Selank Dosage Chart: Typical Doses for Nasal Spray and Injection Use

There is no FDA-approved selank dosage, and the amounts used in research are not standardized. Most published and vendor protocols settle between 250 mcg and 500 mcg per dose, taken one to three times per day, with total daily exposure usually staying under 1.5 mg. Selank is a synthetic tuftsin analog sold as a research chemical, so any figure in a selank dosage chart should be treated as a research reference point rather than a clinical prescription.

Selank Dosage Chart: Common Research Protocols

The table below summarizes the ranges that appear most often in Russian clinical literature, vendor instruction sheets, and online research logs. Values are listed in micrograms (mcg) because the milligram numbers on product labels can be misleading.

Selank is not FDA-approved for human use in the United States, and no regulatory body publishes an official selank dosing guide. The ranges above come from small studies and user reports, and individual responses vary widely.

How Much Selank Should You Take? What Changes the Number

There is no single correct amount, because several variables shift the effective range. A selank protocol that suits one researcher may be too high or too low for another.

• Body weight: weight-based research dosing of 10-30 mcg/kg produces very different totals for a 60 kg and a 100 kg person.
• Route: intranasal selank is absorbed less efficiently than an injection, so nasal protocols often use a similar or slightly higher dose.
• Formulation: plain selank, N-acetyl selank amidate, and blended products are not dose-equivalent.
• Frequency: splitting 500 mcg into two 250 mcg doses produces a flatter effect curve than a single 500 mcg dose.
• Sensitivity: first-time researchers generally start at the low end of the range.

A selank dosing protocol typically starts at 250 mcg once daily and increases only after several days of observation. Threads asking how much selank per day is reasonable usually get answers between 250 mcg and 1 mg, which reflects how little consensus exists.

Selank Injection Dosage vs Nasal Spray Dosage

Nasal administration is the route used in most published selank research, and it is the format most vendors sell. A selank nasal spray dosing schedule usually calls for 250 mcg per nostril, two or three times per day.

Subcutaneous injection delivers a larger fraction of the peptide into circulation, so some users inject the same microgram amount just once daily. A selank subcutaneous dosage above 500 mcg per injection is rarely reported. Anyone researching selank injection dose details should note that injection adds sterility and infection risks that nasal use does not.

People often compare formats across peptides: a cjc-1295 no dac dosage chart or a mots c dosage chart will follow the same vendor-style presentation you see for selank. Researchers exploring sleep or metabolic compounds also review a dsip 5mg dosage or kisspeptin-10 dosage for side-by-side comparison.

Selank 5 mg and 10 mg Vial Math

Vials are sold by total peptide weight, not by dose. To convert a label into a syringe volume, divide the desired dose by the concentration after reconstitution.

A selank 10mg dosage is therefore not a fixed number, since it depends entirely on how much diluent you add. More diluent makes each unit smaller and the dose easier to fine-tune, while less diluent creates a tiny injection volume that is harder to measure accurately.

Selank Cycle Length, Timing, and Stacking With Semax

Russian studies commonly used selank for 10 to 14 days, and many users extend that to two or four weeks. Doses are usually taken in the morning and early afternoon to avoid interfering with sleep.

A semax and selank dosage combination is popular because the two peptides are frequently discussed together. A common selank semax blend dosage is 250 mcg of each peptide once daily, taken intranasally in the morning. Selank peptide dosing is not cumulative, so no taper is required at the end of a cycle.

Safety, Sourcing, and Legal Status

Selank is not approved by the FDA for human use, and products sold online are labeled for research purposes only. Purity, sterility, and actual peptide content are not verified by any regulator.

Reported side effects include nasal irritation, headache, drowsiness, and dizziness. People with autoimmune conditions, those who are pregnant or breastfeeding, and anyone taking prescription medication should talk with a healthcare professional before using selank in any form.

Nothing in a selank dosage chart substitutes for advice from a licensed clinician who knows your health history.

Because dosing information for selank is inconsistent, the safest approach is to use the lowest amount in the published range, document what you observe, and avoid stacking multiple unapproved peptides at once.
