Consider it. The biggest blend — long, cheap, broad and fully quantified on the panel, but it contains yohimbe. A 180-capsule value tub bundling a 500 mg epimedium extract (10% icariins, ~50 mg/serving) with 150 mg maca, 100 mg tribulus, 40 mg yohimbe and 40 mg L-arginine — every component quantified on the panel.

Why It Scores 7.4 — And The Label Line Behind Each Number
Icariin standardisation
30% of scoreThe panel states a 500 mg epimedium extract standardised to 10% icariins — about 50 mg per two-capsule serving, the same 10% tier as Nature's Way and Swanson. (Corrected 27 Aug 2026: we originally scored this axis 4.6 as 'undisclosed'; the bottle discloses it plainly.) It sits a notch below the pure single-herb 10% picks because the standardised epimedium is one component of a five-part blend built on ratio-extract equivalence marketing.
Extract dose
25% of score500 mg of 15:1 epimedium extract per two-capsule serving — at the low end of the list's raw doses (Double Wood 1000 mg, NOW 750 mg; equal to Nature's Way and Swanson's 500 mg), topped up with small co-herb doses (150 mg maca, 100 mg tribulus, 40 mg each of yohimbe and L-arginine). The '7,500 mg equivalent' framing is ratio-extract marketing; the real number is the 500 mg standardised extract.
Purity & third-party testing
20% of scoreThe label states vegetarian, non-GMO, gluten-free, and the panel quantifies every component — better transparency than we originally credited. What still pulls this axis down: it contains yohimbe, an ingredient with genuine cardiovascular cautions that not every buyer should take, and only brand-own seals ('Packaged & Lab Tested in the USA', GMP) — no independent third-party certifier (NSF, USP) is stated. Below the single-herb leaders on safety profile and stated testing.
Value per day
15% of scoreAbout $0.17 per two-capsule serving on an estimated $13-18 for 180 caps (90 servings) — a long, cheap supply, the most servings among the blends. Strong on raw price. The caveat is that you're buying a fully quantified but yohimbe-containing complex, so the low cost-per-serving only translates to value if this specific broad stack is genuinely what you want.

Real-world response
10% of scoreScored measured and non-medical. A broad 'everything' stack appeals to some buyers, and the quantified panel means you at least know what you're taking. What limits the score is the yohimbe: it makes the response less predictable and adds a stimulant risk not everyone should take. None of the ingredients has robust human evidence for libido or erectile function, so we reward neither potency nor outcome here.

Marketing Claims Vs. Reality
A complete complex with horny goat weed, tribulus, maca, yohimbe and L-arginine.
The five ingredients are genuinely present and — a correction from our earlier reporting — the Supplement Facts panel quantifies each of them individually: 500 mg epimedium extract (10% icariins), 150 mg maca 4:1, 100 mg tribulus 20:1 (45% saponins), 40 mg yohimbe (2% alkaloids), 40 mg L-arginine per two-capsule serving.
High-potency horny goat weed formula.
The panel does state a 500 mg epimedium extract standardised to 10% icariins (~50 mg/serving), so the potency is disclosed and real — but 'high-potency' oversells it: 10% on 500 mg is the same mid-tier as Nature's Way and Swanson, well below Double Wood's 20% at 1000 mg or Toniiq's 40%. The '15:1, equivalent to 7,500 mg' framing is ratio marketing, not extra icariin.
Vegetarian, non-GMO, gluten-free.
Per the label, the product is vegetarian, non-GMO and gluten-free — genuine formulation attributes we credit as stated. These are real positives, though they speak to the capsule and sourcing rather than to the potency of the active herbs, which the panel does disclose separately (10% icariins, 45% saponins, 2% yohimbine alkaloids).
Supports male enhancement, drive, and performance.
