neuropeptide pharmacology

how ACTH fragments work on the brain without triggering cortisol

fragment pharmacology is the foundation

Semax derives its effects from the ACTH(4-10) fragment, which retains the cognitive and neuroprotective properties of full ACTH while completely lacking the hormonal activity that drives cortisol release. understanding this separation is the key to understanding the molecule.
