The article makes the point that despite human trials originally, and later one-cell zebrafish embryo tests, no sign of carcinogenesis was detected. They further explain that given its limited range within the body, it only impacting damaged tissue and the short period of time it would be used, it’s unlikely to be carcinogenic.

Oh sure, this agrees with the "tightly regulated" constraint. Short time, localized application/expression qualify. I'm not sure that long term exposure would be good, and in reference to BPC-157 let's not forget that intestinal cancers do occur (though I'm not at all sure if there's ever been a link between BPC-157 and intestinal cancer).

It's great that the compound looks safe given the limited amount of information we have, but it sounds like there's not a whole lot of trials out there with the power to test the possibility that this could be cancerous long term. Happy to be proven wrong though!

Remember the initial human trials were using it systemically to control blood sugar, and specifically looked for carcinogenesis. Obviously there’s room for something to have been overlooked, but in the narrow case of this particular molecule I’d be hopeful. As for BPC-157 we’re very much on the same page, and I’d be very concerned about cancer.

Oh interesting, I'd missed that. Thanks for the note!
