If you've noticed low energy, poor mood, decreased motivation, and struggle with losing fat and/or building muscle, it may be a good idea to assess your hormone health!

Manpower is a natural testosterone booster that's specifically formulated for anyone that wants to optimize their hormone levels.  Unlike other testosterone boosters, Manpower has a fully transparent label and uses several patented ingredients, such as Primavie® and Bioperine® to support your body's natural testosterone production.

Some of the primary benefits from taking Manpower include enhanced lean muscle mass, increased power and strength, improved endurance and stamina, and elevated libido and mood!

MANPOWER is our all-natural testosterone booster that was first released back in October of 2018. Although the original MANPOWER received phenomenal feedback, over the past three years, we found a way to make it even better!

Since MANPOWER is finally back in stock and features a new & improved formula, we decided that it would be the perfect time to give you hard working M’Fers a complete breakdown of MANPOWER!

Keep reading to learn more about MANPOWER’s ingredients, suggested use, and what products can be taken alongside it for even better results.

The Importance of Testosterone

Before we dive into the nitty gritty details of MANPOWER, let’s first cover the importance of testosterone and why you should consider using a natural testosterone supplement.

Testosterone is a hormone that’s present in both males and females. However, males have much higher testosterone levels than females, which is one of the main reasons why men are typically stronger, bigger, and have more masculine features. Not only is testosterone essential for overall health, but it plays an important role in energy levels, muscle mass, bone density, libido, mood, sense of well-being, and performance.

Various lifestyle factors can negatively impact testosterone levels, including high levels of body fat, lack of sleep, low physical activity, an unhealthy diet, and chronically elevated stress levels. Although the factors listed above can be addressed, one thing that impacts testosterone levels the most is age, which unfortunately cannot be reversed.

After age 30, a male’s natural testosterone production will begin to decline. Low levels of testosterone can lead to numerous issues, including:

  • Low libido (sex drive)
  • Depression
  • Low energy
  • Loss of muscle mass, strength, endurance, and stamina
  • And other serious health conditions

If you’re over the age of 30 and begin experiencing any symptoms of low testosterone, then it may be time to speak to a medical professional. If it turns out that you do have low testosterone levels, then you can consider using a natural testosterone boosting supplement, such as MANPOWER.

What Makes MANPOWER Different

Testosterone boosters are one of the most popular supplements on the market, but very few contain efficacious doses of ingredients that actually work. The vast majority of “natural” testosterone boosters are spiked with illegal ingredients that can be more harmful than helpful, while others are incredibly overpriced.

Similar to every other product we create, MANPOWER was developed because there was a clear need for a well-formulated, safe, and effective testosterone booster in the industry. So in 2018, we set the standard for how a natural testosterone booster should be formulated. Now, three years later, we’re raising the bar once again with the new & improved MANPOWER.

MANPOWER is a natural testosterone booster that’s specifically formulated for the hardest workers in the gym who want to optimize their hormone levels. Unlike other testosterone boosters, MANPOWER has a fully transparent label, no grey-market or illegal ingredients, and uses several patented ingredients for maximum effectiveness, such as PrimaVie® and BioPerine®. 

Here are some of the main benefits that you can expect from MANPOWER:

  • Enhanced lean muscle mass
  • Increased power & strength
  • Improved endurance & stamina
  • Elevated libido
  • Better mood & energy levels

How does MANPOWER achieve all of these benefits? Let’s dive into the formula to find out!

  • Tribulus Terrestris Extract (350 mg, std. 40% Saponins)

    Traditionally used to support libido and vitality. The saponins may modestly influence testosterone but evidence in humans is mixed.

  • Mucuna Pruriens Extract (350 mg, std. 15% L-Dopa)

    Source of L-Dopa, which can support dopamine production. Sometimes linked to improved mood, fertility, and hormone balance.

  • Fenugreek Extract (300 mg, std. 50% Saponins)

    Popular for supporting testosterone, libido, and blood sugar balance. Some studies show mild improvements in testosterone and body composition.

  • Safed Musli Extract (250 mg, std. 50% Saponins)

    Traditional Ayurvedic herb used for strength, energy, and male vitality. Limited modern studies, but historically valued as an adaptogen.

  • Shilajit (Primavie®, 250 mg, std. 50% Fulvic Acid)

    A mineral-rich resin. Shown in some trials to support free testosterone levels and energy. Branded form (Primavie®) ensures standardized quality.

  • Longjack (Tongkat Ali) Extract 100:1 (150 mg)

    Known for boosting libido, reducing stress hormones (like cortisol), and potentially raising free testosterone.

  • Maca Powder (150 mg)

    Peruvian root used for energy, mood, and sexual health. Evidence supports improved libido more than direct testosterone increase.

Other Key Compounds

  • 3,3’-Diindolylmethane (DIM, 100 mg)

    Derived from cruciferous vegetables (like broccoli). Helps regulate estrogen metabolism, often used to support a better testosterone-to-estrogen balance.

  • Black Pepper Extract (10 mg, BioPerine®)

    Enhances absorption and bioavailability of the other ingredients, making the formula more effective.

How it Works (Synergy)

  • Testosterone Support → Tribulus, Fenugreek, Shilajit, Longjack.

  • Libido & Vitality → Mucuna, Maca, Safed Musli.

  • Hormone Balance → DIM helps reduce estrogen dominance.

  • Absorption → Black pepper extract ensures higher uptake of actives.
