Thymalin: uses, dosing & the facts
A thymic peptide that supports immune function and tissue regeneration. Extracted from calf thymus, helps normalize immune system activity. This is an evidence-graded reference – what it is, what it's used for, typical reported dosing, half-life, side effects, and how to track it. It is educational, not medical advice or a recommendation to use a research compound.
- • Thymalin – Longevity. A thymic peptide that supports immune function and tissue regeneration.
- • Commonly used for immune system support, tissue regeneration, wound healing.

What Thymalin is
A thymic peptide that supports immune function and tissue regeneration. Extracted from calf thymus, helps normalize immune system activity.
What Thymalin is used for
- • Immune system support
- • Tissue regeneration
- • Wound healing
- • Anti-aging and longevity
- • Autoimmune condition support
- • Viral infection recovery
These are reported/community uses, not proven clinical outcomes. Most research peptides have limited human trial data behind such claims.
Typical reported dosing
| Injectable | 5–30mg injected intramuscularly daily for 10 days, then maintenance dosing 2–3x per week |
Presented as commonly-reported patterns for information only – not a dose recommendation. Thymalin dosing is a decision for a qualified clinician.
Reconstitution
Reconstitute with bacteriostatic water. Usually comes as pre-formulated solution or requires reconstitution. The arithmetic is the same for any peptide: concentration = vial mg ÷ water mL, and on a U-100 syringe 100 units = 1 mL. Compute your own vial with the reconstitution calculator.
Half-life & cycling
Half-life: Varies. Half-life drives dosing frequency and how quickly the compound clears – see it plotted on the Thymalin half-life calculator.
Cycling
Initial course: 10 consecutive days. Maintenance: 2–3x per week for extended periods. Can be cycled 3–4 times per year.
Side effects & warnings
- an injection site that turns red, hot or hard, spreads, weeps, or comes with a fever – same-day medical care – research-grade material carries no sterility guarantee, so abscess and cellulitis are the documented consequence
- swelling of the lips, tongue or throat, trouble breathing, or widespread hives after a dose – emergency care
- • Generally well-tolerated
- • Minimal side effects
- • Mild injection site reactions possible
Research use only. Well-studied in Russia for immune support. May require intramuscular injection. Typically used in courses rather than continuously.
Tracking Thymalin in OptiPin
If you're tracking a Thymalin protocol, OptiPin logs each dose with reminders and site rotation, charts the outcome you care about over your dose timeline, keeps per-vial inventory with runout warnings, and (where relevant) does the reconstitution math – all on-device, no account.

What is Thymalin?
A thymic peptide that supports immune function and tissue regeneration. Extracted from calf thymus, helps normalize immune system activity.
What is Thymalin used for?
Commonly discussed uses include: immune system support, tissue regeneration, wound healing, anti-aging and longevity, autoimmune condition support, viral infection recovery. These are reported uses, not proven outcomes or a recommendation.
How is Thymalin dosed?
Commonly reported dosing: Injectable – 5–30mg injected intramuscularly daily for 10 days, then maintenance dosing 2–3x per week. This reflects patterns discussed in the community and is presented for information only, not as a dose recommendation – Thymalin is not an approved medicine and dosing should involve a qualified clinician.
How do you reconstitute Thymalin?
Reconstitute with bacteriostatic water. Usually comes as pre-formulated solution or requires reconstitution. On a U-100 syringe, 100 units = 1 mL. Concentrations vary by vial, so compute from your own vial with a reconstitution calculator.
What is Thymalin's half-life?
Varies. Half-life shapes how often it is dosed and how quickly it clears.
What are Thymalin's side effects?
Reported effects include: generally well-tolerated, minimal side effects, mild injection site reactions possible. Because it is a research compound, its safety profile is not fully characterized; discuss risks with a clinician.
