Amino Club research peptides, verified batch by batch.

Purity is a claim until someone shows you the chromatogram. Each batch we receive is analysed by HPLC for purity and confirmed by mass spectrometry for identity, and the resulting Certificate of Analysis travels with the order rather than sitting behind a support request.

HPLC purity determination on every batch
Mass spectrometry molecular weight confirmation
Batch number on the vial matches the certificate
Certificates archived and retrievable by batch

How testing works

Common questions

Technical questions about handling, testing or shipping are answered by our research support team seven days a week.

Every compound in the catalogue is specified at ≥99% purity, which is the figure printed on the vial label. Purity is determined by High-Performance Liquid Chromatography and identity is confirmed by mass spectrometry. The exact figure for the batch you receive is stated on its Certificate of Analysis.

Yes. Every order ships with the batch-specific Certificate of Analysis for the vials in that order. It lists the batch number, test date, HPLC purity result and mass spectrometry identity confirmation. If you need the CoA before ordering, request it by batch number through the contact form.

Lyophilised powder is stable at -20°C for long-term storage and tolerates ambient temperatures during transit. Keep vials sealed and protected from light. Once reconstituted, store at 2-8°C and refer to the stability data for that specific sequence, which varies considerably between compounds.

Bacteriostatic water is the standard diluent, which we stock as Amino H2O. The volume required depends on the concentration your protocol calls for. Add diluent slowly against the vial wall rather than directly onto the powder, and swirl rather than shake.

We ship worldwide. Orders placed before 2pm on a business day are dispatched the same day via tracked courier. Delivery typically takes 2-4 business days domestically and 5-12 business days internationally, depending on destination and customs clearance. Packaging is discreet and unbranded.

Why laboratories order from Amino Club

A purity figure printed on a product page describes what a supplier hopes is true of a product line. It is not the same thing as a measurement of the vial in front of you. Amino Club works the other way round: every batch is quarantined on arrival, tested by HPLC for purity and by mass spectrometry for identity, and released only once those results are recorded against the batch number printed on the label. The Certificate of Analysis carrying that number ships with the order.

That is the whole proposition, and it is deliberately narrow. It means the material you cite in a methods section can be traced to the test results for the batch it came from, on a stated date, by a stated laboratory. The lab testing page sets out the process in detail, and about Amino Club explains why the business is built around it.

What you can order

The Amino Club peptides catalogue runs to 47 compounds across eight research areas, supplied lyophilised or, for a smaller group, ready to use in 15ml metered intranasal bottles. Bacteriostatic water for reconstitution is stocked alongside them. Orders placed before 2pm on a business day are dispatched the same day in discreet, unbranded packaging, and shipping is worldwide and free over $300. Laboratories buying in volume are quoted through bulk and wholesale.

Everything here is a laboratory reference material, supplied for in-vitro research only and never for human or veterinary use. We do not provide dosing guidance. See the research use policy, or ask research support anything the FAQ does not already answer. Published research on the compounds in this catalogue is indexed on PubMed.

Amino Club was built for laboratories that want the paperwork to match the vial. Every Amino Club order ships with its batch certificate, and every Amino Club listing states the purity it was released at.
