Purnail is an expensive scam, likely rebranded Fungisil snake oil

Purnail is a toenail product to treat nail fungus. It’s active ingredient, undecylinic acid is available for about 1/40th the price at your local CVS!

For example, $13 for 1 ounce of 25% undecylinic acid in Fungicure vs $60 for 0.3 ounces of 10% undecylinic acid in Purnail.

Purnail is a scam. I’d like to give you better news but modern science doesn’t have a cure-all for nail fungus. Feel free to browse my site for ongoing real discussion about nail fungus cures.

Short form: orals sometimes (50%?) work but they can be toxic to your liver. Any topical has a low (10%?) chance of success at curing. Some people say one formulation has done better for them than others. Don’t hold your breath and don’t spend a ridiculous amount of money on treatments: if it seems to good to be true, it is. Keeping your infection at bay with an inexpensive topical might be the best you can do.

Purnail is almost definitely just a rebrand of another product made with the same ingredients with the same bottles and the same marketing. Take a look at the two product pages, do you notice any similarities?
