I was shocked at how quickly I ran out of it. Used Cosrx peptide serum previously and it lasted months, without a noticable difference in effects from the P46. I was willing to try this more expensive option, but it ran out in about a month, using less than the recommended amount (I used 2-3 pumps twice daily). Disappointed.
