Description
TB4 Fragment 1-4 Capsules provide Ac-SDKP, the N-terminal tetrapeptide of Thymosin Beta-4, in a convenient oral format. Each 60-count bottle from Limitless Life Nootropics is produced in the USA and verified by independent testing.
What Is TB4 Fragment 1-4 Capsules?
Ac-SDKP is one of the smallest biologically active fragments of Thymosin Beta-4. Its four amino acids (acetyl-Ser-Asp-Lys-Pro) are naturally released from the parent protein and have been studied for their influence on fibrosis, inflammation and blood cell production.
Short peptides like this one are more resistant to digestive breakdown than large proteins, which makes capsule delivery a practical choice for studies on systemic exposure and gut-related outcomes. Capsules also offer pre-measured consistency without weighing or reconstitution.
Researchers comparing delivery routes can pair this product with the lyophilized fragment in our catalog, allowing direct evaluation of oral versus parenteral formats using the same compound.
Key Research Areas
The scientific literature describes these capsules across several areas of investigation:
- Oral delivery of small anti-fibrotic peptides
- Organ fibrosis models in heart, kidney and liver
- Inflammatory cytokine regulation
- Bone marrow and stem cell proliferation studies
- Route-of-administration comparisons
Researchers can review peer-reviewed studies on Ac-SDKP through the National Library of Medicine (PubMed) database.
