Cheaper isn't always better — but at price-parity, mechanism choice matters more than brand loyalty. Receptor saturation After a long LL-37 cycle, response can plateau due to receptor downregulation. Switching to a different mechanism (alt receptor target or pathway) refreshes signal. Availability Vendor stockouts force temporary substitution. Knowing which alternatives share therapeutic goals lets you maintain a protocol through supply gaps.
