TFA VG/PG Dilutant Query

[Beeker]

Anyone have experience with TFA Bulk Diluting Liquids (PG/VG). Their site lists both as USP Grade but is it 'Pharmaceutical Grade' or just 'Food Grade'. I've been using their flavors for years and can't imagine them buying/using anything other than Food Grade carriers for their VG/PG based flavors. Very interested since they still ship USPS, UPS and FEDEX and don't seem affected by the PACT ACT since they only sell Flavors and such.

I'm down to my last bottles of Wizard Labs PG/VG I froze in 2022 but still have plenty of 100mg nic salts in the freezer.

Any comments or warnings appreciated.

USP grade is pharmaceutical grade, which inturn, follows strict purity standards. Food grade products don't have to follow those same guidelines. Instead, they simply need to be generally recognized as safe (GRAS) for humans to consume, which may, or may not, include inhilation.
