In humans, TB4 is present in high concentrations in all tissue types except red blood cells, with highest levels occurring in platelets, white blood cells, plasma, and wound fluid.17 TB4 is an important actin-binding protein that helps actin perform various functions, such as muscular contraction and maintaining proper cell shape, movement, and division.18 19 These effects on cells are why some experts suggest supplemental TB4 can improve the repair and recovery of muscle and other soft tissues,20 21 promote wound healing,22 reduce inflammation, and more.23 Researchers also note that TB4 is critical for the repair and regeneration of eye, heart, skin, nerve, and brain tissue after injury.4 The derivative TB-500 is based on one of the active sites of TB4, specifically the peptide segment responsible for the compounds actin-binding and cell migration abilities.4 Since most of TB4s potential benefits are attributed to its actin-binding properties, it can be assumed that the same applies to TB-500

The absence of standardized human dosing makes the threshold for digestive side effects in humans undetermined

Pain and Irritation at Injection Site The most common reaction to B12 injections is pain, redness, swelling, or irritation, where the needle goes into your skin or muscle
All real-time PCRs were performed three times and all changes in gene expression were reported as multiples of increases relative to the control while GAPDH was used as an internal control and relative gene expression between the experimental groups were determined using MxPro software
BPC-157 also demonstrates anti-inflammatory properties, with research focusing on its ability to modulate inflammation and support recovery
