Lab & animal research
Results shown in lab & animal research
- What the science shows
- In a 2023 mouse study of damaged heart muscle, B7-33 was put to the test against fibrosis, the stiff scar tissue that builds up after injury.
- Who was studied
- Mice with experimental cardiomyopathy, an animal disease model ahead of human trials.
- Good to know
- Relaxin-family peptides can nudge blood pressure down, so go easy if you already run low. Skip it during pregnancy; relaxin is a pregnancy hormone, and that's not one to freelance with.
