- The origin difference is not philosophical — it has practical implications.
- SLU-PP-332 was rationally designed and synthesized to be an ERR pan-agonist. It does not exist in any organism. Receptor selectivity profiles, dose-response, and tissue distribution were engineered into the molecule.
- MOTS-c is a peptide your own mitochondria release under metabolic stress. Endogenous MOTS-c levels rise during exercise in human plasma (D'Souza et al., 2020, PMID 32182209). Administering exogenous MOTS-c is more accurately framed as supplementing a peptide the body already produces than as introducing a new pharmacological entity.
- That difference shows up in the safety conversation. MOTS-c has measured human exposure (endogenous + observational pharmacokinetic studies). SLU-PP-332 has zero human exposure data — no Phase 1, no IND, no formal pharmacokinetics in any human.
