PNC-28 Reference

Plain English

What it is

PNC-28 is an experimental peptide, which is a small piece of protein. It is built from a part of a natural cell protein called p53. It is not an approved medicine and has only been looked at in the lab and in animals.

What people use it for

Online, PNC-28 shows up in fringe groups that talk about it as a possible cancer-fighting agent, often next to its close relative PNC-27. Any claim that it treats cancer in people is unproven.

What the science shows

In lab dishes, it killed several kinds of human cancer cells while leaving normal cells alone. In mice, it shrank or wiped out transplanted tumors. No studies have tested whether it works or is safe in people.

The catch

This is not a cancer treatment, and there have been no human trials, so its effects in people are unknown. Researchers treat any real-world anticancer claim as unproven and high-risk, and it is not a substitute for cancer care.

Reference summary

Older studies describe transformed-cell cytotoxicity and pancreatic-cancer-cell necrosis models. Human clinical efficacy data are absent.
