Thymosin Alpha-1 is a naturally occurring peptide involved in immune system regulation. When prescribed in compounded form under medical supervision, TA-1 is used off-label to support immune modulation, immune resilience, and healthy immune signaling. It has been studied for its role in helping regulate immune response and supporting immune balance in certain clinical settings.

TA-1 may be appropriate for individuals seeking to support immune function, immune resilience, or overall wellness as part of a longevity-focused care plan. It is sometimes considered for patients experiencing frequent illness, immune stress, or age-related changes in immune regulation, under the guidance of a licensed healthcare provider.

Each order includes two 5 mL vials of Thymosin Alpha-1 at a concentration of 2 mg/mL, providing 20 mg total per order. Dosing is determined by your licensed provider based on your individual protocol. A commonly prescribed range is 0.2–0.4 mg per day, taken five days per week with two days off. At the upper end of this range (0.4 mg, five days per week), a single order is designed to last approximately 8 weeks. Please follow the dosing instructions provided by your healthcare provider to ensure safe and appropriate use.

Thymosin Alpha-1 is administered via subcutaneous injection. Common injection sites include the lower abdomen or thigh. Do not inject into any area where there is an active skin infection. Your medication will come with detailed instructions, and your healthcare provider can guide you through proper injection technique and safe handling.

Yes. Thymosin Alpha-1 protocols often include a range of dosing, so patients prescribed the lower end of that range may have medication remaining. For safety and quality, any remaining medication should be discarded 28 days after first use, even if there is supply left in the vial.

The medication should be refrigerated immediately after arrival to maintain quality. The medication should be stored at 2-8°C (36-46°F). Please keep the vial away from sunlight and avoid shaking it.
