Dosing & Reconstitution Guide
A single practical dilution with accurate once-daily dosing, step by step
Standard / Gradual Approach (3 mL = ~3.33 mg/mL)
Reconstitute: Add 3.0 mL bacteriostatic water to one 10 mg vial → final concentration ~3.33 mg/mL (3,333 mcg/mL).
Typical daily range: 0.5–1 mg (500–1,000 mcg) once daily, commonly run over a 4–8 week cycle for general cognitive support or mild neuroprotection.
Easy measuring: At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg on a U-100 syringe. Using the large 3.0 mL dilution keeps every dose at 15 units or more for excellent measuring accuracy.
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the mixed solution.
Why Semax draws research interest
These are the directions researchers and the peptide community most often explore Semax for — so you know you’re in the right place. They describe what is being studied, not proven benefits, approved uses, or promised results.
Cognition & nootropic
Most-searched use: investigated in research as a nootropic for memory, learning, and mental performance; investigational, not approved.
Neuroprotection
Studied in preclinical and animal research on protecting neurons after ischemic and hypoxic injury; an ACTH 4-10 analog.
Focus & attention
Explored in research on attention, concentration, and mental fatigue; investigational and not an approved therapy.
Mood & stress resilience
Researched for effects on anxiety-like behavior, stress, and BDNF signaling, largely in animal-only studies.
Evidence ranges from early laboratory work to clinical trials depending on the use — the sections below cover the actual data and sources.
Quickstart Highlights
Semax is a synthetic peptide — an analog of ACTH(4–10) carrying a Pro-Gly-Pro tail (sequence Met-Glu-His-Phe-Pro-Gly-Pro) — studied as a neuroprotective / nootropic agent that raises BDNF and modulates monoamine and melanocortin systems[1][2]. This page presents subcutaneous injection figures used by the research community, but note the validated, approved route for Semax is intranasal. Semax is approved as a medicine only in Russia; in the US and EU it is not approved and is sold as a research chemical — presented for research and educational use only.
Add 3.0 mL bacteriostatic water to one 10 mg vial → ~3.33 mg/mL (3,333 mcg/mL), the largest practical dilution for accurate dosing.
0.5–1 mg (500–1,000 mcg) once daily by subcutaneous injection, often run as 4–8 week cycles. Intranasal is the validated route.
At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg; 500 mcg ≈ 15 units and 1000 mcg ≈ 30 units on a U-100 syringe.
Lyophilized: store at −20 °C (−4 °F); once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the solution.
Important: Start with the Prep & Injection Guide — it covers the preparation and safety basics every protocol on this site assumes.
Frequency: one subcutaneous injection once daily (or every other day), most often morning. A separate advanced / short-course protocol — up to 6 mg daily for ~10 days, sometimes referenced in post-stroke settings — uses a 1 mL (10 mg/mL) dilution; at that strength 6 mg ≈ 60 units, which fits within a single 100-unit insulin syringe[3]. These figures come from reference protocols and the research community, not from approved human dosing; the validated clinical route for Semax is intranasal.
Reconstitution Steps
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
Release it slowly down the vial’s inner wall to limit foaming.
Swirl or roll gently until fully dissolved — don’t shake.
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.
The 3.0 mL dilution is deliberately large so each dose reads at 15 units or more, where U-100 syringe markings are most precise. Avoid freezing the reconstituted solution, since freeze–thaw can denature the peptide.
Supplies Needed
Quantities below assume an 8–16 week course of once-daily injections with gradual titration.
A 10 mg vial is roughly two weeks of dosing at the ~5 mg/week average, so plan about one vial every two weeks.
- 8 weeks: ~4 vials
- 12 weeks: ~6 vials
- 16 weeks: ~8 vials
- Per injection: 1 syringe
- 8 weeks (once daily): ~56 syringes
- 16 weeks (once daily): ~112 syringes
Use ~3.0 mL per 10 mg vial for reconstitution.
- 8 weeks (4 vials): ~12 mL → 2 bottles
- 16 weeks (8 vials): ~24 mL → 3 bottles
One for the vial stopper + one for the injection site each day.
