Great Service and Product

Hard to find this version of an old standby product that works wonders for my symptoms. Very pleased to find it here, reasonably priced. First time customer, but not last time. Service was and delivery was flawless with great communication.

Sometimes, for a bad headache, you need something different from the usual remedies. Works for me. Glad I found them at BEYONDRx.
