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 5 mg vial → ~1.67 mg/mL (1,667 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 ~1.67 mg/mL, 1 unit ≈ 16.7 mcg; 500 mcg ≈ 30 units and 1000 mcg ≈ 60 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.

Dosing & Reconstitution Guide

A single practical dilution with accurate once-daily dosing, step by step

Standard / Gradual Approach (3 mL = ~1.67 mg/mL)

Phase / Week(s)	Dose & Frequency	Volume (U-100 units / mL)
Weeks 1–4	0.5 mg (500 mcg, 1× daily)	~30 units (0.30 mL)
Weeks 5–8	1 mg (1,000 mcg, 1× daily)	~60 units (0.60 mL)

Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration ~1.67 mg/mL (1,667 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 ~1.67 mg/mL, 1 unit ≈ 16.7 mcg on a U-100 syringe. Using the large 3.0 mL dilution keeps every dose at 30 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.
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 (5 mg/mL) dilution; at that strength 6 mg ≈ 120 units, which exceeds a 100-unit syringe and may need more than one vial or split injections[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 30 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 5 mg vial is roughly one week of dosing at the ~5 mg/week average, so plan about one vial per week.
8 weeks: ~8 vials
12 weeks: ~12 vials
16 weeks: ~16 vials
Per injection: 1 syringe
8 weeks (once daily): ~56 syringes
16 weeks (once daily): ~112 syringes
Use ~3.0 mL per 5 mg vial for reconstitution.
8 weeks (8 vials): ~24 mL → 3 bottles
16 weeks (16 vials): ~48 mL → 5 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 (5 mg/mL) dilution.
▪Reconstitution: 3.0 mL bacteriostatic water per 5 mg vial gives ~1.67 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.

▪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].
▪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.

▪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.
▪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.
▪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.
