SPORT · TRAIL & ULTRA
Comrades, Two Oceans, Otter, Ultra-Trail Drakensberg: South Africa has one of the deepest ultra-running cultures in the world, and its runners read about recovery with the obsession the distance demands. Peptides come up in that reading, usually around muscle damage, gut problems on the road, and sleep.
This page is for the runner, coach or club who wants the literature rather than the lore. It covers exercise-induced muscle damage and repair models, the gut-barrier research that explains why ultras ruin stomachs, the sleep and circadian work relevant to multi-day events, and the mitochondrial literature. Compounds are supplied for laboratory research only; nothing here is for a runner to take.
Ultra-distance running produces three well-studied physiological insults: eccentric muscle damage, exercise-induced gut-barrier permeability, and sleep deprivation in multi-day formats. The peptide literature touches each. Muscle regeneration models in rodents involve BPC-157 and the thymosin β4 fragment; gut-barrier research involves BPC-157 again, as a gastric cytoprotective peptide, and KPV in colitis and barrier models; sleep research involves GHRH analogues, Epitalon and DSIP.
Mitochondrial work is the fourth strand. MOTS-c rises in plasma after exercise and is studied for AMPK and fatty-acid oxidation in mice; glutathione is measured as an oxidative-stress marker after prolonged running. Across all four strands the human evidence for the compounds is thin, and the models are mostly rodent. The literature is real; the application is not.
Research context only — what each compound has been studied for in published work, not what it does for anyone. Independently tested by Janoshik Analytical.
Isolated from gastric juice and studied for mucosal-barrier restoration as well as muscle and tendon repair. For an ultra reader it is the one compound that spans both the stomach and the quads literatures.

No. Everything we supply is for laboratory research. Several classes are prohibited in competition and nothing on this page is a recovery product.
Because exercise-induced gut permeability is one of the best-documented problems in ultra running, and BPC-157 and KPV are studied in gut-barrier models.
Almost none. The regeneration findings come from rodent crush and transection models.
