The Vita-Cos-Med Klett-Loch GmbH is since 35 years successful engaged in research, development and distribution of healthcare products with patented non-animal thymic peptide agents - a mimicry of the natural thymic total extract. Thymic therapies are used successful in medical practice since decades. Now, the active ingredients GKL-02/03 allow the application of thymic-therapies – without the use of ingredients of animal origin. In-company research in the pharmaceutical and cosmetic field started in 1976, and in 1981 the company was able to demonstrate the unique effectiveness of the low molecular thymus hydrolysate GKL-01 in treating androgenetic hair loss. Since then the brand Thymuskin® is regarded as one of the leading preparations worldwide for counteracting hair loss and encouraging the formation of new hair. Further pharmaceutical innovations such as the development of the bovine-free low molecular, statistical thymic peptide library GKL-02 and numerous other pharmaceutical patents and products have followed. Another major success was the introduction of Thymrevit® Revitalizing Capsules in 2008. This dietary supplement for special medical purposes has helped many people since in the treatment of diseases associated with immune disorders and immune weakness. Right from the beginning we have supported the technology transfer of biochemical innovations in close cooperation with universities and teaching hospitals. The findings available to date underline the success of the route we have taken and our work.
