TB-500 (Thymosin Beta-4) is a complex peptide. Before buying, systematically check these 5 quality criteria:

1. Certificate of Analysis (CoA)

A serious supplier provides a batch-specific CoA. This document should include:

• HPLC chromatogram showing purity (≥98%)
• Mass spectrometry (MS) confirming molecular weight (4963.5 Da for TB-500)
• Endotoxin testing (for injectable forms)
• Batch number matching the vial label

Red flag: If the supplier can't provide a CoA or uses a generic document, avoid them.

2. Peptide Identification

TB-500 is a synthetic fragment of natural Thymosin Beta-4 (amino acids 17-23). Verify that the supplier specifies:

• Correct amino acid sequence
• Form (acetate or free salt)
• Molecular weight verified by MS

3. Storage Conditions

TB-500 is temperature sensitive. Verify that the supplier:

• Stores peptides at -20°C
• Ships with ice packs or dry ice
• Uses insulated packaging

4. Price Transparency

Be wary of abnormally low prices. Quality TB-500 10mg costs between $40 and $90. A price below $30 suggests:

• Lower purity
• Incorrect dosing
• Counterfeit product

5. Recovery Specialization

Prefer suppliers specialized in recovery peptides who understand researcher needs (TB-500, BPC-157, blends).
