Why buy Semax Peptide from TrueBond Labs
An independent certificate
An independent third-party lab tested our published Semax lot, reported HPLC purity of at least 99% and confirmed identity. Open the Semax certificate of analysis, compare its lot code with the one on your vial, then save the PDF with your records.
Built on ACTH(4-7), 10mg
Semax is a seven-residue peptide built on a short fragment of ACTH. We supply it as 10mg of freeze-dried powder in a sealed 3 mL vial, with the lot code printed right on it. It's the only size we stock, the same as Selank.
Semax or Selank
Semax often comes up alongside Selank. Both end in the same Pro-Gly-Pro tail but start from different parent sequences, and each has its own certificate. Our research peptides page groups everything we carry by research area.
What is Semax?
Semax is a synthetic peptide of seven amino acids: Met-Glu-His-Phe-Pro-Gly-Pro. The first four match positions 4 to 7 of ACTH (adrenocorticotropic hormone), and a Pro-Gly-Pro tail completes the chain. ACTH itself is 39 amino acids long, so Semax borrows only a short stretch of it.
Semax appears in published laboratory research on neuropeptide signaling. Its closest relative in our catalog is Selank, which shares the tail but starts from tuftsin instead of ACTH.

Semax Peptide: frequently asked questions
What is the difference between Semax and Selank?
They're closely related heptapeptides, and both end in Pro-Gly-Pro. Semax starts from a fragment of ACTH (Met-Glu-His-Phe). Selank starts from tuftsin (Thr-Lys-Pro-Arg). So they share a tail but not a head. For the full side-by-side, see our Selank vs Semax comparison.
Is Semax the same as ACTH?
No. ACTH is a 39-amino-acid peptide. Semax borrows only positions 4 to 7 of it (Met-Glu-His-Phe) and adds Pro-Gly-Pro, so it's a seven-residue compound with its own name, lot codes and certificate.
How do I check the certificate for my Semax vial?
Look for the lot code printed on your vial, then search for it on our lab reports page. If it's listed, the certificate under that code covers your lot, with the full PDF to open and keep.
How should I store Semax?
Store the sealed vial in a freezer at −20°C (−4°F). Lyophilized Semax kept that way holds for 24 months or more. Keep it out of the light and avoid repeated freezing and thawing.
