Tissue repair, immune regulation, gut barrier and recovery. Companion articles to Regenerative Resilience.
Most repair protocols are built around the structural compounds people have heard of: BPC-157, TB-500, GHK-Cu. The immune system decides whether those compounds get to do anything. If the tissue is stuck in an inflammatory state, the repair signal lands on cells that can’t use it.
A peptide protocol is a sequence, not a shopping list. Tissue repair moves through distinct phases, and each compound has a phase where it helps most. Used in the wrong phase, a good compound can do little, and occasionally get in the way.
Every step of tissue repair needs energy. Cells get that energy from mitochondria, and mitochondrial output drops with age, chronic inflammation and metabolic disease. When it does, repair signals arrive at cells that don’t have the power to act on them. Most protocols never check for this.
The gut lining is a single layer of cells between what you eat and your bloodstream. When the seals between those cells loosen, bacterial fragments get through and switch on inflammation throughout the body, not just in the gut. That inflammation then slows repair everywhere else. BPC-157 and KPV are the two peptides most often discussed for protecting the lining.
