Our research has shown that this manufacturer has created a product born from science and clinical data. We found that this was the only product to contain 1500mg of Tribulus terrestris standardized to 95% Saponins sourced from the stem, leaf and fruit of the plant for a high level of Protodioscin which has been clinically proven to enhance athletic performance, bodybuilding, and help a wide range of health issues including heart and circulatory conditions, sexual issues, reducing blood sugar and cholesterol levels, skin conditions and kidney issues. Moreover, it includes BioPerine® for faster absorption and added benefits. Dosage is based on clinical studies which suggests that these guys are serious about what they do. We liked that it’s served in a vegan-friendly capsule as well as offers a 60-day money-back guarantee if you are not happy with the results. What have you got to lose? Nothing! 

Why do we recommend Approved Science Tribulus?

Main Benefits:

  • It contains 1500 mg of Tribulus terrestris for an unrivaled, powerful, highly concentrated dose.
  • It contains extract standardized to 95% Saponins, the active ingredient in Tribulus terrestris
  • It contains Tribulus terrestris extracted from the stem, leaf and fruit of the plant for higher levels of the chemical compound Protodioscin for added benefits.
  • It does not contain a proprietary blend to weaken the formula.
  • It contains BioPerine® which is a patented form of Piperine that has been proven to increase bioavailability, for a more effective product.
  • It does not contain any preservatives, artificial colorings, hormones, or unnecessary ingredients that may dilute the efficacy of the product.
  • We found so many supportive consumer reviews from users who had experienced excellent results, some within as little as a week.
  • Its daily suggested serving is the optimal potency as recommended by doctors for effectiveness and is supported by extensive clinical research trials and studies.
  • This manufacturer’s customer service is second to none, it provides excellent support and help. Furthermore, it offers an excellent money-back guarantee if customers are not happy with their results.

This unique formula was the only one that we could find that was backed by solid clinical data and included this specific blend of ingredients in their potent doses.   

Performance

As we age, there is a natural decrease in energy, libido and athletic performance. For men, this is a direct hit to the essence of who they are and can lead to a loss of vitality and even to depression. In order to lead long and productive lives, there are steps to take in both diet and lifestyle but those can only get you so far. Tribulus terrestris is the answer to these concerns. Used for centuries as a crucial part of Traditional Chinese Medicine and Ayurvedic Medicine, as well as being backed by scientific research, this exotic plant has shown it can boost drive, endurance and stamina. There are several key studies that help pinpoint the way when it comes to finding the most effective Tribulus supplement.

First and foremost, Tribulus supplements must contain a hefty and potent dose of Tribulus terrestris. A serving of at least 1500 mg is necessary.

Secondly, Tribulus terrestris must be standardized to 95% Furostanol Saponins. These are the active ingredients found in the plant that are responsible for all of their health benefits. Most supplements will contain half this amount for a much weaker potency.

Thirdly, Tribulus terrestris must be extracted from the stem, leaves and fruit of the plant. This ensures high levels of Protodioscin which leads to a surge of LH which naturally raises testosterone levels. Declining testosterone levels happen naturally as one ages. Unfortunately, this brings with it a loss of energy, decreasing libido and loss of stamina and endurance. 

Many companies who enjoy a positive reputation, take advantage of their good standing with the public in order to sell cheap health supplements. It’s so distressing how easy it is, which is why it is incumbent on every consumer to do their own fact-finding on any health product they purchase.

Approved Science Tribulus contains the purest and most effective form of Tribulus terrestris, in a large dose of 1500mg! This is double the dose that most companies use. What we really like is that it is made by a company that consistently uses clinical studies as a benchmark for the dosage of all their health supplements. There is also a money-back guarantee which can be claimed by speaking to their customer service agents who are real, not just bots!

Moreover, it is standardized to 95% Furostanol Saponins and extracted from the stem, leaves and fruit of the plant to increase vitality, energy, libido and many more health benefits in your body. On top of that, BioPerine® is added to the formula for faster and better absorption into the cells of the body.

Additionally, you will not find any ingredients in Approved Science Tribulus which shouldn’t be there. There are no added fillers, binders, additives or preservatives. There are so many products out there that do not fall within the realm of such high standards, offering artificial alternatives and all sorts of extras inside their formulas. It is a relief to be able to recommend a company that manufactures such a unique, well-researched product.

To summarize, Approved Science Tribulus uses top-quality natural ingredients, provides awesome results, has a caring customer support team and a great price. From what we saw, without a doubt, this is an extremely good product.

Quality Assurance

Over the last few years, we understand how consumers have grown skeptical of nutritional health supplements. This simply comes down to shady companies providing useless formulas that contain unrelated and non-useful ingredients or that add fillers or binders to their products. Often, these ingredients are not pure, or have been tested for quality and have no scientific validity as to why they have been included in the formulas. Not only is this irresponsible, but often quite dangerous. Truth being, there is absolutely no reason why anything artificial should be added. Natural and pure is the best.

