Verification
Every batch is identified by a lot number, and its third-party certificate is listed here by lot. Measured values are shown only when they are real and independently verifiable.
Third-party testing in progress
We are currently having this product independently tested by a third-party laboratory. Its certificate of analysis will be published here as soon as the results are available — please check back soon. For laboratory research use only.
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-characterized reference standard of known length. That contrast is a tidy illustration of the difference between a defined compound and a heterogeneous extract.

Thymosin Alpha-1 (thymalfasin) is a defined 28-residue thymic peptide studied in immune-signaling research. It is the single-molecule counterpart to the thymus extract in its collection and is catalogued in senescence and cellular-longevity research.

Peptide
A short synthetic peptide corresponding to a tail-end fragment of human growth hormone, with one extra building block added at the front.
Peptide
A synthetic peptide of fifteen building blocks (a pentadecapeptide), based on a partial sequence of a protein first identified in gastric juice.
Peptide blend
A blend of two peptides — BPC-157 and TB-500 — supplied together. A mixture, not a single substance, with no identity of its own.
Peptide
A growth-hormone-releasing factor analogue of twenty-nine building blocks, also known as Modified GRF (1-29). Easily confused with the closely related sermorelin.
