Frequently Asked Questions

Do you sell the product Stiff Nights?

Short Answer


Long Answer

Stiff Nights is being marketed as a safe natural herbal supplement for erectile dysfunction or as a lifestyle drug.

Actually it is a chemical similar to sildenafil (Viagra) but there has been no testing carried out to test the safety of either its short term or its long term use, and therefore potentially very dangerous to use.

The chemical name of the active ingredient is thio-sildenafil or thio-homosildenafil.

Both the US FDA and the Canadian Health Protection Branch warn against the dangers of using this product.

Additional Information

Canadians Advised Not to Use "Stiff Nights" or Any Unauthorized Product Promoted for Erectile Dysfunction
Health Canada is advising consumers not to use the unauthorized product "Stiff Nights" after the U.S. Food and Drug Administration (FDA) found that this product contains an undeclared substance similar to the prescription drug sildenafil and may pose serious health risks, particularly to people with heart problems. "Stiff Nights" is promoted as an "all natural dietary supplement" used for male sexual enhancement. Health Canada has confirmed that "Stiff Nights" is being distributed in Canada as well.
FDA Warns Consumers on Sexual Enhancement Products

The U.S. Food and Drug Administration is warning consumers that Stiff Nights, a product marketed as a dietary supplement for sexual enhancement, contains an ingredient that can dangerously lower blood pressure and is illegal.

Over the past several years, the FDA has found many products marketed as "dietary supplements" for sexual enhancement that contain undeclared active ingredients of FDA-approved drugs, analogs of approved drugs and other compounds that do not qualify as "dietary ingredients." The FDA has issued multiple alerts about these contaminated dietary supplements.
