Here the synthetic seven-residue peptide Semax comes dissolved in water and ready to use, in a 15 mL bottle with a metering pump. (Identity: Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0.) Semax started from the ACTH(4–10) fragment of adrenocorticotropic hormone, to which three residues — Pro-Gly-Pro — were added at the carboxyl end. That single change removes the parent hormone's action on the adrenal glands and also protects the peptide from the exopeptidases that would otherwise remove a short linear chain within minutes.
The 15 mL bottle comes in two fills — 10 mg (about 0.67 mg/mL) or 20 mg (about 1.33 mg/mL). As the solution is pre-formulated, labs comparing intranasal delivery with injected or oral formats can start from a documented concentration without weighing and reconstituting in between, removing a common source of variation between sessions.

Questions about Semax Nasal Spray
What quantity of Semax does each bottle hold?
Both come in a 15 mL bottle: 10 mg of Semax gives about 0.67 mg/mL, and 20 mg gives about 1.33 mg/mL. Your bottle's precise concentration appears on its label and again on the lot's Certificate of Analysis.
Is the Semax independently analysed, with a COA?
Yes. The peptide in the formulation is tested by an independent lab with HPLC to ≥99% purity and identity-confirmed by mass spectrometry; its lot Certificate of Analysis is available. Always compare the bottle's lot number with the COA before recording data.
What is Semax in chemical terms?
A synthetic seven-residue peptide — Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0, C37H51N9O10S, 813.93 g/mol — an ACTH(4–10) analogue lengthened with Pro-Gly-Pro, which slows enzymatic breakdown and has no adrenal-stimulating activity.
Must the spray be reconstituted?
No. It arrives pre-mixed and ready to use — the key practical difference from the lyophilised Semax vial. Skipping reconstitution removes weighing and dilution errors from experiments comparing formats or routes.
