How research peptides are made and tested

A typical research-peptide workflow runs from synthesis to lyophilization. The lot CoA reports the two analytical steps: HPLC-UV purity and LC-MS identity.

  1. Synthesis

    Peptides of this kind are usually made by solid-phase synthesis, adding one residue at a time to a stated sequence.

  2. Purification

    The main product is typically isolated from synthesis by-products before assay.

  3. HPLC purity

    The lot CoA reports reversed-phase HPLC-UV purity as the integrated main-peak area.

  4. Mass-spec identity

    The lot CoA reports LC-MS identity by comparing observed mass with the expected mass.

  5. Lyophilization

    Research peptides are commonly dried under vacuum from a frozen sample and sealed as powder in glass vials.

  6. Sealed-vial dispatch

    The lot CoA is published on the batch documentation page. Move sealed vials to refrigerated or frozen storage on receipt.

Wolverine Blend FAQ

More questions are answered on the FAQ page.

What is Wolverine Blend?

Wolverine Blend is a common name for a lyophilized research vial labeled to contain BPC-157 10 mg and TB-500 10 mg (20 mg total). It is supplied for in vitro laboratory research only.

Is Wolverine Blend the same as the Wolverine stack?

Yes. Wolverine Blend, the Wolverine stack and the Wolverine peptide are three informal names for the same lyophilized BPC-157 + TB-500 research blend. The Wolverine stack page lists where the name is used.

What purity did lot White Cap test at?

Freedom Diagnostics Testing reported 99.59% purity by HPLC-UV for lot White Cap (accession 2608120749) on 2026-08-17, with identity confirmed by LC-MS.

Why does the CoA list Thymosin Beta-4 instead of TB-500?

The certificate reports the second peptide by its parent-protein name, Thymosin Beta-4 (UniProt P62328). It measured 9.78 mg of it in the tested vial, against a 10 mg label.

Why is the measured BPC-157 content higher than the label?

The label states 10 mg per vial. The lab measured 11.74 mg BPC-157 in the tested sample from lot White Cap.

How should it be stored?

Sealed vial: refrigerate at approximately 2–8 °C short-term; freeze at −20 °C or colder for long-term storage, protected from light. Full lab guidance on the storage and handling page.

What does the certificate of analysis cover?

Identity (LC-MS) and purity (HPLC-UV) for a specific lot, with the CoA accession and test date. See how to read a peptide CoA for the document layout.

Is Wolverine Blend for human or veterinary use?

No. Wolverine Blend is supplied as a laboratory research material. It is not a drug, dietary supplement or cosmetic, and it is not intended for human or veterinary use, or for diagnostic or therapeutic purposes.
