Tainted Male Enhancement Products: What the FDA Has Found
The FDA has warned about sexual enhancement products that contained sildenafil and tadalafil, the drugs in Viagra and Cialis, without listing them on the label. Those hidden drugs can lower blood pressure to dangerous levels in men who take nitrates. A label cannot prove a product is clean. Treat the whole category with care and ask a doctor first.

The warnings01
What does the FDA say about tainted sexual enhancement products?
The FDA has tested products sold for sexual enhancement and found prescription drugs that the label did not list.
In a notice dated May 29, 2026, the FDA said its laboratory analysis found sildenafil and tadalafil, not listed on the label, in a product sold for sexual enhancement. The agency advised consumers not to buy or use it (FDA, X10 hidden-drug notice). An older notice, dated 2015, described the same pair of drugs in a different product that had been identified through international mail shipments (FDA, Wild Sexx hidden-drug notice). Sildenafil and tadalafil are the active ingredients in Viagra and Cialis (FDA, Wild Sexx hidden-drug notice).
The NCCIH confirms the pattern. It says some products marketed for weight loss, sexual enhancement or bodybuilding may contain prescription drugs not allowed in supplements, or ingredients missing from the label, and some may be unsafe (NCCIH, Using Dietary Supplements Wisely).
| Notice | Date | What FDA found |
|---|---|---|
| X10 | May 29, 2026 | Sildenafil and tadalafil, not on the label (FDA, X10 hidden-drug notice) |
| Wild Sexx | 2015 (the page shows conflicting dates) | Sildenafil and tadalafil, not declared (FDA, Wild Sexx hidden-drug notice) |
Both notices are about one named product each. Neither says anything about Stallion Power, and no source we read says Stallion Power holds a hidden drug. The two notices show a pattern in the category, not a fact about this gummy.
What turns up02
Which drugs are most often found hidden in supplements?
In the two FDA notices we read, the hidden drugs were sildenafil and tadalafil (FDA, X10 hidden-drug notice) (FDA, Wild Sexx hidden-drug notice). Both are prescription medicines for erectile dysfunction. We did not read the FDA's full database, so we cannot say how often other drugs appear in this category.
Outside sexual enhancement, the NCCIH says the FDA has found prescription drugs such as warfarin and phenytoin in products sold as supplements (NCCIH, Using Dietary Supplements Wisely). The point is general: a supplement label does not guarantee that the bottle holds only what it lists.
Sildenafil should not be taken with nitrates for chest pain, such as nitroglycerin (MedlinePlus, Sildenafil). The FDA says the hidden drugs may interact with nitrates and lower blood pressure to dangerous levels, and that men with diabetes, high blood pressure, high cholesterol or heart disease often take nitrates (FDA, X10 hidden-drug notice). A man who does not know he is taking an ED drug cannot know he is at risk.
Read more on the nitrate danger in the supplements and medications guide.
The gap03
Why are hidden drugs not listed on the label?
By definition, a hidden drug is one the seller left off the label. The FDA notices we read do not explain why a seller would do that, and we will not guess at motives.
The structural reason is simpler. The FDA does not approve dietary supplements before they are sold, and does not approve supplement labeling (FDA, Q&A on dietary supplements). Companies carry the first responsibility for making sure their products are not adulterated and for having evidence behind their claims (FDA, Q&A on dietary supplements). Checks mostly come after a product is already on the market.
Gummies are not immune to label problems of a different kind. A 2023 JAMA study of 25 melatonin gummies found that 22 were inaccurately labeled, with measured melatonin ranging from 74 to 347 percent of the labeled amount (Cohen 2023, JAMA, Melatonin gummies). That study covers melatonin gummies only. It shows that a gummy can differ from its label, not that Stallion Power does.
A practical test04
How can I tell if a product is tainted?
You usually cannot tell from the label, the taste or the packaging.
Only laboratory analysis found the drugs in the FDA notices (FDA, X10 hidden-drug notice). A clean-looking label proves nothing. So the useful steps are about lowering your risk, and about what to watch for. This is our checklist, not an FDA test.
- Tell a doctor or pharmacist what you plan to take, especially if you use nitrates, blood pressure, diabetes or heart medicines.
- Buy through the official checkout, not from mail-order sellers you cannot trace. The 2015 notice involved products found through international mail shipments (FDA, Wild Sexx hidden-drug notice).
- Check the seal under the cap before you use it. The Stallion Power label says not to use the product if the seal is broken or missing.
- Read the label for lines such as sildenafil or tadalafil. The NCCIH says prescription drugs are not allowed in supplements (NCCIH, Using Dietary Supplements Wisely).
- Know that the seller's own lot and certificate references are not lab proof. See batch verify and testing and quality.
We have no laboratory result for Stallion Power. The label names no lab and no manufacturer. Treat it as you would any product in the category.
Checking the list05
Where can I check the FDA list of tainted products?
The FDA publishes warnings about tainted sexual enhancement products on its own website, and the two notices above are examples. We could not open the FDA's main list page when we researched this guide, so we cannot describe its contents or how often it changes. Search the FDA website for the page named Tainted Sexual Enhancement Products and check it yourself.
A product missing from the list is not proof that it is clean. The list reflects what the FDA has tested and published. Use it as one check among several, and look at the date on each notice.

What should I do if I took a tainted product?
Stop using the product and call a doctor or pharmacist. Get emergency care for danger signs.
- Stop using it. The label of Stallion Power also says to discontinue use and consult your doctor if any adverse reactions occur.
- Know the danger signs. Chest pain, fainting, an erection that is painful or lasts longer than four hours, and sudden vision or hearing loss need care right away (MedlinePlus, Sildenafil) (NIDDK, ED treatment).
- Keep the bottle. Keep the packaging, the lot number and the order email.
- Tell your clinician. Say what you took and which other medicines you use, nitrates above all.
- Report it. The FDA encourages reporting adverse events to MedWatch (FDA, X10 hidden-drug notice).
Keep taking your prescribed medicines unless a clinician says otherwise. For a Stallion Power order, the desk is at +1 (302) 200-3480 or [email protected], and the guarantee page explains returns.
Form factor07
Are gummies and chews also affected?
The two FDA notices we read were about products sold for sexual enhancement, and neither source says what form they took. We found no source that says gummies are safer, or riskier, than pills. The form of a product is not a safety signal.
What matters is the category and the seller. Nothing about a gummy proves it contains only what it lists. See how gummies compare with capsules and pills for the practical differences.
