PeptideGod TB-500: Product Specs and Editorial Review

We reviewed the PeptideGod TB-500 vial, priced at $35.00 for 5mg. It ships as a lyophilized powder from Westminster, California. The product page follows the same pattern as other PeptideGod listings: a name, a price, and nothing else. No description, no purity data, no COA, no reviews. We evaluated it across 4 scoring criteria and compared pricing against vendors with published analytical reports.

PeptideGod TB-500 Overview

TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring protein involved in cell migration, cytoskeletal organization, and tissue repair. Preclinical research has examined it for wound healing, cardiac repair, and anti-inflammatory effects in animal models. Human clinical data is limited.

PeptideGod offers TB-500 in 2 sizes: 5mg at $35.00 and 10mg at $65.00. The per-milligram cost works out to $7.00 for the 5mg vial and $6.50 for the 10mg. Both are freeze-dried powders shipped from their California warehouse. The product is categorized under recovery and healing with tags for healing, performance, recovery, and repair. That is the full extent of what the listing provides. No product description, no stated purity percentage, no testing methodology, and no linked certificate of analysis. The product page carries zero customer reviews or ratings.

Key Features

At $35.00 for a 5mg vial, PeptideGod sits on the budget end of the TB-500 market. Vendors who include lot-specific COAs with HPLC data generally charge $40 to $55 for comparable sizes. The gap reflects the difference in documentation. Price alone does not tell you what is inside the vial.

What's Inside

• Peptide: TB-500 (Thymosin Beta-4 fragment)
• Protein of origin: Thymosin Beta-4, a 43-amino-acid protein involved in actin binding and cell migration
• Form: Lyophilized powder requiring reconstitution with bacteriostatic water

TB-500 is not the full Thymosin Beta-4 protein. It is a synthetic fragment containing the active region studied in preclinical research. The 2 terms get used interchangeably across vendor sites, but they are not the same molecule. We could not verify peptide identity or contamination levels from the PeptideGod listing because no COA, HPLC results, endotoxin screening, or mass spectrometry data are published.

How to Store and Handle

Keep the capped container in cold temperatures of -20 degrees Celsius for long-term storage. A regular refrigerator with a temperature range of 2-8 degrees Celsius will suffice for short periods of a few weeks. The lyophilized substance can safely be transported at ambient temperature but should be put inside the refrigerator as soon as it arrives.

As a first step, take the bacteriostatic water into an insulin syringe and slowly inject it along the edges of the container. Do not shake. Allow the substance to dissolve by itself. Clean the rubber stopper with an alcohol pad before using your syringe. Store the reconstituted solution in the range of 2-8 degrees Celsius and use it within 28 days.

Our Verdict

We scored PeptideGod TB-500 at 3.8 out of 5. Sub-scores: Testing 3.0, Purity 3.5, Labeling 3.5, Value 4.5. The value score carries the rating. Both the 5mg and 10mg options undercut most competitors, and shipping to 28 countries gives it broader reach than many US peptide vendors.

The flaws are similar to the ones present in the PeptideGod collection. There is no certificate of analysis, as well as purity claims, endotoxin information, and product description. Researchers who require reliable information regarding the composition and origin of the compound should seek suppliers which provide analytical reports for each lot manufactured by them. The options for the analytical providers are mentioned above in our best online sources resource. Finally, PeptideGod has also marketed standalone BPC-157 for $34.95 and BPC-157 + TB-500 blend for $59.95 that are based on combined protocols.
