Using PBS to reconstitute BPC-157 for subQ injection – any issues?

Posted by tracker_jade in Healing & Recovery - 1 points, 0 comments.

I’ve been mixing my BPC-157 with bacteriostatic water for subQ shots but ran out and only have phosphate buffered saline on hand. Has anyone tried using PBS as the diluent? I’m wondering if it changes the stability or causes more irritation at the injection site.

Anecdotally, I’ve read that PBS keeps the pH near physiological which should be gentle on the peptide, but I’m not sure if the salt load could affect absorption or cause any weird swelling. I’m currently using it for a nagging elbow tendon issue and doing light rehab bands twice a week. If you’ve used PBS, did you notice any difference in how quickly you felt relief or any side effects like redness or itching?

Also, do you keep the mixture in the fridge and use it within a certain time frame? Just looking for real world feedback before I stick with it. Thanks.
