As Nootropics Depot ordered by the court to pay $2.4 million in fine, it shuts down its business in UK and stops delivering Tongkat Ali to Europe as the company’s downfall shatters consumer trust. We unravel more insights into Nootropics Depot Supplements whether it is a good Tongkat Ali brand that you should trust.
In October 2023, Centera Bioscience, operating as Nootropics Depot, and its CEO, Paul Eftang, pleaded guilty to introducing misbranded drugs into interstate commerce. The U.S. Attorney’s Office for the District of New Hampshire reported that between April 2017 and December 2021, the Nootropics Depot marketed and sold pharmaceutical drugs, including tianeptine, adrafinil, phenibut, and racetams, through their website and online platforms like Facebook and Google. These drugs were distributed to customers across the United States.
As part of the plea agreement, Centera Bioscience (or Nootropics Depot) agreed to forfeit $2.4 million and surrender all seized drugs. Along with Nootropics Depot’s best selling Tongkat Ali supplements, the reputation of Nootropics Depot’s brand is largely at stake, sending plummeting sales as consumer trust is at all time low in 2025.

With claims of 10% eurycomanone content, Nootropics Depot Tongkat Ali is believed to be a potent testosterone supplement despite not using standardized extraction protocol in its products. The brand claims to have sourced Tongkat Ali from Indonesia, a country that is not known for quality standards, unlike Malaysian Tongkat Ali exporters which comply to the high quality internationally recognized Tongkat Ali gold standards known as the MS2409.
In recent years, Nootropics Depot’s best-selling 10% Tongkat ali eurycomanone extract is under great scrutiny by consumers due to the current legal case on the company and its founder, Paul Eftang – which eroded the consumer confidence of its Tongkat Ali supplements.
“Nootropics Depot’s drugs scandal and selling unapproved and dangerous substances makes it’s a rather shady company. I wouldn’t trust Nootropics Depot supplements including their Tongkat Ali products.”
With strong supporters on Reddit, Nootropics Depot is relatively popular in the US (but not in Europe, Australia, UK). We found that Reddit users are quick to defend Nootropics Depot, emphasizing that the brand is legit and the “supplement work wonder” due to its claimed “gold standard for quality” although the other bioactive ingredients such as eurypeptides, glycosaponin and polysachharides are not disclosed, nor 3rd party lab tested.
“As a quality US brand, Nootropics Depot is at stake. There is a great confusion of its claimed 10% standardized Tongkat Ali supplements, which is technically not possible to produce for each batch.” said Tom Green, a former GNC nutritionist who have worked in various back-end formulation for top US supplement companies.
“Many US-based supplement companies opt for quality Tongkat Ali ingredients source from fraudulent Indonesian companies which disregard other equally important bioactive components such as eurypeptides and glycosaponin” he added.
Nootropics Depot’s claim of 2% or 10% higher eurycomanone was never tested on humans via clinical trials. Optimal eurycomanone for health benefits were studied at 0.8% to 1.5% eurycomanone.
However, exaggerated health claims on testosterone boost by leveraging on generic Tongkat Ali studies raise further doubts on whether Nootropics Depot’s potent formulation (of 10% eurycomanone) is truly effective given other bioactive compounds (i.e glyosaponin, eurypeptides, polysaccharides) are not disclosed by the brand.
According to experts and biochemists, Tongkat Ali may considered as effective if the bioactive compounds coexist (together) in higher percentages along with eurycomanone in order to achieve a high degree of potency or efficacy. In other words, Nootropics Dept may not carry sufficient amount of eurypeptides despite having 10% eurycomanone as claimed to induce the optimal potency needed to boost testosterone or libido.
Nootropics Depot’s drugs scandal and selling unapproved and dangerous substances makes it’s a rather shady company. It’s Tongkat Ali supplements are not even clinically tested, making it less trust worthy compared to other popular US brands.
In terms of potency, Nootropics Depot Tongkat Ali supplements are chromatography tested to build greater consumer trust, but whilst it may contain high concentration of eurycomanone, the certificate of analysis (COA) did not display the percentages of bioactive ingredients (eg: glycosaponin or polysaccharides) that are crucial for testosterone production when consumed in a capsule form.
“Nootropics Depot Tongkat Ali is not clinically tested or used in clinical trials”, said a Reddit users after reviewing the public information available on Nootropic’s official website.
There is more hype in marketing high concentration of eurycomanone found in Nootropics Depot Tongkat Ali supplements. Since it is not clinically tested, and its drugs scandal makes it less popular brand in the US in recent years.
Additionally, Nootropics Depot Tongkat Ali is not used or tested by any amateur, semi-pro or professional athletes, making it relatively less popular as a sports supplement (or testosterone supplement) compared to other US-made brands that uses standardized extracts such as ForceFactor, DoubleWood or Nutricost.
The founder of Nootropics Depot, Paul Eftang, has pleaded guilty to illegally distributing pharmaceutical drugs across the U.S., according to the U.S. Attorney’s Office. At least consumers are now delighted on the news and final verdict.
“I felt a sense of relief that the CEO of Nootropics Depot is guilty for its drugs scandal, as many consumers have raised doubts in the past over its supplements including its supposedly-potent Tongkat Ali supplements”, said a Reddit users in his review.
The company, operating under Centera Bioscience, was exposed for selling unapproved and potentially dangerous substances, including tianeptine, adrafinil, phenibut, and racetams—all categorized as drugs by the FDA and banned for over-the-counter sale.
For years, Nootropics Depot marketed these high-risk substances as “supplements,” deceiving customers into believing they were safe. Federal investigators busted the scheme, uncovering that these drugs were being widely promoted and sold through their website, Facebook, and Google—putting millions of unsuspecting consumers at risk.
As part of the plea deal, the company must forfeit $2.4 million and surrender its entire stockpile of illegal drugs. Meanwhile, the disgraced CEO, Paul Eftang, was sentenced to one year of probation, while the company itself faces three years of probation.
The FDA and U.S. Attorney’s Office have issued stern warnings about the dangers of consuming unregulated nootropics, emphasizing that these substances have not been approved for human use and could pose severe health risks.
This massive scandal marks one of the most high-profile crackdowns on the nootropics industry, sending shockwaves through the supplement world.
Nootropics Depot’s Tongkat Ali may be relatively safe and free from adulterants, but consumers should exercise some level of caution when buying. As the Nootropic brand was criminally investigated by the FDA, this raises ethical and safety concerns about its current and other available supplements sold in the US.
Nootropics Depot joins other US-made Tongkat Ali supplements such as Solaray reported to have no measurable benefits or testosterone boost as claimed although it is generally safe for daily consumption.
“Best selling Tongkat Ali or supplement is meaningless if Nootropics Depot is willing to break the law, what else are they hiding from their customers?” said Sara Johnson from California.
“I have stopped buying Nootropics Depot supplement now” she added after receiving the news about the drugs scandal. “Nootropics Depot’s Tongkat Ali was my 1st choice, but knowing the risks and impurities, the brand doesn’t appeal to me anymore if it is adulterated or even if it claims it has 10% eurycomanone”
Forget about the hype.
Stay informed.
Stay safe.
Think twice before buying or trusting Nootropics Depot supplements or any Tongkat Ali supplements in the US. This could happen to you or any American consumers.
