Male Enhancement Supplements and Nitrates: The Danger
Nitrates for chest pain must not be combined with sildenafil or tadalafil, because blood pressure can fall to dangerous levels. FDA has found those drugs, unlisted, in products sold for sexual enhancement. If you take nitrates, talk to a doctor or pharmacist before using any enhancement supplement. We found no source saying Stallion Power contains hidden drugs.

Why nitrates and enhancement drugs clash
Nitrates and the drugs in some enhancement products both lower blood pressure. Together they can lower it too far.
MedlinePlus says not to take sildenafil with nitrates for chest pain, such as nitroglycerin, isosorbide dinitrate or isosorbide mononitrate. The same warning covers "poppers" (amyl, butyl nitrate or nitrite) (MedlinePlus, Sildenafil). The AHA adds that ED medicines should not be used with nitrate therapy for chest pain from coronary artery disease (AHA, Sexual activity and heart disease).
That is a drug rule. It matters for supplements because some products sold for sexual enhancement have contained drugs that are not on the label.
What FDA found in two named products
FDA laboratory analysis found sildenafil and tadalafil, not listed on the label, in a product sold for sexual enhancement. The notice is dated May 29, 2026. FDA advises people not to buy or use it (FDA, X10 hidden-drug notice). An older notice, dated 2015, describes the same two drugs in another product found through international mail shipments (FDA, Wild Sexx hidden-drug notice).
Both notices warn that the hidden drugs may interact with nitrates and drop blood pressure to dangerous levels. They also note that people with diabetes, high blood pressure, high cholesterol or heart disease often take nitrates (FDA, X10 hidden-drug notice) (FDA, Wild Sexx hidden-drug notice). Those two notices are about named products. They say nothing about Stallion Power, and no source we read says it contains hidden drugs.
| Group | Why it matters | Source |
|---|---|---|
| People who take nitroglycerin or similar medicine | Must not combine with sildenafil-type drugs | (MedlinePlus, Sildenafil) |
| People with heart disease, high blood pressure or high cholesterol | Often prescribed nitrates | (FDA, X10 hidden-drug notice) |
| People with diabetes | Often prescribed nitrates | (FDA, X10 hidden-drug notice) |
| Users of "poppers" | Same warning as nitrate medicine | (MedlinePlus, Sildenafil) |
ED pills and supplements interaction: where the gap is
The ED pills and supplements interaction problem has two parts. The first is a known drug that is hidden in a bottle. The second is a herb that may act on blood pressure by itself. NCCIH warns that products marketed for sexual enhancement may contain prescription drugs that are not allowed in supplements, or ingredients missing from the label (NCCIH, Using Dietary Supplements Wisely).
The sources we read do not say whether any of the nine Stallion Power ingredients interacts with nitrates. They do say that L-arginine and tribulus may add to the effect of blood pressure medicine (MSK, Arginine) (MSK, Tribulus terrestris). That is a reason to ask, not a finding of harm. See the medicines guide for the full picture.

See packsWhat to do before you buy
- List your medicines. Include nitrates under the tongue, patches, sprays and pills.
- Ask a pharmacist. Bring the bottle or the label. Say you take nitrates.
- Do not stop a medicine on your own. NIDDK says to talk to your clinician first (NIDDK, ED treatment).
- Skip products with an FDA warning. Search FDA notices before you buy anything from an unknown seller.
- Report problems. FDA accepts adverse event reports through MedWatch (FDA, X10 hidden-drug notice).
Call emergency services for chest pain, fainting, an erection lasting longer than four hours, or sudden loss of vision or hearing (MedlinePlus, Sildenafil).
Where Stallion Power fits
The label lists nine plant and amino acid ingredients plus 5 mg of caffeine. It lists no drug. We cannot say the bottle is free of hidden drugs, because we hold no lab report. Seller references such as a lot number are not lab proof. Read how we handle this on the tainted products guide.
Your next step is simple. If you take nitrates, call your pharmacist before you order. Keep taking your prescribed medicine.
