Key Features
- Price: $35.00 per vial
- Form: Lyophilized powder
- Availability: In stock
- Public COA: Not displayed
- Stated purity: Not disclosed
- Vial size: Not disclosed
At $35.00, PeptideGod's TB-500 falls on the lower end of market pricing. Suppliers that publish COAs and provide HPLC data typically sell TB-500 for $40-$50 per vial. The price difference of $5-$15 reflects the absence of publicly available analytical documentation. PeptideGod also sells TB-500 as part of its BPC-157 + TB-500 blend at $59.95.
What's Inside
- Peptide: TB-500 (Thymosin Beta-4 fragment)
- Parent protein: Thymosin Beta-4, a 43-amino-acid protein
- Form: Lyophilized powder requiring reconstitution with bacteriostatic water
TB-500 is not the full Thymosin Beta-4 protein. It is a fragment containing the region believed to include the actin-binding domain, which has been the focus of preclinical studies. The product page does not include a COA. No HPLC data, endotoxin screening results, or mass spectrometry findings are listed.

How to Store and Handle
Keep the sealed vial at -20C for long-term storage. For short-term storage of a few weeks, 2-8C is acceptable. The lyophilized powder tolerates room temperature during transit. Refrigerate or freeze immediately upon receipt.
To reconstitute, draw bacteriostatic water into an insulin syringe and 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 each draw. Store the reconstituted solution at 2-8C and use within 28 days. Do not refreeze. For volume calculations, visit our reconstitution calculator. For handling best practices, see our peptide safety guide.

PeptideGod TB-500 is a lyophilized research vial priced at $35.00. The product ships from US inventory and is listed as in stock. The product page does not display a COA. Purity percentage, milligram amount, and endotoxin data are absent from the listing. Our editorial team reviewed the product details, compared pricing, and evaluated it across 4 scoring parameters.
Overview
TB-500 is a synthetic peptide fragment of Thymosin Beta-4. The full Thymosin Beta-4 protein contains 43 amino acids and is involved in cell migration, cytoskeletal organization, and tissue repair processes. Preclinical research has examined TB-500 for wound healing, cardiac repair, and anti-inflammatory activity in animal models. Human clinical data for TB-500 remains limited. All findings discussed on this page come from preclinical studies only.
PeptideGod presents TB-500 as a single-compound research vial in lyophilized form. The listing provides the product name and price but does not include details such as vial size in milligrams, purity, salt form, or analytical testing methodology. For a broader look at how PeptideGod's documentation compares to competitors, see our PeptideGod vs Real Peptides comparison.
Our Verdict
PeptideGod TB-500 scores 3.7 out of 5 from our editorial team, reviewed by Emily Kang. Sub-scores: Testing 3.0, Purity 3.0, Labeling 3.3, Value 4.5. The value score reflects a competitive price at $35.00. Testing and purity scores are low because the product page does not display a COA and purity is unstated.
The $35.00 price is competitive. The product ships from US stock and is consistently available. The weaknesses are consistent with PeptideGod's catalog as a whole: no certificate of analysis, no purity claims, and no endotoxin data. The milligram amount per vial is not stated, which prevents price-per-milligram comparison with other vendors. Researchers who require confirmed analytical data should evaluate suppliers that share lot-specific reports. For the full list of vendors we have evaluated, see our peptide brands directory. PeptideGod also sells BPC-157 at $34.95 and a BPC-157 + TB-500 blend at $59.95.

FAQ
Is TB-500 the same as Thymosin Beta-4?
No. TB-500 is a synthetic fragment of the full Thymosin Beta-4 protein. It contains the active region associated with actin binding and cell migration studied in preclinical research. While the two terms are sometimes used interchangeably in the market, they are not identical compounds.
What purity is PeptideGod TB-500?
No purity percentage, HPLC testing method, or laboratory name appears on the product page. Vendors who provide COAs for TB-500 typically report purity at 98% or higher.
How does PeptideGod TB-500 compare on price?
At $35.00 per vial, it is among the lower-priced TB-500 products. Vendors with published COAs sell TB-500 for $40-$50. The $5-$15 gap corresponds to the absence of public analytical documentation. Because the milligram amount is not stated, a true cost-per-milligram comparison cannot be performed.
Can TB-500 be combined with BPC-157 in research?
These two peptides are frequently studied together in preclinical protocols. PeptideGod sells them separately (BPC-157 at $34.95, TB-500 at $35.00) and as a pre-mixed blend at $59.95. Separate vials allow independent concentration control. The blend does not. See our BPC-157 + TB-500 stack page for more details.
