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.
Semax is a short neuropeptide of seven amino acids. It is built from a small fragment of a natural hormone, corticotropin, with a short three-residue tail added onto the end.
Vestrand supplies it as one lot at a time, prepared for independent purity testing, with the certificate published to its verification page.
That construction is the detail worth knowing: take a short piece of a natural hormone, add a small tail, and you have Semax. The added tail is what separates it from the plain fragment it starts from, and from a closely named but differently capped substance it is sometimes confused with.
For laboratory research use only. Not for human or veterinary use.
Semax is a synthetic heptapeptide built from an ACTH(4-7) fragment extended with a Pro-Gly-Pro tail, a melanocortin-derived neuropeptide. It is catalogued in neuropeptide 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.
