5 entries in this category.

  • Glutathione

    Glutathione is the body's primary internal antioxidant, sold as an oral, IV, and intranasal supplement. It has real human clinical trial evidence for oral use in skin lightening and intranasal use in Parkinson's research, but many wellness and IV "whitening drip" claims circulating online outrun the published evidence.

  • PNC-27

    PNC-27 is a preclinical-only, p53-penetratin chimeric peptide studied in cancer cell lines and limited animal models for its ability to bind HDM-2 on cancer cell membranes and induce necrosis; it has never been tested in humans.

  • Thymogen

    Thymogen is a synthetic glutamyl-tryptophan dipeptide developed in Russia as a thymus-mimicking immunomodulator. It is a registered prescription drug in Russia but has no Western regulatory status, and independently verifiable clinical and dosing data outside Russian-language sources is very limited.

  • Thymosin Alpha-1

    Thymosin alpha-1 (thymalfasin, Zadaxin) is an immune-modulating peptide approved in China and other countries as a hepatitis B/C antiviral adjunct, but not FDA-approved in the US; a 2025 phase 3 trial found no mortality benefit in sepsis.

  • Thymulin

    Thymulin (FTS) is a naturally occurring, zinc-dependent nonapeptide thymic hormone studied since 1977 for T-cell development; it is a distinct substance from the similarly-named Russian peptide product "Thymalin" and has no approved human dosing regimen.
