DHEA is banned by WADA, but ProtoTest offers a compliant solution. This 50% protodioscin extract from Dioscorea nipponica naturally boosts DHEA production without the regulatory risks. Better standardization than tribulus, easier manufacturing, same hormone benefits.
The 2025 World Anti-Doping Agency (WADA) prohibited substances list makes it crystal clear: DHEA is banned for all competitive athletes, military personnel, and anyone subject to drug testing protocols.[1] Listed under anabolic androgenic steroids as "Prasterone (dehydroepiandrosterone, DHEA, 3ß-hydroxyandrost-5-en-17-one)", DHEA carries harsh penalties as a non-specified substance prohibited at all times - both in and out of competition.
DHEA clearly has legitimate benefits for hormone optimization, vitality, and athletic performance -- especially as you get older. The solution isn't abandoning these benefits altogether - it's finding a smarter, more compliant pathway to achieve them.
Enter ProtoTest, a Dioscorea nipponica root extract standardized to 50% protodioscin from Aura Scientific. This innovative ingredient offers a compliance-friendly approach to naturally boosting DHEA production without running afoul of testing protocols.
The Manufacturing Nightmare: Why DHEA Creates Problems Beyond Compliance
Beyond the obvious regulatory issues, DHEA presents significant manufacturing challenges that make it problematic even for non-tested consumers. DHEA is notoriously "sticky" during the manufacturing process, leading to cross-contamination issues that can affect entire production facilities.
This stickiness means that even products not intended to contain DHEA can become contaminated during manufacturing, creating compliance nightmares for brands serving multiple markets. For companies that produce both consumer supplements and products for tested athletes, DHEA contamination represents an unacceptable risk.
The manufacturing complications extend to formulation challenges as well. DHEA's properties often require tablets, larger capsule counts, or specialized processing techniques, driving up costs and reducing consumer convenience.
Ultimately, many manufacturers simply don't want to touch the ingredient. Yet it does have some great benefits.[2,3] So what's the end-around?
ProtoTest: The Science Behind Natural DHEA Elevation
ProtoTest addresses these challenges through a fundamentally different approach. Rather than providing synthetic DHEA directly, ProtoTest delivers protodioscin, a steroidal saponin that serves as a natural precursor to DHEA production.
Understanding Protodioscin’s Mechanism
Protodioscin works by stimulating the body's endogenous DHEA production pathways.[4] This mechanism offers several advantages over direct DHEA supplementation:
- Natural Production Pathway: Instead of flooding the system with exogenous DHEA, protodioscin encourages the body to produce DHEA through its natural enzymatic processes. This approach tends to result in more physiologically appropriate hormone levels and better regulation.
- Regulatory/WADA Compliance: Protodioscin does not appear on any prohibited substances lists, including the 2025 WADA banned substances list. This makes ProtoTest suitable for military personnel, NSF-certified facilities, and competitive athletes subject to drug testing.
- Manufacturing Advantages: Unlike DHEA, protodioscin doesn't create the same contamination and processing challenges. This allows for cleaner manufacturing processes and more reliable formulations.
The Research Foundation
Human studies on protodioscin have demonstrated significant DHEA elevation. In one study involving 75 men, protodioscin treatment resulted in DHEA increases of 86% in non-diabetic participants and 55% in diabetic participants.[4]
Aura Scientific's ProtoTest is making waves in the hormone optimization space. With a Dioscorea Nipponica extract standardized for 50% protodioscin, it delivers the potent benefits that Tribulus was expected to provide years ago.
These results are significant because they demonstrate that protodioscin can achieve meaningful DHEA elevation through natural pathways. The study also noted improvements in sexual function, with 60% of participants experiencing increased frequency of successful sexual intercourse starting from day 10 of treatment.
Animal studies have been even more robust, showing that high-protodioscin extracts significantly increase testosterone, luteinizing hormone (LH), and dihydrotestosterone (DHT) levels while improving sexual behavior and sperm quality.[5]
In that study, protodioscin comes from none other than tribulus terrestris, the controversial libido-booster. However, due to inconsistency and poor standardization, that's not the best source for it.
Additional Benefits
Beyond hormone optimization, protodioscin has demonstrated significant benefits for male fertility parameters. In a study of 15 men with moderate idiopathic oligozoospermia, 60 days of protodioscin treatment led to remarkable improvements across multiple fertility markers. Sperm concentration increased to approximately 160% of baseline after treatment, continuing to rise to 200% of baseline 30 days after treatment concluded. The study also showed improvements in their motility and normal morphology percentages. Additionally, more than 80% of treated patients experienced restored and enhanced libido (and everything that comes with it) compared to before treatment, demonstrating protodioscin's comprehensive effects on male reproductive health.[6]
Why Dioscorea Nipponica Over Tribulus
ProtoTest is a significant innovation in protodioscin delivery thanks to its sourcing from Dioscorea nipponica root rather than the traditional Tribulus terrestris. This switch addresses longstanding issues with tribulus-based protodioscin extracts:

Standardization Challenges with Tribulus
Traditional tribulus extracts suffer from wildly variable protodioscin content. While many products are standardized to "saponins", this doesn't guarantee meaningful protodioscin levels since saponins encompass a broad class of compounds. Even extracts claiming high saponin content often contain minimal protodioscin - the actual bioactive compound responsible for hormonal effects.
