TB4 Thymosin Beta 4

TB4 (Thymosin Beta 4 Fragment 1-4, Ac-SDKP) is a synthetic research peptide designed for scientists exploring advanced cellular and molecular pathways. This naturally occurring tetrapeptide, derived from thymosin Ξ²4, has gained significant attention in the lab for its potential roles in supporting healthy tissue environments, angiogenesis, and balanced inflammatory responses β€” all within controlled research settings.

Each serving delivers 500 mcg of Ac-SDKP, combined with 3 mg of SNAC (salcaprozate sodium) as a research excipient to aid in experimental delivery methods. Supplied in easy-to-use capsules, TB4 from Nutrition Labz Science ensures high purity, consistent quality, and convenient handling for researchers.
