View brandDetailed compound information
Semax is a synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-10). Research models show it rapidly upregulates BDNF and NGF in the hippocampus and cortex, and modulates enkephalin degradation. It is used experimentally in Russia for stroke recovery and cognitive research endpoints, and remains a standard investigational tool for neurotrophic pathway research.

Après une mauvaise expérience avec un autre fournisseur l'année dernière j'étais sceptique. Livraison rapide, emballage scellé et étiqueté correctement, certificat d'analyse joint à la commande. La qualité justifie le prix.
What you read on the page is exactly what you get. No bait and switch, no weird substitutions, no missing items. They emailed updates at every step and the product looks and works exactly as advertised. I appreciate the transparency.
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
Reconstitute the 5mg vial with 1mL bacteriostatic water → 5 mg/mL. On a U-100 insulin syringe, 6 IU = 0.06 mL = 300 mcg. Nasal spray presentation (if selected) is pre-calibrated per-actuation.
Switched over after my last vendor product seemed off — wrong color, late shipping, no documentation. Night and day difference here. Sealed properly, lot number matches the docs, and the product is doing what it is supposed to. Glad I switched.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
We currently operate on an inquiry-based ordering system. Submit your order through checkout and our team will contact you within 24 hours to confirm details and arrange payment. We are working on integrating direct payment options for a seamless experience.
