Calm without the fog. Sharp without the edge. Selank is studied to reduce anxiety without sedation, clouded thinking, or dependency — so mental performance stays high while the stress falls away.
Every batch of Semax is run through High-Performance Liquid Chromatography. The chromatogram confirms purity percentage and identifies any impurity peaks. Our minimum standard is ≥99% by HPLC, verified by accredited third-party laboratories on every production batch.
Mass spec confirms the molecular weight of Semax matches the theoretical value exactly. This verifies the compound identity, confirming it is not a substitute or mislabeled product.
Endotoxin testing ensures the compound is free from bacterial contamination. Combined with HPLC purity and MS identity confirmation, this is the full three-point verification used by accredited research labs.
