Horse Peak names its ingredients rather than hiding them in a proprietary blend, which makes it possible to actually assess. Below is each one described honestly — established nutritional roles and traditional use — plus, flagged clearly, which ones interact with common medications. That second part matters more than any benefit description.
The Horse Peak formula
🩸 L-Arginine Blood pressure
An amino acid the body uses to make nitric oxide, which is involved in the normal relaxation of blood vessels and healthy circulation. May affect blood pressure — this is the ingredient behind the nitrate warning below, and the reason anyone on blood-pressure medication should check first.
🌿 Epimedium (Horny Goat Weed) Interacts widely
A herb with centuries of traditional use in Chinese herbal practice, associated with vitality and stamina. May affect blood pressure and interact with blood thinners, and is known to interact with a number of prescription medicines. Worth naming honestly: despite how it's often marketed, it is not a treatment for erectile difficulties.
🌱 Panax Ginseng Interacts widely
Korean ginseng, a classic adaptogen traditionally used to support physical stamina, alertness and the body's response to stress. Can interact with several medicines — including blood thinners, diabetes medication and antidepressants — and may affect blood sugar.
⚙️ Zinc Essential mineral
An essential mineral that contributes to the maintenance of normal testosterone levels in the blood, normal fertility and normal immune function. Note the wording carefully: maintenance of normal levels — this supports what's already in a healthy range rather than raising it beyond it. High intakes over a long period can interfere with copper absorption, so check what else you're taking.
🏔️ Maca Root Traditional adaptogen
A Peruvian root traditionally used to support energy and stamina, containing vitamins, minerals and plant antioxidants. Generally well tolerated; some people find it mildly stimulating, so earlier in the day suits most.
🌾 Tribulus Terrestris Hormone-sensitive conditions
A plant long used in traditional medicine and popular in men's formulas for general vitality support. Not suitable for hormone-sensitive conditions without medical advice. Worth being honest here too: despite its reputation, human research has generally not supported the testosterone claims often made for it.
⚠️ Important safety information — please read
Read this before combining with any medication. If you take nitrates (for chest pain or heart conditions) or prescription medication for erectile difficulties, do not start this or any circulation-supporting supplement without your doctor's approval — together they can cause a serious drop in blood pressure.
Speak to your doctor first if you take blood-pressure medication, blood thinners, diabetes medication or antidepressants, or if you have a heart, liver, kidney, thyroid or hormone-sensitive condition, or are due to have surgery. Panax Ginseng and Epimedium in particular interact with a number of prescription medicines.
Adult men only. Not for anyone under 18, and not intended for women, especially during pregnancy or nursing. Stop use and seek medical advice if you notice dizziness, palpitations, chest discomfort, headache or any other unusual symptom.
Persistent difficulty is a medical matter, not a supplement one. Ongoing erectile problems can be an early sign of cardiovascular disease, diabetes, low testosterone, a medication side effect, or stress and depression. Please get it checked properly rather than self-treating — it is genuinely worth doing.

See Current PricingIs it natural and safe?
The formula is marketed as natural, non-GMO and stimulant-free, made in an FDA-registered, GMP-certified facility. Two precise points worth making: FDA registration is not FDA approval — the FDA does not approve dietary supplements — and "natural" is not the same as risk-free. Several of these botanicals are active enough to interact with prescription medication; that's precisely why anyone taking anything regularly should have the conversation first. For healthy adult men not on medication, this is a familiar and generally well-tolerated list.
