Protocol
Storage & Handling
Long-Term Storage
Store lyophilized peptide at −20°C. Under these conditions the product remains stable for up to 24 months from the date of manufacture.
After Reconstitution
Once reconstituted, store at 4°C and use within 30 days. Avoid repeated freeze-thaw cycles as this may degrade compound integrity.
Shipping Conditions
All orders ship in insulated packaging with cooling packs to maintain the cold chain during transit. Free on every order, no minimum required.

Frequently Asked Questions
Semax is a synthetic heptapeptide analog of ACTH(4-10) developed in Russia at the Institute of Molecular Genetics. Unlike ACTH, semax lacks hormonal activity and acts through CNS pathways, primarily studied for neuroprotection and cognitive effects. It reflects semax's original development context in cerebrovascular disease research.
Semax has been approved in Russia and several CIS countries for stroke and cognitive disorders treatment. It does not have FDA or EMA approval. Our research-grade semax is strictly for in vitro laboratory research. Not for human or animal consumption.
Semax acts through ACTH-related CNS pathways and is primarily studied for neuroprotection, BDNF upregulation, and cognitive enhancement. Selank is a tuftsin analog studied for immune modulation, anxiolytic, and stress adaptation effects. Together they address complementary neuroimmune pathways — which is why they are frequently co-researched.
Add bacteriostatic water slowly along the vial wall, gently swirl until dissolved. Semax dissolves readily. Use our Reconstitution Calculator for volume guidance.
Our semax is verified at ≥98% purity via third-party HPLC analysis. The current batch is confirmed at 99.68% by Apex Analytics Lab. A full COA ships with every order.
