Are Testosterone Boosters Effective? Can Testosterone Supplements Increase Muscle Mass and Libido?

Don’t take our word for it. Do your research. Compare the labels. If you’ve been following our posts, you’d know that we challenge everyone to find the answers themselves. Transparency is a beautiful thing when you’re marketing supplements, especially when you know that you have nothing to hide.

You can only imagine my reaction when I came across a Facebook post from a well-known wellness clinic that links to an article that warns men about testosterone boosters, and why they don’t work. The article is published by one of the most popular health websites, and it surprises me that despite the traffic and popularity that this website gets, the article severely lacked the objectivity and accuracy that you’d expect from institutions that syndicate health information.

Don’t get me wrong. I’m not dismissing the fact that some testosterone boosters are downright dangerous and should be permanently banned, but there’s a far greater number of studies about natural testosterone-boosting ingredients that are safe and actually works to increase testosterone levels. The least they could have done is to look into these ingredients and objectively include the studies in their conclusions.

I have to tell you, I’m not surprised that a wellness clinic that offers testosterone replacement therapy (TRT) is sharing links that disparage testosterone boosters. It’s in their best interests to lure customers away from natural testosterone boosters since it destroys the legitimacy of the services that they offer.

It’s a lucrative business, mind you. I know guys who pay $300-400 every month to get their testosterone shots. These account for the tests, the drugs, and the additional therapy to prevent the drug’s side effects. What they don’t tell you is that once you start the treatment, you’re in it for life – or at least for as long as you want to have the benefits of testosterone. It’s a cycle that makes you dependent on the treatments to get the benefits and to avoid the side effects of the treatment itself. What’s sad is, you might not even need the treatment in the first place – but let’s hold that discussion for another day.

It’s true that no testosterone supplement – not even Male UltraCore, works as fast as testosterone shots to increase your testosterone levels, but the risks you take with these shots are far greater than premium testosterone-boosting supplements.


Let me tell you why.


Testosterone replacement therapy is well-known for its health risks and side effects. Doctors are required to warn their patients of the side effects of TRT before starting the treatment. The risks and side effects are well-defined in peer-reviewed journals and mind you[1]if every patient on TRT understood these risks, I’m quite sure that TRT wouldn’t be as popular as it is today.

It’s actually surprising that family doctors continue to initiate testosterone treatments for minor symptoms of age-related low testosterone for the benefit of improving energy, vitality, physical function, and cognition since the American College of Physicians specifically recommends against treating these symptoms with TRT[2].

On the other hand, testosterone-boosting supplements offer a safer, much more sensible way to restore your testosterone levels and increase your lean muscle mass, energy, and libido.


That’s why we created Male UltraCore.


Male UltraCore is a premium male performance-enhancing supplement that can help increase and sustain your testosterone levels, while simultaneously improving blood flow. Testosterone and blood flow are the two main factors that influence your physical and sexual performance, and to ensure that you get the results you need, we handpicked ingredients that are scientifically-proven to increase testosterone levels and vasodilation.

Ingredients like Longjack (Tongkat Ali/Eurycoma Longifolia), KSM-66 (Ashwagandha), Fenugreek, and ZMA (Zinc+Magnesium Aspartate) are among the most studied ingredients in the supplement business, and we got them all in one product, to give you the best results possible.

It won’t surprise me if you’ve heard of these ingredients, or if you’re already familiar with what these ingredients do. After all, these herbs have been used for centuries as the central medicinal herbs used in Indian Ayurveda and traditional Chinese medicine.

One of the best examples of a great testosterone-boosting ingredient is Longjack, also known as Tongkat Ali or Eurycoma longifolia. The effectiveness of Longjack is well-known in the industry. Some guys in the 90s even called it the Asian Viagra, because it has a strong erectogenic effect that stems from its potent testosterone-boosting capability.


Longjack is one of the most studied natural testosterone-boosting ingredients. Scientists have discovered that Longjack contains bioactive complex polypeptides, called eurypeptides[3], that influence the biosynthesis of different androgens.

A double-blind study was conducted to measure the effectiveness of Longjack, and the results were conclusive as far as its testosterone-boosting capability is concerned. Here’s more about the study that was published in the Andrologia peer-reviewed medical journal [4]

Standardized water-soluble extract of Eurycoma longifolia, Tongkat Ali, as testosterone booster for managing men with late-onset hypogonadism

76 of 320 patients suffering from late-onset hypogonadism (LOH) were given 200 mg of a standardized water-soluble extract of Tongkat Ali for 1 month. The Ageing Males’ Symptoms (AMS) according to the standardized rating scale and the serum testosterone concentration were taken.

