Exogenous nitric oxide mediates alleviation of mercury toxicity by promoting auxin transport in roots or preventing oxidative stress in leaves of rice seedlings

Success depends on: Molecular size: Smaller peptides ( 3000 Da): TB-500 (4963 Da) - too large Growth hormone (22,000 Da) - way too large IGF-1 (7649 Da) - too large These require injection Most healing peptides: BPC-157 : Questionable nasal (injection or oral better) TB-500: Definitely injection only Most tissue repair peptides designed for injection Growth hormone secretagogues: Ipamorelin : Injection only CJC-1295 : Injection only GH peptides not designed for nasal Bioavailability too low nasally Weight loss peptides: Semaglutide : Injection only (or oral tablet form exists) Tirzepatide : Injection only These require subcutaneous delivery Rule of thumb: If the peptide is commonly injected by everyone probably needs injection If nasal spray versions are popular nasal likely works When in doubt injection more reliable How to properly use nasal spray peptides Technique makes or breaks results

Actin Sequestration & Cell Migration (TB-500): Utilizes the conserved LKKTET amino acid motif (residues 1723) to bind G-actin and dynamically control cytoskeletal architecture, enabling rapid keratinocyte and stem cell locomotion to sites of injury
Glutathione levels decrease with age, resulting in age spots, dull complexion, and wrinkles
18 A hallmark of MDR is the dysregulation of intracellular drug availability, primarily through impaired drug uptake and enhanced drug efflux, involving the SLC and ABC transporter families
