Straight-up hormone support with KSM-66®, Tongkat, DIM, and Fadogia—all doses shown
Dark Labs Devil Test is a straight-up hormone-support capsule with full doses listed, focusing on three big things: building a better setup for androgens, boosting your ability to handle stress that kills performance and libido, and ramping up how well your body absorbs the key stuff. That's huge in a world of skimpy hidden blends full of hype. At least here, you see the real numbers.
It kicks off with 600mg of Fadogia Agrestis Extract 10:1. This one's buzzing in test booster circles, but honestly, the proof is mostly from animal studies, not a ton of solid human trials yet. It's meant for testosterone support, but let's keep it real: hype is high, human data is light, and there's no locked-in perfect dose for people. You're getting a bold amount here, not something proven beyond doubt.
Then there's 500mg KSM-66® Ashwagandha, one of the smartest picks in the mix. This is a top-shelf root extract with solid research for cutting stress, boosting performance, and supporting guy stuff like vitality. 500mg is a good, research-backed dose that can help dial down stress and cortisol, making recovery, mood, libido, and training steadier. This is the one a lot of guys actually notice in 2-4 weeks—more chill, better bounce-back, and feeling ready to go.
Epicatechin from Acacia catechu comes in at 300mg, standardized to 40% catechins. So, it's not pure 300mg epicatechin; that standardization counts. Epicatechin is a flavanol linked to nitric oxide boosts, better blood flow, and recovery from workouts, with okay evidence behind it. It's a cool add in a test formula because it goes beyond just hormones and might make training feel smoother while the other stuff builds up.

Key Highlights
- 600mg Fadogia Agrestis 10:1 extract hits hard as the lead ingredient in test boosters. Human proof is still spotty, but this ain't a weak throw-in—it's meant to drive the test-support vibe for real.
- 500mg KSM-66® Ashwagandha is a standout here. It's a high-end root extract great for stress and performance, and cutting stress is a smart way to keep recovery, drive, and guy vitality on point.
- 150mg Tongkat Ali 200:1 extract brings a focused boost for guys' performance. It's popular for libido, motivation, and test support, pairing great with KSM-66® in this setup.
- 200mg DIM helps with estrogen processing, not just pumping up testosterone. That's key because a good hormone stack should handle both sides—boosting androgens and managing estrogens right.
- 300mg epicatechin extract makes this more than a basic test booster. It's tied to nitric oxide, blood flow, and workout benefits, so training might feel better as the hormone side kicks in over time.
- 50mg AstraGin® is in here to help soak up nutrients better. The makers' data shows it boosts how well stuff gets absorbed, which is perfect for a capsule full of botanicals.
- 10mg BioPerine® adds another absorption boost by helping uptake and slowing down quick breakdown of compounds. In a mix like this, that's a clever move, not just filler.
- No hidden blends—every ingredient and dose is right on the label. In a category loaded with shady 'male matrix' hides, this transparency is a big win.

Who Is This For?
- Seasoned guy lifters in a stressful work stretch who crush it one week and flop the next. 500mg KSM-66® fits perfect since stress control quickly boosts steady drive, recovery, and libido when training's intense.
- Bodybuilders leaning out or recomping who want hormone backup without stims. Tongkat Ali, DIM, boron, and Fadogia combo helps keep an androgen-friendly vibe when calories, sleep, or recovery are tight.
- Guys over 30 feeling like recovery, motivation, and libido aren't as easy as back in the day. This works because it steps up from basic zinc-magnesium with real doses of KSM-66®, Tongkat Ali, and DIM.
- Lifters who hate hidden blends and want to know what's going in. Devil Test shows everything, a big plus in test support where tons hide behind weak blends and tiny doses.
- Athletes on creatine, protein, and pre-workout looking for stim-free daily base. This covers hormone setup, stress toughness, and week-long consistency, not quick energy.
- Folks who like adaptogens and herbs wanting something bolder than plain ashwagandha. Fadogia, Tongkat, and KSM-66® build a wider guy-performance boost than single-ingredient stuff.
How to Use
Down 6 capsules daily with 8-12 ounces of water, best with a meal. Food helps because these strong herbs and BioPerine® can be rough empty-stomach for some. If you're new to heavy herb mixes, try 3 caps for 3-4 days to check tolerance, then go full. It's stim-free hormone support, so no need for workout timing—daily consistency beats perfect slots. Lots of folks do breakfast or lunch, or split doses to ease the gut. Stacks well with creatine, whey, fish oil, vitamin D, magnesium, and pre-workout. Don't mix with other test boosters unless you're stacking smart and know the overlaps. Keep it cool and dry, and run it steady for 2-4 weeks before deciding.
What to Expect
Day 1's usually low-key: no stim kick, no big start, no fake energy since it's caffeine-free. In the first few days, some guys pick up on small shifts in well-being, libido, or stress, mostly from KSM-66® and the guy-support mix. By week 1, if you vibe with adaptogens and Tongkat, you might feel readier day-to-day and a steadier gym mindset. Weeks 2-4 are when it shines—KSM-66® steady use, DIM's hormone help, and the full stack's buildup really hit. Epicatechin adds to better workout feel over time via blood flow and recovery. Judge this over weeks, not minutes.

Frequently Asked Questions
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.
