Testosterone is the primary anabolic hormone in males and plays a crucial role in a male’s reproductive health. However, testosterone also significantly impacts a male’s energy levels, ability to build muscle mass, gain strength, and maintain bone mass. So having an adequate level of testosterone can make a huge difference in a male’s physique, quality of life, 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 testosterone production will naturally begin to decline. Low levels of testosterone can lead to fatigue, reproductive problems, weakness, depression, and other serious health conditions. If you’re experiencing any symptoms of low testosterone, then it may be time to speak to a medical professional and consider using a natural testosterone boosting supplement.

Testosterone boosters are one of the most popular supplements on the market, but few contain efficacious doses of ingredients that actually work. Fortunately, Axe & Sledge has formulated a natural testosterone booster with nine ingredients that are scientifically proven to support testosterone production.

Ingredient Breakdown

Tribulus Terrestris

Tribulus terrestris extract is a plant that’s commonly used in ancient medicine to treat low libido, infertility, and erectile dysfunction. Tribulus terrestis is rich in several bioactive compounds, including alkaloids and saponins.

Since saponins are largely attributed to their ability to boost testosterone levels and libido, MANPOWER uses an extract that’s standardized to contain at least 40% saponins. Other beneficial properties that tribulus terrestris offers include anti-inflammatory, hepatoprotective, antidiabetic, antibacterial, and anticancer.

Mucuna Pruriens

Mucuna pruriens extract is a bean that’s a rich source of L-dopa (also known as levodopa). As the name suggests, L-dopa is a precursor to dopamine, a neurotransmitter that contributes to well-being, feelings of pleasure, mood, motivation, movement, and memory.

Since mucuna pruriens contains a high amount of L-dopa, supplementing with it may help increase testosterone, dopamine, luteinizing hormone, norepinephrine, and epinephrine levels.


Similar to tribulus terrestris, fenugreek seed extract, also known as Trigonella foenum-graecum, is also rich in saponins. By inhibiting two enzymes — aromatase and 5-alpha reductase — fenugreek is able to increase free testosterone levels by blocking its conversion to dihydrotestosterone (DHT) and estrogen.

This boost in testosterone can lead to an increase in strength, muscle mass, energy, libido, body composition, and mood. Supplementing with fenugreek may also positively affect blood lipid levels and insulin sensitivity.

Safed Musli

Safed musli extract, also known as chlorophytum borivilianum, is a herb that’s been historically used to treat sexual disorders, promote men’s health, and as an adaptogen. In other words, safed musli helps users adapt to and overcome emotional and physical stress.

Similar to fenugreek and tribulus, safed musli is also rich in saponins. Supplementing with safed musli may improve testosterone levels. Safed musli expresses other beneficial properties such as anti-stress, antioxidant, aphrodisiac, and immunomodulatory. 


PrimaVie® is a high-quality, clinically studied, purified Shilajit extract that was developed by Natreon. PrimaVie® is derived from the Himalayas and contains a high amount of dibenzo-alpha-pyrones (DBPs), DBP-Chromoproteins (DCP), fulvic acid, and over 40 minerals. Shilajit has been used for centuries and is considered to be the ideal anti-aging supplement.

Supplementing with PrimaVie® may support male sexual health, increase energy production, boost exercise endurance and overall fitness, up-regulate collagen synthesis and steroidogenic gene expression, and enhance the absorption of CoQ10. Not to mention, PrimaVie® is vegetarian, Kosher and Halal certified, self-affirmed GRAS (generally recognized as safe and protected by multiple patents.


Longjack extract, also known as Eurycoma longifolia root, is a plant that contains several beneficial constituents, such as alkaloids, tannins, triterpenes, quassinoids, and phenolic compounds. Due to its rich phytochemistry, longjack root expresses powerful antioxidant, aphrodisiac, anticancer, anxiolytic, and antibacterial properties.

Longjack is commonly used as a natural alternative for testosterone replacement therapy because of its unique ability to stimulate the production of androgenic hormones, such as testosterone. Some evidence even suggests that longjack can improve exercise performance by acting as an ergogenic aid. 

Maca Powder

Lepidium meyenii root, more commonly known as maca powder, is a plant that offers numerous health benefits. Supplementing with maca may improve mood, cognition, libido, and male infertility. Furthermore, maca has been shown to enhance exercise performance by increasing strength, endurance, and stamina, while reducing fatigue and lactic acid levels.

3’3’-Diindolylmethane (DIM)

3'3'-Diindolylmethane, or DIM for short, is a chemical compound that’s produced by the body from the metabolism of indole-3-carbinol (I3C), which is naturally found in cruciferous vegetables. DIM is known for its ability to decrease the production of “bad estrogen” (16-alpha-hydroxyestrone) and increase the production of “good estrogen” (estradiol-2-hydroxylase).

Moreover, DIM is capable of inhibiting aromatase, an enzyme that converts testosterone to estrogen, and 5-alpha-reductase, an enzyme that converts testosterone to dihydrotestosterone (DHT). DHT is known for causing male-pattern baldness, which no one wants. So keeping DHT levels low is ideal. In summary, supplementing with DIM will help keep your estrogen and testosterone levels in check.


BioPerine® is a high-quality black pepper fruit extract, also known as piper nigrum, developed by Sabinsa Corporation. The main bioactive consistent that’s attributed to BioPerine®’s benefits is piperine and it’s standardized to contain at least 95%.

Through various mechanisms of action, BioPerine® significantly improves the bioavailability and absorption of several ingredients in MANPOWER. This helps enhance the effectiveness of the product so you can get the most out of it!
