LPPEPTIDE | Selank 5mg | 5mg x 10 vials | 10 vials / box

What is SK5?

Selank is a synthetic heptapeptide based on the tuftsin sequence. Human studies have examined anxiety-related clinical measures, leu-enkephalin metabolism, EEG response patterns, and functional brain connectivity after Selank exposure. Intranasal drops or solution are the delivery methods reported in the primary human research summarized on this page. The vial calculation is concentration based. Dividing 5,000 mcg by the measured final volume gives mcg per mL. Multiplying that concentration by the verified pump output gives mcg per spray.

Research context

5 mL option: 1,000 mcg/mL and 100 mcg per verified 0.10 mL spray. 10 mL option: 500 mcg/mL and 50 mcg per verified 0.10 mL spray. Final-volume rule: Bring the transferred solution to an exact measured final volume.

Reference literature focus

Selank is a synthetic heptapeptide based on the tuftsin sequence. Human Selank research has primarily used the intranasal route. Quick reference for the intranasal Selank 5 mg calculation. Human research route: Intranasal drops or solution. Peptide amount: 5,000 mcg total in the vial. 5 mL option: 1,000 mcg/mL and 100 mcg per verified 0.10 mL spray. 10 mL option: 500 mcg/mL and 50 mcg per verified 0.10 mL spray. Final-volume rule: Bring the transferred solution to an exact measured final volume.

LPPeptide handling reference

Human research route: Intranasal drops or solution. Peptide amount: 5,000 mcg total in the vial. 5 mL option: 1,000 mcg/mL and 100 mcg per verified 0.10 mL spray. 10 mL option: 500 mcg/mL and 50 mcg per verified 0.10 mL spray. Final-volume rule: Bring the transferred solution to an exact measured final volume.

Storage

Registered 0.15% product: Protected from light, stored at no more than 10 degrees C, and not frozen. Opened registered product: The manufacturer permits storage at no more than 25 degrees C for up to 15 days. Custom research preparation: Use formulation-specific stability and microbiological controls rather than transferring the finished-product shelf life. Labeling: Record preparation date, final volume, concentration, vehicle, and storage condition

Safety observations

The 2008 comparative study reported similar anxiety-related effects for Selank and medazepam, with additional anti-asthenic and psychostimulant observations in the Selank group. In the 2012 GAD study, 40% of participants were classified as rapid responders during days 1 to 3, while 60% showed a gradual response pattern through day 14. The healthy-volunteer neuroimaging study examined functional connectivity after one intranasal Selank exposure rather than a repeated clinical course. The current manufacturer instruction lists unpleasant taste sensations and possible allergic reactions among reported adverse effects. Pump output, formulation, nasal condition, and administration technique can affect the delivered amount and deposition pattern.

Important Notes

Small measurement and device details can materially change the amount delivered per spray. Use a measured final volume, not the bottle capacity mark alone. Verify that the actuator releases 0.10 mL per full stroke before applying the main table. Prime and reprime exactly as specified for the pump, then record those actuations. Keep the bottle upright and use a complete, consistent stroke for each recorded spray. Treat the theoretical 50 or 100 sprays as nominal counts because priming and residual hold-up consume part of the volume. A 5 mg vial contains 5,000 mcg total. Calculate the complete peptide requirement before modeling any multi-day published protocol. Use a validated laboratory handling and stability plan for any custom multidose preparation.
