Thymosin Alpha-1 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 5 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.

U-100 math for listed Thymosin Alpha-1 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 |
|---|---|---|---|
| 5 mg | 50 | 25 | 16.7 |
| 10 mg | 100 | 50 | 33.3 |
Other names in the library: thymalfasin, ta1, Thymosin Alpha 1 (10MG), Thymosin Alpha-1 — 10mg / Premium, Thymosin Alpha-1 — 5mg / Premium. The cited evidence and any approval concern the studied or labeled preparation. Oral, nasal, cosmetic and research-market versions do not inherit product approval or proven efficacy. Listed sizes: 5 mg, 10 mg. A seller title is a listing. It does not prove the vial matches a paper.
Peptide studied for immune modulation.

not approved. No US therapeutic product approval is established by this curated source set; other countries and products may differ.
Compounding
not established. Compounded products do not carry FDA product approval; legal eligibility is not established here.
Research
investigational. Evidence varies by illness and country; general immune or longevity benefit is not established.
Sport
unknown. Not individually verified; consult the current sport rules. Absence of a listing is not permission.
We mark the cited papers as C for Evidence varies by illness and country; general immune or longevity benefit is not established. and No general wellness indication established.. Limited or preclinical evidence; the grade is not a safety rating. Risks on the record: Safety is incomplete; absence of reports does not establish safety.
We mark the cited papers as C. That is our label for how strong those papers are. It does not say the compound works.
The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.
Half-life on file: no single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied. Follow the label on the vial you hold. This page does not set a throw-away date after you add water.
People using PepBear often log: Existing clinician-directed records, symptoms and dated health measurements. Record missing data; trends do not demonstrate causation.

The calculator turns numbers you type into U-100 units. Trial or label amounts stay as cited facts.
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.
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.
A licensed clinician must interpret the evidence for your situation. This entry provides education, not treatment instructions. Not medical advice. PepBear does not pick a dose, a cycle, or a seller.
