$48.99
Dark Labs | Creatine
$22.90

Creatine covers the high-output ATP side of performance while Devil Test covers the stress, hormonal, and vitality side. This is one of the cleanest pairings possible because there is essentially no functional overlap and both products benefit from daily consistency.

Take creatine daily anytime; use alongside Devil Test with a meal or post-workout

Whey Isolate or Whey Blend ProteinPROTEIN

A hormone-support product is only as useful as the training and nutrition around it. Pairing Devil Test with a high-quality protein ensures the recovery environment you are trying to support hormonally is matched with adequate amino acid intake for muscle repair and adaptation.

Use protein post-workout or anytime needed to hit daily protein targets

Vitamin D3 + K2VITAMIN MINERAL

Vitamin D status is closely tied to male health and hormone physiology, and boron is often discussed in the same broader support conversation. This is a smart stack for users building a more complete daily foundation rather than relying on one hormone product alone.

Take with a meal containing fat, ideally alongside or separate from Devil Test

Omega-3 Fish OilGENERAL WELLNESS

Fish oil supports systemic inflammation management, cardiovascular health, and recovery quality, complementing Devil Test’s stress and hormone-support focus. It is especially useful for users training hard while trying to keep long-term health markers in a good place.

Take daily with meals

Stim or Pump Pre-WorkoutPRE WORKOUT

Devil Test is not an acute training formula, so pairing it with a separate pre-workout makes sense. Because Devil Test is stimulant-free, it can stack cleanly with either a caffeine-based pre-workout for energy or a pump formula for blood flow and performance feel.

Take pre-workout 20-30 minutes before training; take Devil Test earlier in the day with food

Full Product Description Article

Dark Labs Devil Test is a fully disclosed hormone-support capsule formula built around three core goals: support a stronger androgen-friendly internal environment, improve resilience to stress that can drag performance and libido down, and enhance the uptake of key actives through dedicated absorption support. That matters, because this category is full of underdosed proprietary blends that lean on hype. Devil Test at least gives you the numbers.

The formula opens with Fadogia Agrestis Extract 10:1 at 600mg. This is one of the most talked-about ingredients in modern “test booster” formulas, but the evidence base is still limited and heavily driven by animal data rather than robust human trials. Mechanistically, it is positioned for testosterone support, but this is an ingredient where honesty matters: interest is high, human evidence is still thin, and the exact clinically validated human dose is not established. What you’re buying here is an aggressive inclusion, not a conclusively proven one.

KSM-66® Ashwagandha at 500mg is one of the formula’s strongest decisions. KSM-66® is a premium root-only extract with a strong research footprint for stress reduction, performance support, and male vitality outcomes. A 500mg dose sits in a practical, evidence-aligned range for helping lower stress burden and cortisol-related drag on recovery, mood, libido, and training consistency. This is one of the ingredients most users are likely to actually feel over 2-4 weeks through improved resilience, calmer baseline mood, and better readiness.

Epicatechin from Acacia catechu is listed at 300mg standardized to 40% catechins. That means you are not getting 300mg pure epicatechin; the standardization matters. Epicatechin is a flavanol associated with nitric oxide signaling, endothelial support, and exercise-recovery applications, with moderate evidence overall. It is an interesting inclusion in a testosterone formula because it broadens the product beyond hormones alone and may support performance feel, vascular function, and training quality.

Boron Citrate is listed at 200mg, but that is the compound weight, not elemental boron. Without the exact elemental yield disclosed, this is hard to benchmark precisely against the literature, which typically evaluates elemental boron in much smaller milligram amounts. That lack of elemental clarity is a real limitation. Boron is commonly used in hormone-support formulas for its relationship to free testosterone and vitamin D metabolism, but exact assessment here is incomplete.

DIM at 200mg is a meaningful inclusion for estrogen metabolism support. DIM, a compound derived from cruciferous vegetable chemistry, is used to shift estrogen metabolism toward more favorable pathways rather than “blocking estrogen” outright. In a men’s hormone formula, that creates a cleaner rationale when paired with androgen-support ingredients: support testosterone status while also supporting how estrogens are processed.

Tongkat Ali Extract 200:1 at 150mg is another high-interest inclusion. Tongkat is one of the better-known male vitality botanicals, commonly used for libido, stress resilience, and testosterone-support positioning. Because this is a concentrated 200:1 extract, the label suggests potency, but the lack of standardization details limits precise clinical comparison. Still, it fits the formula well alongside KSM-66® as a libido, drive, and stress-androgens bridge.

AstraGin® at 50mg and BioPerine® at 10mg strengthen the delivery side of the formula. AstraGin® has mechanistic and manufacturer-supported data for improving intestinal absorption of various compounds, while BioPerine® is the classic piperine absorption enhancer known for reducing rapid metabolism and improving uptake of certain actives. Their inclusion is especially logical in a capsule formula built on plant extracts.

