Semax is a research-grade synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10). It is known for its ability to upregulate brain-derived neurotrophic factor (BDNF) and modulate neurotransmitter systems. It is designed for scientific study in cognitive function, neuroprotection, and neurorestorative research fields.
Semax is widely studied for its ability to impact:
Every batch is independently tested by a third-party laboratory for purity and identity using HPLC and mass spectrometry. A Certificate of Analysis (COA) is available for each product, with a batch number that matches the label on your vial — so you can verify exactly what you're receiving. We publish our testing because verification, not just claims, is what quality should be built on.
Our compounds are sold strictly for laboratory and research use only. They are supplied as research chemicals, not as drugs, supplements, or products for human or veterinary use. Buyers are responsible for complying with all applicable local, state, and federal regulations regarding their purchase and handling.
Orders are processed quickly — most ship within 24–48 hours — and arrive in discreet, protective packaging designed to preserve product integrity in transit. You'll receive a tracking number as soon as your order ships. During warmer months, temperature-sensitive items include cold-chain packaging.
Todos los pedidos son entregados en un plazo de 5 a 8 días hábiles. Proporcionamos seguimiento del pedido en tiempo real.

We stand behind the purity and identity of every compound, backed by its Certificate of Analysis. If there's an issue with your order — damage in transit, an incorrect item, or a discrepancy with the COA — report it within 30 days of delivery and we'll make it right. Due to the nature of these materials, opened vials cannot be returned.

Every peptide is synthesized and packaged in our U.S.-based facility. We don't outsource production overseas or rely on third-party fillers. By keeping the entire process in-house, we maintain full control over quality, consistency, and traceability from start to finish.
Each batch undergoes independent third-party testing for purity and identity. Every order ships with access to its Certificate of Analysis (COA), so you can verify exactly what you're receiving. We publish our results because transparency isn't optional — it's the standard.
