Quickstart Highlights

Selank is a synthetic heptapeptide analog of tuftsin with demonstrated anxiolytic and anti-asthenic (energy-boosting) properties in human clinical trials[1][2]. In Russian studies, intranasal Selank produced anxiolytic effects comparable to benzodiazepines without sedation or dependence potential[1]. This educational protocol presents a once‑daily subcutaneous approach using practical dilution for accurate insulin‑syringe measurements.

  • Reconstitute: Add 3.0 mL bacteriostatic water (max vial capacity) → ~3.33 mg/mL concentration.
  • Typical daily range: 300–500 mcg once daily subcutaneously (gradual titration).
  • Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U‑100 insulin syringe.
  • Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Dosing & Reconstitution Guide

Standard / Gradual Approach (3 mL = ~3.33 mg/mL)

Week

Daily Dose

Units (per injection) (mL)

Weeks 1–2

300 mcg (0.3 mg)

9 units (0.09 mL)

Weeks 3–4

500 mcg (0.5 mg)

15 units (0.15 mL)

Frequency: Inject once daily subcutaneously[3]. A common cycling pattern is 4 weeks on, 4 weeks off to prevent tachyphylaxis, though continuous daily use has been studied in clinical trials for up to 14 days with good tolerability[2]. Some practitioners recommend administering 5 days per week with 2-day breaks[3].

For ≤10‑unit (≤0.10 mL) administrations, consider 30‑ or 50‑unit insulin syringes for improved readability.

Reconstitution Steps

  1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall; avoid foaming.
  3. Gently swirl/roll until dissolved (do not shake vigorously as peptides are delicate).
  4. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–16 week protocol with 4-week cycles and gradual titration.

  • Peptide Vials (Selank, 10 mg each):

     

    • 8 weeks (one 4-week cycle) ≈ 2 vials
    • 12 weeks (1.5 cycles) ≈ 4 vials
    • 16 weeks (two complete cycles) ≈ 5 vials
  • Insulin Syringes (U‑100):

     

    • Per week: 7 syringes (1/day)
    • 8 weeks: 56 syringes
    • 12 weeks: 84 syringes
    • 16 weeks: 112 syringes
  • Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.

     

    • 8 weeks (2 vials): 6 mL → 1 × 10 mL bottle
    • 12 weeks (4 vials): 12 mL → 2 × 10 mL bottles
    • 16 weeks (5 vials): 15 mL → 2 × 10 mL bottles
  • Alcohol Swabs: One for the vial stopper + one for the injection site each day.

     

    • Per week: 14 swabs (2/day)
    • 8 weeks: 112 swabs → recommend 2 × 100‑count boxes
    • 12 weeks: 168 swabs → recommend 2 × 100‑count boxes
    • 16 weeks: 224 swabs → recommend 3 × 100‑count boxes

Protocol Overview

Concise summary of the once‑daily anxiolytic/nootropic regimen.

  • Goal: Support reduction of anxiety and neurasthenia symptoms while providing anti-asthenic (energy-boosting) benefits[1][2].
  • Schedule: Daily subcutaneous injections for 4-week cycles with 4-week breaks (8–16 weeks total protocol).
  • Dose Range: 300–500 mcg daily with gradual titration.
  • Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for accurate unit measurements.
  • Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.

Dosing Protocol

Suggested daily titration approach.

  • Start: 300 mcg daily for weeks 1–2; clinicians treating cognitive or anxiety issues often begin at this level[3].
  • Target: 500 mcg daily by weeks 3–4 if lower doses are well-tolerated.
  • Frequency: Once per day (subcutaneous); some protocols use 5 days per week with 2-day breaks[3].
  • Cycle Pattern: 4 weeks on, 4 weeks off to prevent tachyphylaxis; repeat as needed.
  • Timing: Any consistent time; rotate injection sites to prevent irritation.

Storage Instructions

Proper storage preserves peptide quality.

  • Lyophilized: Store at −20 °C (−4 °F) for long-term stability (several months); refrigeration at 2–8 °C (35.6–46.4 °F) acceptable for shorter periods[10].
  • Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); stable for approximately 1 month with minimal potency loss[10]. Prepare aliquots if needed and avoid freeze–thaw cycles.
  • Allow vials to reach room temperature before opening to reduce condensation and moisture uptake.

