Devilishly radical NETwork in COVID-19: Oxidative stress, neutrophil extracellular traps (NETs), and T cell suppression
This effect can be antagonized by kinase-protein kinase B (AKT) inhibitors and phosphatidylinositol 3-kinase (PI3K) inhibitors (Chen et al., 2012)

Note: TB-500 is far less studied than full-length Thymosin -4, and the following effects are primarily supported for the parent compound: Actin Binding: Sequesters G-actin monomers, regulating cytoskeletal dynamics essential for cell movement (PMID: 22074294 - Thymosin -4) Cell Migration: Enables endothelial cells, keratinocytes, and other repair cells to migrate to injury sites (PMID: 22074294 - Thymosin -4) Anti-inflammatory: Reduces inflammatory cytokines and promotes resolution of inflammation (PMID: 30116499 - Thymosin -4) Matrix Metalloproteinase Regulation: Modulates tissue remodeling enzymes for proper scar formation (PMID: 16607611 - Thymosin -4) Stem Cell Recruitment: May enhance mobilization of stem cells to damaged areas (PMID: 22074294 - Thymosin -4) Complementary Action: BPC-157 establishes the blood supply (angiogenesis) needed for healing, while TB-500 facilitates the cellular migration and tissue remodeling that follows

Nearly all positive human studies have been small, uncontrolled, and authored by people selling the peptide
The injection can be performed by a physician, or by a nurse or assistant under the [direct supervision] of the physician.
