A Russian nasal-spray peptide used after strokes and studied as a “brain booster”.
Registered as a medicine in Russia, where it is used after strokes and for some other brain conditions. Not approved in the US, UK or EU.
Semax is a lab-made fragment of ACTH, a hormone from the pituitary gland, with a short tail added so it lasts longer. It doesn’t have ACTH’s hormone effects.
It is thought to raise levels of BDNF, a protein that helps brain cells survive and form new connections.

Follow the manufacturer's batch-specific storage temperature and conditions.
Keep in original packaging, away from direct sunlight and excess heat.
Refer to the lot-specific expiry date and stability documentation. Shelf life should not be inferred from the product name alone.
For solvent compatibility or preparation specifications, request the manufacturer’s batch documentation. Research protocols should be established by qualified laboratory personnel.
Every product comes three ways. It's the same peptide and the same amounts; what changes is the packaging, what's included and the price. Choose the nasal spray in its VETUD box, a dual-chamber vial for the reusable pen, or a vial.

The freeze-dried peptide and the bacteriostatic (BAC) water sit in separate chambers, divided by a rubber stopper. They stay apart until the cartridge is used.
The dual-chamber vial fits the reusable VETUD pen, which comes in the pen kit box of the other VETUD peptides. The drive, dial and indicator window stay with the pen: when a cartridge is empty, fit a new dual-chamber vial.
Choose the vial if you already have bacteriostatic water and your own lab supplies. It's the lowest price for the same amount.

GuideConcentration & focus
Both nasal-spray peptides are registered in Russia, for stroke recovery and anxiety. The studies behind them are small, and few have been repeated elsewhere.
RegulationRegulation
A federal advisory panel looked at whether pharmacies should be allowed to make seven popular peptides. Here’s what happened, and what it does and doesn’t mean.
RegulationRegulation
BPC-157, TB-500, GHK-Cu and nine others are no longer on the FDA’s list of risky compounding ingredients. That isn’t the same as approval.