The honest caveat. Icariin is a real in-vitro PDE5 inhibitor (Xin 2003, PMID 12646997) and Epimedium has human bone-density RCT data (Zhang 2007, PMID 17419678), but NO robust human trial shows standalone horny goat weed — or this multi-herb blend — improves drive or performance, and the yohimbe adds risk rather than proven benefit. Fair as traditional tonic framing; overstated as a proven benefit.
Suitable for daily use.
True for many healthy adults, but qualified by the yohimbe: a yohimbe-containing stimulant blend is not appropriate for daily use by people with high blood pressure, heart conditions, anxiety, or on interacting medications, who should consult a clinician first. 'Suitable for daily use' is fair only with that caveat clearly attached.
What Our Test Actually Found
Correction: the label says 100 mg of tribulus, not 40 mg
An earlier version of this review said the tribulus extract in this blend was 40 mg. The Supplement Facts panel reads: Tribulus Terrestris Extract (a 20:1 extract, equivalent to 2,000 mg of Tribulus Fruit) (Standardized to contain 45% Saponins) 100 mg. We re-read the label on Sep 3, 2026 and revised the tribulus figure everywhere it appeared in this review, along with two leftover sentences that still called the blend 'undisclosed' or the yohimbe 'unstandardised' from an earlier correction pass — the panel has always individually quantified and standardised every ingredient, tribulus included. Text only: the true 100 mg is still a minor co-herb dose next to the 500 mg epimedium extract, so the Extract dose axis stays 7.4 and overallScore stays 7.4.
The yohimbe is the headline — and a genuine caution
Unlike every other pick on our list, Horbäach contains yohimbe, and that fundamentally changes its risk profile. Yohimbe (and yohimbine) is a stimulant that can raise heart rate and blood pressure and trigger anxiety, jitteriness or palpitations in sensitive people. Anyone with hypertension, a heart condition, an anxiety disorder, or on interacting medications (including some antidepressants and stimulants) should consult a clinician before taking it — and many would be better off avoiding it. This isn't a benign herb-only formula, and the yohimbe is the single most important thing to understand before buying.
Correction: the panel quantifies everything — we originally said it didn't
In our original review we called this an undisclosed proprietary complex and ranked it last for opacity. That was wrong, and we've corrected it (27 Aug 2026): the Supplement Facts panel individually quantifies every component — a 500 mg epimedium 15:1 extract standardised to 10% icariins (~50 mg icariins per two-capsule serving), 150 mg maca 4:1, 100 mg tribulus 20:1 (45% saponins), 40 mg yohimbe extract at 2% yohimbine alkaloids, and 40 mg L-arginine. On disclosure it now scores in the same 10% tier as Nature's Way and Swanson, and its overall score rose from 6.6 to 7.4, lifting it above Zhou. The ratio-equivalence marketing ('equivalent to 7,500 mg') still deserves a discount, and the yohimbe caution above still defines the product.
Breadth is the pitch — but the co-herb doses are small
Horbäach's pitch is the widest possible stack: five ingredients in one capsule. For a buyer who likes the everything-at-once idea, that breadth is the appeal. But read the quantities: beyond the 500 mg epimedium extract, you get 150 mg of maca, 100 mg of tribulus and just 40 mg each of yohimbe and L-arginine — modest doses dressed up by ratio-equivalence claims ('100 mg of a 20:1 extract, equivalent to 2,000 mg'). Tribulus is weakly evidenced at any dose, and the most consequential ingredient (yohimbe) is the one that adds risk rather than proven benefit. The blend is honest on paper, light in substance.
Cheap and long-supply, but compare it to a clean alternative
The 180-capsule tub at ~$0.17 a serving is genuinely cheap and long-lasting — the most servings of any blend here. But weigh that against the yohimbe. If a long, cheap supply is what you're after, Nutricost (#5) also gives you 180 caps, but as clean single-herb epimedium with no stimulant. So the 'value' of Horbäach's big tub only holds if this specific broad, yohimbe-containing stack is precisely what you want — otherwise a cleaner option offers similar economy without the trade-off.
