Tb-500 after hamstring strain: timing with physical therapy sessions

Posted by retiredfreya in Healing & Recovery - 1 points, 2 comments.

I had a pretty bad hamstring strain last month after a sprint. I started tb‑500 4 days after the injury, 2 mg twice a week for the first week, then 1 mg once a week. To be fair i was also doing physical therapy two days a week and doing light stretching.

I noticed that my pain went down quicker than i expected, and by week three my range of motion felt almost normal. The question i have is about timing: i usually inject tb‑500 in the evening, then do therapy the next morning. Does that affect the peptide’s ability to work on the tissue?

I’ve read that the peptide’s half‑life is about 6 hours, so i was wondering if injecting right before therapy might reduce absorption or if it’s better to do it a few hours after. I also reconstituted the vial with acetic acid water because the powder was a bit stubborn to dissolve, and no stinging at the injection site. Any practical advice from others who’ve paired tb‑500 with structured rehab would be appreciated. Thanks in advance.

  • vet_travis: I’ve done a similar thing with a minor calf tweak – I injected tb‑500 the night before my physio session and didn’t notice any change in how the session felt compared to when I jabbed it a couple of hours after therapy. The half‑life is short, so most of the peptide is cleared by the next morning anyway, but I reckon the timing isn’t make‑or‑break for the tissue response. I’m curious though – did you keep a log of pain scores or ROM measurements each week? That might help tease out whether the
  • retiredfreya: I kept a very simple log – pain 0‑10 each day and my hamstring flexion in degrees on a paper chart. I noted a drop from 8 to 3 over three weeks, and ROM went from 130° to 160°. I didn’t see a sharp jump right after the first injection but it seems steady. Do you notice any pattern with a “before vs. After” injection in your calf tweak? That would be helpful.
