10 vials per kit, from 1 kit per strength. Values from our product table; each lot's measured results are on its batch COA.

How we sell

Kits of ten vials, quoted in writing.

How ordering works

10 vials per kit
One kit is ten vials of the same product at the same strength — lyophilized powder for the peptides.
From 1 kit
The minimum is one kit per product and strength; one order can combine several products.
Written quotes
Prices are tiered by the number of kits. The quote gives unit price, shipping and lead time; we reply within 24 hours.
Batch COA
Every lot of a stocked product has its own COA; for the peptides it reports HPLC purity, MS identity, endotoxin and fill.

Batch COA

Every lot has its own COA.

Every lot of a stocked peptide has its own certificate of analysis. Ask for the COA of the batch you are quoted before you order — the batch number on that COA is the batch we ship.

What the COA reports How to read a COA

On every batch COA

HPLC purityPurity against the specification, in %
MS identityMolecular mass of the peptide confirmed
EndotoxinResult reported with its unit
FillAmount of peptide per vial

Lot number

The COA names the lot, so it matches the vials you receive.

Agreed in writing

Any other test is agreed in the quotation before the order.

Report previews

Batch COAs and test reports, previewed.

Each picture is the first page at low resolution, with numbers, dates and signatures covered, so the small print cannot be read. The full, clear copy comes from sales — ask for it by product and strength.

Classification

Skin-Research Peptides by Class: Signal, Neurotransmitter-Modulating, Carrier and Enzyme-Inhibitor

A widely cited review groups topical peptides into four classes. Which peptides in our catalogue sit in which class, on what source, and what the class does not tell you about a vial.

SNAP-8® vs Argireline®: Sequence, Mass and COA Checks

Acetyl Octapeptide-3 and Acetyl Hexapeptide-8 share six residues and differ by two. Their sequences, formulas and masses side by side, how the MS result tells them apart — and how Palmitoyl Pentapeptide-4 differs from both.

Questions

What buyers ask first.

All questions

How many vials are in one kit?

One kit is 10 vials of the same product at the same strength. Each vial holds the stated amount, for example 10 mg of lyophilized peptide; the few solutions are stated per vial in mg or ml.

What is the minimum order?

1 kit per product and strength. One order can combine several products and strengths, each from 1 kit.

How are prices quoted?

In writing, per request. Prices are tiered by the number of kits of each peptide and strength; the quotation gives the unit price per kit, the shipping cost and the lead time. We reply within 24 hours.

What does the batch COA report?

HPLC purity, MS identity, endotoxin and fill, on the COA of every lot of a stocked peptide. The COA carries the lot number, so you can match it to the vials you receive.

Is there a third-party report?

Yes: HPLC purity and MS identity reports from a third-party analytical laboratory in Tianjin, China, on Acetyl Octapeptide-3 (10 mg), KPV (10 mg), Retatrutide (50 mg) and 5-Amino-1MQ (5 mg), and reports that customers commissioned from an independent laboratory on KPV (10 mg) and Retatrutide (20 mg, 60 mg). Low-resolution previews of the first page are on our Batch COA page and the product pages; the complete report is available from sales.

Where do orders ship from?

From China, by international express. The transit time to your country is stated in the quotation.

Ask for a quote.

Name the product, the strength, the number of kits and the destination country. We reply within 24 hours with the unit price per kit, shipping, lead time and the COA of the batch we would ship.
