How Does Horse Force Work? 3 Ingredient Groups, Explained
Horse Force works by combining 8 ingredients from three groups into one 1,200 mg blend: men's roots led by tongkat ali, prostate herbs like saw palmetto, and a mineral and a glandular. Tongkat ali has the best human evidence for raising testosterone in men with low levels. Because the label does not publish any single amount, nobody outside the maker can confirm how much of that mechanism actually reaches you.
How does Horse Force work, in one picture?
Horse Force is built around one idea: put several traditional men's ingredients into a single capsule and let them work together. The label calls this the "Test Boost Proprietary Blend," 1,200 mg spread across 8 ingredients in a 2-capsule serving.
None of the eight ingredients is a stimulant. None acts in minutes. The mechanisms below are slow ones: hormone signaling, blood flow and, for two of the eight, glandular and mineral support that some research links to testosterone. Understanding the mechanism does not tell you the dose, because the label keeps that number hidden inside the 1,200 mg total.
We split the eight into three groups by what they are meant to do: men's roots, prostate herbs, and minerals and glandulars. Each group below links to the actual research, not marketing copy, so you can see the proposed mechanism next to the evidence for it, ingredient by ingredient.
The 3 mechanism groups at a glance
| Group | Ingredients | Proposed mechanism | Human evidence |
|---|---|---|---|
| Men's roots | Horny goat weed, tongkat ali, wild yam, sarsaparilla | Hormone signaling and blood-vessel relaxation, mostly through testosterone or nerve pathways | Mixed: moderate for tongkat ali, weak for the other three |
| Prostate herbs | Saw palmetto, nettle root | Blocking a testosterone-to-DHT enzyme and reducing prostate-tissue inflammation | Weak to moderate; aimed at urinary symptoms, not stamina |
| Minerals and glandulars | Boron, orchic substance | Freeing up bound testosterone (boron) and supplying glandular material (orchic substance) | Limited for boron; weak, with no human trials, for orchic substance |
This table groups mechanisms, not doses. For the milligram picture, see Horse Force ingredients or the label itself on Horse Force Supplement Facts.
Group 1: the men's roots
Group 1: horny goat weed, tongkat ali, wild yam and sarsaparilla. These are the roots most associated with men's formulas, and they work through different, mostly hormonal, pathways.
Tongkat ali is the strongest link in the chain. A systematic review and meta-analysis of pooled clinical trials found it raises serum testosterone, especially in men with low baseline levels, across doses of roughly 100 to 600 mg a day (Leisegang et al., 2022). A 6-month trial combining 200 mg a day with exercise training improved erectile function and testosterone in about half the men studied (Leitão et al., 2021). The proposed mechanism is a rise in luteinizing hormone that signals the testes to make more testosterone. Horse Force lists tongkat ali as a plain powder, not the standardized root extract most trials used, which changes how reliably that mechanism fires.
The main compound in horny goat weed, icariin, is proposed to relax blood vessels the way PDE5-inhibiting drugs do, based on rat studies of nerve-injured animals (Shindel et al., 2010). No controlled human trial has tested this mechanism for sexual function or performance, and a human safety trial found high icariin doses absorb poorly and can upset the stomach (Brown et al., 2019).
Wild yam contains diosgenin, a plant steroid some sellers claim the body converts into DHEA or progesterone. The one controlled human trial tested this mechanism directly, as a topical cream, and found no change in hormone levels versus placebo (Komesaroff et al., 2001). Sarsaparilla has a proposed anti-inflammatory mechanism from lab and animal data only; no human trial has tested it (Memorial et al., 2024).
Group 2: the prostate herbs
Group 2: saw palmetto and nettle root. Both work on the prostate and urinary tract, not on testosterone or stamina, and neither is a testosterone mechanism at all.
The proposed mechanism for saw palmetto is blocking an enzyme (5-alpha-reductase) that turns testosterone into DHT, the hormone linked to prostate enlargement. A 2023 Cochrane review of 27 trials in 4,656 men found that, in practice, saw palmetto taken alone produces little to no difference in urinary symptoms versus placebo, at standard or triple dose (Franco et al., 2023). NCCIH reports the same finding and adds that saw palmetto does not change PSA readings (National Center for Complementary and Integrative Health (NCCIH), 2024).
