Approved Science Testosterone Booster

If you’ve lost your youthful vim and vigor, you would be wise to try Approved Science Testosterone Booster. Of all the Testosterone boosting supplements currently available on the market, this is the one which deserves your undivided attention and very likely, the one that will change your life!

This product contains the highest potency of clinically-proven ingredients for addressing both the physical and psychological challenges resulting from declining Testosterone levels. It’s clear that each ingredient is carefully handpicked and selected. This is the only product we found that contains a significant dose of Tribulus terrestris as well as Tongkat Ali in order to drive up levels of free Testosterone.  Additionally, it also contains ZMA which is a blend of Zinc, Magnesium and Vitamin B6, researched and shown to boost Testosterone production. Further ingredients such as Vitamin D are included to activate existing Testosterone in the body by releasing Testosterone that is bound to Sex Hormone Binding Globulin (SHBG). Additionally, Fenugreek and Red Clover work to block the conversion of Testosterone into an altered and inactive form of Testosterone.   

Additionally, this product does not contain any additives or preservatives and is totally 100% safe to use with no long-term side effects.

Iron Brothers Testosterone Booster

With a promise to increase strength and libido naturally, we were extremely keen to analyze the ingredients found in this Testosterone Booster from Iron Brothers. At first glance, we were pleased to note the extensive ingredient list. It seemed as though Iron Brothers covered all their bases. However, upon closer inspection, we noted that there is a significantly smaller dose found in this supplement than what is included in the Approved Science Testosterone Booster. Lining up the numbers side by side is proof enough that you get what you pay for. 

Here are some examples: Tribulus terrestris 500mg (compared to Approved Science with 600mg), Tongkat Ali 50mg (compared to 150mg), Fenugreek 300mg (compared to 500mg) and Vitamin D 25 mcg (compared to 50mcg). These examples illustrate the difference between ingredient levels in the two Testosterone supplements. The ingredients are there but their dosage is slashed. Therefore it may not provide the optimal boost of Testosterone needed to see a difference in your lifestyle. Overall, this amounts to the Iron Brothers Testosterone Booster product being placed as our second choice. 

Furthermore, we find that the price reflects the ingredients inside. Since there is a lower dose of ingredients as well as missing ingredients, you can expect to pay a more modest fee. On the one hand, it makes the product affordable, but on the other, it is unclear how powerful this product really is. We were looking for a breakdown of ingredients and their proven benefits but, we were disappointed.

The final piece we look for is a money-back guarantee. Depending on how strict or lenient returns are handled is an excellent indicator of how likely a product is to actually work. In this case, Iron Brothers offers 30 days to return a product that is in its original packaging. There is no mention of returning a used product. We like to warn consumers before they try a product they will not be able to return. There are many products on the market that will allow you to try before you return. We advise consumers to seek out those products so as not to waste their hard-earned cash.

Cybex Biotech SizeVitrexx

SizeVitrexx by Cybex Biotech wants you to believe that it’s formulated with proven ingredients and backed by MIT professors. Indeed the product website is full of impressive graphics and patents. However, amidst all the flash, there are some rather large holes in their narrative. One of its main selling points is a patented ingredient called Butea Superba. However, there may only be a very small amount included in this product. The consumer can’t know for sure because there is no amount listed on the ingredient label. Another oddity are the MIT researchers. There are names and photos of these supposed researchers, however, there is something that doesn’t look quite right. For one thing, the images are not professional university photos but rather blurry, amateur pictures. For another thing, although the last names of the researchers are different, a Google search reveals that the researchers are married to each other. Further research throws serious doubt over their actual connection to the esteemed MIT university.

Delving further into the product ingredients, we found that the formula is devoid of any of the ingredients we usually look for in a Testosterone boosting supplement. Additionally, the ingredients which are included are in proprietary blends. Manufacturers will include proprietary blends in order to avoid having to list the exact quantities of their ingredients. This makes it difficult for consumers to truly understand what they are buying. 

Our main concern is centered on the manufacturer itself. The website seems to be trying too hard to convince the consumer. There are bold scientific charts and graphs and quotes from clinical studies. However, if you read closely, these studies aren’t proving this product’s efficacy! Is this manufacturer hoping to confuse people with scientific mumbo-jumbo? If this was truly a high-quality product, we think they would not have had to try this hard.
