Product Information
Total Active Ingredient: 600mg (10mg per capsule × 60 capsules)
Semax Capsules | ACTH-Derived Nootropic Neuropeptide, Research Grade
Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a synthetic heptapeptide derived from the ACTH(4-7) core sequence, registered as a drug in Russia for stroke and cognitive impairment treatment. This oral capsule format (10mg per capsule, 60 capsules) provides a stable delivery method for research examining BDNF regulation, neuroprotection, and cognitive biology.
Mechanism of Action
- BDNF and NGF upregulation, significantly increases brain-derived and nerve growth factor expression in hippocampus and cortex
- Dopaminergic modulation, enhances dopamine turnover in prefrontal cortex, relevant to working memory and attention models
- Neuroprotection, reduces ischaemia-induced neuronal death and inflammatory cytokine release in stroke models
- HIF-1α pathway, modulates hypoxia-inducible factor signaling under oxygen-glucose deprivation conditions
Research Areas
Semax is studied in stroke recovery, cognitive impairment, ADHD models, anxiety, and neuroprotection research. Frequently paired with Selank as a complementary neuropeptide pair and with Dihexa for synaptogenesis research.
Independent Lab Verification
Rainbow Peptide works with independent, accredited third-party laboratories, including Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01), to verify compound identity and purity. A Certificate of Analysis is included with every order.
For Research Use Only. Rainbow Peptide supplies this compound exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
Frequently Asked Questions
- What is Semax Capsules (10mg)?
- Semax ACTH-derived nootropic neuropeptide in oral capsule format, 10mg per capsule. Studied for BDNF upregulation, cognitive enhancement, and stroke recovery models. COA included.
- Is Semax Capsules (10mg) for sale at Rainbow Peptide?
- Yes. Semax Capsules (10mg) is available for purchase with Certificate of Analysis confirming >98% HPLC purity. Every order Overnight and 2–3 day delivery available. For Research Use Only.
- What purity is your Semax Capsules (10mg)?
- Rainbow Peptide's Semax Capsules (10mg) is >98% pure, HPLC verified through independent third-party laboratory testing, including work performed by Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01). A COA is included with every order.
- What does the Certificate of Analysis actually verify?
- A COA reports identity (confirming the compound is what it's labeled as, via HPLC-UV/VIS matched against a reference standard) and assay/content (the measured purity percentage). Together, this verifies a batch matches its labeled specification, rather than relying on a purity claim alone.
- Is Semax Capsules (10mg) safe for human use?
