Frequently Asked Questions
Product Specifications
What is Semax Amidate?
Semax Amidate (N-acetyl Semax amidate) is a synthetic 7-amino acid heptapeptide with a molecular formula of C₃₉H₅₄O₁₀N₁₀S₁ and a molecular weight of 854.97 Da. The sequence Ac-Met-Glu-His-Phe-Pro-Gly-Pro-NH₂ features N-terminal acetylation and C-terminal amidation modifications with a Pro-Gly-Pro C-terminal extension. This product is supplied strictly as an analytical reference standard for laboratory research.
What is the difference between Semax and Semax Amidate?
Semax Amidate (N-acetyl Semax amidate) includes specific terminal modifications: acetylation at the N-terminus and amidation at the C-terminus. These structural modifications differentiate it from the unmodified form. Aventris supplies the amidate form as specified in the product documentation.
What is the difference between Semax and Selank?
Both are synthetic 7-amino acid heptapeptides with similar structural modifications (N-acetylation, C-amidation, Pro-Gly-Pro extension). Semax Amidate has the sequence Ac-Met-Glu-His-Phe-Pro-Gly-Pro-NH₂ (854.97 Da). Selank Amidate has the sequence Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH₂ (863.01 Da). Both are available from Aventris as separate analytical reference standards.
What analytical data is provided?
Each batch includes a comprehensive Batch Verification Report (BVR) containing all manufacturer analytical data: HPLC purity (99.79%), peptide content (95.64%), ESI-MS molecular weight confirmation (854.97 Da), mass balance (103.57%), Karl Fischer water content (2.44%), and acetate content (5.49%). Access via QR code or online verification portal.
How do I verify my batch?
Three methods: (1) Scan QR code on product label, (2) Click verification link in order confirmation email, (3) Visit aventrislabs.com/verify and enter batch ID. All provide instant access to your batch-specific Batch Verification Report with complete analytical data.
Why does the powder look smaller than other suppliers?
Aventris peptides are filler-free. Many suppliers add mannitol or other bulking agents to make the powder appear larger in the vial. Our vials contain only pure lyophilized peptide — nothing else. Less visible powder actually means a purer product with no unnecessary additives. Learn more at aventrislabs.com/peptide-fillers-explained.
What is the shelf life?
Typically 24 months when stored in sealed vial at -20°C or below, protected from light and moisture. Specific retest date listed on Batch Verification Report.
