My experience using PBS instead of bacteriostatic water for peptide reconstitution

I’ve been reconstituting most of my peptides with bacteriostatic water for years, but lately I ran out and decided to try phosphate buffered saline (PBS) just to see if anything changed. I used the same volume I normally would, aiming for the target concentration written on the vial. The solution looked clear and there was no precipitation, which was a relief.

Over the next week I tracked how I felt after my usual doses of BPC‑157 and TB‑500, noting any differences in soreness after training or sleep quality. For me, the effects seemed about the same – I didn’t notice extra stiffness or any unusual fatigue. I did wonder if the isotonic nature of PBS made the peptides a bit more stable during storage, but I didn’t run any formal tests, just my own notes.

Has anyone else tried PBS as a diluent and noticed anything different, good or bad? I’m curious if it’s worth keeping on hand as a backup. No?
