Primeval Labs Neanderthal is an all-natural testosterone support matrix scientifically formulated to reduce stress, boost energy levels, restore confidence, and support a healthy hormone profile.
Men’s testosterone levels peak at ages 25-30, and then it’s a steady decline into the gloomy realm of low testosterone, and with that comes decreased energy, libido, mood, and muscle mass. But, your fate doesn’t have to be one of doom and gloom.
Neanderthal has been meticulously engineered to support natural testosterone production and hormone homeostasis. When taking Neanderthal, you may experience increased energy levels, better recovery, enhanced libido, and greater mood.
Here’s a look inside Neanderthal…
Sensoril Ashwagandha (750mg)
Many know cortisol has the stress hormone. When you get stressed, you have trouble sleeping, feel hungrier, and generally are more on edge. While all this sounds pretty unsettling, what’s worse is that when you’re chronically stressed, your testosterone production is also negatively impacted.
Ashwagandha is an incredibly popular adaptogenic herb widely used in Ayurveda most notably for its ability to improve the way your body reacts, processes, and adapts to stress.
In addition to its ability to ameliorate stress , ashwagandha has been shown in research to boost production of several important man-making hormones including Luteinizing Hormone (LH) and Testosterone.  This powerful herb also has been documented to reduce Follicle Stimulating Hormone (FSH) levels, which improves semen quality in men. 
Neanderthal includes the premier form of Ashwagandha in Sensori at a whopping 750mg dose per serving! Sensoril is a premium quality form as ashwagandha standardized for 8% Withanolides and has been shown in research trials to significantly reduce :
- Fasting blood sugar
- C-reactive protein
Additionally, studies using Sensoril have noted that it can also significantly increase levels of DHEA, one of the most important hormones in the body that helps produce other hormones, including testosterone. DHEA may also combat the effects of aging, improve mood, and support overall health and wellness. 
Maca Powder (400mg)
Long used by the natives of Peru as an aphrodisiac, Maca is a plant frequently supplemented for its libido-enhancing, stress-relieving benefits. Several scientific studies have shown maca to be successful for increasing libido, sexual desire, and even fertility. [5, 6]
Maca is also a potent adaptogen, which will help to combat stress and may yield some benefits in regards to increased performance, learning, and memory.  Some animal research even suggests it may decrease prostate size.
For centuries, fenugreek has been a staple component of Ayurveda where it was used to enhance testosterone production and libido and improve glucose metabolism. These days, fenugreek is a frequent inclusion in natural testosterone boosters and muscle builders due to its actions as an alpha-5 reductase inhibitor, which may prevent testosterone from being converted to DHT (dihydrotestosterone). [8 ,9, 10]
In theory, this may lead to increased testosterone levels as well as a decrease in body fat.
Additional research has also noted that fenugreek supplementation also can lead to increase in strength and lean body mass, suggesting that not only is fenugreek a formidable natural testosterone support ingredient, but also a powerful performance enhancing supplement as well. 
Neanderthal includes a premium-quality fenugreek extract standardized for 50% saponins, powerful phytochemical naturally-occurring in the plant that are responsible for its litany of benefits.
Eurycoma Longifolia (Longjack) has a rather long and storied track record as a potent aphrodisiac, used for centuries in eastern cultures for its libido-enhancing properties.
Longjack has been well-documented to support hormone regulation, enhance erection quality, and delay ejaculation. [9, 10, 11] In other words, longjack may help you last longer in bed!
On top of that, Longjack also has been shown to exert some anti-estrogen effects, which promotes an environment prime for natural muscle building and recovery. [12, 13]
Perhaps the greatest upside to longjack supplementation, and the primary reason we included it in Neanderthal, is based upon research documenting that the all natural herb significantly increases free testosterone levels, total testosterone levels, and force production! [14, 15, 16]
One last thing that should be mentioned about longjack is that it helps reduce cortisol levels and may even help reduce estrogen expression[14, 15, 16], both of which support natural testosterone production as well as your ability to build lean, hard muscle mass!
Boron is an essential trace mineral that’s necessary for overall health and optimal function. It’s vital for bone growth, but research has revealed the mighty mineral also plays an extremely important in the body’s ability to produce testosterone. In fact, studies have shown that supplementation with 10mg boron (the same dose used in Neanderthal!) significantly increases free testosterone levels by 28% and decreases estradiol (a form of estrogen) by 39% after only seven days of use! [17, 18]
Boron is also beneficial for bone maintenance, cognition, learning, and many other things , which is why you never want to be lacking in this essential mineral.
Neanderthal uses the highly bioavailable form of supplemental boron in Bororganic, a trademarked complex of boron glycinate. Using this enhanced form of boron helps ensure optimal absorption and utilization for your body.
For best results, consume one serving (i.e. four capsules) daily.
