HorseFil review: six ingredients, no disclosed amounts

HorseFil is a gummy marketed for men's energy, circulation and sexual wellness. We checked what the seller lists against published human research. Several ingredients have been studied, but the page leaves out the information needed to judge the formula itself.

What HorseFil is

HorseFil is sold as a daily gummy. Its FAQ says to take one gummy with water and says a bottle contains 30 gummies. The sales page and FAQ name six ingredients: tongkat ali, maca root, ashwagandha, horny goat weed, L-arginine HCl and grape seed. The page does not show individual milligram amounts or a readable Supplement Facts panel.

There is a small inconsistency in the seller's material. The main product page names six ingredients, while the FAQ describes the formula as having seven active ingredients and then names only some of them. We cannot identify a seventh ingredient from the page we reviewed. The bottle label should be checked against the product description before taking it.

The marketing connects its ingredients with testosterone, libido, circulation and male performance. Those are claims about the advertised formula. The human studies we found investigated individual ingredients, often as standardized extracts at stated doses. They did not test HorseFil as sold, and the missing amounts prevent a meaningful comparison.

The formula next to the research

Here is what can and cannot be established from the listing. Study findings below describe those study products and participants, not a result we can attribute to HorseFil.

Tongkat ali: a signal in specific extracts

A randomized trial enrolled 105 men aged 50 to 70 and compared standardized Physta root extract at 100 mg or 200 mg daily with placebo for 12 weeks. Total testosterone increased relative to placebo in the 200 mg group at weeks four, eight and twelve, while free testosterone did not differ significantly between groups. The paper disclosed industry funding and author employment related to the extract supplier, which matters when weighing a single trial ^[1].

A separate trial examined 200 mg daily of a freeze dried water extract in men over five weeks and reported changes in quality of life and sexual well-being measures ^[2]. A later review pooled nine clinical studies, five in a meta-analysis, and reported a rise in total testosterone, while noting that further work was needed ^[3]. None of this establishes what HorseFil contains or whether its extract is comparable.

Maca: modest research, no dose to compare

In a double blind randomized trial, healthy adult men received 1,500 mg or 3,000 mg of maca daily for 12 weeks. The researchers reported a difference in self rated sexual desire beginning at week eight, without a corresponding change in testosterone. The sample and follow up were limited, and the result applies to the tested maca preparation and amount ^[4]. HorseFil lists maca but does not publish an amount or extract details.

Ashwagandha and ginseng: details matter

A small eight week randomized study assigned 50 adult men with lower sexual desire to 300 mg of root extract twice daily or placebo. The authors reported improved questionnaire scores in the extract group. That is a preliminary finding from a particular extract and serving, not evidence that an undisclosed quantity in a multi ingredient gummy has the same effect ^[6].

The main product page does not list ginseng. The FAQ's count of seven ingredients makes it unclear whether it is included. A Cochrane review of nine ginseng trials found low certainty evidence and described the average change on one sexual function measure as small. The trial preparations also varied ^[5]. We would want the full panel to resolve whether ginseng is present.

L-arginine and grape seed

A meta-analysis included ten randomized trials with 540 participants and studied L-arginine amounts between 1,500 and 5,000 mg daily. Another randomized trial used 6 g daily for three months in men with circulation related sexual function concerns ^{[7] [8]}. These are gram level amounts. Because HorseFil does not state how much L-arginine HCl it contains, the comparison stops there.

In a crossover study with 28 evaluable healthy volunteers, grape seed extract at 100 mg three times a day did not significantly change the metabolism of dextromethorphan. That one finding cannot rule out interactions with other medicines or different grape seed products ^[10]. We found no usable human trial of horny goat weed for the marketing purpose described.

What the sales claims can support

The page presents a broad mechanism: ingredients are said to affect testosterone, libido, circulation and performance. PubMed includes studies of tongkat ali, maca, ashwagandha and L-arginine, but each tested a named preparation and a known amount. The seller does not provide enough formula detail to trace a study to the HorseFil gummy. We also found no published clinical trial of the finished product.

HorseBoost is the closest comparison because it is also promoted through SmartAdv and sold as a one gummy daily men's vitality formula. Both sellers show the same package prices: $158 plus $9.99 shipping for two bottles, $207 for three, and $294 for six. The HorseBoost package page and label artwork show an 82 mg proprietary blend, with caffeine disclosed separately at 5 mg and eight other ingredients inside the blend. HorseFil names six ingredients on its sales page but does not disclose any amount. Both products leave important dose questions unanswered, though HorseBoost at least states the total blend and caffeine amount. The ErecPrime review, by contrast, lists individual amounts, which allows a dose by dose comparison even when the evidence remains uncertain. Our Boostaro review also explains how undisclosed doses limit a buyer's ability to assess a vitality formula.

Price, packages and refund terms

The seller shows three packages. One bottle is described as 30 gummies with one gummy daily, or about 30 days. Prices below are the per bottle figures on the listing; the two bottle offer also adds shipping.

• 6 bottles: $49 each, $294 total, free US shipping, about 180 days.
• 3 bottles: $69 each, $207 total, free US shipping, about 90 days.
• 2 bottles: $79 each, $158 total, plus $9.99 US shipping, about 60 days.

The seller advertises a 60 day satisfaction guarantee. Its FAQ refund rules add conditions: the minimum trial period is 30 days, only sealed bottles qualify for return, shipping and customs are excluded, the buyer pays return shipping, and a 20 percent restocking fee is deducted. Contact support for return authorization. Those conditions narrow the practical value of the guarantee, especially if several bottles have been opened.

Safety

The undisclosed amounts and unclear seventh ingredient make individualized safety review harder. L-arginine has been studied for blood pressure: a meta-analysis of 22 randomized trials found average reductions in systolic and diastolic readings, though results varied by dose and study group ^[9]. Men using blood pressure medicines or other prescriptions should show the complete bottle label to a doctor or pharmacist before trying the product. The grape seed interaction study found no meaningful change for one tested medicine, but that does not settle interactions across medications ^[10].

Ask your doctor before taking a supplement if you use prescription medication, have a health condition, or are unsure about an ingredient. Follow the label on the bottle you receive, since the online page leaves out amounts and has an ingredient count mismatch. Results vary, and new or worsening symptoms deserve medical care.

What we liked and what gave us pause

Frequently asked questions

How many gummies are in a serving?

The seller FAQ says one gummy daily with water and 30 gummies per bottle. Check the printed product label when it arrives.

Does the seller publish the amount of each ingredient?

We did not find a readable Supplement Facts panel or individual amounts on the sales page. Without those figures, a dose comparison with research is not possible.

Is HorseFil a recurring order?

The seller FAQ says the order is one time with no automatic renewal. Review the checkout summary before paying.

Can I return opened bottles?

The FAQ refund rules state that only sealed bottles qualify. They also list a 20 percent restocking fee, return shipping paid by the customer, and a 30 day minimum trial within the 60 day request window.

Does the research show that HorseFil works?

No study of the finished HorseFil formula was found. Studies of individual ingredients cannot establish the effects of this product, especially when its ingredient amounts are not published.

How we reviewed HorseFil

We fetched the SmartAdv tracking link through a US side reader, reviewed the HorseFil product page and FAQ, and checked the seller terms linked from its site. We searched PubMed for human research on the listed ingredients and verified every PMID using PubMed eutils esummary. We compared study amounts and extracts with the seller's disclosure. We did not test the product on people, and nobody at Stark Verve is a medical professional. Read our editorial policy to learn how we choose and update reviews.
