Q&A
Is TB500 (Thymosin Beta-4 Acetate) third-party tested?
Yes. Every batch of TB500 from globalpeptidesofficial.com goes to Janoshik Analytical before it ships. So you get the actual lab report not just a manufacturer certificate.
The COA shows 99.36% purity by HPLC. That result is tied to a specific batch number. You can verify it yourself on the Janoshik website.
What is TB500 (Thymosin Beta-4 Acetate) made of?
Also TB500 is a synthetic version of a naturally occurring peptide called Thymosin Beta-4. It is a chain of 43 amino acids. The acetate salt form is used for stability in lyophilized (freeze-dried) powder.
Also, the sequence starts with Ac-LKKTETQ. This acetylated N-terminus is what makes it TB-4 Acetate specifically. It is not the same as raw Thymosin Beta-4 fragments.
How should TB500 research peptide be stored?
Firstly, keep sealed vials at −20°C and away from light. The lyophilized powder is stable for 24+ months under those conditions.
Next, once you reconstitute it with sterile or bacteriostatic water, store the solution at 2–8°C. Use it within 30 days. However, do not freeze a reconstituted solution that degrades the peptide.
What purity does TB500 from globalpeptidesofficial.com have?
The current batch tests at 99.36% purity by HPLC. That result comes from Janoshik, an independent Czech lab. Therefore, it is not self-reported data.
Finally, the COA is posted on the product page at globalpeptidesofficial.com so researchers can download it before ordering. No request needed.
Is TB500 (Thymosin Beta-4 Acetate) the same as BPC-157?
No. They are two different peptides. TB500 is a 43-amino acid chain derived from Thymosin Beta-4. BPC-157 is a 15-amino acid pentadecapeptide from gastric juice protein BPC.
But some researchers use both in the same study because their mechanisms differ. So comparing them is like comparing two separate research compounds — they are not interchangeable.
TB500 (Thymosin Beta-4 Acetate) is a synthetic peptide designed to mirror the effects of Thymosin Beta-4 (Tβ4), a naturally occurring protein found in nearly all human and animal cells. It is popular in athletic and biohacking communities for its potential to accelerate injury recovery, reduce inflammation, and promote tissue regeneration
