Expired Supplements

Expired Supplemets

Title, some of the supplements are ON whey protein, animal STAK, animal M-STAK, N.O xplode, animal cuts., cell tech. ALL of the supplements were stored in dark place and were not exposed to sun at all, but sometimes the room temperature was high. The most expiry date is 2020, and I have not opened any of them. Some expired in 2021, 2020 and some expired 6 months ago

Is it safe use these supplements or not? And what is the maximum duration after which I can not use the supplements? Does the type differ I mean the creatine, for example, can be used and the proteins not?

Thanks
