PeptideGod TB-500 Overview

TB-500 is a synthetic peptide fragment of Thymosin Beta-4. The full protein contains 43 amino acids and participates in cell migration, cytoskeletal organization, and tissue repair processes. Preclinical studies have examined TB-500 for wound healing, cardiac repair, and anti-inflammatory activity in animal models. Human clinical data remains limited.

PeptideGod offers TB-500 as a single-peptide research vial. The listing states the product name, price, and stock status. It does not provide vial size in milligrams, purity data, salt form, or analytical methodology. TB-500 is the second most popular peptide in PeptideGod's catalog after BPC-157. The vendor also sells these 2 peptides as a pre-blended vial at $59.95.

Key Features

• Price: $35.00 per vial
• Form: Lyophilized powder
• Availability: In stock, US warehouse
• Public COA: None
• Stated purity: Not disclosed
• Vial size: Not disclosed

At $35.00, this vial is on the lower end of TB-500 pricing. Suppliers with published COAs and HPLC data typically sell TB-500 for $40.00-$50.00 per vial. The $5.00-$15.00 price difference reflects the absence of public analytical documentation.

What's Inside

• Peptide: TB-500 (Thymosin Beta-4 fragment)
• Parent protein: Thymosin Beta-4, 43 amino acid residues
• Active region: Actin-binding domain involved in cell migration
• Form: Lyophilized powder requiring reconstitution with bacteriostatic water

TB-500 is not the full Thymosin Beta-4 protein. It is the synthetic fragment containing the active region responsible for actin binding. The product page does not include a COA. HPLC purity data, endotoxin screening, and mass spectrometry results are not listed. The milligram content per vial is not stated.

How to Store and Handle

Store the sealed vial at -20C for long-term preservation. Short-term storage at 2-8C is acceptable for periods up to a few weeks. The lyophilized powder tolerates room temperature during shipping. Refrigerate or freeze immediately upon receipt.

To reconstitute, draw bacteriostatic water into an insulin syringe. Inject slowly along the inner wall of the vial. Do not shake or vortex. Allow the powder to dissolve passively. Swab the rubber stopper with an alcohol pad before every draw. Store the reconstituted solution at 2-8C. Use within 28 days. Do not refreeze.

Our Verdict

PeptideGod TB-500 scores 3.7 out of 5. Sub-scores: Testing 3.0, Purity 3.0, Labeling 3.5, Value 4.0. The value score reflects the competitive $35.00 price point. Testing and purity scores are the lowest because the listing provides no COA and no purity data.

The $35.00 price is accessible. US stock and consistent availability are genuine strengths. The weaknesses mirror all PeptideGod products: no Certificate of Analysis, no purity claims, no endotoxin data, and no stated vial size in milligrams. Researchers who need verified composition should consider vendors that publish lot-specific reports. PeptideGod also sells BPC-157 at $34.95 and a BPC-157 + TB-500 blend at $59.95.
