MechanismSemax is a synthetic heptapeptide analog of ACTH(4–10) developed in Russia and studied primarily for cognitive enhancement and neuroprotection [1] [2] . While intranasal administration is most common in clinical literature, subcutaneous injection offers a convenient once‑daily alternative for research purposes [1] [4] .
Dosing300–800 mcg once daily (gradual titration recommended).
ReconstitutionAdd 3.0 mL diluent to a 10 mg vial.
StorageLyophilized: freeze at −20 °C (−4 °F) ; after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) ; avoid freeze–thaw cycles [2] [9] .

Dosing & Reconstitution Guide

A practical calculator-ready setup based on the imported protocol reference. Use these values as a math starting point, then verify every entry against your own vial, diluent, and professional guidance.

Standard / Gradual Approach (3 mL = ~3.33 mg/mL)

Phase / setup Dose & frequency Volume / units
Weeks 1–2300 mcg9 units (0.09 mL)
Weeks 3–4500 mcg15 units (0.15 mL)
Weeks 5–6600 mcg18 units (0.18 mL)
Weeks 7–8800 mcg24 units (0.24 mL)

300–800 mcg once daily (gradual titration recommended).

Reconstitution Steps

  1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall; avoid foaming.
  3. Gently swirl/roll until dissolved (do not shake vigorously).
  4. Label and refrigerate at 2–8 °C (35.6–46.4 °F) , protected from light [2] .

Peptide Vials 8 weeks ≈ 4 vials
  • 12 weeks ≈ 6 vials
  • 16 weeks ≈ 8 vials
Insulin Syringes Per week: 7 syringes (1/day)
  • 8 weeks: 56 syringes
  • 12 weeks: 84 syringes
  • 16 weeks: 112 syringes
Bacteriostatic Water Use ~3.0 mL per vial for reconstitution.
  • 8 weeks (4 vials): 12 mL → 2 × 10 mL bottles
  • 12 weeks (6 vials): 18 mL → 2 × 10 mL bottles
  • 16 weeks (8 vials): 24 mL → 3 × 10 mL bottles
Alcohol Swabs One for the vial stopper + one for the injection site each day.
  • Per week: 14 swabs (2/day)
  • 8 weeks: 112 swabs → recommend 2 × 100‑count boxes
  • 12 weeks: 168 swabs → recommend 2 × 100‑count boxes
  • 16 weeks: 224 swabs → recommend 3 × 100‑count boxes

Protocol Overview

  • Goal: Support cognitive function, attention, and neuroprotective pathways studied in clinical literature [2] [5] .
  • Schedule: Daily subcutaneous injections for 8 weeks (extend to 12–16 weeks with cycling if desired) [4] .
  • Dose Range: 300–800 mcg daily with gradual titration; aligns with typical human nootropic dosing ranges [2] [3] .
  • Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for accurate unit measurements.
  • Storage: Lyophilized frozen; reconstituted refrigerated; use within 30 days [2] [9] .

Dosing Protocol

  • Suggested daily titration approach.
  • Start: 300 mcg daily; increase by ~100–200 mcg every 1–2 weeks as tolerated.
  • Target: 600–800 mcg daily by Weeks 5–8; adjust based on individual response.
  • Frequency: Once per day (subcutaneous) [1] [4] .
  • Cycle Length: 8 weeks continuous; optional extension to 12–16 weeks with off‑periods (e.g., 6 weeks on, 2 weeks off) [4] .
  • Timing: Any consistent time; rotate injection sites systematically.

Storage Instructions

  • Lyophilized: freeze at −20 °C (−4 °F) ; after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) ; avoid freeze–thaw cycles [2] [9] .
  • Storage: Lyophilized frozen; reconstituted refrigerated; use within 30 days [2] [9] .
  • Keep mixed and unmixed items clearly labeled so inventory and dose logs stay accurate.

04 · Good to know

Important Notes

  • Practical considerations for consistency and safety.
  • Use new sterile insulin syringes for each injection; dispose in a sharps container [7] .
  • Rotate injection sites (abdomen, thighs, upper arms) at least 1–2 inches from previous sites to reduce local irritation [7] .
  • Inject slowly; wait a few seconds before withdrawing the needle.
  • Document daily dose, injection time, and site rotation to maintain consistency.
  • Most human data are for 4–8 weeks of continuous use; longer protocols should incorporate rest periods [4] .

05 · How it works

How This Works

Semax is a synthetic heptapeptide analog of ACTH(4–10) developed in Russia and studied primarily for cognitive enhancement and neuroprotection [1] [2] .

While intranasal administration is most common in clinical literature, subcutaneous injection offers a convenient once‑daily alternative for research purposes [1] [4] .

This educational protocol presents a practical SC approach using straightforward reconstitution for accurate insulin‑syringe measurements.

The library page pairs that educational context with calculator-ready vial math, so users can understand the protocol structure and then track their own entered values in one place.

06 · Daily habits

Lifestyle Factors

  • Keep meals, training, sleep, and recovery notes in the journal so trends are easier to review.
  • Track body metrics only if they are relevant to the user's goal and approved data sources.
  • Use consistent timing and logging habits so adherence data is meaningful.

07 · What to expect

Potential Benefits & Side Effects

  • Semax observations should be recorded conservatively: expected research endpoints, tolerability notes, injection-site reactions when applicable, sleep, appetite, energy, mood, and any adverse or unusual response.
  • This section is not a claim of therapeutic benefit.

08 · Technique

Injection Technique

Pre-injection preparation
  • Wash hands with soap and water.
  • Wipe the vial stopper and chosen site with alcohol, then let both dry.
  • Confirm the vial concentration, calculator result, and intended draw amount before loading the syringe.
Injection procedure
  • Use the route and needle technique directed by a qualified professional or product instructions.
  • For subcutaneous injections, rotate sites and inject slowly to limit leakage and irritation.
  • Do not reuse needles or syringes.
Post-injection care
  • Dispose of sharps in a puncture-resistant container.
  • Return stored items promptly to the correct temperature.
  • Log dose, site, date, time, inventory change, and any observation.
