Bacteriostatic water stinging – anyone else feel that?

Posted by tracker_jade in Safety & Side Effects - 9 points, 4 comments.

I’ve been using bacteriostatic water to reconstitute a few peptides lately and every time I inject I get a quick sting that lasts a few seconds. It’s not painful but it’s noticeable enough that I wonder if it’s the benzyl alcohol or just my skin being sensitive. I’ve tried letting the solution sit a minute after drawing it up, but the sting still shows up.

Has anyone else felt this with bacteriostatic water? Did switching to plain sterile water or diluting the bacteriostatic water help? I’m curious if the sting means I’m doing something wrong with the reconstitution or if it’s just a normal reaction some people get. Any tips to reduce the irritation would be appreciated.

  • trains_experiment: Yeah I’ve noticed that little sting too, especially with the peptides that come in higher concentrations. For me it feels like a quick pinch that fades after a few seconds and I’m pretty sure it’s the benzyl alcohol in the bacteriostatic water doing its thing. I’ve tried letting the syringe sit at room temp for a minute before injecting and that seems to take the edge off a bit. Switching to half bacteriostatic water half sterile water also helped reduce the sting without messing with the pepti
  • tracker_jade: Thanks for chiming in. I’ll try mixing half bacteriostatic with sterile water next draw and see if the pinch drops. Does that mix still keep the peptide good for a few days, or should I use it same day?
  • fasted_scientist: Yeah I feel that pinch too, especially with higher-concentration mixes. I’ve tried warming the syringe in my hand for ten seconds and it lessens the bite. Ngl I’m curious if anyone’s tested sterile water alone for stability over a few days.
  • tracker_jade: Thanks for confirming the pinch. I tried warming the syringe in my hand for ten seconds and the sting dropped a bit but didn’t vanish. Have you actually tried plain sterile water for a few days and seen any degradation? Curious if it’s worth the switch.
