OS-01 research capsules

OS-01 Capsules – 100mg

Epigen X (OS-01) Capsules – 100mg. OS-01 is a lab-developed peptide first characterized in topical/dermal research contexts by its originating company as a senescence-related signaling candidate; published literature on the compound remains early-stage and has not been established in oral/capsule research contexts. Supplied at research-grade purity for laboratory use only.

$300.00

OS-01, marketed here as Epigen X, is a synthetic peptide first developed and characterized by the skin-biology company OneSkin Technologies. The published literature on OS-01 to date is early-stage, originates predominantly from its originating company’s own research program, and — importantly — has been generated almost exclusively in topical/dermal application contexts (cell culture, ex vivo human skin models, and small pilot topical-formulation trials). No published research has established the compound’s behavior, stability, or activity when taken orally or in capsule form, and the summary below should be read with that limitation in mind.

What is OS-01?

OS-01 is described in the originating company’s published materials as a senotherapeutic peptide — one studied for its relationship to cellular senescence markers and epigenetic-age signatures (DNA methylation clock measures) in cultured and ex vivo human skin tissue. Because OS-01 is a proprietary compound without a widely published synthesis route, First Class Science does not list a CAS number, molecular formula, or molecular weight for this material; researchers should independently confirm compound identity and purity using the batch Certificate of Analysis and their own analytical methods before use.

Storage: Store in a cool, dry place away from direct sunlight and moisture. Keep out of reach of children.

Important: This item is manufactured strictly for research purposes. It is not intended for human or veterinary use and is distributed solely for laboratory and scientific investigation.

Research Applications

Early-Stage Dermal & Cellular Senescence Research

Published pilot research — including a small vehicle-controlled topical-formulation study and a separate 12-week pilot trial referenced in the cosmetic-dermatology literature — has reported associations between topical OS-01 application and measures of skin barrier function, hydration, and epigenetic-age markers in the skin samples and participant groups studied. Study authors describe these as early, preliminary findings requiring larger and independently replicated trials, and caution that mechanism-of-action work is still ongoing. This body of research pertains specifically to topical/dermal use; it does not describe or support any expectation of activity, absorption, or effect from oral or capsule-form administration, which has not been studied.

Disclaimer: The research summarized above is drawn from third-party published studies conducted in animal, in vitro, or non-U.S. clinical contexts.
