Safety
Is Horse Force Safe? Side Effects and Interactions
Quick answer
No safety study has tested the finished Horse Force formula. Its 1,200 mg blend targets hormones through tongkat ali and orchic (animal gland) substance. See a doctor first if you take medicine or have a heart, blood-pressure, prostate or hormone-sensitive condition. Take no more than 2 capsules a day, and stop if you react badly.
What do we know, and not know, about Horse Force safety?
We know what is in the capsule. We do not know how much of each part it holds, and no one has tested the finished blend in people.
The label lists one Test Boost Proprietary Blend of 1,200 mg per 2-capsule serving. Two of its eight parts, tongkat ali and orchic substance, are chosen for their link to male hormones.
- 0published safety studies on this formula
- 8ingredients in one blend
- 2capsules a day, the label maximum
That leaves safety to the label's cautions, what is known about single ingredients, and your doctor's view of your health.
Who should talk to a doctor before taking Horse Force?
Some men should not start without a doctor's okay. The label itself says to consult a physician if you have a known medical condition.
| If you have or take | Why a doctor check comes first |
|---|---|
| A hormone-sensitive condition | Tongkat ali and orchic substance are included for their link to male hormones. Raising hormones may be unwise with some conditions. |
| A prostate condition | The blend has saw palmetto, nettle root and hormone-active parts. Your doctor should know before any prostate test. |
| Heart disease | Men's performance products are sometimes used alongside heart drugs, and some fakes hide drugs that clash with them. |
| High or low blood pressure | Blood-pressure changes can be serious. Blend amounts are not published, so your doctor cannot size the risk. |
| Any daily prescription | Eight herbs and a gland extract in unknown amounts are hard to check for interactions. |
| Diabetes, liver or kidney disease | These change how the body handles herbs and minerals. |
| Age under 18 | The label says children under 18 should consult a physician. The product is made for adult men. |
What are the possible side effects of the Horse Force ingredients?
Reports on single ingredients give some clues. They do not tell you how this mix will act, because doses and products differ.
| Ingredient | What is known | Main open question |
|---|---|---|
| Tongkat ali root | A 2022 review of trials found it may raise total testosterone in men (Leisegang et al., 2022). | Its share of the blend is not published. |
| Saw palmetto fruit | Generally well tolerated; mild stomach upset and headache are reported (NCCIH, 2025). | Little or no benefit found for prostate symptoms. |
| Horny goat weed leaf | Studied mostly in the lab, with little human data. | Human safety at any dose is poorly known. |
| Nettle root | Used traditionally for urinary symptoms. | Amount unknown. |
| Wild yam root | The body does not turn it into testosterone. | Why it is in a "Test Boost" blend. |
| Sarsaparilla root | An old tonic herb, once used in root beer. | Little modern safety data. |
| Orchic substance | Dried animal testicular tissue. | Source animal and processing not published. |
| Boron chelate | Upper limit 20 mg a day for adults (NIH ODS). | Amount per serving not published. |
If you notice stomach upset, headache, trouble sleeping, a racing heart or skin changes after starting, note the day and the dose. The ingredients guide explains each part in more depth.
How much boron is too much?
The adult upper limit for boron is 20 mg a day from all sources (NIH ODS). Typical daily intake from food and drink is about 1 to 1.5 mg.
The NIH fact sheet notes no clinically relevant drug interactions with boron. The risk here is stacking, not the capsule alone.
When boron could add up
- You also take a multivitamin with boron
- You take a separate bone or joint formula with boron
- You take a second men's product at the same time
Read every label and add up the boron you can see. The 1,200 mg blend shares its weight across eight parts, so boron from this capsule alone is unlikely to be large.
What is unknown about the orchic substance?
Orchic substance is dried animal testicular tissue. The label does not say which animal it comes from or how it was processed.
That leaves questions a careful buyer should know about before starting.
- Which animal species it comes from
- Where the animals were raised and how they were checked
- How the tissue was dried, cleaned and tested
- Whether any hormone content remains after processing
It also means the product is not vegetarian, and the gelatin capsule adds a second animal source. More detail is in our article on what orchic substance is.
When should you stop taking Horse Force?
Stop at once and get help if you have a serious reaction. For milder problems, stop and call your doctor.
Call 911 or go to the ER for
- Chest pain, pressure or a racing, uneven heartbeat
- Fainting or severe dizziness
- Swelling of the face, lips or throat, or trouble breathing
- An erection that lasts more than four hours
Stop and call your doctor for
- Stomach upset, headache or poor sleep that does not ease
- Rash, itching or hives
- Changes in urination
- Mood changes, such as irritability or low mood
- Yellow skin or eyes, or dark urine
You can report a reaction to the FDA through MedWatch. It helps track problems with supplements.
How can you take Horse Force more safely if your doctor agrees?
If your doctor says it is fine, a few habits lower the risk.
Start with one capsule
The label allows one or two a day. One lets you see how you react.
Stay at or under two
Never take more than two capsules a day, as the label says.
Take it with water
The label says to take it with an 8 oz glass of water.
Do not stack products
Avoid a second men's formula or extra boron at the same time.
Keep a short log
Write down the dose and how you feel each day for the first weeks.

Horse Force safety: common questions
Does Horse Force have side effects?
No side-effect data exists for the finished formula. Single ingredients have their own reports, such as mild stomach upset with saw palmetto. Your own response may differ.
Can I take Horse Force with blood pressure medicine?
Ask your doctor first. The label says anyone with a known medical condition should consult a physician, and the blend amounts are not published for your doctor to review.
Is Horse Force safe for men over 60?
Age alone is not the issue. Older men are more likely to have heart, blood-pressure or prostate conditions and to take daily medicines, which is why a doctor check comes first.
Can Horse Force affect a PSA test?
Saw palmetto has been studied for prostate symptoms, and several parts of the blend act on hormones. Tell your doctor you take it before any prostate test.
How much boron is in Horse Force?
The label does not say. Boron is one of eight parts in a 1,200 mg blend. The adult upper limit is 20 mg a day.
Is Horse Force safe for women?
The listing presents it as a formula made for men. The label says pregnant or nursing women should consult a physician, and the hormone-active parts make it a poor fit.
Does Horse Force contain Viagra or similar drugs?
None is listed on the label. The FDA has found hidden drugs in many men's products sold online, which is why buying through the authorized route matters.
What should I do if I took more than 2 capsules?
Do not take more that day. If you feel unwell, call your doctor or Poison Control at 1-800-222-1222.
