Published clinical evidence for the herb at the heart of EloMaas.
Last Updated: March 30, 2026 · Medically Reviewed by Dr. Marcus Webb, MD
Tongkat Ali (Eurycoma longifolia) is a flowering plant native to Southeast Asia that has been used for centuries in traditional Malaysian medicine as a male vitality tonic. Unlike many traditional remedies that lack modern validation, Tongkat Ali has accumulated a substantial body of clinical research supporting its effects on testosterone, cortisol, libido, and male reproductive health. A landmark randomized controlled trial (PMID: 23243445) published in the Journal of the International Society of Sports Nutrition documented significant increases in testosterone and decreases in cortisol in supplemented subjects compared to placebo.
The mechanism is multi-faceted. Tongkat Ali appears to support testosterone production through several pathways: enhancing the release of luteinizing hormone (LH) from the pituitary, which signals the Leydig cells in the testes to produce more testosterone; reducing sex hormone-binding globulin (SHBG), which frees more testosterone for biological use; and lowering cortisol, the stress hormone that directly competes with testosterone at the production level. This triple action — more production, more availability, less suppression — makes Tongkat Ali uniquely comprehensive among natural testosterone supporters.
Testosterone and cortisol: Randomized, double-blind, placebo-controlled trial. Subjects receiving Tongkat Ali extract showed significant improvements in testosterone/cortisol ratio compared to placebo. Tension, anger, and confusion mood states also improved. Male reproductive health (PMID: 21195829): A study in the Asian Journal of Andrology found Tongkat Ali supplementation improved sperm quality and reproductive hormone profiles in men with idiopathic infertility. Stress and mood: The same sports nutrition trial documented improved stress hormone profiles and mood states, suggesting Tongkat Ali's benefits extend beyond pure testosterone support into stress resilience and emotional wellbeing.
In EloMaas, Tongkat Ali serves as the primary testosterone-supporting ingredient. Its cortisol-lowering effect creates the hormonal environment where the other ingredients can function optimally. Lower cortisol means less testosterone suppression, which means L-Arginine's improved blood flow is carrying more testosterone to target tissues. Lower cortisol also improves sleep quality, which supports overnight recovery and growth hormone release. The stress-management benefits improve mental clarity and emotional resilience, reducing the anxiety that often accompanies bedroom performance concerns. Every effect Tongkat Ali produces amplifies the effects of the five companion ingredients.
The clinical evidence for Tongkat Ali continues to grow. New studies are investigating its effects on body composition, physical performance, and aging-related hormonal decline. The existing evidence base — particularly the randomized controlled data on testosterone, cortisol, and reproductive health — already positions it as the most credible natural testosterone supporter available. In EloMaas, it's paired with L-Arginine for blood flow, Maca and Tribulus for complementary hormonal support, Milk Thistle for liver protection, and Maqui Berry for antioxidant defense. The comparison with single-ingredient alternatives isn't close. Order from the official website with the 90-day guarantee to experience the research-backed results.
The natural testosterone support category includes dozens of botanicals: ashwagandha, fenugreek, D-aspartic acid, boron, zinc, DHEA, and many others. Most have limited, inconsistent, or methodologically weak evidence. Tongkat Ali stands out because it has randomized, controlled, published clinical trial data specifically documenting testosterone increases, cortisol reduction, and reproductive health improvements in human subjects — not just animal models or in-vitro cell studies. For the evidence-driven consumer evaluating which ingredient to trust, this clinical pedigree matters enormously.
In EloMaas, Tongkat Ali is paired with five complementary compounds that amplify its effects through three coordinated pathways. L-Arginine boosts the nitric oxide that delivers Tongkat Ali-supported testosterone more efficiently. Maca Root adds libido support through non-hormonal pathways. Tribulus provides additional LH signaling support. Milk Thistle protects the liver that metabolizes the hormones. And Maqui Berry defends the Leydig cells that produce them. The result is a formula where Tongkat Ali's testosterone support is amplified, delivered, utilized, and sustained more effectively than it could be as a standalone ingredient.
The clinical evidence for Tongkat Ali continues to accumulate. As the most studied natural testosterone supporter with human clinical trial data, it represents the gold standard for men seeking evidence-based hormonal optimization. In EloMaas, it's the foundation. In the broader supplement market, it's the benchmark. The 90-day guarantee lets you experience the research-backed effects with your own hormones. 14,000+ users confirm the translation from published data to personal results.
The clinical evidence on Tongkat Ali has direct practical implications. For men experiencing reduced libido: the testosterone and cortisol data suggest Tongkat Ali can help restore desire through hormonal rebalancing. For men with erectile concerns: improved testosterone supports sexual function, and reduced cortisol removes a major psychological barrier (performance anxiety). For men seeking muscle development: testosterone is the master driver of protein synthesis, and cortisol is its primary antagonist. Tongkat Ali addresses both sides of this equation simultaneously.
In EloMaas, Tongkat Ali's effects are amplified by five companion ingredients. L-Arginine provides the blood flow that delivers Tongkat Ali-supported testosterone more efficiently. Maca Root adds libido support through non-hormonal pathways. Tribulus provides additional LH signaling. Milk Thistle ensures the liver processing these hormones runs optimally. Maqui Berry protects the Leydig cells producing them. The result: a formula where clinical-grade Tongkat Ali is not just included but systematically amplified for maximum real-world impact.
For the evidence-driven consumer evaluating natural testosterone options in 2026: the question isn't whether Tongkat Ali works (the clinical data is clear). The question is whether it's delivered at effective doses, in a formula that amplifies its effects, with a guarantee that covers the evaluation period. EloMaas checks every box. The 90-day guarantee converts the published evidence into a personal, zero-risk experiment. 14,000+ men have run the experiment. 4.9 stars is the result.
Tongkat Ali has been consumed in traditional medicine for centuries, and modern clinical trials consistently report a favorable safety profile. The controlled trials documented no significant adverse effects compared to placebo. The compound is generally well-tolerated at recommended supplemental doses. However, men taking blood pressure medication, blood thinners, or hormonal therapies should consult their physician before use, as the testosterone-supporting and cortisol-reducing effects could interact with these medications. This caution applies to Tongkat Ali specifically and to EloMaas as a whole.
The distinction between Tongkat Ali and synthetic testosterone is critical for safety. Synthetic TRT introduces external hormones that suppress natural production, creating dependency. Tongkat Ali supports natural production without suppression — your body continues making its own testosterone, just more efficiently. This means you can stop taking Tongkat Ali (or EloMaas) at any time without withdrawal, hormonal crash, or dependency. Your natural production doesn't shut down because it was never replaced — only supported. This fundamental safety advantage is why the natural optimization approach through herbal compounds like Tongkat Ali is preferred by men who want results without lifelong pharmaceutical commitment.
EloMaas represents the convergence of traditional herbal wisdom and modern clinical validation. Each of the six ingredients has centuries of traditional use for male vitality, validated by contemporary research methodologies including randomized controlled trials and systematic reviews. This dual evidence base — historical and clinical — provides confidence that the formula works through real biological mechanisms, not marketing hype. The 90-day guarantee converts this evidence into a personal, zero-risk experiment with your own hormones. 14,000+ men have completed that experiment successfully. 4.9 stars is the aggregate outcome.