As a system, Devil Test combines stress adaptation, androgen support, estrogen-metabolism support, and absorption support in one stack. It is fully transparent with no proprietary blend, which is a major win in this category. Day 1, you should not expect a stimulant-like “kick” because this is stim-free. In the first week, some users notice subtle changes in libido, training drive, or general well-being. Over 2-4 weeks, KSM-66®, Tongkat, and the overall hormone-support architecture are where the formula is designed to show its real value.

Science & Clinical References 11 citations
Ashwagandha and Stress-Mediated Performance0 studies

KSM-66® Ashwagandha is primarily relevant through hypothalamic-pituitary-adrenal axis modulation, helping reduce stress-related drag on recovery, libido, and training consistency. In practical terms, lowering chronic stress burden can indirectly support androgen status, sleep quality, and readiness to train. This makes adaptogen support especially valuable in lifters whose progress is limited more by allostatic load than by programming. Its effects are cumulative rather than acutely stimulatory.

DIM and Estrogen Metabolism Support0 studies

DIM is used for its influence on estrogen metabolism pathways rather than as a direct androgen booster. Mechanistically, it is discussed in relation to shifting metabolite balance and supporting a more favorable hormonal environment in some users. The practical appeal in male-support formulas is not immediate sensation, but internal environment management over time. Clinical interpretation depends heavily on form, bioavailability, and context.

Epicatechin and Muscle Signaling5 studies

Epicatechin is studied for effects on nitric oxide biology, antioxidant signaling, vascular function, and possible influence on myostatin-related pathways. In sports-nutrition positioning, it is often included to support training quality, muscle fullness, and performance-adjacent adaptations rather than direct acute stimulation. The 300mg dose sits at the upper end of common supplemental use. Human evidence is promising but still moderate overall.

Absorption Support with AstraGin® and BioPerine®6 studies

AstraGin® and BioPerine® are included to improve the practicality of a dense capsule formula by supporting nutrient uptake and intestinal transport processes. BioPerine® is most associated with enhancing bioavailability of co-administered compounds, while AstraGin® is marketed around transporter expression and absorption efficiency. In a multi-ingredient botanical stack, these components are less about headline effects and more about improving delivery. Their presence is a formulation-quality signal in disclosed products.

Quick Answers

What kind of product is Dark Labs Devil Test?

Devil Test is a stim-free hormone-support capsule formula built around Fadogia Agrestis 10:1, KSM-66® Ashwagandha, Tongkat Ali, DIM, boron, epicatechin, AstraGin®, and BioPerine®. It is designed for daily use to support male vitality, stress resilience, and a more androgen-friendly internal environment.

Does Devil Test contain caffeine or stimulants?

No. Despite a metadata inconsistency, the verified formula contains no caffeine or stimulant ingredients. This is a stim-free daily support product, which means it can be stacked with your normal pre-workout without overlapping stimulant load.

How long does Devil Test take to work?

This is not an instant-feel product like a pre-workout. Some users notice subtle changes in libido, mood, or daily drive within the first week, but the fairest evaluation window is 2-4 weeks of consistent daily use, especially because KSM-66® and broader hormone-support formulas perform best with consistency.

Why is KSM-66® important in this formula?

KSM-66® is one of the most established branded ashwagandha extracts in sports nutrition and wellness. At 500mg, it gives Devil Test a credible stress-management foundation, which matters because elevated stress can interfere with recovery, libido, and hormonal balance.

What does DIM do in a testosterone support formula?

DIM at 200mg is included to support estrogen metabolism rather than simply trying to “boost testosterone.” That makes the formula more balanced, because hormone optimization is not just about adding androgen-support ingredients—it is also about how your body processes related hormones.

Is the boron dose actually 200mg?

The label lists 200mg of boron citrate, which is the compound weight, not necessarily 200mg elemental boron. Because the elemental yield is not disclosed, it is difficult to compare precisely with studies that discuss elemental boron in much smaller amounts.

Can I stack Devil Test with creatine and pre-workout?

Yes. Devil Test fills a different role than creatine or a pre-workout. It pairs especially well with creatine monohydrate for strength and training output, and because Devil Test is stimulant-free, it can sit alongside your normal pre-training formula without caffeine overlap.

Should I take all 6 capsules at once?

Most users can take the full 6-capsule serving with a meal, but splitting it into 3 capsules twice per day is a smart option if you are sensitive to concentrated botanical formulas. The key is consistent daily intake, not a specific acute timing window.

Is Devil Test beginner-friendly?

It is better suited to intermediate users than complete beginners. Not because it is harsh, but because the formula is specialized and the benefits are more nuanced than a simple energy product or multivitamin.

Why include AstraGin® and BioPerine® together?

They support absorption through different but complementary mechanisms. In a capsule formula built around multiple extracts, improving uptake is a meaningful formulation advantage rather than a decorative add-on.
