Is the product quality guaranteed?

Does this product have to be refrigerated? Thank you

Usually when I buy this product they are kept refriderated, , they say to refridgerate after opening, can it harm product if already refriderated?

Will product effectiveness be diminished because it is shipped unrefrigerated by Amazon?
