I had some PT-141 that was around 2 years old.* It had always been refrigerated but still 2 years is a long time.* Anyway I finally talked my DW into taking some this past Valentines day.* Ow man it was like a bee sting it hurt so bad.* Now the good news is it still worked perfectly since we did it like 6 times in 9 hours and she said every thing felt better.
She wanted to try it again but did not want to fell the sting.* I order a new batch and no sting at all.*
