Best Testosterone Boosters in 2023

  1. Testo Prime - Best All-Around
  2. Testogen - Best for Energy
  3. Prime Male - Best for Libido
  4. Testofuel - Best for Vitality
  5. Testo-Max - Increase Muscle Mass

1. TestoPrime - Top Rated Testosterone Booster

A product designed for the middle aged man, TestoPrime is a testosterone booster manufactured by the UK-based beauty and wellness company Wolfson Brands. Made from a dozen ingredients, it claims to improve levels of free testosterone in users by up to 44 percent.

As a result of the testosterone gains, TestoPrime promises noticeable improvements in physique, lean muscle mass, physical strength, stamina, vivacity, energy, weight loss, injury recovery, sleep quality, mental focus and sex drive. You get an energy surge at day’s end despite engaging in physically and mentally exhausting tasks.

Specifically, the product purports to:

  • Increase muscle strength by up to 138.7%.
  • Increase fat metabolism by up to 12%.
  • Improve fat burning by up to 16%.
  • Increase endurance by up to 92.2%.
  • Reduce stress levels by as much as 71.6%. It suppresses the stress-related hormone cortisol’s production. 

These benefits ride on the efficacy of TestoPrime’s individual ingredients. For example, it contains d-aspartic acid (D-AA). D-AA is the anchor ingredient in many testosterone supplements including our top five. It has been proven to improve testosterone levels by up to 45% in the first two weeks and up to 60% in the first three months. D-AA supports protein synthesis as well which is essential for muscle growth, physical strength and injury recovery.

TestoPrime contains fenugreek seed extract. This herb has broad benefits spanning testosterone production, metabolism, fat loss, rest, energy and sexual health.

Prices

A bottle of TestoPrime costs $59.99 and contains 120 pills to last 30 days. You get a price discount on orders of two or more bottles. There’s free worldwide shipping on all orders. Unusual for the industry, TestoPrime has a bold lifetime money back guarantee.

2. TestoGen

A product of the prolific supplement maker Health Nutrition Limited, TestoGen is a testosterone booster manufactured from nearly a dozen clinically proven, natural ingredients. It claims to reverse the symptoms of low testosterone. Other benefits of the product include improvements in muscle mass, fat loss, energy, vitality, sex drive and thought clarity. Introduced to the market in 2004, TestoGen has drawn in excess of 100,000 buyers.

Like other testosterone supplements, TestoGen is available in pill form. It however stands out for the availability of oral drops. TestoGen drops are meant to make it to your bloodstream much quicker than pills. That results in a quicker boost to testosterone levels. The drops are best suited for situations where a rapid testosterone surge is required such as a long day at work, early morning and late night activities as well as pre-workout sessions. TestoGen oral drops complement TestoGen pills and are to be used in tandem and not as a substitute.

TestoGen’s efficacy comes down to the blend of 11 ingredients. It has the largest amount of D-AA and magnesium per serving in our top five. Magnesium is a crucial micronutrient with benefits encompassing testosterone production, metabolism, muscle function, strength, injury recovery, endurance and rest. TestoGen has sizable quantities of fenugreek as well.

  • Enhances sex drive, physical/energy levels and vitality.
  • Available not just in traditional pill form but oral drops too. Drops are absorbed quicker leading to a quick rise in testosterone levels.
  • Made in GMP-compliant, FDA-registered facilities in the UK and US.

Cons

  • The claim that TestoGen reverses symptoms of low testosterone has not been unproven.

Prices

3. Prime Male

Made by UK-based Roar Ambition, Prime Male Vitality Complex (or simply Prime Male as it is more widely known) is one of most recognizable brands in the testosterone supplement industry. It aims to boost free testosterone levels of middle aged and elderly men by 42% in 12 days. 

Blending a dozen clinically proven, natural ingredients, its main path of action is regulating four testosterone-affecting hormones – estrogen, luteinizing hormone (LH), luteotropin and sex hormone binding globulin (SHBG). From the resulting testosterone boost, Prime Male purports to improve muscle mass, strength, bone density, thought clarity and self-belief. It also has benefits on fat loss (including stubborn tummy fat) and endurance.

Prime Male claims to mitigate symptoms of low testosterone like blood sugar imbalances, high blood pressure, cardiovascular illness, mood swing and depression.

It comes down to the supplement’s ingredient mix. Prime Male may have the lowest amount of the super-ingredient D-AA in our top five but it makes up for that with the highest quantity of ashwagandha, stinging nettle and panax ginseng per serving on the list. 

Ashwagandha is an ayurvedic herb whose root has adaptogenic, antioxidant traits shown to support sexual health and testosterone production. Stinging nettle’s leaf has compounds that block SHBG from attaching to testosterone as this would reduce amounts of free testosterone. Panax ginseng is a herbaceous plant that studies show increases testosterone levels, regulates dopamine and revives libido.

There is no money back guarantee but you can get a refund on bottles returned unopened and undamaged within 30 days from the date of purchase (US orders) and 14 days (other countries).

4. TestoFuel

Manufactured by Roar Ambition, TestoFuel is a testosterone supplement that claims to grow lean muscle bulk by increasing your testosterone level. Whereas it can be used by men of all ages, it is best suited for older men keen on regaining the vitality of their youth. 

Its primary path of action is muscle protein synthesis that ensures the body gets the components required to increase muscle. Other benefits that TestoFuel promises include physical strength, fat loss, motivation, self-belief and a positive mood. It purports to regulate blood glucose and insulin both of which are critical for weight loss.

TestoFuel derives its power from the efficacy of the 10 key ingredients it’s composed of. It contains D-AA and panax ginseng but also maca and oyster. The maca herb’s root contains compounds known to enhance libido, stamina, rest and mood. Oyster has been used in alternative medicine as an aphrodisiac for centuries, something modern research has confirmed. It contains unusually high amounts of zinc which drives its capabilities in improving testosterone production, sexual health and sex drive.

The individual capabilities of Testo-Max’s 11 ingredients are the cornerstone of its efficacy. It has the largest amount of D-AA and magnesium per serving in our top five. Testo-Max has sizable amounts of fenugreek, panax ginseng and stinging nettle as well. Importantly, it contains zinc, a micronutrient that’s central to sexual health

Talk to your doctor to determine what solution or product would be best for you in the context of your overall state of health.
