Selank — Dosing, Cycles, Half-Life & Side Effects
Selank is a nootropic peptide with a half-life of Minutes (rapid degradation). Synthetic analog of tuftsin with anxiolytic and nootropic properties. Developed in Russia and approved there for anxiety and neurasthenia. Increases BDNF and modulates monoamine neurotransmitters.

Typical Dosing Ranges
Common dose range: 250-500mcg intranasal or subcutaneous daily
Cycle length: 4-8 weeks
Dose ranges are compiled from published pharmacokinetic studies and community-reported usage. Where a value is community-reported rather than clinically studied, this page and its structured data flag it. Lower end of any range is always the safer starting point.
Stacking Considerations
- No structural stacking blockers. Standard harm-reduction rules apply: minimize total androgen load, minimize oral exposure, and monitor bloodwork.
PCT Requirements
- Never stack two SERMs. Extend a single SERM (tamoxifen OR enclomiphene/clomiphene) rather than combining.
- Use the cycle planner to generate a full protocol based on your complete stack, not this compound alone.
Side Effect Profile
- Very short half-life
- Limited Western clinical trials
- Requires intranasal or injection
- Effects are subtle
- Not FDA approved
Known Interactions

Monitoring (Bloodwork & Vitals)
- Comprehensive metabolic panel (baseline, mid-cycle, post-cycle)
- Lipid panel (total cholesterol, HDL, LDL, triglycerides)
- CBC (hemoglobin, hematocrit — watch for erythrocytosis)
- Sex-hormone panel (Total T, Free T, Estradiol sensitive, SHBG, LH, FSH)
- Blood pressure (weekly self-check; flag systolic >140 or diastolic >90)
Baseline bloodwork is recommended before any cycle. Discontinue if liver enzymes exceed 3× upper limit of normal or if hematocrit exceeds 54%.
Frequently Asked Questions
What is the half-life of Selank?
Selank has a half-life of approximately Minutes (rapid degradation). This figure is used to determine injection frequency (for esters) and post-cycle clearance timing.
What is the typical dose range for Selank?

Selank causes minimal suppression of the HPTA axis (score 0/10). PCT may still be advisable depending on stack and duration.
What is Selank typically used for?
Selank is commonly used for: Anxiety reduction, Cognitive enhancement, Stress adaptation, Focus improvement. Intended-use context does not imply safety — every use case carries the same underlying pharmacological risks.
Is Selank legal?
