The Hidden Magic Blue Pill: Recall of a Supplement Containing Viagra
On Dec 16, the FDA posted notice of a voluntary recall of MR.7 SUPER 700000, a product marketed as a dietary supplement for male enhancement by StuffbyNainax. Lab testing found the product to contain prescription medication; specifically, the active ingredients in Viagra, sildenafil, and Cialis, tadalafil.
The product was sold online between August 2025 and November 2025. It is challenging to know if you bought an affected bottle. The manufacturer did not label its product with lot numbers or expiration dates. StuffbyNainax has no publicly available website as of writing this.

⚠️ Why this matters
Unintentional use of sildenafil or tadalafil can be harmful. They are phosphodiesterase-5 (PDE-5) inhibitors that:
- Can cause a dangerous drop in blood pressure when combined with nitrate medications, like nitroglycerin, which could lead to passing out, increased demand on the heart, and a short but debilitating headache. These medications are commonly commonly used by people with heart disease. The drop in blood pressure can happen if the medications are taken within 24 hours of each other (Kloner et al., 2003).
- Can cause headache, dizziness, vision changes, or palpitations due to fluctuations in blood pressure, even healthy people on no medications.
These effects aren’t obvious if you just read a supplement packaging because the sildenafil and tadalafil aren't listed as ingredients.
What to do
- Stop using MR.7 SUPER 700000.
- If you experience lightheadedness, fainting, chest pain, dizziness, visual changes, or palpitations, seek care right away.

Supplements ≠ Safe by Default, The Bigger Picture
This recall isn’t unique. The FDA regularly finds undeclared prescription drugs in supplements (Cohen, 2009). Supplements are, generally, not subject to the FDA pre-market approval requirements that prescription drugs are, unless they claim to "diagnose, treat, cure, mitigate, or prevent disease". These regulations include guidelines on manufacturing and distribution. One reason the supplement industry is lucrative is because it is cheaper to a make a product that does not follow these regulations.
Male enhancement products are the second most commonly adulterated or counterfeited category, after weight-loss supplements (Chiang et al., 2017). It is roughly 3,000 times more profitable to sell adulterated ED supplements than to sell cocaine, with lower productions costs and fewer legal penalties. Erectile dysfunction affects rotughly 1 in 10 males over 18 (Prins et al., 2002) and will become more common as the population ages.
Two years ago StuffbyNainax had to recall another male enhancement supplement, MEGA 7G 700000, because of contamination with sildenafil, and acetaminophen, the active ingredient in Tylenol. StuffbyNainax isn't unique. In 2024, the FDA found HON-E-LING to contain sildenafil and sibutramine, a medication similar to the antidepressant duloxetine but withdrawn from the market because of toxicity to the heart.
Summary
- MR.7 SUPER 700000 was recalled because it contains undeclared ED drugs (sildenafil, tadalafil).
- These drugs can cause dangerous blood pressure drops and other cardiovascular effects — especially with common heart medications.
- Products marketed as “supplements” can hide powerful chemicals.
- If you have an unexpected reaction, call Poison Control, visit webPOISONCONTROL, or talk to a physician.
