I visited my physician when experiencing my usual seasonal allergy and cold symptoms. He suggested Stahist AD as a remedy for my sinus pressure and congestion. I give Stahist AD two thumbs up for providing fast relief!

Dave from Ft. Wayne, IN


Stahist AD is the only allergy product that works for me. I only take it once a day and it really dries up my post nasal drip. I have tried everything else out there and nothing works as well as Stahist AD. Inexpensive as well.

I take Stahist AD daily for my year round allergies. I have had allergies since I was a kid and have taken every product on the market. Stahist AD has been the ONLY product that has worked for me. It does not make me drowsy, provides relief fast, and prevents sinus headaches.
