Hello. I received N some days ago. Unluckily I couldn't bring the parcel home until late at night to avoid me and the parcel to be scrutinized by my family members... So I kept the parcel with N in my car from noon to night. Car has been under the sun several hours in the afternoon. External temp was already very high (+30°C) so I imagine inside the car it would have been hot. At the moment I hadn't thought of this but now I am very worried that N can be "rotten" or have lost efficacy. Any help is really appreciated.