On many nutritional supplements, the label states that the ingredients are either ‘active’ or inactive’. In simple terms, the active ingredients are the reason you decided to purchase the product and the ones that actually bring you the results you are hoping for. When you see a long list of inactive ingredients, beware, often companies will fill their products with unhelpful and potentially dangerous junk.

That is why, for us, Approved Science Tribulus is a product that does not fall within this category. Its formula contains only natural and pure ingredients backed by numerous clinical studies and research. It offers a simple philosophy that seems to work well – offer top-quality ingredients in the most effective potency, great price options with a terrific money-back guarantee and you won’t be disappointed.

Another aspect of taking supplements that contain a large amount of inactive or unnecessary ingredients is the lack of understanding of how these chemicals may affect existing medical conditions or medications. If the ingredients are bona fide and in their natural form, side effects or negative interactions are unlikely to be experienced.

We were very happy to discover that Approved Science Tribulus is manufactured in an FDA registered facility. What’s more, is that it is cGMP recognized and complies with the US Pharmacopeia’s standards for quality and purity. This suggests that this company takes what it does very seriously, and strives to keep its products safe, natural and effective – a mentality that we totally appreciate.

Value

Approved Science Tribulus comes at an affordable price with some excellent multiple purchase deals, allowing for huge cost savings for consumers. Also, this company is staunchly against any auto-ship programs, as they can be nearly impossible to cancel.

Nowadays, consumers need to be ‘smart shoppers’, carrying out as much research as they can about what they would like to purchase, in order to avoid wasting their money. There are many options out there that charge a lot of money for inferior products that simply will not deliver the results that they promise. This is disheartening and quite frankly, a bad and dishonest practice.

Orders are shipped within 24 hours, with the exclusion of any orders placed on weekends and holidays. They are wrapped and sent in discreet packaging, with no identifying marks on the outside, unlike other companies who often have embarrassing slogans or logos. Furthermore, this company provides a 60-day risk-free money-back guarantee. If you are not 100% happy with the results, you are able to return the product and receive a full refund. That shows strong confidence in its product and we totally support that kind of guarantee.

In Conclusion

When people are searching for a high-quality Tribulus product, they mistakenly either choose exorbitantly expensive products or cheaper ones that don’t contain a powerful dose of Tribulus terrestris. 

Approved Science Tribulus specifically contains the purest version of Tribulus terrestris with supporting ingredients to maximize its potency. They are:

  • 1500 mg of Tribulus terrestris for an unrivaled, powerful, highly concentrated dose.
  • Extract standardized to 95% Saponins, the active ingredient in Tribulus terrestris
  • Tribulus terrestris derived from the stem, leaf and fruit of the plant for higher levels of the chemical compound Protodioscin for added benefits.
  • BioPerine® which increases the absorption of the active ingredients for proven efficacy.

Additionally, there are other significant elements to bear in mind, such as third-party testing and comprehensive customer reviews that give us a great indication of how the product really works.

Of all the products that we reviewed, across all parameters, none compared to Approved Science Tribulus. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution for enhancing energy, boosting libido, restoring vitality and improving overall mood and well-being, you would be hard pushed to find anything better than Approved Science Tribulus.

“I’ve been taking the Approved Science Tribulus for about three weeks now and I can’t say enough amazing things about it. My energy levels have increased substantially and my mood overall has improved dramatically. I like that there’s no proprietary blend. The formula is solid with 1500mg Tribulus Terrestris and 5mg Black Pepper. This is another winner from Approved Science. I have always been pleased with the products they provide and have been switching over to them for the different supplements I take.”  – Gerry Greene

“My doctor was the one who told me about Tribulus and I’ve been taking it regularly over the last few years. Now and then I switch up brands just to see how they compare to each other. I tried Approved Science because of the high dose and normal pricing. A lot of times a high dose will come with exorbitant prices, but not so in this case. It has given me a real jump start. My testosterone and libido have increased because I am always in the mood. Much more than I ever was when I took different Tribulus products.  I am very much enjoying this high strength version. If you work out or want a libido boost, give this stuff a try. I hear it works for both men and women. I can vouch for the men, and I would love to see what it does for my woman as well!” – Scott Arnold

“This is a great supplement if you want to try Tribulus. I didn’t know so much about Tribulus, but I saw my brother-in-law getting real muscle definition for the first time in his life. I started reading about it and learned it’s all about the big increase in ‘drive’. That’s exactly what I saw when I took this product. I definitely experienced a real kick in my drive – both in the gym and at work. It’s a feeling of being motivated in whatever I do. I’m myself only bolder and better. I highly recommend giving it a try if that’s what you’re looking for.” – Jake Curtis

