B12 injections alone dont address any of those levers directly
Vitamin B12 Supplements Depending upon the reason for the vitamin B12 deficiency, It may be treated through oral supplements or injections
they are managing hundreds

it has the strongest evidence for GI repair including ulcers, IBD models, and gut barrier integrity Tendon-to-bone healing multiple studies show accelerated tendon repair and reattachment Neuroprotection interaction with dopaminergic and serotonergic systems Oral administration BPC-157 survives stomach acid, making it the only healing peptide with oral bioavailability Where TB-500 Has Stronger Evidence Cardiac tissue repair parent molecule (TB-4) shown to activate epicardial progenitor cells in Nature publications Muscle regeneration superior satellite cell activation and muscle fiber repair Wound healing extensive dermal wound closure data Anti-fibrotic effects reduces excessive scar tissue formation across multiple tissue types Corneal healing significant clinical research in eye injury repair Where Both Are Strong Tendon & ligament repair both show significant benefit through different pathways Anti-inflammatory effects both reduce pro-inflammatory cytokines Angiogenesis both promote new blood vessel formation (different pathways) Dosing Comparison For research and educational discussion only
