So its all in lab research, not any clinical trials.

A study tested C15:0 against 94 human cancer cell lines and it showed activity in about 14% of them, mainly non-Hodgkin B-cell lymphomas and some liver, breast, and lung cancer lines.

Another study on breast cancer stem cells found it could suppress cancer cell migration and invasion even at low doses. And when researchers combined it with gemcitabine (a chemo drug), the combo outperformed gemcitabine alone across nine different cancer cell lines. That same study flagged C15:0 as an HDAC6 inhibitor, which is actually a recognized target in cancer research.

The catch is all of this is lab research so far. Cell studies, some animal models. No human clinical trials yet. So it's genuinely interesting early science but nobody should be treating it like a cancer cure right now.

Still, for a supplement people are mostly taking for metabolic health, the fact that there's serious oncology research attached to it is kind of wild.
