TB-500 10mg – Research Peptide in Lyophilized Powder Form

Product Overview

TB-500 10mg is a peptide research product supplied in lyophilized powder form for laboratory research applications. It comes in a 7 mL vial and is supplied as a dry powder that has not been reconstituted. The product is intended for controlled laboratory research and analytical investigation, not for human consumption, veterinary use or self-administration.

TB-500 is a name commonly used in research-related commercial contexts for products associated with thymosin beta-4 (TB4). These terms are related in the peptide research literature, but they should not automatically be treated as proof that every product marketed under the TB-500 name is identical to full-length thymosin beta-4. Researchers should establish the identity, composition and specifications of a material using appropriate documentation and analytical methods.

For laboratories evaluating peptide materials, clear product specifications and batch-level analytical information are important parts of procurement. Global Peptides Lab presents the available test information for this product to help research purchasers review the reported quality indicators before deciding whether the material meets their laboratory’s requirements.

Understanding TB-500 and TB4

Thymosin beta-4 is a naturally occurring peptide that has been investigated in scientific research involving cellular processes, including actin regulation and cell migration. These biological research topics have attracted interest in studies of tissue biology and repair mechanisms.

The name TB-500 is also used commercially for certain synthetic peptide materials associated with thymosin beta-4. However, commercial naming alone does not establish a material’s precise sequence, molecular identity or equivalence to the naturally occurring peptide. Product identity should be assessed using appropriate documentation and analytical verification rather than the product name alone.

Research findings about thymosin beta-4 or related compounds should not be interpreted as evidence that a commercial TB-500 product is approved, effective or safe for treating a medical condition. This listing makes no therapeutic or performance-enhancement claims.

Reported Purity and Weight Results

The supplied batch information reports a purity result of 99.016% and a measured weight of 11.50 mg. Purity testing can help characterize the proportion of the target material relative to detected impurities under the method used. However, the meaning of a reported purity percentage depends on the analytical technique, calculation method and reference standard.

The reported weight is a separate measurement from purity. It should not be interpreted as proof of the exact quantity of active peptide without supporting documentation that establishes what was weighed and how the measurement was performed.

For research procurement, reviewing the original analytical report is advisable. Researchers may need additional identity testing, such as suitable mass spectrometry or chromatographic analysis, depending on the experimental requirements. No single result should be assumed to establish every aspect of product quality.

TFA Testing and Endotoxin Screening

Trifluoroacetic acid (TFA) can be relevant to peptide manufacturing and purification processes. The supplied test information records the TFA result as “Not Detected.” This wording means that the reported test did not detect TFA under its particular testing conditions; it does not necessarily establish absolute absence at every possible concentration.

The batch information also reports a passing result for endotoxins, commonly assessed through testing for bacterial lipopolysaccharides (LPS). Endotoxin screening is one element of evaluating a material for laboratory suitability. Its interpretation depends on the test method, detection limit and applicable acceptance criteria.

A reported pass should not be taken as proof of universal suitability for every experiment or application. Laboratories should establish their own acceptance criteria based on the intended analytical or experimental work.

Sterility Results and Research Quality

The supplied batch record lists the sterility result as “Pass.” Sterility testing can be relevant when evaluating materials for research protocols that require documented microbial controls. Nevertheless, a passing result applies within the limits of the test performed and the sample examined.

Sterility, purity, identity and endotoxin content are different quality attributes. A product may have a reported result for one attribute without that result proving the others. Proper assessment therefore involves reviewing the complete documentation and considering whether the analytical methods are appropriate for the intended laboratory work.

Global Peptides Lab recommends that research purchasers retain batch records and consult the applicable certificate of analysis before incorporating any research material into a study.

Batch Test Results

The available batch information for this research peptide is associated with batch number TB04260910I, with a reported test date of May 13, 2026.

The supplied results are summarized below:

• Purity: 99.016% reported.
• Weight: 11.50 mg reported.
• TFA: Not detected in the reported test.
• Endotoxins (LPS): Pass, as reported.
• Sterility: Pass, as reported.

These are reported batch-specific results, not an independent certification by Global Peptides Lab or a claim that the results have been independently verified. Consult the original test documentation for laboratory identification, test methods, acceptance limits and other relevant details.

Storage and Handling Considerations

Lyophilized peptide materials can be sensitive to environmental conditions. Storage requirements depend on the material’s verified specifications, packaging, stability data and manufacturer instructions. Research facilities should follow the documented storage and handling conditions applicable to the specific batch.

Keep research materials appropriately labeled and secured, and follow laboratory procedures for handling, recordkeeping and disposal. Do not assume that a particular storage temperature, shelf life or post-reconstitution stability period applies unless it is supported by the relevant product documentation.

This product is supplied as a non-reconstituted powder. No reconstitution instructions or human-use dosing guidance are provided because the product is offered for laboratory research purposes only.

Frequently Asked Questions

What form does this product come in?

It is supplied as a lyophilized powder in a 7 mL (6R) vial. The product is not reconstituted.

What purity is reported for this batch?

The supplied batch information reports a purity of 99.016%. The original analytical report should be consulted to understand the test method and the meaning of the result.

What does the TFA result mean?

The reported result is “Not Detected.” Interpretation depends on the analytical method and its detection limit; this wording does not necessarily mean that absolutely no TFA is present.

Does a passing sterility result guarantee suitability for every laboratory application?

No. A reported sterility result must be interpreted within the scope of the test performed. Researchers should assess the complete documentation and their own laboratory requirements.

Is this product intended for human use?

No. This product description is for laboratory research procurement only. It does not recommend human or veterinary use, self-administration, or use to diagnose, treat, cure or prevent any disease.