Calibrate the expectation — and weigh the risk
Horbäach is a broad traditional 'everything' stack, but it can't change the evidence: none of its ingredients has robust human-trial data for libido or erectile function, ~50 mg of icariins is no proven human dose, and the yohimbe adds cardiovascular risk rather than proven benefit. So this is a quantified tonic blend with a stimulant caveat, not a proven performance product or an ED treatment. Consider it only with a measured expectation, a clear understanding of the yohimbe risk, and ideally a clinician's sign-off — and for most buyers, a clean single-herb extract is the better decision.
Full analysis: all pros & cons (6), buy if / skip if

A 180-capsule value tub bundling a 500 mg epimedium extract (10% icariins, ~50 mg/serving) with 150 mg maca, 100 mg tribulus, 40 mg yohimbe and 40 mg L-arginine — every component quantified on the panel. One caveat defines it: it contains yohimbe, a stimulant that can raise heart rate and blood pressure. Long, cheap supply, but not for everyone. Consider it only if you specifically want this broad a stack and are comfortable with the yohimbe. Not an ED treatment.
Horbäach is the everything-in-one-capsule big tub: 180 capsules bundling epimedium with tribulus, maca, yohimbe and L-arginine, at a low price. For a shopper who wants the broadest possible vitality stack and the longest cheap supply, it has real appeal — and a correction is due here. Label truth (corrected 27 Aug 2026): we originally described this as an undisclosed proprietary complex. The Supplement Facts panel in fact quantifies every component — a 500 mg epimedium extract standardised to 10% icariins (~50 mg per two-cap serving), 150 mg maca 4:1, 100 mg tribulus 20:1 (45% saponins), 40 mg yohimbe (2% alkaloids) and 40 mg L-arginine — and its score and rank rose accordingly. What keeps it below every single-herb pick is the yohimbe: a stimulant that can raise heart rate and blood pressure and isn't for everyone, so you should check with a clinician before taking it, especially with cardiovascular concerns or other medications. And the standing caveat applies — none of these ingredients has robust human evidence for treating ED. Consider Horbäach only if you specifically want this broad a stack and are comfortable with the yohimbe. Here's the full breakdown.
The biggest blend — consider it only with clear eyes about the yohimbe.
Horbäach is the broadest, cheapest, longest-supply option on our list — a 180-capsule tub bundling epimedium with tribulus, maca, yohimbe and L-arginine. For a buyer who specifically wants the widest possible vitality stack in one capsule and the lowest cost per serving, that breadth and price have appeal. A correction first (27 Aug 2026): we originally called this an undisclosed proprietary complex — in fact the Supplement Facts panel quantifies every component, including a 500 mg epimedium extract at 10% icariins (~50 mg per serving), and its score rose from 6.6 to 7.4 and its rank from #9 to #8 accordingly. What still keeps it below every single-herb pick is the yohimbe — a stimulant that can raise heart rate and blood pressure and genuinely isn't for everyone, so check with a clinician before taking it, especially with any cardiovascular concern, anxiety, or other medications. And the standing caveat applies: none of these ingredients has robust human evidence for treating ED. Consider Horbäach only if you specifically want this broad a stack and are comfortable with the yohimbe — for most buyers, a clean single-herb extract (Toniiq #1, Double Wood #2, or Nutricost #5 for a long cheap supply without yohimbe) is the better, safer decision.
If This Doesn’t Fit — Try These
04Nature's Way Horny Goat Weed
Nature's Way is the dependable mainstream answer: a real, consistently standardised 10%-icariin extract from a brand that has been on pharmacy shelves for decades, in non-GMO vegan capsules at a friendly price.
09Zhou Horny Goat Weed Complex
Zhou is the yohimbe-free of the two multi-herb blends, and the right pick if you want a vitality stack without a stimulant: around its 1000 mg epimedium base it layers maca, saw palmetto and tongkat ali, in vegetarian capsules from a GMP-certified facility.
01Toniiq Horny Goat Weed
Toniiq wins by doing the one thing that matters most in this category transparently: it tells you the icariin content (40%), keeps the formula to a single concentrated herb, and states third-party testing.
Quick Answers
Should I be concerned about the yohimbe in this product?
It's worth taking seriously. Yohimbe (and its alkaloid yohimbine) is a stimulant that can raise heart rate and blood pressure, and cause anxiety, jitteriness, or palpitations in sensitive people — it's the single biggest reason this product needs a caution. If you have high blood pressure, any heart condition, an anxiety disorder, or take medications (including antidepressants or stimulants), you should talk to a clinician before taking a yohimbe-containing supplement, and many people are better off avoiding it entirely. Unlike the other picks on our list, this isn't a benign herb-only formula — the yohimbe genuinely changes the risk profile.
How much icariin or epimedium am I getting?
About 50 mg of icariins per two-capsule serving. The Supplement Facts panel states a 500 mg horny goat weed extract (a 15:1 concentrate) standardised to contain 10% icariins — so, unlike we originally reported (we called this an undisclosed proprietary complex; corrected 27 Aug 2026 after reading the panel), both the epimedium dose and the standardisation are printed on the bottle. That puts its icariin content in the same tier as Nature's Way and Swanson (both 10% on 500 mg), though still well below Toniiq's 40% or Double Wood's 20% at 1000 mg. The real differentiator versus the single-herb picks isn't opacity — it's the yohimbe.
What's in the blend besides horny goat weed?
Tribulus terrestris, maca, yohimbe and L-arginine. Tribulus is a popular but poorly-evidenced 'testosterone' herb; maca is a traditional energy/libido root; yohimbe is the stimulant discussed above; and L-arginine is an amino acid precursor to nitric oxide, sometimes included for blood-flow reasons. Each is individually quantified on the panel: 150 mg maca 4:1 extract, 100 mg tribulus 20:1 extract (standardised to 45% saponins), 40 mg yohimbe extract (standardised to 2% yohimbine alkaloids, ~0.8 mg yohimbine), and 40 mg L-arginine per two-capsule serving. The co-herb doses are modest — the ratio-extract equivalence claims ('equivalent to 2,000 mg tribulus') do a lot of marketing work — so treat them as a light traditional garnish around the epimedium, and note that the most consequential ingredient from a safety standpoint is the yohimbe.
Will it treat erectile dysfunction or boost libido?
No — be clear-eyed. None of these ingredients has robust human-trial evidence for treating erectile dysfunction. Horny goat weed's icariin inhibits PDE5 in the test tube (Xin 2003, PMID 12646997), but ~50 mg of icariins is no proven human dose for sexual outcomes; tribulus and maca have modest, mixed evidence; and while yohimbine has been studied for ED, the 40 mg of yohimbe extract standardised to 2% yohimbine alkaloids (~0.8 mg yohimbine) in this blend is not the same as a controlled clinical dose and carries real cardiovascular cautions. This is a traditional 'everything' tonic stack, not a medication. If erectile dysfunction is your concern, see a clinician — both for proven treatments and because ED can be an early cardiovascular sign.
Is the big 180-capsule tub good value?
On pure price, yes — 180 capsules / 90 servings at roughly $0.17 a serving is a long, cheap supply, the longest among the blends. But value has to be weighed against the defining caveat: the formula contains yohimbe, so it's cheap per serving but not for everyone. If you want a genuinely long, cheap supply of clean single-herb epimedium instead, Nutricost (#5, 180 caps) gives you that without the yohimbe. The big tub is only a bargain if this specific broad stack is what you actually want.

This product's ~50 mg icariins per serving is in that study's range on paper, but for a bone outcome, not a sexual one. Cited to keep expectations calibrated.
