HorseBoost review: what the label and research show

HorseBoost is a strawberry gummy marketed for men's energy, stamina and vitality. Its label names nine active ingredients inside an 82 mg proprietary blend. We compared that panel with the sales page, the package prices and human studies.

What HorseBoost is

HorseBoost is a daily gummy sold through a SmartAdv tracking link that resolves to myhorseboost.com. Each bottle is said to contain 30 gummies. The page promotes men's energy, stamina, vitality and circulation. We found no published clinical trial of the finished formula.

The sales page describes six ingredients: muira puama, maca, catuaba, ashwagandha, L-arginine and tribulus. It also says the formula uses ideal dosages and links the ingredients to blood flow, testosterone and sexual vitality. Those claims need to be read alongside the actual label, which names three additional actives and withholds most individual quantities.

The label and formula

We read the seller's Supplement Facts artwork and describe it here because we found no written permission to host product images. The label states one gummy per serving and 30 servings per bottle. It lists an 82 mg proprietary blend of muira puama, maca, catuaba, green tea, caffeine, ashwagandha, L-arginine, tribulus terrestris and horny goat weed. Caffeine is shown as 5 mg in parentheses. The other eight amounts are not broken out.

The label also lists 10 calories, 3 grams of carbohydrate, 3 grams of added sugar and 4 mg of sodium per gummy. Its footnote says the blend is equivalent to approximately 567 mg of dry powders. That equivalence does not tell us the amount of any particular active ingredient, and it does not make the hidden amounts comparable with clinical doses.

What studies say about selected ingredients

The research below concerns single ingredients, not HorseBoost. Different extracts, doses and populations cannot be assumed to match this gummy. No trial tested the formula specifically in men over 50.

Maca: some small human studies, but no product dose to compare

In a randomized 12-week study, healthy men aged 21 to 56 took 1,500 mg or 3,000 mg of gelatinized maca daily, or placebo. Self-rated sexual desire differed from placebo beginning after eight weeks, while serum testosterone did not ^[1]. Another 12-week trial enrolled 50 men with mild sexual-function concerns and tested 2,400 mg of maca extract daily. Questionnaire improvement was greater than placebo, but modest ^[2]. Neither study shows whether HorseBoost's unknown amount is comparable.

Ashwagandha: a few trials used hundreds of milligrams

An 8-week randomized study assigned 100 healthy men aged 30 to 50 to 300 mg of ashwagandha root extract twice daily or placebo. The authors reported improvements in several sexual-function and semen measures ^[3]. In a crossover study of overweight men aged 40 to 70, a standardized extract was associated with higher testosterone and DHEA-S after eight weeks, but sexual well-being did not differ significantly between groups ^[4]. HorseBoost states neither its ashwagandha amount nor extract standardization.

Tribulus: positive individual trial, uncertain generalization

A 12-week placebo-controlled trial studied 180 men aged 18 to 65 using 1,500 mg daily of standardized Tribulus. Questionnaire scores improved versus placebo, with no group difference in adverse events ^[5]. A 2025 review found positive pooled sexual-function results across a small set of trials, but no significant overall testosterone difference; study methods and extracts varied ^[6]. HorseBoost gives no amount or standardization.

L-arginine: trial quantities are measured in grams

A review pooled ten randomized trials involving 540 men. Arginine amounts ranged from 1,500 to 5,000 mg daily, with a possible benefit on sexual-function measures in men with mild to moderate concerns ^[7]. A later trial tested 6 grams daily for three months in 98 men with blood-flow-related erectile difficulties ^[8]. HorseBoost does not disclose its arginine amount, so these results do not establish a product effect.

Muira puama, catuaba, green tea and horny goat weed

We did not locate a controlled human trial on male sexual-wellness outcomes that could verify the seller's mechanism statements for muira puama or catuaba. Green tea is not a featured ingredient on the sales page, and we found no relevant dose information for it on the label. Horny goat weed appears on the label but not in the six-item ingredient summary. We did not find a controlled human trial of this finished gummy, or evidence that the ingredient combination produces a specific outcome.

How HorseBoost compares with other vitality gummies

HorseFil is another men's vitality gummy. Its parallel review describes six named ingredients and no disclosed amounts. HorseBoost shows an 82 mg blend total and caffeine at 5 mg, but hides the other amounts and its sales summary omits three label actives. Neither lets readers compare the main ingredients with research doses.

Nitric Boost also leaves its active amounts undisclosed, including arginine. Alpha Drive has a larger total blend, hidden individual amounts and a sales-page to label mismatch. HorseBoost's listed price is higher per bottle than Alpha Drive's $29 to $49 range, though its 6-bottle pack is $49 each. These comparisons concern paperwork and price, not proof of effectiveness.

What the marketing says and what we could verify

The landing page calls the ingredients scientifically recognized and says the formula works through blood flow, testosterone and stress response. The references we checked support limited findings for some individual ingredients at specified doses. They do not establish that this combination raises testosterone, improves circulation or supports sexual wellness at the undisclosed quantities in one gummy. We could not trace the seller's phrase about ideal dosages to a formula trial or to a label that supplies those individual amounts.

We also noticed a mismatch in the ingredient presentation. The sales page names six actives, while the Supplement Facts image names nine, adding green tea extract, caffeine and horny goat weed. The label states caffeine at 5 mg, but it is not clear from the artwork whether that amount is counted inside the 82 mg blend total. A clear written explanation from the seller would resolve that point.

Price, packages and refund terms

Package prices shown through the SmartAdv listing and seller page are:

• 6 bottles: $49 per bottle, $294 total, free US shipping. At one gummy daily, this is a stated 180-day supply.
• 3 bottles: $69 per bottle, $207 total, free US shipping. This is a stated 90-day supply.
• 2 bottles: $79 per bottle, $158 total, plus shipping. The landing page does not show the shipping amount. This is a stated 60-day supply.

The seller states a 60-day satisfaction guarantee. Its FAQ also says customers should use the product for at least 30 days before requesting a refund. We did not find accessible seller terms that explain return shipping, product return requirements or how the window is counted, so check the checkout and keep the order details before purchase. Each bottle is said to contain 30 gummies; if a different serving direction is printed on the bottle you receive, follow that label and recalculate the supply.

Safety

Because the formula's individual amounts are hidden, the safety record of any single ingredient cannot establish the safety of this blend. The trials cited above involved specific extracts and doses. A 2022 meta-analysis of L-arginine trials found that supplementation lowered blood pressure on average, which is relevant if you use blood-pressure medication or have a condition where blood pressure changes matter ^[9]. Tell your doctor or pharmacist about the product before combining it with prescription medicines, particularly medicines that affect blood pressure or blood flow. The label includes caffeine, so account for caffeine from other sources too.

The seller's label advises people taking medication or managing a medical condition to consult a doctor before use. Results vary. Do not stop or change a prescribed treatment on your own. New or worsening changes in sexual wellness deserve medical evaluation, since they can have causes that supplements do not address.