Important Notes

Practical considerations for consistency and safety.

  • Use new sterile insulin syringes for each injection; dispose in a sharps container immediately after use[9].
  • Rotate injection sites (abdomen, thighs, upper arms) systematically to reduce local irritation and prevent tissue changes[7].
  • Inject slowly and steadily; wait a few seconds before withdrawing the needle.
  • Document daily dose, timing, and site rotation to maintain consistency throughout the protocol.
  • Multi-use bacteriostatic water vials should be dated upon opening and discarded within 28 days[9].

How This Works

Selank is a synthetic analog of the immunomodulatory peptide tuftsin, consisting of the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. In Russian clinical trials for anxiety disorders and neurasthenia, intranasal Selank produced anxiolytic effects comparable to benzodiazepines while also providing anti-asthenic (energy-boosting) benefits without sedative side effects or dependence potential[1][2]. Preclinical studies in primates demonstrated that intranasal Selank eliminated fear and anxiety behaviors with long-term stabilizing effects on neurobehavior[4]. Rodent studies confirmed robust anxiolytic efficacy comparable to classical tranquilizers[5]. While most published human data utilized intranasal dosing (the original formulation), subcutaneous administration has shown effectiveness in research settings with consistent absorption and ease of dose measurement[3]. A 14-day continuous course was well-tolerated and effective in human trials[2], and even high-dose applications have been explored for conditions such as attenuating opioid withdrawal symptoms in animal models[5].

Potential Benefits & Side Effects

Observations from clinical and preclinical literature.

  • Produces anxiolytic effects comparable to benzodiazepines in human clinical trials without sedation or dependence risk[1].
  • Provides anti-asthenic (energy-boosting) benefits alongside anxiety reduction[2].
  • Induces lasting neurobehavioral changes; primate studies showed elimination of fear/anxiety behaviors with long-term stabilizing effects[4].
  • Generally well tolerated in clinical studies; a 14-day continuous course was well-tolerated and effective in human trials[2].
  • Occasional mild injection-site reactions (redness, minor irritation) may occur with subcutaneous administration; proper site rotation minimizes this risk.
  • Lacks sedative side effects typical of classical anxiolytics, allowing for daytime use without impairment[1].
  • Has been explored at higher doses for experimental applications such as attenuating opioid withdrawal symptoms, indicating a wide therapeutic range[5].

Lifestyle Factors

Complementary strategies for optimal cognitive and anxiolytic outcomes.

  • Maintain consistent sleep hygiene and aim for 7–9 hours of quality sleep to support neurological function and stress resilience.
  • Incorporate regular physical activity; both aerobic exercise and resistance training support mood regulation and cognitive performance.
  • Practice stress-management techniques such as mindfulness, meditation, or breathwork to complement Selank’s anxiolytic effects.
  • Support nutritional status with adequate protein, omega-3 fatty acids, and micronutrients essential for neurotransmitter synthesis.
  • Minimize alcohol and stimulant use, which can interfere with anxiety management and neurological stability.

Injection Technique

General subcutaneous guidance from clinical best-practice resources[7][8].

  • Wash hands thoroughly and prepare a clean work surface.
  • Clean the vial stopper with an alcohol swab; allow to dry completely.
  • Draw the appropriate volume into a sterile insulin syringe; remove air bubbles by flicking the syringe and expelling air.
  • Clean the injection site with a fresh alcohol swab; allow skin to dry to prevent stinging.
  • Pinch a skinfold of subcutaneous tissue; insert the needle at 90° into the subcutaneous layer[7].
  • Do not aspirate for subcutaneous injections; inject slowly and steadily[8].
  • Withdraw the needle straight out after injection; apply gentle pressure if minor bleeding occurs.
  • Dispose of the used syringe immediately in an appropriate sharps container; never reuse needles or syringes[9].
  • Rotate sites systematically (abdomen at least 2 inches from navel, front/outer thighs, upper arms) to avoid lipohypertrophy[7].
