Why We Started Peptide Pal

Peptide Pal was founded after recognising a clear gap in the UK research supply market. Too many suppliers were operating with inconsistent testing practices, incomplete documentation, or in regulatory grey areas that left researchers unable to fully verify the compounds they were working with.

For scientists conducting serious research, this matters enormously. Unreliable compounds produce unreliable data. We set out to build a supplier whose quality claims could be independently verified at every step — one whose documentation was complete, whose supply chain was transparent, and whose research-only mandate was genuine rather than a formality.

Today, Peptide Pal supplies a growing catalogue of research-grade peptide compounds to scientists, institutions, and research laboratories across the UK and internationally. Every compound in our range is independently tested by accredited third-party analytical laboratories, and every batch is independently COA tested before it leaves our facility.

We are not a general health supplement company that also sells research chemicals. We are a dedicated research supply company — and that focus shapes every decision we make, from the compounds we stock to the documentation we provide.

Our Differentiators

What Sets Us Apart

In a market where quality claims are easy to make and difficult to verify, we hold ourselves to a higher standard.

01

Independently Verified — Not Self-Certified

Every batch we sell is tested by accredited, independent third-party analytical laboratories — not by us. HPLC and mass spectrometry results come from external labs with no commercial interest in the outcome. When we say 99%+ purity, that figure was confirmed by someone other than us.

02

COA Tested — Every Batch, Every Compound

Every batch is independently COA tested as standard — covering purity percentage, molecular weight, batch number, test methodology, and absence of contaminants. Full transparency, no exceptions.

03

Research-Only — No Grey Areas

We supply research compounds and nothing else. We do not market our products for human use, we do not provide dosing guidance, and we do not operate in the grey space between research supply and consumer retail. Our mandate is clear, and we enforce it at every point of sale.

From Source to Dispatch

Our Quality Process

Every compound passes through a five-stage quality process before it reaches a researcher's laboratory.

1

Pharmaceutical-Grade Synthesis

We work exclusively with synthesis facilities that operate to pharmaceutical-grade standards, using validated solid-phase peptide synthesis (SPPS) methods. Raw materials are sourced from accredited suppliers, and synthesis is carried out under controlled, documented conditions.

2

Independent Third-Party Testing

Each batch is submitted to an accredited, independent analytical laboratory for HPLC purity analysis and mass spectrometry confirmation of molecular identity. We do not release any batch for sale until independent test results confirm it meets our minimum 99% purity threshold.

3

Independent COA Testing

Every batch undergoes independent COA testing incorporating: purity percentage by HPLC, molecular weight by mass spectrometry, batch identification number, test date, and confirmation of the absence of specified contaminants.

4

Internal Quality Review & Approval

Before any batch is released for sale, it undergoes an internal quality review. Documentation is checked for completeness, test results are cross-referenced against product specifications, and labelling is verified to comply with our research-use-only supply requirements.

5

Secure Packaging & Dispatch

Approved compounds are supplied as lyophilised powder in sealed, sterile vials with tamper-evident closures. Each shipment is packaged in temperature-appropriate materials and includes research-use-only labelling. Orders are dispatched within 1–2 business days via tracked courier.

Technical Standards

Our Testing Methods in Detail

We use the gold standard analytical techniques accepted by the global research community.

HPLC

High-Performance Liquid Chromatography

HPLC is the primary method used to determine compound purity. Our testing utilises reverse-phase HPLC, which separates and quantifies the constituent components of a compound by molecular polarity. The percentage of the target compound relative to all detected species is expressed as the purity figure reported in COA testing.

  • Reverse-phase separation methodology
  • UV-Vis detection at 220nm
  • Results expressed as percentage area
  • Minimum threshold: 99% purity
MS

Mass Spectrometry Confirmation

Mass spectrometry confirms molecular identity by measuring the mass-to-charge ratio of ionised molecules. This verifies compound identity and identifies any structural anomalies or unexpected mass species that may indicate synthesis errors or contamination.

  • ESI-MS (electrospray ionisation)
  • Confirms molecular weight to specification
  • Detects structural anomalies
  • Cross-referenced against reference databases
COA

COA Testing — What It Covers

Our independent COA testing is conducted by accredited laboratories and covers all information necessary to verify compound identity and purity.

  • Compound name, CAS number & molecular formula
  • Batch identification number & test date
  • HPLC purity percentage with chromatogram
  • Mass spectrometry molecular weight confirmation
  • Contaminant absence declaration
  • Storage conditions & shelf-life guidance
GMP

Synthesis & Handling Standards

All compounds are synthesised in facilities that operate to Good Manufacturing Practice (GMP)-equivalent standards. Lyophilisation (freeze-drying) ensures compound stability and extended shelf-life. Sealed vials maintain integrity during transit and storage.

  • Solid-phase peptide synthesis (SPPS)
  • Lyophilised powder in sealed sterile vials
  • Controlled-environment handling throughout
  • Temperature-appropriate shipping materials
Our Commitment

Supporting the Research Community

The quality of research depends on the quality of the tools and compounds researchers have access to. A purity discrepancy in a research compound does not just waste a scientist's time — it can corrupt experimental data, lead to false conclusions, and undermine months of work.

We take that responsibility seriously. Our role is not just to sell compounds — it is to be a dependable part of the research supply chain. That means consistent quality, transparent documentation, honest communication, and a supply policy that does not compromise the integrity of legitimate science.

We are committed to expanding our catalogue responsibly, maintaining our testing standards as we scale, and continuing to supply only to researchers who share our commitment to rigorous, ethical scientific investigation.

Consistency

Same rigorous process, every batch, every compound. Researchers can rely on independently verified compounds, every time.

Transparency

Full documentation publicly available. No hidden information, no vague quality claims, no omissions.

Integrity

Research-only supply with no exceptions. We enforce our mandate at every sale, without compromise.

Our Values

The Principles We Operate By

I
Integrity

We are transparent about our testing methods, our supply chain, and our research-only mandate. We do not make claims we cannot substantiate. No ambiguity, no misleading marketing.

P
Precision

Research depends on precise, consistent compounds. Every batch is verified to the same standard, so researchers can trust that what they received last month will match what they receive this month.

R
Responsibility

We supply exclusively to qualified researchers and institutions. Our research-only mandate is not a legal formality — it is central to how we operate. We take our role in the supply chain seriously.

S
Science First

We exist to support legitimate scientific research. Every decision — from which compounds we stock, to how we document batches, to who we supply — is made with the research community in mind.
