Undeclared Sildenafil and Tadalafil in Recalled Supplements Pose Life-Threatening Risk to Consumers Taking Heart or Blood Pressure Medications

Consumers who purchased MR.7 SUPER 700000 capsules expecting a natural male enhancement supplement are now facing alarming risks. The U.S. Food and Drug Administration (FDA) has issued a public health warning and product recall after laboratory tests confirmed that these capsules contain undeclared prescription drugs sildenafil and tadalafil, the active ingredients in Viagra and Cialis.

Manufactured and distributed by StuffbyNainax LLC, these capsules were sold online across the United States between August 2025 and November 2025. The FDA warns that people taking prescription medications, particularly those involving nitrates for heart disease, diabetes, or high blood pressure, could suffer life-threatening interactions from unknowingly ingesting these hidden substances.

Consumers who used MR.7 SUPER 700000 may be entitled to legal compensation, especially if they experienced serious side effects or required hospitalization after use.

Understanding the Recall: Why the FDA Took Action

The recall was announced after FDA laboratory analysis revealed that MR.7 SUPER 700000 capsules contain sildenafil and tadalafil without disclosing these ingredients on the label. Both are prescription-only drugs regulated by the FDA and approved for the treatment of erectile dysfunction.

The manufacturer, StuffbyNainax LLC, has voluntarily recalled all lots of the product, although the capsules had no visible lot numbers or expiration dates, making tracking extremely difficult for consumers.

The FDA’s concerns are serious and specific:

  • Undeclared ingredients violate federal labeling and safety laws.
  • Sildenafil and tadalafil can dangerously interact with nitrates found in heart and blood pressure medications.
  • The resulting interaction can cause a rapid and severe drop in blood pressure, which may lead to shock, stroke, or even death.

Because the product was sold exclusively online, many consumers may have purchased it without ever speaking to a medical provider or knowing about these risks.

What Makes Sildenafil and Tadalafil So Dangerous Without Warning Labels?

Sildenafil (Viagra) and tadalafil (Cialis) are safe when prescribed and monitored by a healthcare professional. However, when these drugs are hidden in unregulated products, the risk to the user’s health increases significantly.

Here’s why:

  • Sildenafil and tadalafil both act as PDE5 inhibitors, affecting blood flow. When combined with nitrates — which are commonly prescribed to patients with coronary artery disease, angina, or high blood pressure — the interaction can result in a catastrophic drop in blood pressure.
  • Consumers with diabetes, high cholesterol, or cardiac history are more likely to be taking these nitrate-based drugs.
  • Without knowing that they are ingesting sildenafil or tadalafil, these individuals are unable to avoid these dangerous combinations.

The situation becomes even more hazardous because MR.7 SUPER 700000 had no identifying lot numbers, expiration dates, or full ingredient disclosures. That makes tracking use and reporting side effects much more difficult for medical professionals and patients alike.

Distribution and Reach: Who May Be Affected

According to the FDA, MR.7 SUPER 700000 was sold:

  • Nationwide, via online platforms, including e-commerce websites and possibly third-party sellers.
  • During a short window: from August 2025 to November 2025.
  • Under the brand name MR.7, with no batch or lot number, making product identification difficult.

Anyone who purchased male enhancement capsules labeled as MR.7 SUPER 700000 during this timeframe — even if they no longer have the packaging — may have been exposed to prescription-strength erectile dysfunction medications without knowing.

Due to the widespread nature of online sales, it’s likely that thousands of individuals across the country could be at risk.

Health Risks Associated with MR.7 SUPER 700000

The health risks posed by these undeclared substances are significant and may include:

1. Sudden Blood Pressure Drop

When sildenafil or tadalafil interacts with nitrates, the user may experience a dangerously low blood pressure episode. Symptoms may include dizziness, fainting, nausea, chest pain, or confusion.

2. Cardiovascular Collapse

Patients with heart conditions may suffer cardiac arrest, arrhythmias, or complete cardiovascular shutdown when exposed to PDE5 inhibitors unknowingly.

3. Stroke or Ischemic Injury

Reduced blood flow to the brain caused by hypotension can lead to stroke, brain injury, or death.

4. Severe Drug Interaction Events

Patients taking medications such as nitroglycerin, isosorbide dinitrate, and similar compounds may suffer unexpected drug interactions that require emergency care.

5. Unknown Dosing Risks

Even healthy individuals not taking other medications may face problems. Because the concentration of the undeclared ingredients is unregulated, users may be ingesting dangerously high doses, leading to side effects like:

  • Vision disturbances
  • Headaches
  • Prolonged or painful erections
  • Muscle aches
  • Sudden hearing loss

Legal and Consumer Protection Issues

This recall raises major concerns about consumer deception and unsafe practices in the unregulated supplement market. Selling a product as a “natural supplement” while it secretly contains powerful prescription drugs violates federal law.

Possible legal claims may include:

  • Product liability for defective or misleading labeling
  • Negligence in manufacturing and marketing
  • False advertising or consumer fraud
  • Personal injury due to adverse health events

Consumers who suffered serious health complications after using MR.7 SUPER 700000, especially those hospitalized or needing emergency treatment, may be eligible for financial compensation.

Additionally, family members of deceased users may have grounds for a wrongful death lawsuit if the supplement caused or contributed to the fatality.

What Should You Do if You Used MR.7 SUPER 700000?

If you used this product between August and November 2025, you should take the following steps immediately:

  1. Stop using the product.
  2. Consult your physician if you experience any side effects or have concerns about drug interactions.
  3. Keep the bottle and packaging, if available, for documentation.
  4. Check for any medical records related to side effects, ER visits, or symptoms after taking the supplement.
  5. Contact a product liability attorney to explore your legal options, especially if you experienced significant health problems.
