Thymosin Alpha-1 (10 mg Vial) Dosage Protocol

Quickstart Highlights

Thymosin Alpha-1 (Tα1) is a 28–amino acid peptide originally isolated from the thymus gland, recognized for its broad immunomodulatory properties^[1]. It has been investigated as an immune enhancer in chronic viral infections (hepatitis B/C, HIV/AIDS) and critical illness (sepsis, COVID-19)^[2]^[3]. This educational protocol presents a once‑daily subcutaneous approach using a practical dilution for clear insulin‑syringe measurements.

Reconstitute: Add 3.0 mL bacteriostatic water → ~3.33 mg/mL concentration.

Typical daily range: 300–500 mcg once daily (gradual titration).

Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U‑100 insulin syringe.

Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F) or freeze at −20 °C (−4 °F); after reconstitution, refrigerate and use within 7 days.

Dosing & Reconstitution Guide

Subcutaneous, once daily

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

Week	Daily Dose (mcg)	Units (per injection) (mL)
Week 1	300 mcg (0.3 mg)	9 units (0.09 mL)
Weeks 2–8	500 mcg (0.5 mg)	15 units (0.15 mL)

Frequency: Inject once daily subcutaneously. This 8‑week protocol begins at 300 mcg to assess tolerance, then increases to a maintenance dose of 500 mcg daily from Week 2 onward. The 500 mcg daily dose yields ~3.5 mg/week, consistent with clinical dosing ranges^[4]^[5]. Treatment durations of 8–16 weeks are commonly reported in literature.

For ≤10‑unit (≤0.10 mL) administrations, consider 30‑ or 50‑unit insulin syringes for improved readability.

Reconstitution Steps

Draw 3.0 mL bacteriostatic water with a sterile syringe.

Inject slowly down the vial wall; avoid foaming.

Gently swirl/roll until dissolved (do not shake).

Label with reconstitution date and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–16 week daily protocol with gradual titration.

Peptide Vials (Thymosin Alpha-1, 10 mg each):

8 weeks ≈ 3 vials (26.6 mg total)
12 weeks ≈ 5 vials (40.6 mg total)
16 weeks ≈ 6 vials (54.6 mg total)

Insulin Syringes (U‑100):

Per week: 7 syringes (1/day)
8 weeks: 56 syringes
12 weeks: 84 syringes
16 weeks: 112 syringes

Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.

8 weeks (3 vials): 9 mL → 1 × 10 mL bottle
12 weeks (5 vials): 15 mL → 2 × 10 mL bottles
16 weeks (6 vials): 18 mL → 2 × 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
