Thymalin (10 mg vial)
Once daily intramuscular protocol for immune research.
Thymalin is a thymic extract from the Soviet bioregulator program, used clinically in Russia for immune support, with short courses and long gaps as the traditional format. The protocol below follows that structure intramuscularly.
Quick answer: at the standard 10 mg + 1 mL reconstitution, a 10 mg dose of Thymalin draws 100 units (1.0 mL) on a U-100 insulin syringe, once daily intramuscular.

Protocol overview
Dosing & reconstitution
Frequency: Once daily intramuscular
Typical duration: 10-day courses, repeat every 3-6 months
Reconstitution: 10 mg vial + 1 mL bacteriostatic water = 10 mg/mL. Units below are for a U-100 insulin syringe at this concentration.
| Phase | Dose | Units per injection |
|---|---|---|
| Days 1-10 | 10 mg | 100 units (1.0 mL) |
Units = (dose ÷ concentration) × 100 on a U-100 syringe. Change the vial size or water volume and the calculator redoes all of this for you.

Thymalin dosing — what the literature actually supports
We publish a schedule when there is a citable human source and we say so when there is not. Filling this space with a number nobody measured would make the page look more complete and be worth less than nothing to you.
Reconstitution and measurement
This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre. Common vials for Thymalin: 10 mg.
- Wipe the stoppers of both vials with an alcohol swab and let them dry.
- Draw the bacteriostatic water with a sterile syringe and inject it slowly down the inside wall of the peptide vial — never straight onto the powder.
- Swirl gently until the solution is clear. Do not shake; foaming and agitation damage peptides.
- Label the vial with the date and concentration, and refrigerate at 2–8 °C protected from light.
Worked example at the calculator defaults: 10 mg + 2 mL of bacteriostatic water = 5 mg/mL, so on a U-100 insulin syringe 1 unit = 50 mcg of Thymalin. Change either input and the calculator redoes this for you.
Storage and stability
Supplies math
Whatever amounts your research uses, the planning arithmetic is the same. The calculator runs all of this per compound.
Supplies by protocol length
Based on the maintenance dose above (10 mg, once daily intramuscular) and a 10 mg vial reconstituted with 1 mL.
| Duration | Injections | Vials | Syringes | Bac water | Swabs |
|---|---|---|---|---|---|
| 8 weeks | 56 | 56 x 10 mg | 62 | 6 x 10 mL | 112 |
| 12 weeks | 84 | 84 x 10 mg | 93 | 9 x 10 mL | 168 |
| 16 weeks | 112 | 112 x 10 mg | 124 | 12 x 10 mL | 224 |
Syringe count includes ~10% spares. Swabs = 2 per injection (stopper + site). Vial count assumes the full maintenance dose for the entire duration.
Important notes
Practical considerations for consistency and safety.
- Use a new sterile insulin syringe for each injection and dispose in a proper sharps container.
- Rotate intramuscular injection sites (deltoid, vastus lateralis, gluteus medius) and use the appropriate needle gauge for the muscle.
- Inject slowly and steadily; wait a few seconds before withdrawing the needle to ensure complete delivery.
- Administer at the same time each day for consistent levels. Setting a daily reminder helps maintain the schedule.
- This compound lacks controlled human safety data. Start with the lowest reported amount and increase gradually while monitoring for any adverse reactions.
- The 10 mg vial size is standard for this compound. Reconstitute with 1 mL bacteriostatic water for a convenient concentration.
How Thymalin works
A polypeptide complex extracted from calf thymus, rather than a single defined peptide. It sits in the same Russian bioregulator tradition as the Khavinson compounds and is used there as an immune-restorative.
Benefits & side effects
Potential benefits
- Thymic extract supporting immune function
- Supports T-cell maturation and immune regulation
- Short course protocol with long breaks
- Used clinically in some countries
Possible side effects
- Injection site reactions (IM)
- Mild fever possible
- Short courses with long breaks for safety
- Limited Western clinical data
This list reflects published literature and community reports. Individual responses vary. Not medical advice.
Bloodwork worth tracking
The community-standard practice is a baseline panel before starting, a recheck 8 to 12 weeks in, and another after time off. For Thymalin, the markers most worth watching:
CBC with differentialCMPCRP
Typical time off: 3-6 mo between courses
Lab panels are how a research protocol stays honest: numbers move before symptoms do. Interpretation belongs with a clinician. Not medical advice.
Lifestyle factors
None of the literature above was run on a background of poor sleep and no protein. These variables move outcomes more reliably than any compound on this site.
- Protein in the 1.6 to 2.2 g/kg range preserves lean mass through any body-composition phase.
- Resistance training 2 to 4 days per week plus 150+ minutes of weekly aerobic work reinforces whatever the protocol is doing.
- Sleep is the recovery window: 7 to 9 hours at consistent times.
- Hydration matters more than usual on compounds with GI or flushing effects: 2 to 3 liters daily.
- Track the variables that matter: weigh-ins, measurements, photos, and labs at sensible intervals.
Subcutaneous technique and practical notes
General best practice from clinical injection guidance — the same fundamentals nurses are taught, none of it specific to any compound.

Quick answers
How many syringe units is a 10 mg dose of Thymalin?
At the standard reconstitution of 10 mg with 1 mL bacteriostatic water (10 mg/mL), a 10 mg dose draws 100 units (1.0 mL) on a U-100 insulin syringe.
How do you reconstitute Thymalin?
Add 1 mL of bacteriostatic water to the 10 mg vial for 10 mg/mL. Inject the water slowly down the inside wall of the vial, swirl gently without shaking, and refrigerate at 2 to 8 °C after mixing.
How long does a 10 mg vial of Thymalin last?
About 1 maintenance doses of 10 mg, roughly 0.1 weeks at once daily intramuscular.
Does Thymalin have human trial data?
No published dosing literature exists for Thymalin. The amounts shown are community convention only.
How does Thymalin work?
A polypeptide complex extracted from calf thymus, rather than a single defined peptide. It sits in the same Russian bioregulator tradition as the Khavinson compounds and is used there as an immune-restorative.
Sourcing Thymalin
Whatever you are working with, the documentation matters more than the price. Ask for a batch certificate of analysis whose lot number matches the vial you actually receive — a COA for a different batch tells you nothing about yours.
