BPC-157 vs TB-500
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
BPC-157
Body Protection Compound-157 is a synthetic peptide derived from a protein found in human gastric juice. It has shown remarkable healing properties in research studies.
Full details →TB-500
Thymosin Beta-4 (TB-500) is a naturally occurring peptide present in almost all human and animal cells. It plays a crucial role in tissue repair and regeneration.
Full details →Side-by-Side Comparison
| Aspect | BPC-157 | TB-500 |
|---|---|---|
| Dose Range | 250 mcg–500 mcg | 2 mg–2.5 mg |
| Frequency | 2x daily | Less than daily |
| Cycle Length | 4–6 weeks | 4–8 weeks |
| Route | subcutaneous | subcutaneous |
| Mechanism | BPC-157 works through multiple pathways including upregulation of growth factor expression, nitric oxide system modulation, and promotion of angiogenesis. It enhances tendon-to-bone healing and supports the formation of new blood vessels. | TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing. |
| Typical Dosage | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. | Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks. |
| Administration | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. |
| Side Effects | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. | May cause temporary fatigue, headache, or localized irritation at injection sites. |
