PG Spray - Expires?

[Debbiefish]

Good morning!

Question about PG Spray - if opened or still sealed...does PG Spray expire? Same with the B-12 spray?

Thanks for any info.

Per Casey in a post yesterday about PG spray :

All T-Tapp brand supplements (Alfalfa, Fibertox, PG, B-12, Immune Boost) have a 3-5 year shelf life
