Thymalin
Also known as: Thymic peptide complex
Thymalin is a Khavinson bioregulator extracted from the thymus gland. It supports immune function, particularly T-cell activity, and has anti-aging properties.
Beginner Basics
Plain-English guide to Thymalin
What it does
Thymalin is a natural extract from the thymus gland that helps activate your immune system's T-cells, which are your body's defense fighters. Researchers typically use it to support overall immune function and explore potential anti-aging effects.
Typical dose
Researchers commonly study 10-20 mg injected once daily, either under the skin or into muscle, using a cycle of 5-10 days on followed by 20+ days off.
When to inject
Evening injections are typically recommended, with researchers cycling the peptide on and off rather than using it continuously.
Storage
Keep the dry powder in the refrigerator before mixing. After you mix it with water, store the liquid in the refrigerator and use it within the cycle period.
First-timer tip
Start with the lower dose (10 mg) and follow the on-off cycle strictly-this cycling approach is key to how researchers use Thymalin rather than daily continuous use.

Research Areas
Side Effects
Mild redness, warmth, or slight swelling at the injection site. Typically resolves within 1-2 hours. Minimize by rotating injection sites, allowing solution to reach room temperature, and using proper injection technique. Apply ice if needed.
Localized itching or urticaria (hives) at injection site or systemic mild rash. May occur in individuals with sensitivity to animal-derived peptides. Discontinue use and consult a healthcare provider if symptoms develop.
Mild headache reported in some users during the first few days of a cycle. Usually self-resolving. Stay well-hydrated and consider timing injections in the evening to minimize daytime impact.
Transient low-grade fever or chills may occur as part of immune system activation. Typically resolves within 24 hours. This may reflect immune stimulation rather than infection. Monitor temperature; seek medical evaluation if fever exceeds 38.5°C (101.3°F).
Mild tiredness or general malaise during the first 1-3 days of a cycle. Usually resolves as the body adapts. Ensure adequate sleep and hydration.
Mild nausea, stomach discomfort, or loose stools reported rarely. Typically mild and self-resolving. Take with food if nausea occurs; ensure adequate hydration.
Severe allergic reaction with difficulty breathing, throat swelling, or severe hypotension is extremely rare but requires immediate emergency medical attention. Discontinue use immediately and call emergency services. Individuals with known peptide allergies should avoid use.

Reconstitution Guide
Do not use saline or bacteriostatic saline, use only bacteriostatic water for reconstitution
Do not shake the vial vigorously; gentle swirling prevents peptide degradation
Discard immediately if the solution appears cloudy, discolored, or contains visible particles
Use within 30 days of reconstitution when stored at 2-8°C
Do not freeze the reconstituted solution; freezing may denature the peptide

Molecular and Pharmacological Data
Thymalin is a thymic peptide bioregulator that enhances T-cell maturation and immune function by supporting thymic hormone activity. It promotes the differentiation of T-lymphocytes in the thymus gland and modulates immune response through peptidergic signaling pathways. The peptide exhibits immunomodulatory and potential anti-aging effects by restoring age-related decline in thymic function and cellular immunity.
