- The quantity of visible material may appear small relative to vial size
- Visual appearance alone does not establish identity or purity
03Storage & laboratory handling
Storage requirements may vary by compound, formulation and production lot. Refer to the product label and available product-specific documentation.
- Protect research materials from excessive heat
- Limit unnecessary exposure to direct light and moisture
- Keep containers securely closed when stored
- Follow product-specific temperature requirements when provided
- Use appropriate laboratory contamination-control procedures
04Packaging & quality documentation
Packaging components may vary slightly between production lots. This can include vial closures, cap styles, label positioning and external packaging.
- Check the product label and lot identifier before laboratory use
- Inspect the vial and closure for visible shipping damage
- Packaging design may differ between batches
- Lot-specific analytical documentation may be available in our COA library

01
Blend Profile
Selank + Semax Research Material
The Selank + Semax 20 mg blend is a defined two-component research formulation containing equal quantities of two structurally distinct synthetic heptapeptides.
Selank is structurally related to the tuftsin peptide sequence, while Semax is structurally associated with an ACTH-derived peptide fragment. Both contain seven amino-acid residues but maintain separate molecular identities within the blend.
Royal Peptides supplies this formulation exclusively as a laboratory research material for controlled analytical and experimental investigation.
02
Defined Composition
10 mg Selank + 10 mg Semax
The 20 mg vial contains a defined 1:1 composition by labeled peptide mass, providing equal quantities of Selank and Semax within a single research formulation.
Component 01
Selank
10 mg
Synthetic heptapeptide structurally derived from a tuftsin-related peptide sequence.

Selank Component
Selank provides one defined seven-residue peptide sequence within the formulation and retains its individual compound identity for analytical research.
Semax Component
Semax provides a separate seven-residue peptide sequence within the formulation and remains analytically distinct from Selank.
Shared PGP Terminus
Both peptide sequences contain a Pro-Gly-Pro sequence at their C-terminal region, providing a useful structural feature for comparative laboratory investigation.
Defined 1:1 Composition
Equal labeled quantities provide a controlled dual-component material for experiments requiring a predefined Selank-to-Semax ratio.
04
Scientific Context
Controlled Multi-Component Research
Selank and Semax have individually appeared in experimental literature involving peptide-associated molecular and neurobiological systems. A blended material can support controlled research designs where both defined peptide components are evaluated within the same experimental system.
Comparative Peptide Research
Researchers may investigate structural or analytical similarities and differences between the two defined heptapeptide components.
Molecular Signaling Models
Controlled experimental systems may examine measurable molecular variables associated with peptide signaling pathways.
Multi-Component Analysis
The formulation provides a defined dual-component material for analytical methods designed to distinguish or quantify multiple peptide constituents.
Structure-Function Research
The distinct parent sequences together with their shared Pro-Gly-Pro terminal motif provide structural variables for controlled comparative investigation.
05
Analytical Documentation
Batch-Specific Research Information
Laboratory evaluation should rely on analytical documentation corresponding to the specific production lot received. For a multi-component formulation, researchers should distinguish between total labeled material quantity and the identity or measured content of each individual peptide component.
