−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.
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.
Yes. The current batch C206 was tested by Janoshik on 16/07/2026: HPLC purity 99.879 %. Open the full report above under batches or in the lab report archive.

No. All products are intended exclusively for research and laboratory purposes and not for use in humans or animals.
Testagen has four amino acids (447.4 g/mol). As with other bioregulators, the central hypothesis is that short peptides influence the activity of particular genes.
Work describes effects on gene expression and proliferation markers in cell culture and DNA binding models. The data are very limited and come mostly from one group.
Not approved. Research use only. Background on this peptide group is in Epitalon: what telomere studies show.
