Best Over The Counter Testosterone Booster Supplements Of 2023

Declining testosterone levels is something that most men have to deal with. As they get older, their T levels go down, leading to a reduced libido, loss of muscle mass, and weight gain. 

Procedures like Testosterone Replacement Therapy (TRT) can counter this decline. But, between doctor visits and prescribed medication, TRT can be both expensive and time-consuming. 

This is where over-the-counter testosterone boosters come in and offer to restore your T levels without a prescription. The question is, which T-boosting supplement should you trust with your time and money?

We dove deep into the world of testosterone boosters to find an answer and five options stood out to us. 

Here are our recommendations for the best over-the-counter T-boosting supplements in 2023.

1. TestoPrime

TestoPrime takes the number one spot on our list as it combines a rapid increase in testosterone levels with several general health benefits. What we especially like about this over-the-counter supplement is that it provides clear stats about its effectiveness. Here’s what it offers:
Quick Facts Overview
  • Average 44% increase in your testosterone production
  • A 71.6% reduction in physical and mental stress
  • Increased endurance by 92.2% to allow longer workouts
  • 16% faster elimination of excess body fat
  • Higher conversion rate of fat into energy by 12%
  • A drastic 138.7% muscle strength boost to support more intense workout sessions

After taking a closer look at its composition, we discovered that the primary ingredient behind its T-boosting benefits is D-Aspartic Acid (DAA). Other components that caught our attention include Green Tea extract and Panax Ginseng.

Among these, D-Aspartic Acid is one of the most effective. According to a 2009 study by Topo et al., DAA supplementation can boost your T levels by as much as 42% after just 12 days of use. 

The Green Tea in its formula acts as a fitness supplement and allows you to lose weight faster by accelerating fat oxidation. Simultaneously, Panax Ginseng provides several aphrodisiac benefits. A 2007 study by Andrade et al. shows that this herb can be used as a cure for erectile dysfunction.

2. TestoFuel

TestoFuel is an over-the-counter testosterone booster that can also double as a fitness supplement for many men. Its primary goal is to return your testosterone levels back to how they were in your youth. In addition to that, we also noticed several secondary benefits to assist your weight loss and muscle gain journey. These include:
Quick Facts Overview
  • Faster muscle growth with the same diet and workout routine
  • Higher body strength to allow more intense workouts
  • Faster fat elimination, especially from your stomach
  • Mood improvements so you can stay focused on your body shape goals
  • Increased self-esteem from better performance in the gym

A quick analysis of its composition tells us that Testofuel contains 10 different ingredients. The three most noteworthy among these for us are D-Aspartic Acid, Vitamin D, and Oyster extract.

For D-Aspartic Acid, the proof of its effectiveness at boosting T levels is a 2007 study by Antimo D'Aniello et al. This study shows a clear correlation between DAA supplementation and increased secretion of the luteinizing hormone. These hormones play a key role in testosterone production and increasing their concentration leads to higher T levels. 

Vitamin D, on the other hand, is known as a strength-increasing supplement. We found a 2012 study by Ogan et al. which demonstrated how higher Vitamin D levels were linked to boosted muscle strength and healthier bone growth. 

You can learn more about Testofuel from our thorough review of this supplement.

Magnesium (as Magnesium Oxide) - 70 mg

  • Returns testosterone levels lost with age

  • Suitable for both men and women
  • Increases your strength to allow more intense workout sessions


  • Not suitable for folks on a vegan or vegetarian diet
  • Its "four capsules a day" dose can cause digestive issues for some users

3. TestRX 

Similar to Testofuel, TestRX is also a prescription-free, over-the-counter testosterone booster with a clear focus on helping you build muscles. But, unlike Testofuel — which is for adult men of any age — TestRX puts more focus on older men that are past their prime. From our experience with this supplement, one of its key goals is to help men over the age of 40 regain their youthful virility. 

To achieve this, it boosts their T levels and offers the following secondary benefits:

Quick Facts Overview
  • Accelerated muscle growth
  • Increased energy levels
  • Boosted body strength
  • Faster weight loss and fat metabolism
  • Enhanced libido and performance

TestRX backs its promises with seven different ingredients. The ones that drew our attention are its three most abundant ingredients including D-Aspartic Acid, Fenugreek extract, and Magnesium.

