BPC-157 Pentadecapeptide
Database Architecture & Analytical Governance
The Peptides UK Registry operates as a non-commercial reference standard for academic research teams, biotechnology laboratories, and clinical analytical chemists.
Primary Chemical Identity & IUPAC Indexing
Every compound record is anchored to primary reference databases including PubChem, UniProt, and the CAS Registry. We catalog exact amino acid sequences, monoisotopic molecular weights, SMILES notation, and empirical formulas to eliminate mislabeled commercial preparations.
Empirical Analytical Standards (HPLC & MS)
Lyophilized peptide batches require dual-assay analytical verification: Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) demonstrating ≥98.0% peak purity, and Electrospray Ionization Mass Spectrometry (ESI-MS) confirming exact isotopic mass without truncation artifacts.
UK Statutory Compliance & Laboratory Ethics
Our registry maps regulatory standing under the Human Medicines Regulations 2012 (SI 2012/1916), Misuse of Drugs Act 1971, and CAP Code 12.11. All compounds are cataloged exclusively for in vitro laboratory research, prohibiting consumer medical and self-administration claims.
Commercial Reagent Vendors & Batch Availability
Directly cross-reference UK suppliers providing lot-specific HPLC certificates, cold-chain Royal Mail Tracked 24 dispatch, and analytical-grade solvents: PharmaGrade, Direct Peptides, Direct Sarms, Peptide Works, and PharmaLab Global.

The 4 Quality Benchmarks for UK Laboratories
Essential analytical criteria required to verify synthetic peptide reagents prior to laboratory receipt, dilution, or in vitro cell culture.
Lot-Specific RP-HPLC Assays
Analytical laboratories require batch-specific Certificates of Analysis where the lot number printed on the vial label directly matches the raw chromatographic data file. The trace must show a single sharp peak under standard C18 reverse-phase elution without broad shoulder impurities.
ESI-MS Molecular Identity
While HPLC confirms purity percentage, Electrospray Ionization Mass Spectrometry (ESI-MS) confirms exact molecular mass. The spectrum must confirm the protonated [M+H]+ and multivalent [M+2H]2+ ions matching theoretical monoisotopic mass to rule out amino acid deletion sequences.
Endotoxin & Pyrogen Control
For cell culture and in vitro tissue viability experiments, bacterial endotoxin contamination induces inflammatory cytokine cascades (TNF-α, IL-6) that invalidate experimental assays. Certified reagents must pass Limulus Amebocyte Lysate (LAL) testing.
Cold-Chain Lyophilization Integrity
Properly lyophilized cakes under high-vacuum nitrogen purge remain stable at room temperature during domestic Royal Mail Tracked 24 transit. However, moisture content must remain below 3.0% to prevent spontaneous peptide hydrolysis and chain fragmentation.

Curated Biochemical & Regulatory FAQs
Essential legal, analytical, and handling questions answered with statutory citations to UK statutes, pharmacopeial monographs, and ISO 17025 verification standards.
Yes. In the United Kingdom, non-scheduled synthetic research peptides (such as BPC-157, TB-500, Semax, GHK-Cu, and Ipamorelin) are entirely lawful to purchase, import, and possess for legitimate laboratory research and in vitro scientific experimentation. They are not controlled substances under the Misuse of Drugs Act 1971. However, under Regulation 46 of the Human Medicines Regulations 2012 (SI 2012/1916), it is a criminal offence to market, sell, or supply these unlicensed substances for human therapeutic administration or self-injection without a marketing authorisation granted by the MHRA.
Chemical Repository Governance & Standards
The Peptides UK Registry is dedicated to providing open, rigorous, and legally compliant biochemical reference data for British researchers, preventing the proliferation of unsubstantiated clinical claims.
OECD GLP Compliance
Every monograph entry adheres to the OECD Principles of Good Laboratory Practice (ENV/MC/CHEM(98)17). Reconstitution volumes and physicochemical constants are verified against British Pharmacopoeia monographs.
Statutory UK REACH Verification
All chemical compounds are indexed in accordance with the UK REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations under the Health and Safety Executive (HSE).
Independent Audit Integrity
The Peptides UK Registry is editorially independent and does not manufacture, bottle, or dispense synthetic chemicals. Vendor evaluations are based on verified ISO/IEC 17025 laboratory test certificates.
Statutory Classification of Synthetic Peptides in Britain
In Great Britain and Northern Ireland, synthetic peptides that lack Marketing Authorisation (MA) are regulated as unlicensed chemicals for laboratory research. Under the Human Medicines Regulations 2012, advertising, distributing, or selling these substances for human therapeutic use or ingestion without a marketing licence constitutes an offence.
Strictly prohibits sale for administration to humans without MHRA license.
Research peptides listed here are non-controlled Schedule substances for legitimate labs.
