TB-500 Certificate of Analysis

A widely studied structural peptide — and a common research pairing with BPC-157.

TB-500 is a synthetic 43-amino-acid fragment of Thymosin Beta-4 and one of the more extensively studied peptides in its category. It is frequently used as a reference compound in in-vitro and preclinical research. Supplied as a lyophilized powder for laboratory research use.

It is among the most widely referenced peptides in the published research literature and is commonly studied alongside BPC-157, which is why the two appear together in many research blends. Manufactured in the USA and independently tested to ≥99% purity.

Why this one matters: BPC-157, GHK-Cu, and TB-500 are three structurally distinct, widely studied peptides — which is why all three are commonly combined in research blends like GLOW and KLOW.

You ask, we answer

Everything you'd want to know about Aūra.

Verification, COAs, storage, handling — and what makes Aūra different. For research use only.

How are batches verified?
Independent third-party labs verify identity, purity, sterility, and endotoxins on every batch. Failed lots are rejected and never shipped.
Are COAs available?
Yes. Each shipment includes a batch-matched Certificate of Analysis tied to your specific lot number. Digital copies are also available through our COA library or by request.
What form will my peptides arrive in?
All Aūra peptides ship as lyophilized (freeze-dried) powder in sealed vials. Reconstitution instructions are provided with your shipment.
What purity specs do you follow?
≥99% purity confirmed via HPLC on qualifying batches. Mass verified via MS. All specs available on the batch-specific COA.
How should peptides be stored?
Store lyophilized vials at -20°C, protected from light. Once reconstituted, store at 2–8°C and use within the stability window noted on the COA.
Shelf life of unopened vials?
Unopened lyophilized vials are stable for up to 24 months when stored at recommended conditions. Exact shelf life is noted per batch on the COA.
What makes Aūra different?
Every batch is independently verified, lot-matched COAs ship with every order, and our verification standard rejects any batch that fails spec — no exceptions. Built for research labs that need reproducibility.
