It used to be that a man knew his place in the world; he could be rugged, ruthless, and even a bit crude, but sadly those days are no more. Blame it on whatever you will, but the fact is the modern man is a sad, sorry sack of an excuse of his once masculine self.
He’s missing that cunning and aggressive edge that made him the alpha among all of the betas aimlessly meandering through life.
Well, the time has come for man to get back to his primeval roots, and unleash his inner Neanderthal.
What is Neanderthal?
Neanderthal is the latest ground-breaking supplement from Primeval Labs that supports natural testosterone production, enhances libido, and restores confidence. This collection of all natural ingredients have been precisely formulated to enhance and support testosterone production and help defend against estrogen conversion in the body.
Why Use a Test Booster?
Men’s testosterone levels peak at age 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 scientifically formulated to aid natural testosterone production and make you feel like the strong, virulent alpha male you used to be. While using Neanderthal, you may experience increased metabolism, superior lean mass gains, improved libido, and significantly greater energy levels. All of this can be accomplished by tapping into the synergism of 11 proven ingredients that will stimulate the production of testosterone and bring out the Neanderthal inside of you!
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
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 testosterone-boosting, stress-relieving benefits. Several scientific studies have shown maca to be successful for increasing libido, sexual desire, and even fertility. [5, 6]
On top of that, 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 notes that it can decrease prostate size.
Taken altogether, you can see why Maca is such a staple among Peruvians, and now you get to experience its benefits first hand in Neanderthal!
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 boosts 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 in the body [14, 15, 16], both of which benefit 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 supplementing 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.

Needed a natural/legal supplement, bought two bottles to give it a shot.... Been two weeks, taking the 4 caps twice a day rather than once, cuz unsure of the half-life, also because I'm 260lbs been a competing powerlifter for 20years and have doubts if product works. Will continue and post a second review after the 2nd bottle is consumed. Diet and training are on point, let's see if Neanderthal adds anything.
