I think you got me confused with someone else as I am not sure which product you are referring to.In the leaflet it says you can use it up to 56 days after out of the fridge. It should arrive in under 1 month so you are left with 1 month. I doubt it stops working at all after the 56 day but maybe it looses potency slowly.
Last time I ordered from you and with express shipping I got my parcel in 4 days. Would love to repeat. Hope you have good news now about express shipping
