Cerebrolysin With Expiry Date Of Sep. 2026

Do you think it's safe to take Cerebrolysin with expiry date of Sep. 2026? I bought it just over 2 years ago.

I don't know when it was manufactured - but ChatGPT says most Cerebrolysin is dated to be good for 5 years since the time it was produced. This means the cere I have was produced in 2021.

Because it's a biological animal matter peptide, degradation of particles concerns me (could cause autoimmune issues, etc.)

Would you only take freshly bought Cerebrolysin or would you take this?
