Thymosin Alpha-1, also known as thymalfasin, is a defined peptide of twenty-eight amino acids. It is filed in the senescence and cellular-longevity research collection.
We supply it as a single reference lot, prepared for third-party purity testing, with each lot's certificate on its verification page.
It pairs naturally with the thymus extract listed elsewhere in this collection: where that item is a mixture, this is a single, fully defined peptide — a clean, well-characterised reference standard of known length. That contrast is a tidy illustration of the difference between a defined compound and a heterogeneous extract.
