What to Check When Your Semax Arrives
Not every irregularity on arrival is a defect, and not every compound is defective under the same conditions. Here is what actually matters when a Semax shipment arrives.
In plain English
Small molecules travel well and a warm journey is not a concern. One quirk: at low fill weights the freeze-dried powder can be a barely visible film on the glass. That is normal, not an empty vial.
What Semax actually is
Semax was built in a Moscow laboratory by taking a four-amino-acid piece of ACTH — a stress hormone — and adding a short tail so enzymes could not destroy it within seconds. That piece was chosen specifically because it carries nerve-related properties without the hormonal effects of the full molecule.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Arrival inspection for Semax
Small peptides ship well and ambient transit is not a defect signal. Check that the cake is present and intact — at low fill masses the lyophilized cake can be a thin film that is easy to mistake for an empty vial.
Storage on arrival
Documentation to check
Verify the molecular ion at 813.9 Da and check for a +16 Da oxidised species. For a peptide this short, RP-HPLC resolves related substances well, so a clean single peak is a strong quality signal.
What Semax is studied for
One of the most-cited research findings is upregulation of brain-derived neurotrophic factor in animal models.
A substantial Russian literature examines the compound in cerebral ischemia models.
Investigated in behavioural models measuring attention and memory consolidation.
The ACTH(4-7) fragment was selected specifically because it lacks the hormonal activity of the full sequence.
