About Cortagen 20mg
Cortagen differs from Cardiogen by a single residue, leucine in place of arginine at the C-terminus, and that minimal difference is what the Khavinson framework holds responsible for tissue specificity. Reported research covers cortical neuron cultures and models of peripheral nerve injury, where effects on regeneration markers are the primary endpoint. The same caveats that apply across this peptide family apply here: the primary literature is largely Russian-language and independent replication outside the originating institute is sparse.
Storing and handling Cortagen 20mg
Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Cortagen 20mg questions
Are research peptides like Cortagen 20mg legal in Canada?
Cortagen 20mg is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.
Is Cortagen 20mg shipped from within Canada?
Yes. Every Cortagen 20mg order leaves British Columbia, Canada and travels entirely within the country. Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.
Does Cortagen 20mg come with a certificate of analysis?
Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every Cortagen 20mg lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.
How is Cortagen 20mg supplied and stored?
As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.
What fill is Cortagen 20mg supplied in?
Cortagen 20mg is supplied in a single 20mg fill, released against a >99% specification.
