Common mistakes with Selank
Avoid the most common pitfalls when working with Selank in a research setting: storage, reconstitution, concentration, and COA verification mistakes.
Mistake 1: Improper storage after reconstitution
Once Selank is reconstituted with bacteriostatic water, it must be stored at 2-8°C (refrigerated) and used within 28 days. A common mistake is leaving the vial at room temperature for extended periods, which degrades the peptide and can invalidate experimental results.
Freeze-thaw cycles are another issue — each cycle reduces peptide integrity. If your protocol requires long-term storage, keep the lyophilised vial frozen at -20°C until the moment of reconstitution.
Mistake 2: Concentration miscalculation
Calculating the target concentration wrong is one of the most common experimental errors with Selank. Always double-check:
- The stated vial mass (e.g. 5mg, 10mg)
- The volume of bacteriostatic water added
- The resulting concentration (mass / volume)
- The volume of reconstituted solution you draw into the syringe for each dose point
A simple spreadsheet or lab notebook with these values at the top of every experiment can prevent costly errors.
Mistake 3: Skipping COA verification
Researchers sometimes trust a supplier's purity claim without checking the actual COA. For Selank, always:
- Match the batch number on your vial to the COA on the product page
- Verify the HPLC chromatogram shows a single clean peak
- Confirm the mass spectrometry reading matches the theoretical molecular weight
- Check the expiry date
Skipping this step means you are treating purity as a marketing claim rather than a verifiable fact. Peptify publishes every batch COA at peptifyuk.com, downloadable directly from each product page.

Frequently asked questions
What makes Selank different from benzodiazepines?
Selank has shown anxiolytic effects comparable to benzodiazepines in preclinical studies but without sedation, tolerance development, or withdrawal symptoms.
Does Selank affect the immune system?
Yes. Selank has immunomodulatory properties including enhancement of IL-10 production and stabilisation of blood cytokine levels.
