TB-500 Peptide (Thymosin Beta-4) – Frequently Asked Questions

What is TB-500 peptide?

TB-500 is a synthetic research peptide modeled on Thymosin Beta-4, a 43-amino-acid peptide that has been examined extensively in published research literature for its role in actin-binding and cytoskeletal dynamics research. Genryse supplies TB-500 as a research peptide for in-vitro laboratory research only. It is not intended for human consumption, athletic use, or veterinary use.

Is TB-500 the same as Thymosin Beta-4?

TB-500 and Thymosin Beta-4 (Tβ4) refer to the same 43-amino-acid synthetic research peptide that Genryse supplies. The names are used interchangeably in research literature. Some competitors supply only the shorter LKKTETQ fragment under the TB-500 name – Genryse supplies the full-length 43-amino-acid Thymosin Beta-4 sequence, verified by mass spectrometry on every lot.

What sizes of TB-500 does Genryse offer?

Genryse TB-500 is supplied in two lyophilized vial sizes: 5mg and 10mg. Each size ships with the same 99%+ purity verification and a lot-specific COA.

How does TB-500 differ from BPC-157 in research?

Both TB-500 and BPC-157 have been examined in tissue-repair and connective-tissue research literature, but they are different research peptides. TB-500 (Thymosin Beta-4) is a 43-amino-acid peptide examined in actin-dynamics and cytoskeletal research. BPC-157 is a 15-amino-acid peptide examined in body-protection-compound research. Genryse also supplies a BPC-157 / TB-500 Blend for researchers studying both compounds together.

How should TB-500 research peptide be stored?

Lyophilized TB-500 should be stored at -20°C until reconstitution, then at 2–8°C following reconstitution. Maintain aseptic handling practices and refer to the lot-specific COA and the Genryse peptide storage guide for full handling protocols.

Is TB-500 supplied for athletic use or human application?

No. TB-500 supplied by Genryse is a research peptide intended exclusively for in-vitro laboratory research and analytical study. It is not intended for athletic use, human consumption, dietary supplementation, equine veterinary application, or any clinical use.

Does TB-500 ship with a COA?

Yes. Every Genryse TB-500 research peptide ships with a lot-specific Certificate of Analysis verifying 99%+ purity and molecular identity. Sample COAs are available for review prior to purchase.
