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.
Storage and reconstitution
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.
Shipping within Canada
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. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
