Purity You Can Verify
Every batch undergoes High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis before release. Independent third-party testing confirms purity exceeds 99% for each batch — not as a target, but as a minimum standard. The batch-specific Certificate of Analysis is published on our COA page, where you can match your vial's batch number to its results.

BPC-157 / TB-500 Blend (5mg + 5mg) | Co-lyophilised Research Peptide Blend
Composition: BPC-157 5mg + TB-500 (Thymosin β-4) 5mg — 10mg total, co-lyophilised Purity: >99% HPLC per component Form: Lyophilised powder Storage: –20°C (lyophilised); 2–8°C (reconstituted) Batch: B7392 — Exp. 05/2029
What Is This Blend?
This product is a co-lyophilised research blend supplying BPC-157 (5mg) and TB-500 / Thymosin β-4 (5mg) in a single vial. Each component has been independently characterised in preclinical research, and this fixed-ratio blend is formulated for in-vitro and preclinical research use. The two peptides engage distinct molecular targets and have been studied in complementary research paradigms involving angiogenic signalling, actin dynamics, and cytoprotective pathways.
Component Research Profiles
BPC-157 (Body Protection Compound-157) BPC-157 is a 15-amino-acid pentadecapeptide (sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) derived from a partial sequence of body protection compound found in gastric juice. In preclinical research, BPC-157 has been investigated for its interactions with the nitric-oxide (NO) system and VEGFR2 (vascular endothelial growth factor receptor 2), with studies examining associated angiogenic signalling cascades in wound-healing and cytoprotective models. Research has also examined its effects on fibroblast activity, growth hormone receptor expression in tendon cell lines, and interactions with dopaminergic and serotonergic pathways in rodent models.
TB-500 (Thymosin β-4; Tβ4) TB-500 is the research name for synthetic Thymosin β-4, a 43-amino-acid N-acetylated peptide (CAS 77591-33-4) that functions as a principal G-actin-sequestering protein. Tβ4 binds G-actin (monomeric) via its LKKTET actin-binding motif, regulating the G-actin/F-actin equilibrium and thereby modulating actin polymerisation dynamics. In cell-based research, Tβ4 has been studied for its role in cytoskeletal organisation, directional cell migration, and endothelial cell behaviour in angiogenesis models. Research has also examined Tβ4 in cardiac progenitor cell models and extracellular matrix remodelling contexts.

Handling & Storage
Store the lyophilised blend at –20°C in the sealed vial until use. Once reconstituted in sterile bacteriostatic water or an appropriate aqueous buffer, aliquot and store at 2–8°C. Avoid repeated freeze-thaw cycles, which can degrade peptide integrity. All handling should comply with standard laboratory safety practices and applicable institutional guidelines.
Certificate of Analysis
This blend is independently tested and supplied with a Certificate of Analysis confirming purity by HPLC for each component. Batch B7392 — Exp. 05/2029. Available on request and via the Nexyra Lab COA verification portal.

Frequently Asked Questions
Is this product for research use only?
Yes. All Nexyra Lab products are strictly for in vitro research and laboratory use by qualified researchers. They are not approved for human or veterinary use by the FDA, EMA, or any other regulatory authority.
Is a Certificate of Analysis (COA) available?
Yes. A batch-specific COA from our independent third-party testing laboratory is published on our COA page — match your vial's batch number to access HPLC purity data, MS identity confirmation, batch number, and production date.
What does the Certificate of Analysis confirm?
The COA confirms: (1) purity ≥99% by HPLC; (2) molecular identity by mass spectrometry; (3) the batch number for traceability; and (4) the production date. It is produced by an independent laboratory, not by Nexyra Lab itself.
How should lyophilised peptides be stored?
Store lyophilised (freeze-dried) peptides at -20°C in a sealed, dry container away from light and moisture. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 4°C and use within 30 days for most peptides.
How do I reconstitute lyophilised peptides?
For most peptides, use sterile bacteriostatic water (BAC water) or sterile saline. Add the solvent slowly down the inside of the vial — do not inject directly onto the powder. Gently swirl until dissolved; do not shake. Use our Reconstitution Calculator at /peptide-calculator to determine the exact volume for your target concentration.
What are your dispatch and delivery times?
Orders placed before 3 pm on UK working days are dispatched same day. Standard UK delivery typically arrives within 1–3 working days. All orders are shipped in discreet, plain outer packaging with no reference to the contents.
What is your returns policy?
Due to the nature of research compounds and cold-chain requirements, we are unable to accept returns on opened products. If a product arrives damaged or incorrect, please contact our team within 48 hours of receipt and we will resolve the issue promptly.
What purity standard do your peptides meet?
All Nexyra Lab peptides are independently verified at ≥99% purity by HPLC before dispatch. Mass Spectrometry confirms molecular identity. This applies to every batch — the COA is batch-specific, not a generic certificate.
