Peptides for Sleep and Mood
Think Clearer. Sleep Deeper. Feel Like Yourself Again.
Brain, Sleep & Mood Peptide Therapy at Nava Health — clinically supervised neuropeptide protocols that address the root cause of mental fog, poor sleep, and emotional imbalance.


What Is Brain, Sleep & Mood Peptide Therapy?
Mental clarity, good sleep, and emotional stability are not three separate problems. They’re connected — driven by the same underlying biology. Neurotransmitter levels. Hormone balance. Inflammation. Cortisol patterns. When one goes off, the others tend to follow.
That’s why treating them one at a time rarely works. A sleep medication doesn’t fix the anxiety causing the sleep problem. An antidepressant doesn’t address the gut inflammation driving the mood symptoms. A stimulant doesn’t fix why focus is hard in the first place.
Brain, Sleep & Mood Peptide Therapy works on these interconnected systems — calming overactive stress responses, restoring the deep sleep that the brain needs to actually repair, reducing neuroinflammation that clouds thinking, and rebalancing the internal environment that governs how you feel day to day.
At Nava Health, every protocol starts with your labs. We look at cortisol patterns, thyroid function, neurotransmitter markers, and inflammatory biomarkers before recommending anything. Because the cause matters as much as the symptom.
Our Brain, Sleep & Mood Peptides
Each peptide below targets a different part of neurological and emotional function.
Your Nava provider will recommend the right one based on your labs and what you’re experiencing.
Semax + Selank
“The Calm Brain Fuel”
What It Targets
Difficulty focusing, persistent anxiety, and mental overwhelm — the exhausting combination of not being able to think clearly while simultaneously not being able to wind down.
How It Works
Semax and Selank are two neuropeptides that work well together. Semax increases BDNF — Brain-Derived Neurotrophic Factor — which supports cognitive function, neuroplasticity, and mental sharpness. Selank works on GABA and serotonin pathways to reduce anxiety and emotional reactivity, without sedation. One sharpens the mind. The other calms the nervous system. Together, they address both sides of the problem.
The Result
Mental clarity that doesn’t come at the expense of calm. Focus that isn’t fueled by anxiety. The ability to think well and feel settled at the same time.
Best For
Brain fog, difficulty focusing, anxiety, mental overwhelm, stress-driven cognitive fatigue, cognitive performance
DSIP
“The Deep Rest Anchor”
What It Targets
Years of poor, non-refreshing sleep — where hours in bed don’t translate to actual recovery and waking up tired has just become expected.
How It Works
DSIP — Delta Sleep-Inducing Peptide — is naturally produced in the brain and plays a direct role in sleep architecture. Specifically, it promotes delta sleep, the deepest stage where growth hormone is released, memory gets consolidated, and real cellular repair happens. It works with the brain’s own sleep mechanisms, not against them. No sedation, no suppression of REM, no morning grogginess.
The Result
Actually reaching the deepest levels of sleep consistently. Waking up feeling restored instead of just less tired.
Best For
Poor sleep quality, non-restorative sleep, difficulty reaching deep sleep, waking tired despite enough hours
VIP
“The Internal Balancer”
What It Targets
Brain fog and a broad range of cognitive and mood symptoms — particularly in people whose issues trace back to environmental toxins, mold exposure, or widespread biochemical imbalance.
How It Works
VIP — Vasoactive Intestinal Peptide — is a neuropeptide with regulatory effects across multiple systems. It modulates the immune response, supports neurotransmitter balance, helps regulate circadian rhythms, and improves vascular function in the brain. For people dealing with biotoxin illness or mold-related cognitive symptoms, VIP addresses the neuroinflammatory environment that drives the brain fog, mood disruption, and sleep dysregulation that come with it.
The Result
Clearer thinking. Better emotional stability. A more balanced internal environment — especially valuable for people whose symptoms haven’t improved with conventional approaches.
Best For
Brain fog linked to mold or toxin exposure, neuroinflammation, mood imbalance, circadian disruption, cognitive impairment

Have More Questions?
Will these make me feel sedated or foggy?
No. Semax and Selank produce calm focus — not sedation. DSIP supports deeper sleep without residual grogginess. The goal with all of these is a clearer, calmer, better-rested version of you. Not a numbed-down one.
How soon will I notice changes in sleep and mood?
Many people report noticeable shifts in sleep quality and emotional steadiness within the first two to four weeks. Deeper cognitive improvements tend to become more apparent at six to eight weeks of consistent use.
Can these help with anxiety without going on medication?
Selank specifically has shown anxiolytic effects through GABA and serotonin modulation — without the dependence risk of benzodiazepines or the side effect profile of SSRIs. All protocols are evaluated individually and medically supervised.
Can these be combined with other Nava treatments?
Yes. Brain and mood peptides are frequently paired with hormone optimization, NAD+ IV therapy, and cortisol management protocols for a more comprehensive approach.
