Research peptide collection

Stocked kits and quote-only peptides

The shop lists every peptide we can supply, so it mixes two kinds of product. Stocked kits carry fixed prices per vial size and go to checkout like any other online order. Quote-only peptides are marked “On request”. We source these from partner synthesis labs when an order comes in, so price, minimum quantity and lead time are confirmed one to one over WhatsApp.

Use the “On request” filter to see quote-only listings on their own, or leave it off to compare everything in one grid. Sorting by price only applies to stocked kits, because quote-only items have no fixed price until we confirm availability.

Reading a product listing

Each listing shows the peptide name, the milligram amount per vial and the price of a 10-vial kit. The same compound often comes in more than one size. Larger vials usually cost less per milligram, but they are only better value if your protocol actually uses that amount before the material degrades once opened.

Product pages also show the research category, the CAS number or sequence where we have one on record, storage notes and any certificate of analysis we hold. If a field is missing, we do not have verified information for it, and we leave it out rather than guess.

Peptide terminology

Peptides are short chains of amino acids. The amino acid sequence defines the compound, and small changes such as an amidated end, a D-amino acid or an attached fatty-acid chain can give an analogue very different stability. “Lyophilised” means freeze-dried: water is removed under vacuum so the peptide can be stored and shipped as a dry powder.

Blends such as BPC-157 + TB-500 or CJC-1295 no DAC + Ipamorelin contain two peptides in one vial, and the listing states the amount of each. “DAC” (drug affinity complex) is a modification that binds blood albumin and extends half-life in published models. CJC-1295 with DAC and without DAC are therefore separate products, not two sizes of one.

What purity figures mean

Purity on a certificate of analysis normally comes from high-performance liquid chromatography (HPLC). The sample is separated into its components and the main peak is reported as a percentage of everything detected. Mass spectrometry is a separate test that confirms the molecular weight matches the expected compound. A useful report includes both.

A purity figure belongs to one batch. When comparing suppliers, check that the batch number on the report matches the vial and that the report can be verified with the laboratory that issued it. Our Janoshik testing page explains how to do this for the reports we publish.

Choosing between similar compounds

Many categories contain compounds studied for overlapping questions. Researchers usually choose between them on practical grounds: which receptor or pathway the published literature uses the compound to probe, its reported half-life in those models, its stability in solution, and whether a reference standard or published method already exists for the assay planned.

Category pages summarise these distinctions for each group, and individual product pages link to the reference literature we use. If you are not sure which listing matches the compound named in a paper, send us the paper's identifier and we will check it against our catalogue.

Supplies, storage and arrival

Lab supplies such as bacteriostatic water, acetic acid, benzyl alcohol and phosphate-buffered saline are listed alongside the peptides because most reconstitution methods need one of them. Bacteriostatic water suits most peptides. Some, such as IGF-1 variants, are commonly dissolved in dilute acetic acid in published methods.

When a parcel arrives, store the lyophilised vials refrigerated and out of light until use. Check vial seals and batch numbers against your order confirmation, and contact us within a few days if anything is damaged or missing, preferably with photos.

Prices, shipping and promotions

Prices are in euros per 10-vial kit. Shipping is charged once per order: €60 to Europe and the UK, €70 to the USA, Canada, Cyprus and the Middle East. Optional €40 shipping protection is offered at checkout. Delivery takes 5–18 business days from the tracking number being issued. Any running promotion applies to the product subtotal only, never to shipping or protection.

Getting help with a choice

If the grid has several listings that seem to match the compound in your paper, send us the paper's name or DOI, the sequence or CAS number, and the amount your method calls for. We will tell you which listing matches, whether it is stocked or quote-only, and which batch documentation we can supply. We answer on WhatsApp and by email, usually the same day.

For quote-only peptides, the enquiry button on each product page writes the message for you. It lists every size we can source with its price, explains that each option is a 10-vial kit, and asks which you need. You can edit the message before sending. There is no obligation to order after asking for a quote.

For institutional orders, larger quantities or recurring supply, mention it in your first message. We can group several compounds into one shipment so they travel under a single tracking number and shipping is charged only once per order.
