The ED Drug Problem in Men's Supplements & Why VigRX Chose to Test First.

There is a specific, documented problem in the men's sexual health supplement category. The FDA has issued repeated warnings about it. Researchers who test these products routinely find it. And consumers who think they are buying a natural herbal product are often unknowingly ingesting prescription-strength drugs without any medical oversight.
The problem is adulteration.

What Adulteration Looks Like

Adulteration in men's supplements typically involves the hidden addition of PDE-5 inhibitors, the same class of drugs as Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil), or chemically modified analogues of those drugs. These analogues include compounds like acetildenafil, aminotadalafil, homosildenafil, hydroxyhomosildenafil, noracetildenafil, and others.

For most healthy men, taking these compounds might produce noticeable effects. For men taking nitrates for heart conditions, the combination can cause a dangerous and potentially catastrophic drop in blood pressure. The problem is the man has no idea what he is actually taking.

The supplement appears to work. The brand takes credit for the herbal formula. But the actual mechanism is pharmaceutical, and the risk can be life-threatening.

What VigRX Did About It

AIBMR Life Sciences sent a sample of VigRx tablet blend (Lot #120657) to Flora Research Laboratories in Grants Pass, Oregon, an independent analytical facility. The analysis was conducted using High Performance Liquid Chromatography (HPLC) according to ChromaDex Method CD-ATM-031-03-01 (modified).

The test screened for sildenafil, vardenafil, tadalafil, acetildenafil, and compounds with similar spectral profiles to known ED drug analogs, using a dual-column method with photodiode array detection and mass spectrometry confirmation to maximize screening sensitivity.

Results: Sildenafil, Vardenafil, Tadalafil, and Acetildenafil were not detected in the sample. Further, compounds with similar spectra to known ED drug analogs were not found in the chromatogram.

The report was prepared and signed by James Neal-Kababick, Director of Flora Research Laboratories, on March 2, 2007.

Why an Independent Laboratory Matters

Any brand can claim their product is clean. What Flora Research Laboratories provided was an independently generated analytical report using validated chromatographic methods, not a company declaration.

This is one of several independent purity screenings VigRX has undergone. The companion study by Smitasiri et al. (2010) screened the same formula against 180 active pharmaceutical ingredients across 19 drug categories using a separate laboratory in Taiwan. Both returned clean results.

The Smitasiri et al. study noted that performing these analyses on finished product is the best way to determine that no adulteration occurred during any step of the manufacturing process, including steps the brand itself may not directly oversee.

What This Means for the Man Buying VigRX

There are two things a man needs to know about any supplement he is considering for sexual performance.

First, does it do anything? That is the efficacy question, and it is answered by the clinical and preclinical studies that VigRX has funded and published.

Second, is it actually what it claims to be? That is the purity question. The Flora Research Laboratories analytical report and the companion purity screens answer that. 

What is in the VigRX formula is the botanical blend it says it is. What is not in it are the pharmaceutical adulterants that compromise so many other products in this category.