- Per injection: 2 swabs
- 8 weeks (once daily): ~112 swabs → 1–2 boxes
Protocol Overview
A concise summary of the once-daily regimen, drawn from commonly cited reference protocols.
- ▪Goal: Explore neuroprotective and nootropic effects (BDNF support, attention, stroke-recovery research) — reported mainly in limited Russian studies, not established by US/EU trials[3][5].
- ▪Schedule: Once-daily (or every-other-day) subcutaneous injections over a 4–8 week cycle; short, more intensive courses are sometimes referenced for stroke research. Intranasal is the validated route.
- ▪Dose Range: 0.5–1 mg per day (standard); an advanced short-course protocol references up to 6 mg/day for ~10 days using a 1 mL (10 mg/mL) dilution.
- ▪Reconstitution: 3.0 mL bacteriostatic water per 10 mg vial gives ~3.33 mg/mL for accurate unit measurements.
- ▪Storage: Keep the dry vial frozen at −20 °C (−4 °F); once mixed, refrigerate at 2–8 °C and do not freeze the solution.
Dosing Protocol
A suggested daily titration approach based on common reference doses.
- ▪Start: Begin at 500 mcg once daily to gauge tolerability.
- ▪Titrate: Increase by roughly 100–150 mcg every two weeks as tolerated.
- ▪Target: Reach about 750–1000 mcg daily by weeks 5–12.
- ▪Cycle Length: Typically 8–12 weeks; some references extend to ~16 weeks.
- ▪Timing: Inject at a consistent time each day and rotate injection sites systematically.
Storage Instructions
Correct storage is what preserves the peptide’s stability and activity.
- ▪Lyophilized: Hold the dry vial at −20 °C (−4 °F) in dry, dark conditions and limit moisture exposure[7].
- ▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 28 days; do not freeze the mixed solution, as freezing can denature peptides[8].
- ▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form, and keep the solution clear of heat and direct light.
- ▪Freeze–thaw: Avoid repeated freeze–thaw cycles of the reconstituted solution.
Important Notes
Practical points that keep daily administration safe and consistent.
- ▪Sterile technique: Use a fresh sterile U-100 insulin syringe each time and drop it straight into a puncture-proof sharps container afterward.
- ▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[9].
- ▪Slow injection: Push the plunger slowly and pause a few seconds before withdrawing the needle to prevent backflow.
- ▪Recordkeeping: Log the daily dose, injection site and any observations to keep the protocol consistent.
- ▪Regulatory note: Semax is approved as a medicine only in Russia; it is not FDA- or EMA-approved and is sold elsewhere as a research chemical, not for human use[10].
How This Works
Semax is a synthetic peptide — a short analog of ACTH(4–10) with an added Pro-Gly-Pro tail (sequence Met-Glu-His-Phe-Pro-Gly-Pro) that resists rapid enzymatic breakdown[1][2]. Unlike ACTH itself, it is reported to act without meaningful corticotropic (steroid-releasing) activity.
Its most cited proposed mechanism is an increase in brain-derived neurotrophic factor (BDNF) and its receptor TrkB, alongside modulation of monoaminergic systems (dopamine, serotonin) and the melanocortin pathway[3][4]. In preclinical and limited clinical work it has been described as neuroprotective and nootropic, with effects on attention and recovery after ischemic injury.
Route matters: the validated and approved form of Semax is intranasal (drops or spray). Subcutaneous injection — the dosing shown on this page — is a research-community practice, not the clinical route, and has not been validated in approval studies.
Important caveat: human efficacy data for Semax are largely Russian and limited, and methodological quality varies. Cognitive and stroke-recovery claims should be read as hypotheses, not established outcomes — the cognitive effects in particular should not be overstated.
Semax is approved as a medicine only in Russia (since ~1994, for cerebrovascular and cognitive disorders). In the US and EU it is not approved and is sold as a research chemical, presented here for research and educational purposes only.
Lifestyle Factors
Habits that may support cognitive function and neurocognitive benefit alongside the protocol.
