BPC-157- Summary
- Thymosin Beta-4 is an endogenous 43-amino acid peptide that is the primary intracellular actin sequestering peptide. It promotes tissue repair, reduces inflammation, regenerates hair follicles, and protects cardiac tissue. Closely related to TB-500 (the active fragment), it is used for systemic tissue recovery and anti-aging.
- BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in the stomach. It is one of the most extensively researched healing peptides, known for accelerating tissue repair, reducing inflammation, and protecting the gastrointestinal tract.
- Half-Life
- Not well characterized; likely similar to TB-500 (~1–2 hours)
- 4–6 hours
