SEMAXResearch-Grade Peptide · Lab-Verified Purity
Semax is Selank's cognition-focused sibling from the same Russian research program. Instead of calming, Semax is studied for sharpening — attention, memory, neuroprotection. It's a modified fragment of ACTH designed to survive breakdown and cross into the brain.

Everything researchers need to know about SEMAX
Manufacturing, testing, handling, and shipping details for SEMAX. For research purposes only — not for human or animal consumption.
SEMAX — Product Overview
Semax is Selank's cognition-focused sibling from the same Russian research program. Instead of calming, Semax is studied for sharpening — attention, memory, neuroprotection. It's a modified fragment of ACTH designed to survive breakdown and cross into the brain.
SEMAX — Molecular Characteristics & Vial Specifications
ProSource Labs supplies SEMAX in the following available vial sizes: 10mg. Each SEMAX vial contains pure lyophilized peptide — no fillers, no bulking agents. Product SKU references: SMAX-10MV.
- Cognition Focus: Attention, memory, and mental-clarity effects in study models
- BDNF Booster: Studied for elevating brain-derived neurotrophic factor
- Neuroprotective: Rodent stroke-model literature shows protective effects
- Nasal Preferred: Most research protocols use intranasal delivery
Batches are characterized by ESI mass spectrometry to confirm molecular weight against the theoretical value, with amino-acid sequence confirmation on selected QA lots. Peptide content assay distinguishes net peptide mass from residual counter-ion salt.
SEMAX — Laboratory Handling & Storage
Lyophilized SEMAX vials should be stored at -20°C (or colder) in a laboratory freezer, inside the sealed factory container. Minimize warm-up cycles — move only the specific vial needed for a given experiment out of frozen storage at a time.
All laboratory handling of SEMAX should follow the receiving institution's SOPs and applicable peer-reviewed protocols relevant to the researcher's specific experimental question. ProSource Labs does not publish end-user preparation or usage instructions.
SEMAX — Third-Party Analytical Testing
Every batch of SEMAX released by ProSource Labs undergoes independent reverse-phase High Performance Liquid Chromatography (HPLC) — the industry-standard analytical method for this class of research compound. Target chromatographic purity is typically ≥ 99%.
Additional characterization may include ESI mass spectrometry for molecular weight confirmation, Karl Fischer titration for residual moisture, and appearance/solubility inspection. A batch-specific Certificate of Analysis (COA) is available on request through customer support after purchase.
SEMAX — Quality Assurance Process
Each production lot of SEMAX is quarantined pending analytical release, tested against documented purity, identity, and moisture acceptance criteria, and only released to sellable inventory after passing every QA checkpoint. Batches that fail any single criterion are quarantined and never reach customer-facing inventory.
If a vial of SEMAX you received from ProSource Labs ever fails your own institution's incoming QA testing, contact customer support at support@prosourcelabs.org — we retain samples of every batch for cross-verification.
SEMAX — Typical Research Application
Widely used in studies on cognition, BDNF/TrkB signaling, brain plasticity, and stroke protection. Extensively studied in the Russian neuroscience corpus.
SEMAX — Packaging & Fast Southern California Shipping
SEMAX vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.
Every SEMAX shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
