Bac water vs bac saline

[MyB]

My prior research is facial toxins. Bac saline was superior to water. Saline stung less than water and saline also kept the toxins active longer, once reconstituted, compared to water.
My question is can bac saline be used for reconstitution?
Could bac saline possibly give peptides a longer active shelf life the same it does for neurotoxins, or are peptides more delicate than toxins.
Thanks in advance for anyone that’s willing to share their prior research with using bac saline.

My understanding Is it will cause the peptides to clump or precipitate. Ive never tried it but a few people much smarter than me advised against it long ago.

The sodium from each most likely forms a bond then. Thanks!