Nettle root's proposed mechanism includes reducing prostate-tissue inflammation and binding proteins that free up testosterone. A 12-week randomized trial at 450 mg a day improved symptom scores and oxidative-stress markers in men with an enlarged prostate (Karami et al., 2020), though it is more often studied combined with saw palmetto than alone. Neither herb's mechanism supports a stamina or performance claim, and neither treats a diagnosed prostate condition.
Group 3: minerals and glandulars
Group 3: boron and orchic substance. One is a trace mineral with a specific, if small, human trial. The other is animal tissue with almost no human data at all.
Boron's proposed mechanism is reducing sex-hormone-binding globulin, the protein that binds testosterone and keeps it inactive; less binding leaves more free testosterone available. A small trial in 8 healthy men found 10 mg a day raised free testosterone and lowered estradiol within one week (Naghii et al., 2011). It is the one ingredient here with a fairly specific dose tied to a real, if tiny, mechanism study. NIH sets an adult upper limit of 20 mg of boron a day from all sources (National Institutes of Health, 2024); Horse Force does not say how much boron is inside its blend.
Orchic substance is dried bovine testicular tissue. Its proposed mechanism is glandular support, supplying raw material the body is assumed to use to make its own hormones, though this idea has little modern research behind it. A supplement reference rates the evidence for any use, including raising testosterone, as insufficient (RxList et al., 2024). Being bovine glandular material, it also falls under the FDA's import caution on high-risk bovine tissue from BSE-affected countries (U.S. et al., 2024).
Do the three groups work together?
Putting three mechanism groups in one capsule does not prove they work together. Horse Force is sold as a single formula, but each ingredient's research was done on its own, usually testing one mechanism at a time.
- What we know: each ingredient has at least one proposed mechanism, and several have small human trials behind that mechanism
- What we do not know: whether combining all eight changes, boosts or cancels out any single mechanism
- What the label claims: only energy, stamina and performance support, which stays narrower than the individual mechanisms above
A combination formula can still be reasonable to try; it just is not the same as proof the combination works. See the honest read on what are the benefits of Horse Force?
What Horse Force's mechanism does not tell us
The mechanisms above come from the individual ingredients' own research, tested one at a time, usually alone and often at a higher dose than 1,200 mg could hold for all eight combined. Nobody has published a trial of the Horse Force formula itself. So we do not know: how much of any ingredient is actually inside, whether the ingredients interact with each other inside the body, whether the blend works as a whole the way each ingredient works alone, or how long it takes to feel any change. The label's own claims stay narrow — supports energy, stamina and performance — and make no testosterone or medical claim, which matches how thin the whole-product evidence is.

How It Works: common questions
How does Horse Force work?
It combines 8 ingredients in three groups: men's roots led by tongkat ali, prostate herbs, and a mineral plus a glandular. Each has its own proposed mechanism; none has been tested as the finished blend.
Does Horse Force raise testosterone?
The label makes no testosterone claim. Tongkat ali and boron each have small human studies linking them to higher testosterone, but the finished blend has not been tested, and amounts are not published.
What is the strongest mechanism in Horse Force?
Tongkat ali's link to testosterone, from a meta-analysis of pooled trials at roughly 100-600 mg a day. Horse Force lists it as a powder, not the extract those trials used.
Do saw palmetto and nettle root work through the same mechanism as tongkat ali?
No. They work on prostate and urinary-tract pathways (blocking an enzyme, reducing inflammation), not on raising testosterone or stamina.
Is there research on the Horse Force formula itself?
No published trial tests the finished 8-ingredient blend. All research cited here tested individual ingredients alone, so combining them is untested.
Which group does the label's stamina claim rely on most?
The men's roots group, mainly tongkat ali. The prostate herbs and the minerals/glandulars group have weaker or no direct link to stamina in the research.
How fast should Horse Force's mechanism work?
The label gives no timeline. Most tongkat ali trials ran 2 weeks to 6 months, so any effect would likely build gradually, not immediately.
Which two ingredients have the weakest known mechanism?
Sarsaparilla and orchic substance. Neither has a controlled human trial testing its proposed mechanism.
