Immune Protocol
ThymalinComplete Dosing & Administration Guide
Russian thymic peptide complex that rejuvenates immune function and supports healthy aging
Dose Range
5-10mg
Frequency
Once daily
Route
Intramuscular injection
Cycle Length
4-6 weeks
Dosing
How much
do I take?
Starting Dose
5 mg daily
Initial dose to assess tolerance and immune response; best for first-time users
Standard Dose
10 mg daily
Standard clinical protocol used in most Russian research studies; most effective dose
Advanced Dose
10 mg Thymalin + 5 mg Epitalon daily
Combined peptide protocol for enhanced longevity and geroprotective effects
Timing
Best time to take
Morning injection for consistency; no stimulant effects so evening is also acceptable
With food?
Can be injected with or without food; food does not affect absorption
If stacking
If combining with Epitalon, both can be injected at the same time or spaced 2-3 hours apart; use separate injection sites
Adjusting Your Dose
Increase if
- +Well-tolerated after 5 days at starting dose with no side effects
- +Seeking stronger immune response for illness prevention
- +Healthcare provider recommends standard or advanced protocol
Decrease if
- -Experiencing persistent injection site reactions
- -Low-grade fever lasts more than 24 hours
- -Unusual fatigue that doesn't resolve within 2 days
Signs of right dose
- ✓Improved energy levels within 1-2 weeks
- ✓Fewer colds and respiratory infections over following months
- ✓Better overall sense of vitality and well-being
- ✓Improved lab markers (T-cell counts, immune panels) if tested

Reconstitution
What you need
- •Thymalin lyophilized vial (10 mg)
- •Sterile water for injection or 0.9% sodium chloride (saline)
- •Sterile syringe (1-3 mL)
- •Sterile needle (25-27 gauge)
- •Alcohol swabs
Injection
Route
Intramuscular (preferred in clinical settings) or Subcutaneous
Best sites
- •Deltoid muscle (upper arm) for intramuscular injection
- •Gluteal muscle (upper outer quadrant) for intramuscular injection
- •Abdomen (2 inches from navel) for subcutaneous injection
- •Front of thighs for subcutaneous injection
Technique
- 1.Clean injection site thoroughly with alcohol swab and let dry for 30 seconds
- 2.For IM: Insert needle at 90° angle into muscle; for SC: Pinch skin and insert at 45° angle
- 3.Inject solution slowly over 5-10 seconds for comfort
- 4.Withdraw needle and apply gentle pressure with clean swab
- 5.Rotate injection sites daily to prevent tissue irritation

Safety

Safety Profile
Thymalin has an excellent safety profile based on over 40 years of clinical use in Russia. Most patients experience zero side effects, and the peptide complex has been described as 'practically non-toxic' in research literature. It has been used safely in thousands of patients, including elderly populations over extended periods.
Safety data comes primarily from Russian clinical studies and decades of medical use. While extensive within Russian medicine, Western randomized controlled trials are lacking. The long track record of use provides reassurance, though evidence quality by international standards is classified as 'limited human trials.'
Common Side Effects
Experienced by some users
No side effects in most patients
The majority of people using Thymalin experience zero adverse effects. Russian clinical literature consistently reports it as remarkably well-tolerated.
Management: Simply monitor how you feel during the course and keep a brief daily log of any changes.
Mild injection site reaction
Slight redness, warmth, or minor swelling at the injection site that typically resolves within a few hours.
Management: Rotate injection sites daily, use proper technique, and apply gentle pressure after injection. Ice can help if swelling occurs.
Less Common
- •Transient low-grade fever
- •Mild flu-like symptoms
- •Temporary headache
These typically resolve with continued use or dose adjustment.
Stop and Seek Help If
- ×Signs of allergic reaction (swelling, difficulty breathing, widespread rash)
- ×Persistent fever above 101°F that doesn't resolve within 24 hours
- ×Severe injection site reaction with spreading redness or signs of infection
- ×Your healthcare provider recommends discontinuation
- ×Completion of prescribed course (Thymalin is used in short courses, not continuously)
Always consult your healthcare provider before starting or stopping Thymalin. This information is for educational purposes and does not replace professional medical advice. Thymalin is not FDA approved and should only be used under qualified medical supervision.
Interactions
With other peptides
- ✓Synergistic combination — together they produce stronger longevity and anti-aging effects than either alone; the most studied Thymalin combination
- ✓Both support immune function through different mechanisms; combining is safe but may be redundant for some goals
- ✓Different mechanisms (immune vs healing); can be combined safely with separate injection sites
With medications
- !Corticosteroids - High-dose corticosteroids may reduce Thymalin's immune-stimulating effects; use together only under medical supervision
- !Immunosuppressants (tacrolimus, cyclosporine) - Thymalin may counteract immunosuppression; avoid combining without specialist guidance
- ✓Blood pressure medications - No known interactions; safe to use together
- ✓Antipsychotic medications - Studies show Thymalin enhances treatment outcomes when used alongside psychiatric medications
- ✓Antibiotics - Safe to combine; many clinical protocols use them together for infections
With supplements
- ✓Vitamin D - Complementary immune support; both work through different pathways; synergistic benefits
- ✓Zinc - Zinc supports thymic function; combining with Thymalin is highly recommended
- ✓Vitamin C - Antioxidant immune support; safe and complementary combination
- ✓Probiotics - Both support immune health through different mechanisms; safe combination
