Query: It's aspirin.

How do you tell if a low dose aspirin is doing its job? I'm taking it to avoid a stroke or heart attack and I'm still here.Aspirin is aspirin and the price is right, the delivery was normal.It has the easy to swallow coating so you don't even need water or just pop it in between your lips with some chewed food just before you swollow.