- ▪Nutrition: Eat a balanced diet rich in antioxidants and essential nutrients to support brain health.
- ▪Mental stimulation & exercise: Combine regular physical activity with cognitive challenges (reading, learning, problem-solving) to support mental clarity.
- ▪Sleep: Aim for 7–9 hours of quality sleep, which is critical for memory consolidation and brain health.
- ▪Stress & sleep: Manage stress and prioritize high-quality sleep, since both strongly influence cognition and mood.
Potential Benefits & Side Effects
What preclinical work and limited (mostly Russian) clinical reports describe; human evidence is limited and individual results vary.
Potential Benefits
- ▪Cognition & attention (reported): Often used to support focus and mental clarity; small studies and anecdote suggest nootropic effects, which should not be overstated[3][4].
- ▪Neuroprotection (preclinical / limited clinical): Raises BDNF and has been studied for neuroprotection and recovery after ischemic injury, mainly in Russian research[5].
- ▪Tolerability: Generally reported as well tolerated at typical doses, most safety experience coming from intranasal use; injectable safety data are limited.
- ▪Note on humans: Human efficacy data are largely Russian and limited; cognitive and stroke claims are not established by US/EU trials and should be treated as hypotheses[5].
Common Side Effects
- ▪Injection-site reactions: Mild redness, tenderness or soreness can occur; rotating sites helps.
- ▪Reported effects: Mild headache, restlessness or slight blood-pressure changes are occasionally reported; long-term injectable safety data are limited, so caution and monitoring are advised.
- ▪Route note: The validated, approved route for Semax is intranasal; subcutaneous injection is a research-community practice only.
Injection Technique
General subcutaneous technique, following established clinical best-practice guidance.
Pre-Injection Preparation
- ▪Wash your hands well with soap and water.
- ▪Wipe the vial stopper with an alcohol swab and let it air-dry.
- ▪Choose a site (abdomen, thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully.
- ▪Draw the intended dose, then check for air bubbles and push any out.
Injection Procedure
- ▪Pinch a skinfold at the chosen site between thumb and forefinger.
- ▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin).
- ▪Skip aspiration for subcutaneous shots — it isn’t needed.
- ▪Press the plunger slowly and steadily until it’s fully down.
- ▪Wait 5–10 seconds, then pull the needle straight out to prevent leakage.
Post-Injection Care
- ▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle.
- ▪Return the reconstituted vial to the fridge right away.
- ▪Rotate the injection site each day to prevent irritation and lipohypertrophy[9].
- ▪Watch the site for excess redness, swelling, or signs of infection.

Semax — frequently asked questions
How do I reconstitute a 10 mg vial of Semax?
Wipe the stopper with an alcohol swab, then inject your bacteriostatic water slowly down the inside wall of the vial. Let it sit and gently swirl until dissolved — never shake. Store the mixed vial in the refrigerator and draw doses with an insulin syringe. Use the calculator above to turn any dose into syringe units.
How much bacteriostatic water should I add to Semax?
There is no single correct amount — more water simply spreads the same 10 mg of peptide across a larger volume, which makes small doses easier to measure accurately. 1 to 3 mL per vial is typical. Enter your chosen volume in the calculator above to see the resulting concentration and syringe units.
What do the "units" on an insulin syringe mean?
On a U-100 insulin syringe, 100 units equal 1 mL, so 1 unit equals 0.01 mL. The calculator above converts your draw volume into these units automatically so you can measure without doing the math by hand.
How should I store Semax after mixing?
Keep the reconstituted vial refrigerated at roughly 2 to 8 degrees Celsius, away from light, and avoid freezing it. Reconstituted research peptides are generally used within a few weeks. Always follow the specific guidance supplied with your product.
How many doses does a 10 mg vial of Semax provide?
Divide the vial strength of 10 mg by the amount you use per injection. The calculator above reports this as "doses per vial" the moment you enter a dose.
Is Semax approved for human use?
No. Semax is sold strictly for laboratory and research purposes and is not approved by the FDA or other regulators for human use. Everything on this page is research information, not medical advice — consult a licensed healthcare professional before any use.
