Two Horse Boost ingredients have genuine human trials behind them, three have mechanism or mixed results, and two rest on tradition alone. Every trial dose is larger than what an 82 mg blend can carry, and that gap is the most important fact on this page.
How this grading works
Every ingredient below is graded on the human evidence that exists for the ingredient itself, then checked against what an 82 mg blend can plausibly deliver. Those are two different questions and conflating them is how supplement pages mislead people honestly.
No study has been run on Horse Boost as a finished product. That is normal for this category and worth stating anyway, because a claim about an ingredient is not a claim about a gummy that contains a fraction of that ingredient.
Moderate human evidence: Maca and Ashwagandha
Maca is the strongest entry in Horse Boost. Multiple small randomised trials in men report improved self rated sexual desire after eight to twelve weeks of daily use, and consistently find no change in testosterone, luteinizing hormone or oestradiol. Trial doses typically run 1.5 g to 3 g of dried root per day.
Ashwagandha has repeated placebo controlled trials on perceived stress and cortisol, with some work on sleep quality and on sperm parameters in subfertile men. Doses run 250 mg to 600 mg of standardised root extract daily. Both ingredients therefore have real science behind them at doses far above anything an 82 mg blend can hold.
- Maca: moderate evidence for desire, none for hormones, weeks not days
- Ashwagandha: moderate evidence for stress, dose in the hundreds of milligrams
- Blend total available: 82 mg across nine entries
Mixed or mechanistic: Arginine, Tribulus, Horny Goat Weed
L-Arginine has a well described mechanism and mixed clinical results. Oral arginine raises nitric oxide availability, but the studies showing vascular effects use 3 g to 6 g a day, and absorption is poor enough that some researchers prefer citrulline instead.
Tribulus mostly fails to raise testosterone in controlled work, with a few trials reporting better desire scores anyway. Horny Goat Weed rests almost entirely on laboratory work with icariin on nitric oxide signalling, with little human confirmation. Mechanism is a reason to include an ingredient. It is not the same as proof.
The only fair test of a formula this size is running it properly inside the 60 day Horse Boost guarantee.
Get Horse BoostTraditional only: Muira Puama and Catuaba
Both Brazilian barks belong in the honest column. Muira Puama has a small number of open label observations and centuries of Amazonian use. Catuaba has preclinical work and South American herbal tradition. Neither has a controlled human trial that would satisfy a sceptical reader.
That is not the same as saying they do nothing. It is saying that nobody has established what they do, at what dose, in whom. A page that dresses tradition up as clinical support is lying to you, whatever else it says. The full list is in the ingredient breakdown.
What the evidence cannot tell you
The honest summary: Horse Boost contains two ingredients with genuine human data, three with mechanism or mixed data, two with tradition alone, plus green tea, 5 mg of caffeine and a sugar base. The doses in trials are consistently larger than what an 82 mg blend can carry.
So the evidence cannot tell you that this gummy will work, and it cannot tell you that it will not. It can tell you the direction is plausible, the dose is modest, and the sensible test is the seller's own 60 day guarantee run properly.

Nothing here is medical advice, and no supplement treats a medical condition. If arousal or energy changed suddenly, that is a conversation for a doctor, not for a gummy.
