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.

Protocol overview
Dosing & reconstitution
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.
| Phase | Dose | Units per injection |
|---|---|---|
| Weeks 1-2 | 300 mcg each | 6 units (0.06 mL) |
| Weeks 3-4 | 500 mcg each | 10 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
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.
- Wipe the stoppers of both vials with an alcohol swab and let them dry.
- 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.
- Swirl gently until the solution is clear. Do not shake; foaming and agitation damage peptides.
- Label the vial with the date and concentration, and refrigerate at 2–8 °C protected from light.
Storage and stability
Supplies math
Whatever amounts your research uses, the planning arithmetic is the same. The calculator runs all of this per compound.
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.
| Duration | Injections | Vials | Syringes | Bac water | Swabs |
|---|---|---|---|---|---|
| 8 weeks | 56 | 3 x 10 mg | 62 | 1 x 10 mL | 112 |
| 12 weeks | 84 | 5 x 10 mg | 93 | 1 x 10 mL | 168 |
| 16 weeks | 112 | 6 x 10 mg | 124 | 1 x 10 mL | 224 |
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.
Quick answers
How many syringe units is a 500 mcg each dose of Semax + Selank Blend?
At the standard reconstitution of 10 mg with 1 mL bacteriostatic water (10 mg/mL), a 500 mcg each dose draws 10 units (0.1 mL) on a U-100 insulin syringe.
How do you reconstitute Semax + Selank Blend?
Add 1 mL of bacteriostatic water to the 10 mg vial for 10 mg/mL. Inject the water slowly down the inside wall of the vial, swirl gently without shaking, and refrigerate at 2 to 8 °C after mixing.
How long does a 10 mg vial of Semax + Selank Blend last?
About 20 maintenance doses of 500 mcg each, roughly 2.9 weeks at once daily subcutaneous.
Does Semax + Selank Blend have human trial data?
No. The evidence base is animal and cell studies; the practical dosing shown is community convention, and the page labels it that way.
How does Semax + Selank Blend work?
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.
Sourcing Semax + Selank Blend
Whatever you are working with, the documentation matters more than the price. Ask for a batch certificate of analysis whose lot number matches the vial you actually receive — a COA for a different batch tells you nothing about yours.
