Thymalin

Immune System

10mg vial + 1mL BAC water = 100 units = 10mg — Amounts listed in the Dosify Me data: 2.5-10mg — Frequency: daily, 5-10 day courses — Best taken: morning, fasted

Informational only, not medical advice. Consult a licensed healthcare provider before starting or changing any protocol.

Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.

Reconstitution

This compound ships pre-mixed as a ready-to-use liquid — do not add bacteriostatic water. The units below assume the vial already holds 10 mg/mL.

Dose to syringe units

On a standard 100-unit (1 mL) insulin syringe, at the concentration above:

DoseSyringe units
2.5 mg25.0 units
5 mg50.0 units
10 mg (common)100.0 units

Amounts listed in the Dosify Me data: 2500–10000 mcg. Frequency: daily, 5-10 day courses. Timing: morning, fasted, typically 10-day courses.

The 10mg vial mixes with 1mL of BAC water to 10mg/mL (100mcg/unit), so a 10mg dose is 100 units, one full 1mL syringe.

Reading units for Thymalin

Check one row of the table above: 10000 mcg is 10 mg; 10 mg ÷ 10 mg/mL = 1 mL; 1 mL × 100 = 100 units.

What users report

Anecdotal and early-research reports, kept apart from the evidence above. Not clinically established.

Side effects

Medication caution

As a thymic, immune-modulating peptide, Thymalin's effects could work against deliberate immunosuppression. Anyone on immunosuppressant medication (organ transplant anti-rejection drugs, biologics, or similar) should talk to that prescriber before use.

Frequently asked

How many units is 2.5 mg of Thymalin?

At 10 mg/mL (the concentration every vial size mixes to), 2.5 mg of Thymalin is 25.0 units on a 100-unit insulin syringe (0.250 mL).

How many units is 5 mg of Thymalin?

At 10 mg/mL (the concentration every vial size mixes to), 5 mg of Thymalin is 50.0 units on a 100-unit insulin syringe (0.500 mL).

How many units is 10 mg of Thymalin?

At 10 mg/mL (the concentration every vial size mixes to), 10 mg of Thymalin is 100.0 units on a 100-unit insulin syringe (1.000 mL).

How much bacteriostatic water do I add to a 10 mg vial of Thymalin?

1.00 mL, which gives 10 mg/mL. This compound ships pre-mixed, so no water is added.

How often is Thymalin taken?

Daily, 5-10 day courses. Morning, fasted, typically 10-day courses Typical cycle: ~10–20 days on, then break; repeat 2×/year.
