DS Laboratories is the first biotech developer to synthesize and commercialize the astressin-B peptide for human use in a cosmetic.

Indeed, the astressin-B contained in Spectral.F7 is authentic. The DS Laboratories team of chemists worked quickly to develop it, and the company invested heavily to introduce it first. Spectral.F7 was released less than a year after publication of the peptide?s role in hair growth.