Geographic origin, plant parts used, and extraction methods all dramatically affect protodioscin content in tribulus, making consistent results nearly impossible. This variability explains why tribulus research has been so inconsistent over the years.
Dioscorea Nipponica: A Superior Source of Protodioscin
Dioscorea nipponica offers several advantages as a protodioscin source:
- Consistent Extraction: The root material provides more reliable protodioscin yields, allowing for the 50% standardization that makes ProtoTest effective at lower doses.
- Research Support: Dioscorea nipponica has demonstrated benefits beyond hormone support, including anti-inflammatory effects and enhanced recovery from skeletal muscle atrophy.[7]
- Supply Chain Reliability: Unlike tribulus, which faces quality control challenges across different growing regions, Dioscorea nipponica provides a more stable supply of high-quality raw material.
Molecular Structure and Conversion Pathway
Protodioscin's effectiveness stems from its molecular structure, which contains the same steroid nucleus (cyclopentanoperhydrophenanthrene ring system) found in DHEA and testosterone. However, protodioscin includes complex sugar molecules (glycosides) that make it more water-soluble and affect its biological activity.
Protodioscin has the same steroid nucleus (cyclopentanoperhydrophenanthrene ring system) as DHEA and Testosterone, but with complex sugar molecules (glycosides) attached, which make it more water soluble. It gets converted to DHEA through enzymatic reactions, and DHEA gets converted into testosterone.
During metabolism, enzymatic processes remove these glycoside attachments, converting protodioscin through intermediary compounds into DHEA. This DHEA can then follow normal physiological pathways to produce testosterone and other androgens as needed by the body.
This natural conversion process offers better regulation than direct hormone supplementation, as the body can modulate production based on its current needs and existing hormone levels.
There's more research beyond that, which you can read about in our article titled "ProtoTest: Vitality Booster from Aura Scientific with 50% Protodioscin".
Enhanced Labs Case Study: Reformulation Success
Enhanced Labs Top T is raising the bar with ProtoTest and EndoFlo, two cutting-edge ingredients from Aura Scientific.
The practical benefits of switching from DHEA to ProtoTest are demonstrated in real-world reformulations. When formulating Top T, Enhanced Labs used ProtoTest dose to maintain efficacy while keeping manufacturing compliance.
This reformulation strategy accomplished several goals:
- Eliminated regulatory concerns for tested athletes
- Reduced manufacturing contamination risks
- Maintained the experiential benefits users expected
- Simplified the overall formulation by reducing total capsule count
The success of this approach validates ProtoTest's effectiveness as a direct DHEA replacement in hormone support formulations.
Synergistic Stacking: ProtoTest + EndoFlo
For maximum effectiveness, ProtoTest can be strategically combined with complementary ingredients that enhance its benefits. The recommended pairing is 200mg ProtoTest with 250mg EndoFlo, creating a dual-purpose formulation that addresses both hormone production and delivery.
EndoFlo: Enhancing Hormone Delivery
This blood flow-boosting ingredient, EndoFlo, consists of four key constituents: Mangifera indica (mango fruit extract), Kaempferia parviflora (black ginger), Ginkgo biloba, and Pinus massoniana (pine bark extract).
EndoFlo is Aura Scientific's proprietary four-ingredient blood flow complex containing Mangifera indica (mango fruit extract), Kaempferia parviflora (black ginger), Ginkgo biloba, and Pinus massoniana (pine bark extract). This combination creates powerful synergy with testosterone boosters like ProtoTest.
While ProtoTest works to optimize DHEA and downstream hormone production, EndoFlo ensures those hormones can effectively reach target tissues through enhanced circulation. The improved blood flow supports better nutrient delivery, waste removal during intense training, and the muscle "pump" effects that users seek from hormone optimization protocols.
Several EndoFlo constituents, including mango extract and black ginger, contain PDE5-inhibiting compounds that may provide additional benefits for male vitality beyond just muscle performance. This creates a comprehensive approach to hormone optimization that addresses both production and utilization.

Dosing and Implementation
ProtoTest's 50% protodioscin standardization allows for effective dosing at just 100-200mg per day, representing a significant improvement over traditional tribulus extracts that often require gram-level dosing for minimal effect.
The concentrated potency means that 100mg of ProtoTest delivers approximately the same protodioscin content as 7 grams of typical tribulus extract - which basically nobody uses (or should use)! This concentration advantage allows for convenient 1-2 capsule servings rather than the 6-7 capsule protocols common with DHEA-containing formulations.
The 'natural testosterone booster' category was long overdue for a shake-up, and the 50% protodioscin-powered ProtoTest is just the ingredient to do it.
For those stacking with EndoFlo, the recommended approach is:
- ProtoTest: 200mg daily
- EndoFlo: 250mg daily
This combination provides comprehensive hormone support while maintaining convenient dosing and excellent bioavailability.
