Selank

Selank is a synthetic anxiolytic nootropic peptide studied for stress resilience, cognition, and mood support, with the source summarizing a low-friction once-daily subcutaneous version of a commonly discussed protocol.

Profile · 01

Overview

Selank is a synthetic peptide discussed primarily for anxiolytic, cognitive-support, and anti-asthenic effects. It is often compared with Semax in nootropic-peptide conversations, but the source positions Selank more strongly around calm focus and stress resilience.

This page follows the source's once-daily subcutaneous protocol. Many real-world discussions also include intranasal use, but the site page here stays faithful to the provided markdown source.

Protocol

Simple once-daily titration approach using a four-week on, four-week off rhythm.

Reconstitute
Add 3.0 mL bacteriostatic water to a 5 mg vial for about 1.67 mg/mL concentration
Typical daily range
300-500 mcg once daily
Start
300 mcg daily for Weeks 1-2
Target
500 mcg daily by Weeks 3-4
Frequency
Once daily (subcutaneous)
Cycle Length
4 weeks on, 4 weeks off; repeat as needed
Timing
Any consistent time; rotate injection sites
Route
Subcutaneous
Cycle
4 weeks on, 4 weeks off

Inject once daily subcutaneously using a straightforward two-step titration. The source presents Selank as a relatively gentle peptide focused on calm cognition and stress resilience rather than stimulation.

Dose progression

Weeks 1-2
300 mcg (0.3 mg) · 18 units (0.18 mL)
Weeks 3-4
500 mcg (0.5 mg) · 30 units (0.30 mL)

Science · 01

How Selank works.

Selank is commonly described as an anxiolytic peptide with effects on stress response, attention, and cognition. The source positions it as useful where calm focus is the goal rather than aggressive stimulation.

Compared with more experimental entries, Selank has a relatively established peptide-community profile, though rigorous route-specific human data remain limited.

Science · 02

Effects

Observations from clinical or preclinical literature.

May support reduced anxiety and improved stress resilience
Often discussed for calm focus and cognitive support
Straightforward low-volume dosing makes the protocol easy to follow
Human route-specific efficacy data remain limited
Mild injection-site irritation may occur
Science · 03

Caution

Not recommended during pregnancy or breastfeeding because safety data is insufficient
Use caution with other CNS-active agents if sensitivity is a concern
Do not assume all nootropic effects are universally positive or consistent

CoFactors

Magnesium glycinate
Commonly paired with relaxation and stress-resilience goals.
L-theanine
Often discussed alongside calm-focus protocols.
Sleep hygiene
Foundational for cognitive and anxiolytic outcomes.
Lifestyle · 02

Life Factors

Complementary strategies for best outcomes.

Pair with stress-management practices such as breathwork, therapy, or meditation
Maintain consistent sleep and caffeine discipline
Use exercise and a nutrient-dense diet to reinforce mood and cognition goals
Track response during both the on-cycle and off-cycle for perspective
Lifestyle · 03

Metrics

Day-to-day metrics worth tracking through the protocol.

  1. Stress and anxiety levels - useful subjective trend markers
  2. Focus and cognitive clarity - helpful for nootropic-response tracking
  3. Sleep quality - an important companion variable
  4. Injection-site reactions - note redness, swelling, or discomfort
Lifestyle · 04

Labs

Baseline and periodic bloodwork to monitor systemic health during the protocol.

CBC (Complete Blood Count)
General baseline and follow-up monitoring.
CMP (Comprehensive Metabolic Panel)
Assesses liver and kidney function during the protocol.
Vitamin D, B12, folate
Useful baseline cofactors for mood and cognitive context.

Preparation

Careful technique preserves potency. Solution should be clear — do not shake.

  1. Allow vial to reach room temperature for 15–20 minutes before reconstitution.
  2. Draw the chosen bacteriostatic water volume with a sterile syringe.
  3. Inject slowly down vial wall; avoid foaming.
  4. Gently swirl/roll until dissolved (do not shake).
  5. Label with reconstitution date and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
  6. Use within 30 days; discard any unused solution after 30 days.

Technique

General subcutaneous guidance from clinical best-practice resources.

Clean the vial stopper and injection site with alcohol and allow them to dry fully
Pinch a skinfold and insert the needle at 45-90 degrees into subcutaneous tissue
Do not aspirate for subcutaneous injections; inject slowly and steadily
Rotate sites across the abdomen, thighs, and upper arms
Discard used syringes immediately in a sharps container

Storage

Lyophilized
Store at room temp in dry, dark conditions; minimize moisture exposure.
Reconstituted
Refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles. Discard reconstituted vials after 30 days.

Notes

Allow vials to reach room temperature before opening to reduce condensation uptake.
