How should Cortagen be stored?

−20 °C, dry and protected from light; 2–8 °C after reconstitution. The storage note applies to the sealed product; see "Storage & handling" for details.

What is Cortagen dissolved in in the lab?

Lyophilized peptides are usually reconstituted in the lab with bacteriostatic water (BAC water) or sterile water. Calculate the resulting concentration with our peptide calculator. We give no dosing information.

Is there a lab report for Cortagen?

Yes. The current batch C208 was tested by Janoshik on 11/09/2026: HPLC purity 99.52 %. Open the full report above under batches or in the lab report archive.

How fast is Cortagen delivered?

We ship within 24–48 hours of payment. DHL delivers to Germany in 1–2 working days, to the rest of the EU in 2–6.

Is Cortagen intended for use in humans?

No. All products are intended exclusively for research and laboratory purposes and not for use in humans or animals.

Research profile

What is cortagen?

Cortagen is one of the synthetic short peptides described at the St Petersburg Institute of Bioregulation and Gerontology (430.4 g/mol). The idea behind these bioregulators is that short peptides influence gene activity in a tissue-specific way.

Research status

Work describes effects on gene expression and regeneration in models of peripheral nerve injury and in cell culture. A direct interaction with DNA is discussed but rarely confirmed independently; the literature comes mostly from one group.

Status

Not approved. Research use only. Other bioregulators: pinealon, cardiogen, vesugen.
