The study looked at skin sarcoidosis patients and tried several immune‑boosting drugs, including the peptide thymogen. None of the drugs, including thymogen, showed clear benefits on their own. The best results came from mixing steroids with another drug, but even then the disease came back in about one‑fifth of people after two years, and the medicines can have serious side effects. For most people interested in longevity or performance, this research doesn’t offer useful, safe ways to use thymogen.

Twenty-eight patients with skin sarcoidosis were treated with thymalin, thymogen, levamisole, dimocifon, with due consideration for their immune status. Immunostimulating therapy has failed. Plaquenil, phthivazide and duplex therapy did not result in noticeable improvement either. An individual pattern of mononuclear phagocyte response to various immunoregulators was revealed. The highest sensitivity to human interferon, hydrocortisone, and prospidine was determined in vitro. The highest effect was achieved by a combination of corticosteroids with prospidine, though in 20 percent of cases the disease recurred within 2 years. Since these drugs are not harmless for the body, the major indications for their prescription to patients with skin sarcoidosis (provided there are no direct indications because of other conditions) are the process activity and dissemination, cosmetic defects because of the disease. In case of a local involvement and uneventful course of the process a follow-up is advisable.
