Side Effects B12 has an excellent safety profile because it is water-soluble (excess is excreted in urine)
TB-500 promotes angiogenesis (new blood vessel formation), which raises theoretical concerns for individuals with cancer history or risk factors
TB-500 contributes superior biomechanical outcomes including increased ultimate tensile strength, improved elastic modulus, and enhanced failure load in healed tissues, with the peptide accelerating muscle regeneration following traumatic injury through enhanced satellite cell activation, improved myofiber formation, and reduced inflammatory infiltration
While some users report enhanced local effects, the evidence for superiority over subcutaneous administration remains unclear, and complications including nerve irritation present greater concern
Roles of reactive oxygen species in inflammation and cancer
A peptide reconstituted in 0.9% saline lacks the preservative needed for multi-dose use, and the peptide will typically aggregate within 3-5 days of regular re-puncture
