BA & WA water (bacteriostatic water)

I have serious questions. I did my research but I want to hear it from personal experiences.

What’s the difference in shelf life of peptide when mixed with WA (st3rile water) or BA (B3nzyl Alch0l)?

Is my Trizep useless or will no longer take effect if I have mixed it with WA? 🥹 I’ve been searching and sterile water is supposed to be one time use. So if I mix my 15mg with WA I need to throw it away? 😭😩 halpppp
