Why oral, and how we make it work

Most peptides don't survive the stomach. Ours are built to.

Buffered
A sodium bicarbonate buffer protects the peptide from stomach acid.
Enteric-coated
The capsule opens in the small intestine, not the stomach.
Liposomal
Fat-soluble carriers for compounds that are not water-stable.

From the founder

I started Quiet Sciences because I wanted to know exactly what was in the capsule, and how much.

So we publish it. The dose, the delivery method, and the lab result for every lot we ship.
