bud

I have some Preg capsule at home from Empower, BUD was 05-2023. I'm wondering if potency is still ok or it has been lost substantially, what do you guys think? toss it?

Let's say it is unopened, in a closed box not near sunlight, at room temperature. Is there a certain point it tends to get "weaker"? One year after the BUD? Two years after? Right away? Same question regarding AIs. Any data in regards to AIs as well?
