Use of PN as backup to SN

[Wish2Exit]

I have 25mg only of sodium nitrite as my primary ctb method, which is plenty based on my bodyweight. I have plenty of potassium nitrite as my secondary in case the primary is not enough/does not work. Does anyone know of any reason to not take the PN, such as if the two will interact in a way to make them ineffective? Thanks.

There is a GBT. They used PN (KN) instead of SN. You can use the search. I don't have the link at hand rn.
