Semax & Selank

Semax is studied for its effects on focus, motivation, and mental clarity. Research suggests it supports brain plasticity and the systems involved in attention and decision-making — helping your brain adapt as you work toward healthier habits, rather than acting as a shortcut.

Selank is studied for its calming effects on stress and anxiety. By supporting healthier stress regulation, it may make it easier to stay level-headed under pressure — a key piece of building habits that last.

Description Semax & Selank

Exciting Research Findings:

Reduced Anxiousness Published in 2020, this human resting-state fMRI study in 52 healthy participants showed that Selank injection rapidly altered functional connectivity in anxiety-related brain regions (amygdala) and executive function areas (dorsolateral prefrontal cortex), with effects observed 5-20 minutes post-injection, supporting its quick-onset anxiolytic mechanism. Improved Stress Response Published in 2020, this preclinical study in rats demonstrated that daily intraperitoneal Selank (100 mcg/kg) over 20 days under social stress significantly reduced pro-inflammatory cytokines (IL-1B, IL-6, TNF-α, TGF-β1) to near-control levels, indicating strong anti-inflammatory and stress-protective effects. Reduced Withdrawal-Related Anxiety Published in 2022, this rat study found that a single intraperitoneal injection of Selank (0.3 mg/kg) reduced morphine withdrawal symptoms by ~40% (e.g., convulsions, ptosis, allodynia), comparable to diazepam but with a distinct profile, highlighting its potential in managing withdrawal-related anxiety.

About Semax & Selank

When the peptide Selank is injected, the GABA receptors are stimulated, promoting relaxation and calmness while reducing tension and restlessness. Selank has been shown to enhance cognitive function, reduce anxiety and stress, improve mood and sleep, and boost the immune response.

Protocol Components

Dual Molecular Synergy
Semax

COGNITION

Semax is a synthetic peptide known for its neuroprotective and cognitive-enhancing properties. Originally developed for treating stroke and cognitive disorders, research indicates its potential in modulating brain-derived neurotrophic factor (BDNF).

Primary Physiological Targets
  • Enhances cognitive function and memory consolidation.
  • Promotes neurogenesis and protects neurons.
  • Improves attention and focus in research models.

Selank

RELAXATION

Selank is a synthetic analog of the naturally occurring peptide tuftsin. It is extensively researched for its anxiolytic (anti-anxiety) effects and its ability to modulate the expression of Interleukin-6 and GABA receptors, promoting a state of calm focus.

Primary Physiological Targets
  • Modulates anxiety and stress responses.
  • Influences GABAergic neurotransmission.
  • Stabilizes mood without sedative side effects.
