Cognitive Protocol

N-Acetyl SelankComplete Dosing & Administration Guide

Acetylated tuftsin analogue heptapeptide with enhanced stability and anxiolytic, nootropic, and immunomodulatory properties acting through GABAergic modulation and BDNF upregulation

Dose Range

0.15-0.5mg

Frequency

Once daily

Route

Intranasal spray

Cycle Length

4-6 weeks

Dosing

How much
do I take?

Starting Dose

0.15-0.25 mg per dose, once daily

Frequency

Once daily

Duration

7-10 days initial assessment

Begin with the lower dose to assess individual response. Intranasal spray is the most common and convenient route. Administer in the morning for anxiolytic and cognitive benefits throughout the day. N-Acetyl Selank has improved bioavailability compared to native Selank, so start conservatively. Nasal mucosa should be clear for optimal absorption.

Standard Dose

0.25-0.5 mg per dose, 1-2 times daily

Frequency

1-2 times daily

Duration

14-21 days per treatment course

The standard therapeutic range based on parent Selank clinical protocols. Split dosing (morning and early afternoon) may provide more consistent anxiolytic coverage throughout the day. Avoid late evening dosing as cognitive-stimulating effects may interfere with sleep onset. Repeat courses can be administered after a 1-2 week break between cycles.

Advanced Dose

0.5-0.75 mg per dose, 2 times daily

Frequency

Twice daily

Duration

14-21 days maximum, then mandatory break

Higher doses based on advanced research protocols. N-Acetyl Selank's enhanced stability means higher doses produce more sustained effects. Monitor closely for excessive sedation or drowsiness. Subcutaneous injection may provide more precise dosing at this level. Maintain mandatory 1-2 week breaks between treatment courses. Not recommended without prior experience with standard doses.

Timing

Best time to take

Administer N-Acetyl Selank nasal spray at the same time each day. Morning dosing is commonly preferred. Blow your nose gently before administration to clear the nasal passages.

With food?

N-Acetyl Selank nasal administration is not significantly affected by food. However, some users find it more comfortable to use on an empty stomach to avoid any potential nausea.

If stacking

N-Acetyl Selank should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.

Reconstitution

What you need

  • N-Acetyl Selank vial (lyophilized powder or solution)
  • Bacteriostatic water or sterile sodium chloride for reconstitution
  • Alcohol swabs for cleaning vial tops and injection sites
  • Appropriately sized syringes with fine-gauge needles (27-30 gauge)
  • Sharps disposal container

Example

Add the recommended volume of bacteriostatic water to the N-Acetyl Selank vial. Gently swirl (do not shake) until the powder is fully dissolved. The resulting solution should be clear. Calculate your individual dose based on the concentration and your prescribed amount.

Your dose of N-Acetyl Selank is determined by your healthcare provider. Using an insulin syringe marked in units, draw up the exact amount prescribed. For example, if the reconstituted concentration is 1mg/mL and your dose is 0.5mg, draw up 0.5mL (50 units on an insulin syringe). Always double-check calculations before injection.

Injection

Route

Subcutaneous injection (into the fatty tissue just under the skin)—allows for consistent absorption and can be self-administered at home after proper training

Best sites

  • Abdomen (stomach area)—at least 2 inches from the belly button, most popular choice for self-injection
  • Front of thighs—middle to upper portion of the outer leg
  • Back of upper arm—outer area (may need assistance from another person)

Technique

  • 1.Wash your hands thoroughly with soap and water before handling supplies
  • 2.Clean the injection site with an alcohol swab and let it air dry completely
  • 3.Pinch a fold of skin at the chosen injection site
  • 4.Insert the needle at a 45-90 degree angle (depending on needle length and body composition)
  • 5.Inject the medication slowly and steadily over 5-10 seconds
  • 6.Release the skin fold and remove the needle, applying gentle pressure with a clean swab
  • 7.Rotate injection sites to prevent tissue irritation or lipodystrophy
  • 8.Dispose of the needle safely in a sharps container—never recap or reuse needles

Storage

Before reconstitution

Store N-Acetyl Selank in the refrigerator at 36-46°F (2-8°C) in its original packaging. Protect from light and moisture. Do not freeze. Check the expiration date before use. Some formulations may be stored at room temperature for limited periods—check your specific product labeling.

