What are the nine names on the VigorHorse ingredients list?

Start with the list itself, because it is short. The panel prints nine names under one blend line of 82 mg, in this order: muira puama extract, maca extract, catuaba extract, green tea extract, caffeine, ashwagandha, L-arginine, tribulus terrestris and horny goat weed extract. The sections below check each name against what has been published. No study listed here tested VigorHorse itself.

Evidence tiers follow how the urology guide and the 2020 aphrodisiac review sort this category. Doses are as the abstracts state them.

Which names have human trials behind them?

Maca extract

A Peruvian root grown above 4,000 metres. It is the name with the cleanest record for desire. In the 2002 trial, healthy men took either 1,500 mg or 3,000 mg daily for twelve weeks. Their self-rated desire rose from about week eight, while testosterone stayed put. A later study set 3.0 g against 1.5 g a day, and only the higher arm worked.

L-arginine

An amino acid the body turns into nitric oxide. The mechanism is textbook, and the question is always the amount. The trial that worked ran six weeks at 5,000 mg a day. A crossover at 1,500 mg a day did no better than placebo. Blood pressure only shifted from about 4,000 mg a day upward.

Ashwagandha

An Ayurvedic root with the biggest trial file on the label. The vitality trial used an extract giving 21 mg a day of withanolide glycosides. A fertility pilot gave 675 mg of root extract daily across 90 days. In the 2026 hormone meta-analysis, TSH and T3 were unchanged. Two liver-injury case series involved stand-alone extracts at hundreds of milligrams a day.

Tribulus terrestris

A loud reputation and a thin record. Two trials, one at 800 mg a day for 30 days and one at 450 mg a day for five weeks, both came back negative on their main outcomes. Young men given 10 to 20 mg per kilogram of body weight each day showed no androgen change. The 2026 meta-analysis calls the combined picture weak.

Caffeine

Printed as 5 mg. That is about a twentieth of a small coffee, and one eightieth of the 400 mg a day that two safety reviews call an unremarkable adult intake. Only caffeine gets a figure of its own, so nobody has to guess it.

Which names have only lab or animal work?

Horny goat weed extract

The seller's written pack says Horny Goat Weed (Icariin). The printed panel says Horny Goat Weed Extract and prints no standard figure. We follow the jar, so we do not claim any icariin content. The chemistry is real but early: icariin blocks the PDE5 enzyme in a test tube at 5.9 micromolar, and the animal work gave rats 10 mg per kilogram. Neither is a human result, and neither makes this gummy work like a prescription tablet.

Green tea extract

This is the concentrated leaf extract, not the brewed drink. Its catechins have been studied at hundreds of milligrams a day, and the US Pharmacopeia reviews put their liver-safety concern in that same range. A fraction of an 82 mg blend sits below both ranges.

Which names have no controlled human trial at any dose?

Two of the nine. Muira puama is an Amazonian bark whose chemistry has been mapped. Searches turn up plant chemistry and rodent work, with no controlled human trial for sexual function. Catuaba is a Brazilian bark sold under a name that two unrelated plant families answer to, and the jar prints no species. The study people cite tested Catuama, a four-herb mix, on rabbit tissue at 1-10 mg. The tissue was in a lab bath and the preparation held four herbs, so it tells us little about catuaba in a gummy.

Neither name should be called research-backed. Being honest about that does not make them harmful. It only means the evidence is missing.

How much of each name is inside one gummy?

Nobody outside the maker can say. The panel gives a single total, 82 mg, covering all nine. Split it evenly and each name gets about 9 mg. Take the label's own footnote instead, which calls the blend equivalent to approximately 567 mg of dry powders, and the even split is about 63 mg a name. The real split is surely uneven.

There is one clue that costs nothing. Blends list their members from the heaviest to the lightest. Caffeine is printed fifth and carries 5 mg. The four names printed after it, ashwagandha, L-arginine, tribulus and horny goat weed, therefore weigh 5 mg or less each. Set that beside 5,000 mg of arginine and 675 mg of ashwagandha in the studies, and the gap is plain.

What else is inside a VigorHorse gummy?

Eight other ingredients: corn syrup, cane sugar, water, apple pectin, sorbitol liquid, natural flavors, citric acid and sodium citrate dihydrate. The first two are sugars, which is why each gummy has 3 g of added sugar and 10 calories. Apple pectin sets the gummy, so the base is not gelatin. The jar carries no vegetarian or vegan mark, which is a separate claim. The label also says Produced in a GMP Facility and Made in the USA with globally sourced ingredients.

What should you check on your own jar?

1. Count the names under the blend line. There should be nine, ending with horny goat weed extract.
2. Read the blend total and the footnote: 82 mg, equivalent to approximately 567mg of dry powders.
3. Find the 5 mg inside the caffeine entry.
4. Read the added sugar row: 3 g, 6% Daily Value.
5. Look for artwork revision REV 05/26 in the corner, and compare the lot on the base with VIG-26/MY-7014.

Which sources back these facts?

Each study named above, listed in one place. These sources describe the ingredients in their own research, not the finished gummy.

Frequently asked questions

Our view

A list is only the start. What we find most useful here is the gap between the list and the studies. Five of the nine names have human trials, but those trials used grams of maca and arginine, hundreds of milligrams of ashwagandha and tribulus, and far more caffeine than one gummy holds. Two names have no controlled human trial at all.

That does not make the gummy a trick. It makes it a sampler: small shares of well-known names, in a chewable you can keep taking. If you want one ingredient at a tested dose, buy that ingredient on its own. If you want a simple daily habit and can live with one shared number, this is a fair way to try it. Ask your doctor first if you take medicine or have a health condition.