 Results show that treatment of LOH patients with this Tongkat Ali extract significantly (P < 0.0001) improved the AMS score as well as the serum testosterone concentration. While before treatment only 10.5% of the patients did not show any complaint according to the AMS scale and 35.5% had normal testosterone levels, after the completed treatment 71.7% and 90.8% of the patients showed normal values, respectively. Thus, Tongkat Ali extract appears to be useful as a supplement in overcoming the symptoms of LOH and for the management of hypogonadism.


What does the study tell us?


The treatment for hypogonadism is TRT, and this study reinforces the idea that a small dose (200mg) of Longjack can be beneficial for those patients who suffer from hypogonadism. The direct impact of Longjack on the body’s total and free testosterone levels makes it one of the most effective testosterone-boosting agents that could be used as a supplement.

Another ingredient worth exploring is KSM-66 and Ashwagandha extracts which are clinically-studied to increase testosterone and muscle performance. Ashwagandha has been used in Ayurvedic medicine for centuries, and KSM-66 is the modern application of Ashwagandha; a more concentrated and more potent extract that enhances the herb’s effectiveness.

Clinical studies also confirm the effectiveness of KSM-66 in improving testosterone levels, muscle strength, and recovery through a randomized controlled trial [5]

In this study, 57 male subjects, age 18-50 years old, with little experience in resistance training were split into two groups, 29 subjects received the Ashwagandha treatment, and 28 received the placebo. The treatment group received 300mg of Ashwagandha daily. The subjects underwent resistance training for 8 weeks, and the measurements were taken at the end of week 8.

The results are as follows:

Compared to the placebo subjects, the group treated with ashwagandha had significantly greater increases in muscle strength on the bench-press exercise

(Placebo: 26.4 kg, 95% CI, 19.5, 33.3 vs. Ashwagandha: 46.0 kg, 95% CI 36.6, 55.5; p = 0.001)

(Placebo: 9.8 kg, 95% CI, 7.2,12.3 vs. Ashwagandha: 14.5 kg, 95 % CI, 10.8,18.2; p = 0.04)

significantly greater muscle size increase at the arms

(Placebo: 5.3 cm(2), 95% CI, 3.3,7.2 vs. Ashwagandha: 8.6 cm(2), 95% CI, 6.9,10.8; p = 0.01)

Chest size

(Placebo: 1.4 cm, 95% CI, 0.8, 2.0 vs. Ashwagandha: 3.3 cm, 95% CI, 2.6, 4.1; p < 0.001).

greater reduction of exercise-induced muscle damage as indicated by the stabilization of serum creatine kinase

(Placebo: 1307.5 U/L, 95% CI, 1202.8, 1412.1, vs. Ashwagandha: 1462.6 U/L, 95% CI, 1366.2, 1559.1; p = 0.03),

significantly greater increase in testosterone level

(Placebo: 18.0 ng/dL, 95% CI, -15.8, 51.8 vs. Ashwagandha: 96.2 ng/dL, 95% CI, 54.7, 137.5; p = 0.004),

and a significantly greater decrease in body fat percentage

(Placebo: 1.5%, 95% CI, 0.4%, 2.6% vs. Ashwagandha: 3.5%, 95% CI, 2.0%, 4.9%; p = 0.03).


This study, by far, outlines just how effective natural testosterone boosters can be, as this took into account a diverse group of males of different ages, all with minimal experience in resistance training. This study alone should put to rest any objections about the effectiveness of natural testosterone boosters in increasing testosterone and muscle performance.


Testosterone Booster Safety and Effectiveness


Regardless of how impressive the studies maybe, we shouldn’t gloss over the fact that some testosterone boosters are downright dangerous to your health. These are supplements that may be laced with drugs or compounds that aren’t supposed to be in health supplements.

Cheap products would do everything they can to reduce their production costs, even if it means that they would fill up their supplement capsules with ingredients that are the equivalent of sawdust.

It all boils down to the ingredients. High-quality ingredients and standardized extracts are what separates cheap and dangerous testosterone boosters from premium-quality testosterone-boosting supplements. All of these studies use standardized ingredients to accurately measure the level of purity and the number of active compounds present in each ingredient, relative to its dosage.

The best Longjack and KSM-66 come from Asia, the birthplace of traditional medicine and Ayurveda, where it has been used for centuries to treat a vast range of symptoms, and these are the exact ingredients used in Male UltraCore.

Each 4-capsule serving of Male UltraCore is power-packed with a total of 2800mgs of high-quality ingredients and standardized extracts, including 550mg of Longjack, and 300mg of KSM-66. Longjack and KSM-66 are just two of the 17 major ingredients in Male UltraCore, and these dosages are even higher than the controlled dosages used in the studies. You can be 100% confident that at these dosages, your results will be even greater than the ones described in the studies.

The next time you come across an article or a link that tells you that testosterone boosters don’t work, just brush it off. The proof is in the studies, and now you know why we always say – Don’t take our word for it. Do your research. Compare the labels. You know better.