We’ve already discussed the effectiveness of D-Aspartic Acid in previous products. But, another proof of benefits is a 2015 study by J. Bloomer et al. It tested the impact of regular DAA supplementation on ten men over the age of 42. And, after the 28-day test period, most participants showed a 20% increase in their T levels.

The Fenugreek in its formula can also boost your testosterone levels. We found a 2017 study by Maheshwari et al. which shows how Fenugreek consumption can increase T levels by 46% and also enhance libido in 12 weeks.

Lastly, a 2015 report by Maggio et al. demonstrated a direct correlation between higher Magnesium concentration and boosted T levels in 399 older (65+) men.

4. Primegenix Testodren

Testodren by Primegenix takes the fourth spot on our list of best over-the-counter T boosters because of its simplicity. It relies on only one ingredient to achieve its goals; Fenugreek. More specifically, it uses US-patented compounds found in the Fenugreek herb, also known as Trigonella foenum-graecum.

From our time with the supplement, these are the benefits you can expect from it:

Quick Facts Overview
  • Significantly higher testosterone levels
  • Improved mood and mental alertness
  • Boosted libido and sex drive
  • Increased body strength
  • Faster fat elimination

For Testodren, we took a deep dive into the scientifically-proven benefits of Fenugreek and discovered that it is as effective as this supplement claims it to be.

Arguably the most important research we found was a 2016 clinical report by Rao et al. It observed the impact of Fenugreek supplementation on 120 healthy men aged between 43 and 70 years of age. According to its report, most participants demonstrated significantly higher testosterone levels after 12 weeks of supplementation. 

An earlier 2010 study by Poole et al. also reported that regular Fenugreek consumption can increase your upper and lower body strength. This study also established a direct correlation between Fenugreek intake and lower body fat. Simultaneously, the 2017 study by Maheshwari et al. we mentioned earlier also showed how this herb can improve your mood, libido, and mental clarity.

Fenugreek (Trigonella foenum-graecum) - 500 mg


  • Convenient, one capsule a day dosage
  • Offers long-term boost in testosterone levels
  • Makes you feel more energetic and motivated
  • Revitalizes your libido and sexual performance
  • Its single-ingredient formula makes it easier to understand and trust


  • Not formulated for vegans or vegetarians

5. Testo-Max 

On paper, Testo-Max is an effective over-the-counter testosterone booster. But, in our experience, it behaves similarly to a fitness supplement. This is evident from its claim of being a safer alternative to Sustanon growth steroids. It offers all the benefits of these steroids without any of their side effects like acne, infertility, or erectile dysfunction. These benefits include:
Quick Facts Overview
  • Accelerated muscle gain without having to change your diet or workout routine
  • Helps your muscles recover faster after every workout session
  • Increased strength and stamina to allow more intense workouts
  • Improves the results of both cutting and bulking

After going through its list of ingredients, the ones that stood out to us as notable inclusions are D-Aspartic Acid, Korean Red Ginseng, and Nettle Leaf extract.

As we’ve mentioned before, D-Aspartic acid is one of the most effective T-boosting substances in most supplements. Its consumption boosts the secretion of the luteinizing hormone which, in turn, signals your testes to produce more testosterone. This correlation is proven repeatedly in the 1996, 2000, and 2007 studies by D'Aniello et al. 

As for Korean Ginseng, a 2018 study by M Arring et al. demonstrates that regular Ginseng supplements can boost your energy levels during the day. This herb is also an aphrodisiac that can revitalize your libido and reduce the symptoms of ED.

Lastly, the Nettle Leaf extract in Testo-Max prevents the conversion of free testosterone into estrogen. We found a 2007 study by E Chrubasik et al. which shows how Nettle extract achieves this by lowering the concentration of 5-alpha-reductase.

  • Helps you gain muscles and lose fat faster
  • Safe and effective alternative to Sustanon steroids
  • Improves your workout performance
  • Safe and natural composition
  • Boosts libido and improves sexual performance


  • Not vegan or vegetarian-friendly due to Gelatin capsule


The five testosterone boosters we’ve mentioned above are some of the most effective over-the-counter solutions to low T in 2023. You can choose any one of them and restore your T levels back to normal fairly quickly. 

But, if you’re having a hard time picking between them, focus on exactly what you want. For example, Testofuel, TestRX, and Testo-Max are all solid choices for men looking to gain some muscle and lose excess weight. 

Similarly, TestoPrime offers general health improvements alongside higher T levels, while Testodren offers a simple and to-the-point solution for hypogonadism.