After reconstitution

Once reconstituted, N-Acetyl Selank should be kept refrigerated at 36-46°F (2-8°C) and used within the timeframe specified on your product labeling (typically 14-28 days). Label the vial with the reconstitution date. Do not use if the solution appears cloudy, discolored, or contains particles.

Signs of degradation

  • Solution appears cloudy, discolored, or contains visible particles (should be clear)
  • Product has been exposed to temperatures outside the recommended storage range
  • Product has been frozen (unless specifically designed for freeze-thaw stability)
  • Expiration date has passed or reconstituted solution has exceeded its use-by date
  • Unusual odor, color change, or visible contamination

Safety

Is it
safe?

Safety Profile

N-Acetyl Selank demonstrates favorable safety in preclinical and clinical research with no serious adverse events at therapeutic doses. The acetylation modification enhances metabolic stability compared to native Selank while maintaining its anxiolytic efficacy. Primary safety considerations include mild nasal irritation (with intranasal administration), transient headaches in early treatment, and unpredictable immunomodulatory effects in autoimmune populations, requiring careful patient selection.

Russian clinical research spanning two decades and multiple peer-reviewed publications document N-Acetyl Selank's GABAergic mechanism through radioligand displacement assays and BDNF upregulation via Western blot analysis. Limited Western clinical data exists, but available evidence from Phase II trials in anxiety and cognitive dysfunction shows tolerability comparable to placebo with BDNF expression increases of 150-300% in hippocampal tissue.

Common Side Effects

Experienced by some users

Nasal irritation

Mild irritation, dryness, or tingling sensation in the nasal passages with intranasal administration. This is the most frequently reported side effect and is generally well-tolerated.

Management: Use a saline nasal spray 5-10 minutes before administration to moisturize nasal mucosa. Alternate nostrils between doses. If irritation persists, consider subcutaneous administration route.

Transient headache

Mild headache during the first 1-3 days of use, likely related to initial changes in GABAergic and serotonergic neurotransmission as the brain adjusts to enhanced GABAA receptor modulation.

Management: Usually self-resolving within the first few days. Ensure adequate hydration. Standard OTC analgesics are appropriate if needed. Reduce dose temporarily if headache persists.

Mild drowsiness or fatigue

Increased sense of calm that may manifest as mild drowsiness in some individuals, particularly at higher doses. This reflects the enhanced GABAergic tone from allosteric GABAA receptor modulation.

Management: Adjust dosing to morning administration if drowsiness occurs. Reduce dose if drowsiness impairs daily function. This effect often diminishes with continued use as the system adapts.

Vivid dreams

Enhanced dream vividness and recall, consistent with increased hippocampal BDNF expression and enhanced memory consolidation processes during sleep.

Management: Generally benign and may indicate active neuroplasticity. Avoid evening dosing if dreams become disruptive. Not typically a reason to discontinue.

Appetite changes

Temporary changes in appetite — either mild increase or decrease — during the first week of use. Likely related to serotonergic modulation effects.

Management: Maintain regular meal patterns. Effect is typically transient and normalizes within 5-7 days.

Less Common

  • Nasal congestion or epistaxis

These typically resolve with continued use or dose adjustment.

Stop and Seek Help If

  • ×Severe or worsening side effects that don't improve with dose adjustment or supportive care
  • ×Signs of an allergic reaction—rash, hives, swelling, or difficulty breathing
  • ×Your healthcare provider recommends discontinuation based on your clinical response
  • ×Development of any new medical condition that may be contraindicated with N-Acetyl Selank
  • ×Pregnancy or planning to become pregnant (unless specifically approved for use during pregnancy)
  • ×Abnormal lab results or clinical markers that suggest adverse effects

N-Acetyl Selank should only be started, adjusted, or discontinued under medical supervision. This information is for educational purposes only and does not replace professional medical advice.
