Semax + Selank

Semax & Selank Blend (5mg + 5mg / 10mg + 10mg)

The Semax & Selank combination is a synergistic neuropeptide blend designed to support cognitive function, emotional balance, and overall brain health.

By combining two well-studied neuroactive peptides, this formulation enhances memory, focus, and stress resilience while supporting long-term neurological function.

Unlike traditional compounds, Semax and Selank act directly on the central nervous system, modulating neurotransmitters and promoting neuroprotective activity.

Mechanism of Action

Semax is a synthetic peptide derived from ACTH fragments that enhances BDNF expression and supports neuronal signaling, improving cognitive performance and mental clarity.

Selank is a regulatory peptide that modulates GABAergic activity, helping to reduce anxiety and stabilize mood without sedation.

Together, they provide:

• enhanced cognitive processing

• improved stress resilience

• balanced neurotransmitter activity

Form & Stability

All Peptide Labs peptides are produced with 99%+ purity and are lyophilized to preserve potency and stability.

Unmixed (Freeze-Dried):

Stable for up to 1 year in the refrigerator (2–8 °C / 36–46 °F) and over 5 years in the freezer (-20 °C / -4 °F).

After Reconstitution:

Store in the refrigerator (2–8 °C / 36–46 °F) and use within 30 days for optimal results.
