King Kong Honey: FDA found undeclared tadalafil
FDA testing found undeclared tadalafil in Miracle Power of King Kong Honey. What the warning says, who faces added risk and what buyers should do.
The name sounds like a simple honey product. FDA laboratory testing tells a more serious story: on September 25, 2026, the agency said Miracle Power of King Kong Honey contained tadalafil that was not listed on the label. FDA advises consumers not to buy or use this product. [1]

What FDA actually found
FDA described the product as promoted for sexual enhancement on websites including usroyalhoney.com and possibly in some stores. Its laboratory analysis confirmed tadalafil in the tested product. The notice does not give an amount, identify a lot number, or establish that every package from every seller has the same contents. [1]
Why an undeclared medicine matters
Tadalafil is the active ingredient in the prescription medicine Cialis. FDA warns that it can interact with nitrates, including nitroglycerin, and lower blood pressure to dangerous levels. The Cialis prescribing information likewise contraindicates use with nitrates because tadalafil can amplify their blood-pressure-lowering effect. That risk is especially relevant for people with diabetes, high blood pressure, high cholesterol or heart disease who may take nitrate medicines. A honey-style package does not make a hidden drug predictable or safe. [1][3]
If you bought or used it
Follow FDA's advice not to use the product. If you have taken it, especially with a nitrate medicine or another prescription drug, contact a healthcare professional or pharmacist promptly and show them the package. Do not stop or change prescribed medicines on your own. For severe symptoms, seek urgent medical care. Suspected side effects can be reported to FDA through MedWatch. [1]
What this warning does not prove
The FDA notice is about this named product and its laboratory finding. It does not establish what every seller knew, the tadalafil dose in every sachet, or the safety of all honey products. Japan's official HFNet separately catalogued the FDA alert and said no domestic adverse-event cases had been publicly reported as of September 29, 2026; that date-specific absence is not evidence that the product is safe. FDA also says it cannot test every product sold as a supplement. [1][2]
Did FDA find tadalafil in King Kong Honey?
Yes. FDA says laboratory analysis confirmed tadalafil not listed on the label of Miracle Power of King Kong Honey. [1]
Can it be safely combined with heart medication?
Do not assume so. FDA warns about dangerous blood-pressure drops when tadalafil is combined with nitrates. Ask a healthcare professional about possible exposure and your medicines. [1]
Our recommendation
We do not recommend Miracle Power of King Kong Honey. FDA found an undeclared prescription drug ingredient and directly advises consumers not to buy or use it. [1]
