Research peptides catalogue

British Peptide Labs is a UK-registered supplier of research peptides, and this page is the complete catalogue: each compound we stock, with its vial sizes, prices and chemical identifiers. If you are looking for UK peptides for in-vitro laboratory work, browse the grid above, narrow it with the research-area and type filters, or read the whole range at a glance in the table.

Research areas group the catalogue largely by molecular class, so compounds that share a structural family sit together: Incretin & Amylin Analogues, Peptide Fragments, GHRH, GHS-R & IGF-1 Analogues, Melanocortin & Copper Peptides, Mitochondrial Compounds and Neuropeptides. Each research area page lists its compounds, sets out what they have in common structurally and links through to every product page, and the research areas overview brings all six together.

The Incretin & Amylin Analogues research area groups synthetic lipidated peptide analogues of roughly thirty to forty residues. Several carry α-aminoisobutyric acid (Aib) at selected positions, and each has a long-chain dicarboxylic acid attached to the backbone through a linker, which adds mass and lengthens retention on reversed-phase HPLC. GLP-3, tirzepatide, semaglutide and cagrilintide are listed here with CAS number, formula and molecular weight.

The Peptide Fragments research area collects linear synthetic peptides built from standard amino acids, with no cyclisation or lipidation, together with co-lyophilised blends of them. BPC-157 is a fifteen-residue chain with four proline residues, and TB-500 corresponds to the forty-three-residue thymosin β4.

The GHRH, GHS-R & IGF-1 Analogues research area groups analogues by the receptor class of the peptide each one is modelled on. It runs from ipamorelin, a pentapeptide with a C-terminal amide, through the forty-four-residue tesamorelin to IGF-1 LR3, a recombinant single chain of eighty-three residues.

The Melanocortin & Copper Peptides research area holds two families of short peptides: lactam-bridged cyclic heptapeptides of the melanocortin receptor family, and GHK-Cu, the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine.

The Mitochondrial Compounds research area is grouped by research field rather than by class. It brings together MOTS-c, a sixteen-residue linear peptide; SS-31, an aromatic-cationic tetrapeptide containing 2′,6′-dimethyltyrosine; and NAD+, a dinucleotide coenzyme.

The Neuropeptides research area pairs two synthetic heptapeptides, Semax and Selank, each a short sequence extended at the C-terminus by the tripeptide Pro-Gly-Pro.

Each research compound in the catalogue is supplied to one specification: ≥99% purity (HPLC). Purity is measured by HPLC, which separates the target peptide from closely related impurities such as truncated and deletion sequences, and identity is confirmed by LC-MS against the expected molecular mass.

Testing is independent. Independent third-party testing by PeptideVerify covers HPLC and LC-MS, and the reports prepared for British Peptide Labs are published in the COA Library, where you can open a certificate before you order. Each report is also linked from the product page it covers, and the quality page sets out how each compound is tested.

Each compound is supplied as a lyophilised powder in a sealed vial, and each product page lists its storage conditions, so the vial can go straight into your laboratory’s own storage on arrival.

Delivery is fast and free. Orders placed before 3pm Mon–Sat are packed the same working day and handed to Royal Mail Tracked 24. You get next-day tracked delivery with Royal Mail Tracked 24, each parcel is tracked from dispatch to delivery, and UK delivery is free on all orders. Cut-off times, delivery days and returns are set out on the delivery page.

Ordering is simple. Choose a compound and vial size on its product page, add it to your basket and check out as a guest, with no account to create. You pay by bank from your own banking app, and British Peptide Labs is a UK-registered company, so ordering, payment and support all run in pounds sterling from the UK. Support available 24/7 through the contact page.

The catalogue table has one row per compound, grouped by research area and sorted by name within each area. The Peptide column links to the product page, and the Research area column links to the page for that molecular class.

Sizes gives the range of vial sizes on offer, in milligrams per vial. From is the lowest current price for a single vial. Lowest £/mg divides each vial’s price by its milligram content and shows the lowest figure across the sizes. Price per milligram is the fairest way to compare UK peptide prices across different vial sizes and different suppliers, because a larger vial often carries a lower figure per milligram than a smaller one.

Purity gives the HPLC purity specification. CAS gives the Chemical Abstracts Service registry number and MW the molecular weight in grams per mole: the identifiers most laboratories use to match a compound against their own records and their own analytical data. Laboratory consumables are listed by volume.

To see where our prices sit in the wider market, the monthly UK research peptide price index tracks the price per milligram of common research peptides across UK suppliers. Set the Lowest £/mg column beside the index and you can judge value in seconds.

Buying research peptides in the UK from a UK supplier keeps the whole order simple: prices are in pounds sterling, parcels travel by Royal Mail Tracked 24 for next-day tracked delivery, and support is available around the clock. Repeat orders are just as easy, because each compound is listed to the same purity specification and the same identifiers each time, so a laboratory can reorder by name and vial size with confidence.

New compounds join the catalogue under the research area that matches their molecular class, so this page keeps the same structure as the range grows, and the table always shows the full catalogue on one screen.

Laboratory tools: peptide calculator (stock concentration arithmetic) and molarity calculator (conversion from mass concentration to molarity), plus the peptide reference data table of sequences, formulas and masses.
