You will notice there are no rupee or dollar figures on this page, and that is deliberate. A published price for a research peptide is misleading in most cases: the number that matters to a buyer is cost per milligram of active peptide, and that depends on purity grade, counter-ion, peptide content, pack format and order volume simultaneously.
What we can give you instead is the structure — how the tiers work, what moves the price, and what a quote will contain — so you can compare our offer against anyone else's on equal terms.
What sets the price
| Driver | Effect |
|---|---|
| Sequence length and complexity | The single largest factor. Cost scales roughly with residues, synthesis steps and purification difficulty. |
| Modifications | PEGylation, cyclisation, biotinylation and fluorescent labelling each add a step and a purification burden. |
| Purity grade | Standard, Verified and Characterised are materially different products, not the same product with a different label. |
| Characterisation depth | Mass spectrometry, endotoxin, residual solvents and amino acid analysis each add analytical time and cost. |
| Order volume | The band you move into matters more than the absolute quantity. |
| Pack format | Single vial, kit with bacteriostatic water and syringes, or bulk. |
| Counter-ion | TFA is the default; acetate or HCl changes the synthesis route. |
| Delivery terms | EXW, FOB, CIF or DAP — freight and insurance are a large share of landed cost at small volumes. |
Volume tiers
We operate on three commercial bands. The tier a buyer sits in depends on the total value of the order and the mix of SKUs, not on the number of vials alone.
- Trade — the entry band for institutional buyers and research organisations. Single SKU orders and first-time qualification lots.
- Volume — recurring multi-SKU supply. This is where the unit economics change materially, and it is the band most distributors should be planning toward.
- Contract — annual supply agreement with scheduled deliveries, committed volume, a named account manager and agreed price validity across the term.
Exact thresholds are set per sequence and per grade, because a high-value long sequence and a short reference standard do not sit in the same band at the same vial count. A quote states the tier and the next break explicitly, so you can see what the next commitment is worth.
Mixing SKUs counts
Order consolidation is where most B2B buyers leave money on the table. A mixed order across several SKUs at a given total value usually reaches a better band than the same total spent on one SKU, because the supplier amortises documentation, freight and QC across more material.
We consolidate multiple SKUs into a single export shipment with a single document pack and a single freight booking. On a mixed order of eight to twelve SKUs, the freight and documentation saving alone is frequently larger than the discount on the material.
What a quote contains
- Unit price per SKU at the quoted grade
- Quantity breaks, with the volume at which the next band applies
- Lead time per SKU, distinguishing stock from custom synthesis
- The analytical specification — every test to be performed, stated
- The document pack that will ship with the consignment
- Incoterm and named place
- Payment terms
- Price validity period
That is the same list as in our guide to writing an effective RFQ — because a quote that omits any of them cannot be compared fairly.
Annual supply agreements
For buyers with recurring demand, an annual agreement is usually worth more than chasing spot pricing. What it buys you:
- Agreed pricing across the term, protected from spot movement
- Scheduled monthly or quarterly deliveries with reserved capacity
- A named account manager who knows your specification
- Priority allocation on constrained sequences
- A standing document pack template, so each shipment ships without a request from you
- Agreed claim and replacement terms for a lot that fails verification
Distributors and institutional buyers typically start on a trial or trade band, qualify on two or three SKUs, and move to a contract band once the reorder pattern is established. Our distributor programme sets out how that progression works and what it includes.
Requesting a quote
Send the SKU list, quantity, grade, destination and incoterm. You will get a formal quotation back, normally within one business day, with the specification and lead time stated — no sales call required first.
B2B trade only — request a quote
All peptides are research-grade, for in-vitro use only, and supplied against a valid drug licence. Tell us your sequence, quantity and destination and the trade desk will respond within one business day.
