How is the product packaged?

All orders are shipped in plain, discreet packaging. Compounds are supplied as lyophilised powder in sealed glass vials unless stated otherwise. Your order arrives in unmarked packaging, protecting both your privacy and the integrity of the compounds during transit.

Can I return a product?

Due to the sterile nature of the products, no returns or exchanges are accepted after payment. Damaged or incorrect items must be reported within 48 hours of delivery with photographic evidence. We maintain strict chain-of-custody standards, and this no-return policy ensures every vial reaches the buyer uncompromised.

How should I store the compounds?

Lyophilised compounds should be stored at -20°C. Reconstituted solutions should be kept refrigerated at 2–8°C and protected from light. See each product page for specific storage instructions. Proper storage preserves the verified specifications of every compound under UK laboratory conditions.

Do you provide certificates of analysis?

Yes — a Certificate of Analysis is published for every product and every batch, independently tested in our UK QC laboratory. You can view and download all of them on our Lab Results page at hplcpeps.com/lab-results. No request needed. Every vial ships with a published COA confirming 99%+ purity, so researchers can order with full confidence in the testing data.

What payment methods do you accept?

We accept cryptocurrency (Bitcoin, Litecoin, Ethereum, and Solana) through our secure checkout. The checkout process is fast, secure, and does not require an account to complete your order.

What are peptides and what are they used for in research?

Peptides are short chains of amino acids (typically 2–50) linked by peptide bonds, sitting chemically between a single amino acid and a full protein. In laboratory research, peptides are studied for their signalling roles in metabolic pathways, tissue repair, growth hormone regulation, and melanocortin activity. Every compound in our catalogue is synthesised by solid-phase peptide synthesis and tested to 99%+ purity for reproducible research outcomes. All products are supplied strictly for professional laboratory research use only.

How do I reconstitute lyophilised peptides for laboratory use?

Lyophilised peptides are reconstituted by dissolving the powder in an appropriate solvent — typically bacteriostatic water for most compounds. Add the solvent to the vial gently and swirl until the powder is fully dissolved; avoid shaking, which can denature the peptide. The concentration depends on the volume of solvent added for your research protocol. Each product page includes specific reconstitution guidance, and our compounds dissolve cleanly thanks to their verified 99%+ purity.

What purity level should I look for when buying research peptides?

For reproducible laboratory research, always choose peptides verified at 99%+ HPLC purity. A peptide that is 90% pure introduces variability that undermines experimental results. HPLC Peps publishes HPLC data for every batch — all compounds are independently tested and confirmed by mass spectrometry, so researchers know the exact purity specification. Never accept a purity claim without a published Certificate of Analysis.

What is HPLC and why does it matter for peptide quality?

HPLC (High-Performance Liquid Chromatography) is an analytical technique that separates and quantifies the components of a peptide sample, measuring the proportion of the target compound versus impurities. HPLC verification gives researchers confidence that the vial contains what the label says it contains. HPLC Peps tests every batch by HPLC to confirm 99%+ purity, ensuring laboratories have the data they need for publishable research.

Are HPLC Peps peptides pharmaceutical grade?

Yes. Our peptides are synthesised from pharmaceutical-grade amino acids using solid-phase peptide synthesis and tested to 99%+ HPLC purity. While our compounds meet pharmaceutical-grade standards, they are sold strictly for laboratory research use only — not as medicines. The purity specification is verified by HPLC and mass spectrometry on every batch.

Can I buy peptides in bulk for my research laboratory?

Yes. We offer bulk pricing for laboratories, universities, and pharmaceutical companies that need larger quantities. Bulk orders qualify for automatic discounts at checkout. HPLC Peps accommodates purchase orders, proforma invoices, and institutional billing. Contact us to discuss bulk ordering for your organisation.

Do you sell to international researchers outside the UK?

Yes. HPLC Peps ships internationally, with shipping rates calculated at checkout based on destination. International customers are responsible for customs duties, taxes, and import compliance in their country. As a UK-based supplier, our published Certificates of Analysis and HPLC verification meet international research standards.

What is the difference between research peptides and peptides for human use?

Research peptides are supplied strictly for in-vitro and preclinical laboratory research — they are not medicines, not for diagnostic use, and not for administration to humans or animals. Peptides for human use require regulatory approval, clinical trials, and prescription oversight that fall outside the scope of a research supplier. HPLC Peps sells research compounds only, intended for professional laboratory use by verified institutions.

How fast is delivery when I order peptides from HPLC Peps?

Orders placed before noon on weekdays are typically dispatched same day, with Royal Mail Tracked 48 delivery (2–3 working days) to most UK addresses. Free shipping applies on orders over £100. Our UK dispatch facility ensures fast, tracked delivery to every postcode nationwide.

What is a Certificate of Analysis (COA) and why is it important?

A Certificate of Analysis (COA) is a laboratory document recording the test results for a specific batch of a compound, including HPLC purity and mass spectrometry identity confirmation. A COA proves that the peptide meets its labelled specifications. HPLC Peps publishes a COA for every batch on our Lab Results page — no request needed. This transparency allows researchers to verify quality before placing an order.

Do you offer discounts or promotional codes?

From time to time, HPLC Peps may issue promotional discount codes. These are single-use per customer and may be withdrawn or modified at any time. Bulk orders also receive automatic discounts at checkout. Our pricing is transparent with no hidden fees, and every compound carries the same published COA regardless of price point.

Which UK locations do you deliver to?

HPLC Peps delivers to every UK postcode — from London to Edinburgh, Manchester to Cardiff, and Belfast to Bristol. We serve universities, research laboratories, pharmaceutical companies, and biotech firms nationwide. Our town landing pages provide location-specific delivery information, with tracked shipping to every address. Free shipping applies on orders over £100 to all UK zones.

What research categories do your peptides cover?

HPLC Peps supplies peptides across four primary research categories: metabolic research (including GLP-1 agonists like semaglutide and tirzepatide), tissue repair research (including BPC-157 and TB-500), growth hormone research (including CJC-1295 and ipamorelin), and melanocortin research (including melanotan). Compounds are available in 10mg, 20mg, 30mg, and 100mg vials, all with published COAs for professional laboratory research.

Are HPLC Peps peptides suitable for cell-based assays and in-vitro research?

Yes. Our compounds are synthesised and tested for use in in-vitro and preclinical laboratory research, including cell-based assays, receptor binding studies, and signalling pathway research. A 99%+ purity specification reduces variability in your results — essential for reproducible cell-based work. Our published COAs confirm the quality that sensitive assays demand.

How do I verify that HPLC Peps is a legitimate peptide supplier?
