a hunch.

However, we have not reviewed every supplement on the market, yet.

So, for you, it is a good idea to have a basic understanding of the potentially dangerous ingredients that are awash in many supplement products out there.

Now, pretty much anything can be potentially dangerous in the wrong hands, you can drown yourself by drinking too much water [2] for example and if you eat approximately 25lbs of chocolate it can be very toxic.

However, any decent and well researched product will not include anything that has the potential to be harmful.

It is these kind of brands or manufacturers who are in it for the long haul by offering a quality product and not just to make a quick buck on Amazon or eBay.

Many of these ingredients have differing names too.

So it can be hard to always keep a track of them, as a result we have included the more obscure names as well to try and cover all bases.

If you are ever in doubt just run a quick internet search.

A quick tip.

If you run an ingredient through a search engine and the first page of results are merely websites exclaiming the virtues of the ingredient, it is highly likely that it will not be an effective.

Most natural ingredients will have studies available either by universities, state run scientific resources or online libraries.

So let’s take a look at some of the ingredients that you should avoid:
