Consider it. The better multi-herb vitality blend — a tonic stack, not a high-potency extract. A ~1000 mg epimedium base stacked with maca, saw palmetto and tongkat ali, in veggie capsules from a GMP-certified facility — the yohimbe-free of the two blends on our list.

Why It Scores 7.0 — And The Label Line Behind Each Number
Icariin standardisation
30% of scoreThe weakest axis by far: the listing discloses only about 10 mg of icariins from the ~1000 mg epimedium base — modest next to a standardised extract (Double Wood ~200 mg, Nootropics Depot ~100 mg). As a blend built on raw rather than highly-standardised herb, it simply doesn't deliver much active flavonoid, and that's the main reason it ranks below every single-herb extract.
Extract dose
25% of scoreA ~1000 mg horny goat weed base plus maca, saw palmetto and tongkat ali — a generous total herb load on raw weight. The score reflects that the raw epimedium amount is substantial, even though (per the icariin axis) little of it is standardised active flavonoid, and the co-herbs are in modest, typically non-clinical doses. Decent on bulk, light on standardised potency.
Purity & third-party testing
20% of scoreVegetarian capsules made in a GMP-certified USA facility from a recognisable brand — reasonable quality signals. But it's a multi-herb blend, which inherently dilutes epimedium-specific transparency: you can't see the icariin content clearly or verify each co-herb's dose, and there's no stated independent potency/heavy-metal panel like Double Wood's. Acceptable for a blend, below the single-herb leaders.
Value per day
15% of scoreAbout $0.55 per two-capsule serving on an estimated $14-19 for 60 caps (30 servings) — a one-month supply at the highest per-serving cost among the value-oriented picks. You're paying for multiple herbs rather than concentrated epimedium, so on a cost-per-active-flavonoid basis it's poor value; on a cost-per-tonic-stack basis it's reasonable. Mid-pack at best.

Real-world response
10% of scoreScored measured and non-medical. A popular, well-reviewed multi-herb tonic stack is a legitimate thing to want, and recognisable-brand familiarity counts. But none of the herbs has robust human evidence for libido or erectile function, and the modest ~10 mg icariins limits the epimedium contribution, so we reward the transparent (for a blend) formulation rather than promising an outcome.

Marketing Claims Vs. Reality
A complete 'sexual energy' complex with horny goat weed, maca, saw palmetto and tongkat ali.
The four herbs are genuinely present and disclosed — a real multi-herb blend around a ~1000 mg epimedium base. The 'complex' description is accurate; what's modest is the standardised active content of each component, not the presence of the herbs.
1000 mg of horny goat weed per serving.
The ~1000 mg epimedium base is real, but it's the raw herb amount, not a standardised one — the listing discloses only ~10 mg of icariins from it. So the '1000 mg' is accurate on weight but misleading if read as high potency: a standardised 1000 mg at 20% would deliver ~200 mg icariins, twenty times more. Accurate number, low active content.
Vegetarian capsules made in a GMP-certified facility.
The product uses vegetarian capsules and states GMP-certified USA manufacturing, which we credit as stated. Genuine quality signals and a real plus for vegetarians, even if the blend format limits epimedium-specific transparency.
Boosts sexual energy, drive, and performance for men and women.
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 at ~10 mg icariins — improves libido, drive, or performance. Fair as traditional vitality-tonic framing; overstated if read as a proven benefit.
Suitable for men and women.
Accurate — the herbs are traditional tonics used across both sexes, and the marketing positions it for men and women. The usual exclusions apply (pregnancy/breastfeeding; hormone-sensitive conditions warrant medical advice). Saw palmetto is more typically a men's-health herb but isn't a contraindication for women in a blend like this.
What Our Test Actually Found
The ~10 mg icariins is the number that defines this product
Everything about Zhou follows from one disclosure: roughly 10 mg of icariins. That's modest — a standardised extract delivers ten to twenty times more active flavonoid per serving. The reason is that this is a blend built on a raw 1000 mg of epimedium rather than a concentrated, standardised extract, so most of that gram is herb material rather than icariin. If you came to horny goat weed for the icariin, this product gives you very little of it, and that single fact is why it ranks below every single-herb extract on the list.
It's a tonic stack — judge it as a combination, not as epimedium
The right way to evaluate Zhou is as a traditional multi-herb 'sexual energy' tonic, not as a horny goat weed product. Around the epimedium it stacks maca (energy/libido), saw palmetto (prostate/DHT-associated), and tongkat ali (the most substantiated of the three for testosterone, via SHBG displacement). For a buyer who likes the idea of several traditional vitality herbs in one capsule, that's the appeal. Just understand the co-herbs are in modest, typically non-clinical amounts — this is a tonic blend, not four separately-effective actives at full dose.
The better-made of the two blends — but still a blend
Among the two multi-herb complexes on our list, Zhou's real advantage is that it is yohimbe-free: vegetarian capsules, a GMP-certified facility, a recognisable well-reviewed brand, and no stimulant. On disclosure the picture flipped after our 27 Aug 2026 label re-read: Horbäach's panel quantifies a 500 mg epimedium component at 10% icariins (~50 mg/serving) — about five times Zhou's ~10 mg — which is why Horbäach now ranks a spot above Zhou despite the yohimbe caution. If you want the stack concept without a stimulant, Zhou remains the choice; if you want the most icariin in a blend and can clear the yohimbe with a clinician, Horbäach delivers more.
Pricier per day and a shorter supply
At roughly $0.55 per two-capsule serving and a 60-cap bottle giving 30 servings, Zhou is the most expensive per day among the value-oriented picks and offers only a one-month supply. You're paying for multiple herbs rather than concentrated epimedium, so on cost-per-active-flavonoid it's poor value. If days-per-dollar or icariin-per-dollar matters, the single-herb value tubs (Nutricost, Swanson) are far more economical; Zhou's cost only makes sense if the multi-herb stack itself is what you want.
Calibrate the expectation — and consider a standalone if one herb is the goal
Zhou is a legitimate, well-made traditional tonic stack, but it can't change the evidence: none of its herbs has robust human-trial data for libido or erectile function, and its epimedium contributes only ~10 mg of icariins. So buy it for the combination concept with a measured expectation — not as a proven performance product or an ED treatment. And if it turns out one specific herb is really what you're after (a well-dosed tongkat ali, say), a focused standalone product will serve you better than a modest amount of it inside a blend.

A ~1000 mg epimedium base stacked with maca, saw palmetto and tongkat ali, in veggie capsules from a GMP-certified facility — the yohimbe-free of the two blends on our list. But it discloses only ~10 mg of icariins (modest), the co-herbs are in non-clinical amounts, and a 60-cap bottle is a 30-day supply at a higher per-day cost. Consider it only if you specifically want the multi-herb concept, with a measured expectation. Not an ED treatment.
Zhou is the pick if — and only if — you specifically want a multi-herb 'sexual energy' stack rather than a pure horny goat weed extract. Around a roughly 1000 mg epimedium base it layers maca, saw palmetto and tongkat ali, in vegetarian capsules from a GMP-certified USA facility, from a well-reviewed and recognisable Amazon brand for this category. As blends go, it's the yohimbe-free one of the two on our list. But the honest trade-off is right there in the spec: it discloses only about 10 mg of icariins, a modest amount of the active flavonoid next to a standardised extract delivering ten to twenty times that. A blend inherently tells you less about how much epimedium you're really getting, and the co-herbs are present in modest, typically non-clinical amounts. So this scores as a 'consider', not a default buy — right for the stack concept, wrong if you want epimedium potency. And the standing caveat applies: none of these herbs has robust human evidence for treating ED. Buy Zhou for the tonic stack with clear eyes, not as a high-potency horny goat weed. Here's the full breakdown.
The better vitality blend — consider it only if you specifically want the multi-herb stack.
Zhou is the right pick for one specific buyer: the person who wants a traditional multi-herb 'sexual energy' tonic in a single capsule, not a pure horny goat weed extract. Around its ~1000 mg epimedium base it stacks maca, saw palmetto and tongkat ali, in vegetarian capsules from a GMP-certified facility, and as blends go it's the yohimbe-free one of the two on our list. If the combination concept is genuinely what you're after, it's the reasonable choice. But it scores as a 'consider' rather than a default buy for honest reasons. It discloses only about 10 mg of icariins — ten to twenty times less active flavonoid than a standardised single-herb extract — its co-herbs are in modest, typically non-clinical amounts, and a 60-cap bottle is a 30-day supply at the highest per-day cost among the value picks. So if the active flavonoid is your priority, Toniiq (#1), Double Wood (#2) or Nootropics Depot (#3) deliver far more; if you want a well-dosed version of one of the co-herbs (tongkat ali in particular), a standalone product beats a small amount in a blend. And the standing caveat holds — none of these herbs has robust human evidence for treating ED, so hold a measured expectation. Buy Zhou for the stack concept with clear eyes, or buy a single-herb extract for potency.

07NOW Horny Goat Weed + Maca
NOW Foods is the recognisable-name option for buyers who like the idea of a little maca alongside their horny goat weed.
Quick Answers
Why is the icariin so low — only ~10 mg?
Because this is a multi-herb blend built around a raw 1000 mg of horny goat weed rather than a standardised extract. The listing discloses roughly 10 mg of icariins from that epimedium — a modest amount next to a standardised single-herb extract, where Double Wood delivers ~200 mg (20% of 1000 mg) and Nootropics Depot ~100 mg (50% of 200 mg). The difference is standardisation: a 1000 mg of raw or lightly-standardised herb contains far less icariin than 1000 mg standardised to 20%. So if the active flavonoid is your priority, this isn't the pick — its value is the multi-herb stack, not epimedium potency.
What do the extra herbs — maca, saw palmetto, tongkat ali — add?
They make it a vitality stack rather than a pure epimedium extract. Maca is a traditional energy/libido root; saw palmetto is more associated with prostate and DHT-related uses; and tongkat ali (Eurycoma longifolia) is the one with the most substantiated testosterone-related evidence of the three, working by displacing testosterone from SHBG. The honest caveat is that in a blend like this, the individual doses of each co-herb are typically modest and often not individually clinically-dosed, so think of them as a traditional tonic combination rather than four separately-effective actives. If you specifically want a well-dosed tongkat ali, our Tongkat Ali hub covers standalone options.
Will it treat erectile dysfunction or boost libido?
No — keep expectations grounded. None of the herbs here 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 this product discloses only ~10 mg of it, and a multi-herb blend doesn't change the underlying lack of human efficacy data. It's a traditional 'sexual energy' tonic stack, not a medication. Use it with a measured expectation; if erectile dysfunction is your actual concern, see a clinician for proven treatments and because ED can be an early sign of cardiovascular issues.
Should I buy a blend like this or a pure single-herb extract?
For transparency and potency, a single-herb extract wins; for the convenience of a tonic stack in one capsule, a blend like Zhou is the trade. A pure epimedium extract (Toniiq, Double Wood) tells you the icariin percentage and lets you compare potency; Zhou discloses only ~10 mg icariins and modest co-herb amounts, so you give up that clarity. Zhou is the yohimbe-free blend of the two on our list — vegetarian capsules, GMP-certified facility, recognisable brand — so if you've decided you want the multi-herb concept without a stimulant, it's the gentler choice. Just buy it knowing it's a stack, not a high-icariin horny goat weed.
How long does a bottle last and how is it dosed?
The serving is two capsules, so the 60-capsule bottle is 30 servings — about a one-month supply, the shortest run among the value-oriented picks. At an estimated ~$0.55 per serving it's also pricier per day than the single-herb value tubs, which reflects the multiple herbs in the formula. As with any traditional tonic, take it consistently over weeks to judge how it suits you rather than expecting an acute effect, and hold the expectation measured given the modest disclosed icariin.

In vitro, icariin inhibited cGMP-specific PDE5 with an IC50 of 0.432 µmol/L — the mechanistic basis for the herb's reputation, but a bench/enzyme finding, not proof of a human benefit. Especially relevant here, since this blend discloses only ~10 mg of icariins.

Note this blend's ~10 mg icariins is far below that 60 mg trial dose. Cited to keep expectations calibrated.
