Semax calculator
Semax math uses the listed vial sizes on this card and the liquid you type. Concentration in mcg per mL is vial milligrams times 1000, divided by milliliters. A U-100 syringe has 100 marks per milliliter, so each unit is that concentration divided by 100. Example numbers so you can see the math: a 10 mg listing plus 2 mL of liquid. Change any number and the units change. Try the numbers. A research-market vial is not the same material used in a trial.

Units chart for listed Semax sizes
U-100 math for listed Semax sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 10 mg | 100 | 50 | 33.3 |
| 30 mg | 300 | 150 | 100 |
What is Semax?
N-acetyl and amidate versions have their own cards. A 30 mg listing is a listing mass. It is not a copied study amount. Nasal research solutions should not be forced into an injectable units chart without the mass and volume you actually measure.
A human therapeutic mechanism is not established in this catalog; laboratory hypotheses do not establish clinical benefit.
Regulatory status, dated 2026-10-09
Compounding
not established. Compounded products do not carry FDA product approval; legal eligibility is not established here.
Research
investigational. Preclinical studies and limited indication-specific human reports; not general cognitive-enhancement evidence.
Sport
unknown. Not individually verified; consult the current sport rules. Absence of a listing is not permission.
What the cited papers actually measured
Papers such as PMID 16986957 and 21964689 discuss mechanism and early human observations. They are not US approvals. Evidence grade in the catalog stays limited. Sport status is unverified here.
We mark the cited papers as C. That is our label for how strong those papers are. It does not say the compound works.
How long it lasts, how you store it, listed sizes
The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.
Listed sizes are 10 mg and 30 mg. Type the mass on your vial if it differs.
Risks and mix-ups already on the record
- Safety is incomplete; absence of reports does not establish safety.
- Unknown or incomplete for research formulations; this is not a clearance for use.
- Unknown or incomplete; do not infer compatibility with medications or other substances.
People using PepBear often log: Existing clinician-directed records, symptoms and dated health measurements. Record missing data; trends do not demonstrate causation.

Questions people ask
Is Semax an approved thinking drug in the US?
This source set shows no US drug approval as of Oct 9, 2026.
Can I compare Semax and Selank as a stack?
They have separate cards. This site does not pick a winner or a combined amount. A later compare page will only pair compounds with real demand and citations.
How many units is a listed Semax vial after you add water?
Units = (amount in mcg ÷ (vial mg × 1000 ÷ water mL)) × 100 on a U-100 syringe. Enter the three numbers. The chart shows the same math for each listed vial size and 1, 2 or 3 mL of liquid.
Why flag amounts under 5 units?
A U-100 barrel is easy to misread below about 5 marks. That is a measuring warning. The page does not tell you to take more.
