TB-500 injection site irritation – what helped me reduce it

Posted by sleep_coastal in Safety & Side Effects - 7 points, 4 comments.

I started adding TB-500 to my GLOW stack a few months ago hoping for better recovery after long rides. Anecdotally the first few injections left a small red bump that stayed tender for about a day. I figured it was just the needle but it kept happening even when I switched to a finer gauge.

Anecdotally I noticed the irritation was worse when I injected into the same spot on my abdomen two days in a row. After reading a bit about tissue trauma I started rotating sites more aggressively – moving between abdomen thighs and love handles each session. I also started icing the area for thirty seconds right after the pinch and that seemed to calm the flare‑up faster.

Anecdotally the bumps are now barely visible and gone within a few hours. If you’re seeing similar irritation try rotating more and maybe a quick cold compress – it’s helped me keep the stack going without skipping doses. Let me know if anyone else has found other tricks that work.

  • fasted_scientist: Rotating sites is just basic subcutaneous hygiene though, that should be standard from day one not a fix you stumble onto. Ngl the icing bit is interesting, I've not tried that myself. I got similar bumps with BPC-157 and they settled once I started pinning further from my belly button where there's less dense tissue. Could just be that area is more reactive for some people. Have you considered it might be the bacteriostatic water or even the vial concentration rather than the needle? Higher co
  • grinder_busy: Fwiw I had the same thought about concentration, when I diluted my TB-500 more the stinging was noticeably less for me. Could just be placebo though, never did a proper side by side. The bacteriostatic water angle is worth looking into actually, has anyone here switched brands of bac water and noticed a difference? Seems like that would be the cleaner way to test it.
  • sleep_coastal: The dilution thing is interesting, I never played with concentration. I was running 2mg in a standard vial so maybe that was on the higher side for the volume I was pulling. The bac water brand angle is smart though, that would isolate the variable way better than what I did. I just changed two things at once, rotation and icing, so I can't even say which one did the heavy lifting. Did you go with a lower concentration per injection or just more total volume in the syringe?