“I’m not the kind of person who normally writes reviews but given the amount of junk ‘herbal supplements’  out there, when I find one that EXCEEDS my expectations, it is worth writing about! I am 51 and I can see a tremendous overall increase in my stamina and energy levels. Even better, my lady friend is extremely pleased with the effects of this product. What really convinced me is when I didn’t order my next bottle in time and I could see a corresponding dip in my energy because of it. Not to worry, I have ordered enough for the next 3 months so that I won’t find myself in that place again!”  – Drake Fisher

“My husband started using this product and what a difference it has made to our lives! He is not someone who would ever put his name on a review but he was happy for me to write this because he has been so thrilled with the results. He had been noticing a drop in his energy and in his endurance levels. We both just assumed it was because he was getting older, but it was taking a toll on his confidence. We heard from friends that they had success with Tribulus so he gave it a whirl. Little did we know it would be so life-changing! He is up and at ’em whether it’s biking, swimming or between the sheets. That’s right, we still got it! Now it’s me who’s worried I won’t be able to keep up with him! This is one powerful pill.”  – Tamara Patton

“Since taking Approved Science Tribulus, I feel more grounded. My physician suggested I start taking Tribulus and said his patients found the most success by spreading the dosage out over the entire day. So I take one capsule in the morning and one in the evening. This works very well for me. I also find that when I eat food when I take it, it goes down easier and works better. I don’t feel as tired or as anxious as I had been feeling.  IF you need a real pick-me-up, this supplement is a winner.” – Brad Davis

“After years of taking caffeine pills for energy, I have discovered the benefits of taking Tribulus. I just assumed the lack of energy I felt was from getting older and needing more sleep. I didn’t connect it to my testosterone levels and I certainly never thought a natural product would work over something as powerful as caffeine. With Approved Science Tribulus I get the energy boost I need without any of the side effects. After using this product for only 14 days I find I have the energy and motivation to accomplish all my tasks throughout the day and I feel lighter and less stressed out. This supplement is definitely a keeper!” – Alex Dickenson

Do all Tribulus products work in a similar way?

The short answer is basically no, they do not. There are many companies that just ride the trends, producing inferior products with weak formulas in the wrong proportions. Many use incorrect ingredients, fillers, binders or even worse ingredients that can affect desired results, and even be dangerous.

What should I look for in an effective Tribulus formula?

  • It should contain 1500 mg of Tribulus terrestris for an unrivaled, powerful, highly concentrated dose.
  • It should contain Tribulus terrestris extract standardized to 95% Saponins, the active ingredient in Tribulus terrestris
  • It should contain Tribulus terrestris extracted from the stem, leaf and fruit of the plant for higher levels of the chemical compound Protodioscin for added benefits.
  • It should contain BioPerine® which is a patented form of Piperine that has been proven to increase bioavailability, for a more effective product.
  • It should not contain animal products to be suitable for vegetarians and vegans.
  • It should not contain any binders, fillers, additives, hormones, preservatives or artificial ingredients.
  • It must be 100% pure, natural and with no unnecessary ingredients that could reduce the effectiveness of the product.
  • It should be formulated using the same potency as found effective in clinical studies.

Are there any side effects noted when using this product?

Our research did not uncover any negative side effects when using this product. The ingredients that are contained within the formula of Approved Science Tribulus are all-natural and pure, what’s more, they are doctor-approved, so the lack of any negative effects is to be expected. That said, as with any supplement, we always recommend consulting with a doctor if you are pregnant, breastfeeding, have an existing medical condition or are taking any other medication.

What are the dosage instructions for Approved Science Tribulus?

The manufacturers of this product suggest taking 2 capsules per day, preferably once in the morning and once in the evening, before mealtime with a glass of water. 

As with any medication or supplement, always follow the recommended dosage instructions and do not exceed them as this poses health risks.

How long before I can see any results?

Results will vary for each person. For some, they will see changes almost immediately, for others it may take longer. It is different for each person. Other factors that affect results can include age, diet, and lifestyle so it is hard to say exactly. What you should look out for are those companies who offer a satisfaction guarantee. This suggests that they are confident that their products will deliver the desired results. And after all, if you don’t get the results you were hoping for you can always return the product. Approved Science Tribulus offers a great money-back guarantee and awesome feedback on how well this product works.

What price should I expect to pay?

The costs of products vary among manufacturers. Unfortunately, many are cheap, useless supplements that have been formulated without any science-based evidence to back them up. Some of these companies are selling their products for over $100 per bottle, which is very expensive. On average, the best supplements we found are selling between the $40-$50 price range. Often, when products appear cheaper, this is indicative of low quality or a low recommended daily serving, which will not bring the results you are looking for. Be aware. Read the labels.

Which Tribulus product should I buy?

As each person’s experience of a product is different, it is difficult to say specifically which one is the best. That said, based on several factors, we did like Approved Science Tribulus. We found, that from 50+ products that we looked at, Approved Science Tribulus had the best quality of ingredients, potency and strength, positive consumer feedback and the manufacturer’s customer service was excellent.

They also deliver very efficiently and quickly, using discreet packaging.
