Semax + Selank Blend (10 mg vial)

Once daily subcutaneous protocol for cognitive and neurological research.

This pairs the two Russian nootropics: Semax for the stimulation and focus side, Selank for calm without sedation. The protocol below doses both together in the morning, amounts referring to each component.

Quick answer: at the standard 10 mg + 1 mL reconstitution, a 500 mcg each dose of Semax + Selank Blend draws 10 units (0.1 mL) on a U-100 insulin syringe, once daily subcutaneous.

Schedule
Once daily subcutaneous, 4-8 weeks
Reconstitution
10 mg vial + 1 mL bac water (10 mg/mL)
Storage
Lyophilized: frozen or 2-8 °C; reconstituted: refrigerated, use within 28 days
Evidence
The published work on this compound is animal or cell-culture research. No human dosing schedule exists to cite.

Dosing & reconstitution

Community-reported ranges. These are the amounts commonly reported in user communities and vendor protocols, not from controlled human trials. They are listed here because they are what most people reference in practice.

Frequency: Once daily subcutaneous
Typical duration: 4-8 weeks

Reconstitution: 10 mg vial + 1 mL bacteriostatic water = 10 mg/mL. Units below are for a U-100 insulin syringe at this concentration.

PhaseDoseUnits per injection
Weeks 1-2300 mcg each6 units (0.06 mL)
Weeks 3-4500 mcg each10 units (0.1 mL)

Units = (dose ÷ concentration) × 100 on a U-100 syringe. Change the vial size or water volume and the calculator redoes all of this for you.

Semax + Selank Blend dosing — what the literature actually supports

Animal data only. Each component has its own Russian clinical literature as a separate intranasal product. The combination in a single injectable vial has not been studied, so there is no schedule to cite for the blend. The stack calculator will give you the per-component amount in a draw, which is the answerable part.

We publish a schedule when there is a citable human source and we say so when there is not. Filling this space with a number nobody measured would make the page look more complete and be worth less than nothing to you.

Reconstitution and measurement

This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre. Common vials for Semax + Selank Blend: 10 mg total.

  1. Wipe the stoppers of both vials with an alcohol swab and let them dry.
  2. Draw the bacteriostatic water with a sterile syringe and inject it slowly down the inside wall of the peptide vial — never straight onto the powder.
  3. Swirl gently until the solution is clear. Do not shake; foaming and agitation damage peptides.
  4. Label the vial with the date and concentration, and refrigerate at 2–8 °C protected from light.

Storage and stability

Dry powder
Cold, dark and dry. Lyophilized peptide is the stable form — keep it that way until you intend to use it.
After reconstitution
Refrigerate at 2–8 °C, protect from light, and plan around a limited window. Do not freeze a reconstituted vial — freeze-thaw damages peptides.
Mixing
Run bacteriostatic water down the inside wall of the vial rather than onto the powder, then swirl. Never shake.
Inspect before use
A clear solution is expected. Cloudiness or particles mean discard, not use.

Supplies math

Whatever amounts your research uses, the planning arithmetic is the same. The calculator runs all of this per compound.

Vials
Doses per vial = vial size in mg divided by your per-dose amount in mg. The calculator on this page runs that arithmetic for any vial size and amount you enter.
Syringes
One sterile U-100 insulin syringe per injection, plus roughly 10% spares for bent tips and mis-draws. Daily protocols run 30 or 31 per month.
Bacteriostatic water
1 to 3 mL per vial reconstituted. A single 10 mL bottle covers 3 to 10 vials, so one bottle usually outlasts several vials.
Alcohol swabs
Two per injection: one for the vial stopper, one for the site. A 100-count box covers about 7 weeks of daily work.

Supplies by protocol length

Based on the maintenance dose above (500 mcg each, once daily subcutaneous) and a 10 mg vial reconstituted with 1 mL.

DurationInjectionsVialsSyringesBac waterSwabs
8 weeks563 x 10 mg621 x 10 mL112
12 weeks845 x 10 mg931 x 10 mL168
16 weeks1126 x 10 mg1241 x 10 mL224

Syringe count includes ~10% spares. Swabs = 2 per injection (stopper + site). Vial count assumes the full maintenance dose for the entire duration.

Important notes

Practical considerations for consistency and safety.

  • Use a new sterile insulin syringe for each injection and dispose in a proper sharps container.
  • Rotate injection sites (abdomen, thighs, upper arms) systematically to reduce local irritation and avoid lipohypertrophy.
  • Inject slowly and steadily; wait a few seconds before withdrawing the needle to ensure complete delivery.
  • Administer at the same time each day for consistent levels. Setting a daily reminder helps maintain the schedule.
  • This compound lacks controlled human safety data. Start with the lowest reported amount and increase gradually while monitoring for any adverse reactions.
  • The 10 mg vial size is standard for this compound. Reconstitute with 1 mL bacteriostatic water for a convenient concentration.

How Semax + Selank Blend works

Combines the two Russian-developed regulatory peptides in one vial. They came out of the same research programme and are often discussed together, but they have different parent molecules and different proposed effects.

Benefits & side effects

Potential benefits

  • Combined cognitive + anxiolytic effects
  • Synergistic nootropic and mood support
  • Both pathways addressed simultaneously
  • Convenient single-injection protocol

Possible side effects

  • Combined side effects of both compounds
  • Injection site reactions
  • Headache possible
  • Generally well tolerated

This list reflects published literature and community reports. Individual responses vary. Not medical advice.

Bloodwork worth tracking

The community-standard practice is a baseline panel before starting, a recheck 8 to 12 weeks in, and another after time off. For Semax + Selank Blend, the markers most worth watching:

CMPCBC

Typical time off: 4 wks

Lab panels are how a research protocol stays honest: numbers move before symptoms do. Interpretation belongs with a clinician. Not medical advice.

Lifestyle factors

None of the literature above was run on a background of poor sleep and no protein. These variables move outcomes more reliably than any compound on this site.

  • Protein in the 1.6 to 2.2 g/kg range preserves lean mass through any body-composition phase.
  • Resistance training 2 to 4 days per week plus 150+ minutes of weekly aerobic work reinforces whatever the protocol is doing.
  • Sleep is the recovery window: 7 to 9 hours at consistent times.
  • Hydration matters more than usual on compounds with GI or flushing effects: 2 to 3 liters daily.
  • Track the variables that matter: weigh-ins, measurements, photos, and labs at sensible intervals.

Subcutaneous technique and practical notes

General best practice from clinical injection guidance — the same fundamentals nurses are taught, none of it specific to any compound.

Fresh sterile syringe, every time
Reusing needles dulls the tip, hurts more, and is the easiest contamination route. Dispose of used syringes in a sharps container, not the bin.
Rotate sites
Abdomen (5 cm clear of the navel), thighs, upper arms. Rotating systematically prevents localised irritation and lipohypertrophy.
Slow and steady
Pinch a skinfold, insert at 45–90°, inject slowly, and wait a few seconds before withdrawing. Subcutaneous injections are not aspirated.
Write it down
Log the date, amount and site. A record is the only way to keep any research protocol consistent — and the first thing to review if anything looks off.
