Quality & Documentation

Every Vial Ships With Data, Not Promises

Peptides are only as good as the lot in your hand. Each batch is sampled before lyophilization, re-tested after filling, and released against a written specification — with the raw chromatogram and mass spectrum attached to the COA.

  • HPLC chromatogram and MS spectrum in every COA
  • Peptide content by UV, acetate and TFA content reported
  • Endotoxin and sterility testing on request
  • Retained samples kept 24 months for traceability

Why Buyers Stay

Built for Repeat Research Supply

In-House Synthesis

Solid-phase and fragment condensation runs from 100 mg to multi-kilogram batches.

Controlled Lyophilization

Validated freeze-drying cycles give a uniform, easily reconstituted cake.

Purity You Can Audit

HPLC, ESI-MS and amino-acid analysis data issued with the lot, not on request.

Custom Sequences

Modified residues, fluorescent labels, biotinylation and cyclization on request.

Fast, Tracked Shipping

Express dispatch within 48 hours, cold packs on request, tracking to your door.

Stock & Volume Tiers

Standing stock on 40+ sequences, with contract pricing for repeat programmes.

Shipping & Handling

From Our Freeze-Dryer to Your Bench

Lyophilized peptides are stable at ambient temperature, so most orders ship by express courier with tracking. Bulk and temperature-sensitive items go by air or sea freight with the documentation your customs broker expects.

FAQ

Questions Buyers Ask First

What is your minimum order quantity?

One kit of 10 vials for catalogue items, and 50 mg for bulk powder. Custom sequences start at 10 mg with a synthesis fee that is credited against larger orders.

What does the COA include?

Batch number, appearance, HPLC purity with the chromatogram, ESI-MS spectrum, molecular weight, water content, acetate content and storage conditions. Endotoxin and sterility results are added when those tests are ordered.

Are these products for human use?

No. Everything we supply is sold strictly for laboratory research and development. Products are not medicines, cosmetics or food ingredients, and we do not supply them for human or veterinary consumption.

Can you synthesise a custom peptide?

Yes. Send the sequence, modifications, purity target and quantity. Most custom sequences are quoted within 48 hours and delivered in 2 to 3 weeks depending on length and modifications.

Which payment methods do you accept?

Bank transfer (T/T) and major cryptocurrencies — USDT, USDC and Bitcoin (ETH and others on request). Crypto is settled 100% in advance; T/T can be 50/50 for larger orders. Wallet and bank details are confirmed on the proforma invoice only, never in an email signature.

How are the vials shipped?

Vials are packed in foam-lined cartons with a neutral outer label. Express delivery takes 3 to 7 days with tracking. Cold packs are added free of charge when you request them.

Need a price on a specific sequence?

Send the peptide, quantity and destination — you will have a quotation within 12 hours.
