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.
It means these compounds are supplied for in-vitro laboratory research only. They are not medicines, have not been evaluated for safety or efficacy in humans, and must not be used for human or veterinary purposes. By ordering you confirm you are a qualified researcher or institution and accept responsibility for lawful handling in your jurisdiction.
Yes. Tiered pricing is available for repeat volume, and we supply universities, private laboratories and contract research organisations with purchase-order terms. Send your compound list and quantities through the bulk enquiry form for a quote.
More research peptide FAQ answers
This research peptide FAQ is updated as questions come in, so anything asked often enough ends up here rather than being answered privately one message at a time.
Does Amino Club sell bacteriostatic water?
It is the most searched question in this research peptide FAQ, so it comes first.
Yes. Bacteriostatic water is stocked in 10ml vials with 0.9% benzyl alcohol as the preservative, USA sourced, so a single vial can be drawn from repeatedly under normal aseptic technique. It sits in the lab supplies group and ships alongside the rest of your order.
Why are peptides supplied as a powder rather than a solution?
Lyophilised powder is the most stable form for transit and storage. Sealed vials tolerate ambient temperature in transit and are held at -20°C long term. A solution begins degrading from the moment it is made, at a rate that differs for every sequence, so shipping powder puts that clock under your control rather than ours. Stability literature for individual sequences is indexed on PubMed.
How do I reconstitute a vial?
Add diluent slowly against the vial wall rather than directly onto the powder, and swirl rather than shake. Shaking introduces shear and foaming, both of which can damage a peptide. Storage guidance for the reconstituted solution is given on each individual product page, because stability varies considerably between compounds and a single blanket figure would be wrong for most of them.
Can I see the Certificate of Analysis before I order?
Yes. The certificate for the batch you are sent travels with the order, but if you need to see one first, or you need the certificate matching a batch you already hold, ask research support with the batch number. The lab testing page explains how each batch is tested and released.
Do you ship internationally, and who pays customs?
We ship worldwide, with free delivery on orders over $300. On international orders you are the importer of record, so any customs duty or import charge is payable at your end. Delivery estimates by region are on the shipping and returns page.
Do you offer pricing for laboratories buying in volume?
Yes, through bulk and wholesale, which covers tiered pricing from ten units per compound, purchase orders and invoiced terms for institutions, and consolidated certificates across a multi-batch order.
What does research use only actually mean?
It is the single most important line in this research peptide FAQ. It means these compounds are laboratory reference materials and nothing else. They are not medicines, not supplements, and not for human or veterinary use, and we do not provide dosing guidance or administration protocols of any kind. The obligations you accept when you order are set out in the research use policy.
If your question is not covered by this research peptide FAQ, ask Amino Club research support directly. Answers that come up repeatedly are added to the research peptide FAQ, so the next person does not have to ask Amino Club the same thing.
