Semax Selank blend UK is Crown Peptides' dual-peptide research formulation combining Semax and Selank, supplied in 5mg/5mg vials for laboratory research into neurotrophic, GABAergic and stress-related signalling.
Supplied for laboratory research purposes only — not for human consumption or for medical, veterinary or diagnostic use.
The Semax + Selank blend combines two synthetic peptides used in neurobiological research. Semax is associated with ACTH-fragment-derived neurotrophic and neuronal-plasticity research, while Selank is a tuftsin-related peptide studied in neurotransmitter, stress-response and neuroimmune models.
The scientific interest in this combination comes from the different research pathways represented by the two components, with dedicated functional-connectomic work examining both peptides' effects side by side (Learn more). Semax literature frequently examines BDNF, neuronal plasticity, learning and oxidative-stress responses; Selank literature includes GABAergic signalling, stress-related models and neuroimmune regulation, alongside related nootropic-research peptides such as [Semax] and [Selank] individually.
Compound-level reference data. Batch-specific results appear on the Certificate of Analysis.
Work out concentration with the peptide calculatorCrown Peptides Semax + Selank (Blend) is supplied for controlled laboratory research with batch-specific analytical documentation. High-Performance Liquid Chromatography (HPLC) can assess chromatographic purity, while Mass Spectrometry provides molecular information used to support identity verification. The batch-specific Certificate of Analysis is the definitive source for the exact purity result, identity data and analytical specification of the material supplied.
Researchers working with the Semax + Selank blend may also be interested in [Semax], [Selank], [DSIP], [VIP] and [Epitalon] — other neuro and signalling-research peptides studied in related research areas.
It is a research formulation combining Semax and Selank in a single 5mg/5mg vial.
Semax literature focuses heavily on neurotrophic and neuronal-plasticity pathways, while Selank is often studied in neurotransmitter, stress-response and neuroimmune models.
No. A two-peptide mixture is not represented by a single CAS number or molecular formula.
Use the product label and batch-specific Certificate of Analysis for the exact component ratio and analytical results.
Every batch is published openly — identity, purity and batch number, with no account needed.
Supplied for laboratory research purposes only — not for human consumption or for medical, veterinary or diagnostic use.
Each batch undergoes internal analytical verification using chromatographic and spectrometric methods prior to lyophilisation.
