How it works

Three steps from catalogue to bench

No account required to browse, and no minimum order.

01

Browse the catalogue

Research peptides, blends and research chemicals, grouped by category. Every listing publishes the compound’s CAS number, molecular formula, molecular weight, net contents per vial and its ≥99% purity specification.

02

Place the order

Check out over an encrypted connection. Volume pricing is applied automatically at 5 and 10 units, and qualifying domestic orders over $200 ship free.

03

Fast dispatch

In-stock orders placed before our daily cut-off are dispatched within 24 business hours, in plain packaging with no product details on the outside. Tracking follows by email; domestic delivery typically takes 2–5 business days.

Quality & testing

How our material is tested and specified

≥99% purity

Purity determined by HPLC

Every peptide in the catalogue is specified at ≥99% purity. Purity is determined by high-performance liquid chromatography (HPLC) at an independent third-party laboratory, independently of our own production.

The specification is published on the product page itself rather than held back for a datasheet request.

Why it matters

Purity is the share of the vial that is the target compound. A figure produced by a laboratory with no stake in the result is the only version of it worth comparing between suppliers.

Questions

Ordering, delivery and returns

Ordering & shipping

In-stock orders placed before our daily cut-off are processed and dispatched within 24 business hours. Orders placed at weekends or on holidays ship the next business day.

Shipping is calculated at checkout, and qualifying domestic orders over $200 ship free. Domestic delivery typically takes 2–5 business days after dispatch. Delivery estimates are not guaranteed and may be affected by carrier delays outside our control.

All orders ship in plain packaging with no product details visible on the exterior.

No. We do not misrepresent customs information under any circumstances. Buyers are responsible for any import taxes, duties or fees that apply where they are.

Returns & guarantees

Email [email protected] within 7 days of the expected or actual delivery date, with your order number and — for damage — photographs of the packaging and contents. If tracking shows a package is lost we will reship the order or issue a refund; if products arrive damaged we send free replacements. Cover requires that the address given at checkout was correct and complete.

Unopened, unused products in their original packaging may be returned within 30 days of delivery. Email us first for return instructions — returns sent without prior authorisation may not be processed. Products whose seals have been opened, or that have been reconstituted or otherwise handled, are non-returnable except where they arrived damaged or incorrect.

Research use

Everything we sell is supplied for laboratory and research use only. It is not a drug, is not intended to treat, diagnose, cure or prevent any disease, and is not meant for any cosmetic purpose. By ordering you represent that you are qualified to handle these materials in a research setting, and that they will not be introduced into humans or animals in any way.

You are responsible for the regulations that apply where you are, including on importation, purchase and possession. Nothing on this site is legal advice. See our Restricted Products & Compliance page and our Terms & Conditions.

No. We are a supply company, and research protocol questions are outside our scope. We do not comment on administration or on alleged effects of any product, and we will cancel an order and bar future orders where we believe a product is intended for human or animal use.
