LA researchers say six popular peptides lack real evidence for injury recovery

Becker's Spine Review is covering a study out of LA that basically said the six peptides people talk about most for soft tissue recovery have very little solid evidence behind them. I'm not surprised honestly, to be fair most of what we rely on is rat data and small human case series.

What I keep coming back to though is that absence of evidence isn't the same as evidence of absence, especially for stuff like BPC where the mechanism makes biological sense and the human anecdotal signal is pretty loud. The bigger issue to me is dosing, duration, and quality of compounded product, not whether the molecule itself does anything.

Anyone else feel like the bar for "evidence" in this space is kinda unfair compared to what gets passed for PRP or even PT protocols?

  • cycles_dad: Yeah I saw that piece. The "six most popular" framing bugs me a little... BPC, TB-500, GHK-Cu, GLOW, ipaamorelin, and I think they threw in semax or selank even though those are clearly not injury-recovery peptides. Lumping cognitive stuff in there dilutes whatever point they were making imo 🔬 And yeah, absence vs absence of evidence... That's the part most journalists skip past. The mechanism story for BPC (vascular, nitric oxide, fibroblast migration) is genuinely strong on paper, way strong
  • leah_vo2max: The semax/selank thing is exactly what bugged me too, like why would you throw cognitive peptides into an injury recovery review unless you're just trying to pad the list to make it look worse than it is. The PRP comparison is what really gets me though, to be fair PRP has maybe one or two decent RCTs in specific indications and the rest is just as messy as peptide data, but nobody writes scare pieces about that. Did you see if the study actually broke down outcomes by peptide or did they just
  • patient_codes: I get why the six‑peptide list feels off, throwing in nootropics like Semax muddies the injury‑recovery angle. For me, oral BPC‑157 helped my nagging Achilles after about four weeks, but I wonder if the benefit was just from consistent loading and better sleep.
  • leah_vo2max: Yeah they did kind of lump everything together, Semax has no business being on a soft tissue list. To be fair the sleep angle is a good call, I sleep way better on BPC arg and never really thought about that being part of why my Achilles felt less angry by month 3.
