The reading list

Research bibliography

The original titles are gathered below. Some describe people receiving treatment; others describe cells, animals or pieces of skin.

Starting points

For the fatty branch that opens this bulletin, start with Safety of Semaglutide. The weight and organ-outcome trials then ask what happened in defined groups of people.

The GHK skin-regeneration review introduces the copper chemistry. The KPV review follows the hormone fragment, and the BPC-157 clinical review surveys the gap between experimental repair findings and human trials. I'd read those before treating the molecules as a single subject. The full source list follows.
