Research peptides are short chains of amino acids — typically 2 to 50 residues — synthesized for laboratory investigation of specific receptor pathways, signaling cascades, and physiological systems. Unlike pharmaceutical drugs, research-grade peptides are supplied exclusively for controlled scientific study, not for human consumption.
Each peptide class targets a distinct biological system: incretin hormone receptors (GLP-1 peptides), growth hormone secretagogue receptors (GHRPs and GHRH analogs), tissue repair pathways (healing peptides), or central nervous system signaling (cognitive peptides). Selecting the right compound depends on which receptor system and downstream signaling pathway your experiment is designed to isolate.
OmegaCore Research supplies HPLC-verified, third-party tested peptides with full Certificates of Analysis — ensuring the compound purity and batch consistency essential for reproducible scientific results.
GLP-1 Peptides
Incretin hormone analogs — Semaglutide, Tirzepatide — studied for glucose metabolism and appetite signaling.
Growth Hormone Peptides
GHRPs and GHRH analogs — Ipamorelin, CJC-1295, GHRP-6 — studied for GH axis stimulation and recovery.
Healing & Recovery Peptides
Tissue repair compounds — BPC-157, TB-500, GHK-Cu — studied for angiogenesis and cellular protection.
Cognitive Peptides
CNS-active compounds — Semax, Selank — studied for neuroprotection and neurotrophic signaling.
