Sourcing
Compounds are produced by solid-phase peptide synthesis and received with the manufacturer's accompanying analysis for review.
About
Flux Peptides supplies lyophilised research peptides from within Canada, with a published purity specification and a batch reference on every order.
Canadian researchers ordering peptides have historically had two options: import from overseas and accept multi-week customs delays with no recourse when a vial arrives compromised, or pay institutional supplier prices that put routine exploratory work out of reach.
Flux Peptides exists to close that gap. We hold stock in Canada, we publish the specification we test against, and we attach a batch identifier to every order so a result recorded today can be traced to the exact material that produced it.
We are a small operation and we prefer to be direct about what that means. We do not synthesise in-house. We source from established manufacturers, verify what arrives, and take responsibility for storage and handling from that point until it reaches you.
Every enquiry is answered by someone who can actually look up your batch. There is no ticket queue and no outsourced support desk.
The standard
A purity figure is only meaningful if you know how it was produced. This is the sequence behind the number on the product page.
Compounds are produced by solid-phase peptide synthesis and received with the manufacturer's accompanying analysis for review.
Purity is assayed by high-performance liquid chromatography against a minimum 99.0% specification. Material below specification is not released.
Lyophilised material is sealed and held at minus 20 degrees Celsius, protected from light, until an order is packed.
The batch identifier is recorded against your order, so repeat purchases can be matched to the same reference in your notes.
Because orders leave from a Canadian facility, domestic shipments never enter the customs process. That removes the single largest source of delay and of temperature excursion for Canadian researchers, and it means a parcel that goes missing can be traced with a domestic carrier rather than written off.
We think being explicit about the limits matters more than marketing language, so to be clear:

New to ordering research peptides in Canada? Our buying guide covers what to verify before you order from anyone, including us. Or browse the catalogue.
We keep the range deliberately narrow. Twelve compounds is not a limitation we are apologising for, it is the number we can hold in proper cold storage, verify consistently and actually answer questions about. A catalogue of two hundred lines would mean drop-shipping most of them, and at that point the purity specification on the page stops describing anything we control.
A compound earns a place when there is genuine and sustained research demand for it in Canada, when we can source it from a manufacturer whose analysis stands up to review, and when it is stable enough to survive domestic transit without specialised handling. If any of those three fails, we would rather not list it than list it with caveats buried in the fine print.
Batches that come in below our stated specification are not released, are not discounted, and are not quietly sold as a lower grade. They are held and returned or destroyed. This occasionally means a compound goes out of stock rather than shipping something we would not want cited in someone's records, and we would rather explain a delay than a discrepancy.
If you have already bought from a batch that a later check calls into question, we contact affected customers directly rather than waiting for someone to notice. That is the practical reason we record the batch identifier against your order.
Ask us about the analysis for your batch, our storage and handling between receipt and dispatch, where a compound was manufactured, expected stock timing, or how to reach a person rather than a form. Those are all things a supplier should be able to answer plainly, and if we cannot answer one we will say why rather than deflect. What we will not do is advise on dosing, administration or anything involving living subjects, for the reasons set out in the disclaimer.
