Adalank
N-Acetyl Selank Amidate | Enhanced Tuftsin Analog
On this page
What is Adalank?
Adalank (N-Acetyl Selank Amidate) is a lab-modified version of Selank, a short synthetic peptide originally derived from tuftsin, engineered with extra chemical groups meant to help it stay stable and cross into the brain more easily. Researchers study the Selank family for its effects on GABA and BDNF-related pathways in anxiety and cognition research, most of it from animal models and the shorter research history of Selank itself. It's sold here strictly as a research chemical for laboratory study, not for use in people or animals.
Key terms:
Adalank is a synthetic modified heptapeptide (enhanced tuftsin analog).
Adalank (N-Acetyl Selank Amidate) is a lab-made version of the peptide Selank. Chemists added groups to both ends: acetylation at one end, amidation at the other. Those changes make it more stable and help it cross the blood-brain barrier (the filter that protects the brain). Selank itself came from tuftsin, a natural immune-signaling peptide. Researchers study Adalank for anxiety reduction, cognitive effects, nerve protection, and stress resilience, and report it stays active longer than Selank does.
Key research areas
- Potent anxiolytic effects
- Enhanced cognitive function
- Stress resilience
- Improved mood and emotional stability
- Neuroprotection
- Immunomodulatory support
- Reported improved bioavailability and extended half-life compared to parent compound Selank
Researched dosing
This table shows how researchers have structured study dosing schedules for Adalank — published research methodology, not personal usage instructions.
| Phase | Dose | Frequency | Route |
|---|---|---|---|
| Anxiety models | 200-300mcg | 1x daily (morning) | SubQ |
| Cognitive-performance studies | 200-500mcg | 1x daily | SubQ |
| Stress-response studies | 200-300mcg | 2x daily (morning, afternoon) | SubQ |
| Initial assessment | 100-200mcg | 1x daily | SubQ |
Commonly cycled 4 weeks on, 1+ weeks off.
How it works
At the cell level, Adalank research builds on Selank studies of how the peptide crosses into brain tissue and interacts with GABA signaling and BDNF levels — the chemical modifications in Adalank are designed to make that crossing more efficient than the parent compound.
Adalank crosses the blood-brain barrier via enhanced lipophilicity from N-acetylation and C-terminal amidation. It modulates GABAergic neurotransmission, upregulates BDNF in the hippocampus, influences serotonin metabolism, provides immunomodulatory effects via tuftsin-derived mechanisms, and reduces stress-related neurotransmitters without benzodiazepine dependency.

Research applications
This section lists the body systems and research areas scientists have studied for Adalank and its parent compound Selank — a summary of what's been investigated in the literature, not medical claims about people.
Anxiety
Parent compound Selank demonstrated anxiolytic effects comparable to benzodiazepines in clinical trials with 62 GAD patients, with 40% showing rapid response within 1-3 days. N-Acetyl modification enhances these effects. Research shows Selank reduces stress-induced anxiety through modulation of stress hormones and neurotransmitter balance, with enhanced stability in N-Acetyl form prolonging anxiolytic benefits. Unlike benzodiazepines, provides anxiety relief without sedation, amnesia, tolerance, withdrawal, or dependency.
Cognitive
Cognitive enhancement through BDNF upregulation, improved focus and memory formation via hippocampal neuroplasticity mechanisms.
Neuroprotective
Neuroprotective effects through BDNF-mediated pathways and anti-inflammatory mechanisms derived from tuftsin analog activity.

Interactions
This list shows which other nootropic and anxiety-research peptides scientists study alongside Adalank, and includes a note on the parent compound's studied interaction with a benzodiazepine in animal research.
Reconstitution & storage
This is the standard laboratory method for turning freeze-dried Adalank powder into a liquid research solution — the same basic water-based mixing process used for most peptide research.
- Clean work area and hands thoroughly with alcohol
- Calculate required BAC water volume using calculator below
- Draw calculated BAC water into syringe
- Inject slowly down vial side (not directly onto powder)
- Gently swirl until completely dissolved (never shake vigorously)
- Store the reconstituted solution refrigerated (2–8°C), labeled with the date and concentration, for laboratory research use only.
Lyophilized: Cool, dry place (room temperature), use within Per manufacturer expiration date
Reconstituted: 2-6°C, use within 14-30 days

These are the visual and lab-report checks researchers use to confirm an Adalank sample is pure and correctly identified before it goes into a study.
White, Fluffy Powder - Lyophilized Adalank should appear as white to off-white, fluffy powder filling the vial bottom. Indicates proper freeze-drying and storage.
Clear Solution After Reconstitution - When properly mixed with BAC water, solution should be crystal clear with no particles, cloudiness, or discoloration.
Proper Labeling - Vial should have clear labeling with peptide name (Adalank or N-Acetyl Selank Amidate), batch number, manufacturing date, and storage instructions from reputable research supplier.
Slight Compaction - Minor compaction from shipping is acceptable if powder dissolves completely with gentle swirling. Should not remain permanently clumped.
Discoloration or Yellowing - Any yellow, brown, or unusual coloration indicates oxidation, degradation, or improper storage. Adalank should be white to off-white only.
Cloudy After Reconstitution - Persistent cloudiness, particles, or precipitates after gentle mixing indicate degraded, contaminated, or improperly manufactured peptide.

This section covers handling cautions and regulatory notes for Adalank in a laboratory setting — it flags that direct human research on this specific modified form is limited, and that the parent compound's regulatory approval is outside North America.
- Not recommended during pregnancy or breastfeeding due to lack of safety data
- Consult healthcare provider before use, especially with other psychiatric medications
- Not FDA-approved; approved for clinical use in Russia since early 2000s
- CRITICAL: This is an experimental peptide with limited direct human research data on N-Acetyl form
Regulatory status
- Not approved by the FDA for any indication.
- Supplied and described for laboratory research use only — not for human or veterinary use.
