Semax is a synthetic heptapeptide investigated in neurobiology. The linked experiment examined its interaction with enkephalin-degrading enzymes in human serum, a mechanistic question rather than a test of everyday cognitive performance.

Official source ↗PeptIQ’s reported value has not been matched here to a primary human PK study for the exact molecule and route. Treat it as a reference estimate, not an established dosing interval.
Half-life describes concentration falling by half. It does not set a dosing interval, a storage period or a drug-test detection window.
Kinetics source ↗The reference describes differing BAC/sterile-water practices. Route, preservative compatibility and the exact preparation determine the choice.
Bacteriostatic water contains a preservative; plain sterile water does not. Preservative presence does not by itself establish compatibility or a mixed medicine’s usable period.
Preparation source ↗Biochemical activity cannot establish a personal cognitive-enhancement dose or route of administration.
Check that a source concerns the same molecule, formulation, route and population. A study of cells, animals or a different product cannot confirm the contents of a vial.
Biochemical research on peptide breakdown and signaling.
Learn to read a study →Each entry keeps one schedule’s amount, frequency and cycle together. Community references, individual reports, clinical trials and prescription products describe different kinds of use. A missing duration or break stays marked as not reported.
Amounts describe mass in mg or mcg. Syringe units describe volume and depend on concentration. A cycle break is different from days off within a week.
Choose an option to explore its amounts, timing and cycle.
| When | Amount & frequency |
|---|---|
| Weeks 1–2 | 300 mcg daily |
| Weeks 3–4 | 500 mcg daily |
| Weeks 5–6 | 600 mcg daily |
| Weeks 7–8 | 800 mcg daily |
An individual account using ordinary Semax. Acetylated and amidated variants are separate molecules.
A peptide name and vial mass cannot determine a compatible diluent, powder displacement, storage temperature or discard date. Follow the exact product’s instructions and your pharmacist’s directions.
The injection guide concerns clinician-prescribed subcutaneous medicines; it does not establish that a research-labeled material can be injected.
Start with the formulation: dry powder, prepared solution, pen, tablet and topical product can have different instructions.
General health habits and consistent observations help you assess changes. They are not evidence that a peptide’s effects will be amplified.
Use a regular sleep/wake schedule and note changes in sleep quality alongside symptoms or training.
CDC · sleep habits ↗Choose activity that fits your health and ability. Aerobic movement and muscle-strengthening work are part of general adult activity guidance.
CDC · adult activity ↗What to record: Record sleep, stress, symptoms and other medicines consistently. These can change perceived concentration and mood.
Check dates are editorial references, not a medical review certificate. Labels and evidence can change; consult the linked current document.
Opening values and worked examples illustrate arithmetic; they are not preparation instructions or recommended amounts. Selecting a compound labels the calculation and does not supply a dose or powder-volume correction.
Enter the documented vial mass, preparation information and target amount to see how mass and volume connect.
20 mg in an assumed final 1 mL gives 20 mg/mL. An entered 1 mg corresponds to 0.05 mL, or 5 U-100 units, with 20 theoretical portions before losses.

Concentration = mass ÷ final volume
5 mg ÷ 1 mL = 5 mg/mLVolume = target mass ÷ concentration
1 mg ÷ 5 mg/mL = 0.2 mLU-100 markings = volume × 100
0.2 mL × 100 = 20 unitsComplete portions = floor(vial mass ÷ amount per portion).
Displayed numbers are rounded for readability; the calculation uses unrounded values.
