Overview of peptides in sports science research covering BPC-157 injury repair, GH axis body composition, IGF-1 muscle synthesis, TB-500 recovery, and MOTS-c exercise biology.
Learn the difference between in vitro and in vivo peptide research, the advantages and limitations of each, the translational hierarchy from cell culture to human studies, and ex vivo models.
Learn why most peptides are not orally bioavailable, the GI barriers they face, and strategies including cyclization, D-amino acids, SNAC, and nanoparticles that have achieved oral peptide delivery.
Learn what cyclic peptides are, how cyclization improves stability and selectivity, the types of cyclization chemistry used, and examples in research compounds including oxytocin and Melanotan II.
Trace the evolution of peptide research from insulin discovery through neuroendocrine pharmacology, GLP-1 rational design, and mitochondrial peptide biology to precision medicine.
Learn how receptor desensitization and downregulation affect research peptides including Hexarelin GH axis tachyphylaxis and how to design protocols that account for these phenomena.
Learn how research peptides including BPC-157, TB-500, GHK-Cu, and IGF-1 promote angiogenesis and why new blood vessel formation is central to tissue repair mechanisms.
Learn how amino acid hydrophilicity and hydrophobicity determine peptide solubility, how to use the GRAVY score, and practical solvent selection strategies for difficult peptides.
Learn how oxidative stress and ROS biology connects to research peptides including SS-31, GHK-Cu, Epithalon, and how to measure antioxidant effects in research protocols.
Learn how PEGylation extends peptide half-life through hydrodynamic radius, protease protection, and immunogenicity reduction, with PEG-MGF as the key research example.
