TB4-Frag daily vs TB-500 2x/week for a nagging rotator cuff, anyone done both?

Posted by tracker_jade in Healing & Recovery - 7 points, 6 comments.

Got a rotator cuff thing that's been hanging around since like February. PT helped some but it stalled out. I ran TB-500 a while back for a different injury, did 2mg twice a week for about 5 weeks then dropped to once weekly. Anecdotally that seemed to help with inflammation but it took maybe 3 weeks before I noticed anything.

Now I'm looking at TB4-Frag since the dose schedule is different, more like 200-750 mcg daily or every other day. Shorter half-life so that makes sense. Just wondering if anyone here has actually used both for the same type of injury and noticed a difference in how fast things kicked in or overall results.

The daily pinning thing kinda annoys me but if it means better tissue penetration for a stubborn tendon I'd deal with it. The full TB-500 seemed more systemic to me, like general recovery vibes. Did the fragment feel more targeted for anyone?

Also curious about stacking it with BPC-157 injectable near the site. I did oral BPC last time for gut stuff while running TB-500 and that felt like two separate things working independently. Not sure if local BPC plus TB4-Frag would be redundant or actually complementary for tendon repair. Anyone tried that combo?

  • paige747: I've done both but not for the same injury so take this with a grain of salt... Tb-500 felt more systemic to me too, like general soreness just faded. Tb4-frag daily felt more like it was actually doing something at the site but tbh that could just be because i was pinning near it and paying more attention. Kicked in maybe 10 days-ish vs the 3 weeks you mentioned with full tb-500. On the BPC combo, i ran local BPC-157 with tb4-frag for a pesky elbow thing and they felt complementary not redunda
  • curious_scientist: The "felt more at the site" thing is interesting because tb4-frag is still systemic, it just has a shorter half-life so you get more sustained exposure with daily pinning. Imo the site-specific feeling might really just be the attention bias thing you mentioned. But the faster onset tracks with what I'd expect from keeping levels more stable vs the peaks and troughs of twice-weekly dosing. The BPC pairing making sense biologically too, they're hitting different pathways. BPC is more acute anti-
  • curious_scientist: The "pinning near it so you notice more" thing is real, I caught myself doing the same thing. Hard to separate actual localized effect from just being hyper-aware of that spot. But the faster onset matches what I'd expect with daily dosing keeping levels more steady vs the peaks and troughs of twice weekly. The BPC plus TB4-frag layering makes sense to me too, acute vs remodeling. Did you space the two pins apart or do them together?
  • tracker_jade: Yeah I was gonna layer BPC-157 with it, figured the daily BPC for acute inflammation and the TB4-Frag for the longer remodeling phase. I'd probably space them a few hours apart just because I don't love mixing two compounds in one pin, but honestly I don't know if that matters at all. Did you do them together when you ran that combo?
  • tracker_jade: Yeah the attention bias thing is probably fair, I caught myself checking that shoulder constantly so who knows. The stable levels vs peaks and troughs explanation makes more sense to me than any targeted effect honestly. Did you run the BPC alongside TB4 at the same time or stagger them? Wondering if starting BPC a week before the TB4-Frag would let the acute inflammation calm down first before hitting the remodeling side.
  • tracker_jade: The 10-day kick-in is interesting, that's a lot faster than what I experienced with the full TB-500. Makes me think the daily dosing actually keeps levels steadier instead of the peaks and troughs from twice a week. And yeah the "pinning near it and paying more attention" thing is fair, could just be bias. On the BPC combo, did you run the BPC subQ near the joint or actually into the tendon area? I've only done subQ before and wondered if it matters much for something like a rotator cuff where
