TB 500 by Dragon Pharma
What Is TB 500?
TB 500 by Dragon Pharma is a 5 mg lyophilized vial of thymosin beta-4, the peptide usually referred to in the sports world as TB-500. Thymosin beta-4 is a naturally occurring protein fragment involved in cell migration, tissue repair and the regulation of actin, and research interest around it centers on recovery of muscle, tendon and ligament tissue after injury or heavy training.
Athletes and researchers turn to TB 500 during high-volume training blocks, rehabilitation windows and off-season phases where staying mobile matters more than raw size. It is described in user reports as supporting faster recovery, less stiffness and better movement quality across joints and connective tissue, which is why it is often grouped with BPC-157 in recovery research.
Dragon Pharma supplies TB 500 as a lyophilized peptide for reconstitution with bacteriostatic water and subcutaneous injection. It is not a steroid and it does not build muscle directly; its place in research is structural support and recovery.
TB 500 Research Use
TB 500 research protocols follow a two-phase pattern: a loading phase that builds tissue levels over the first weeks, then a maintenance phase. Doses are referenced in milligrams, and the Dragon Pharma vial holds 5 mg of peptide.
| Phase | Dose | Schedule |
|---|---|---|
| Loading (weeks 1-4) | 2.5 mg per injection | Twice per week (5 mg weekly) |
| Maintenance (week 5+) | 2.5 mg per injection | Once per week |
| Reconstitution | 1-2 ml bacteriostatic water | Swirl gently, do not shake |
| Vial math | 5 mg per vial | One vial per week in loading |
| Route | Subcutaneous injection | Rotate sites, standard peptide practice |
Reconstitution
TB 500 is sometimes run daily at very small doses instead of in the twice-weekly loading pattern, but the loading plus maintenance model is the one most often referenced. Reconstituted peptide is kept cold and used within a standard peptide window, with fresh, sterile technique for every draw.
TB 500 Stacks
TB 500 is most often paired with tissue-repair and recovery peptides in what the community calls a healing or recovery panel. All partners below are Dragon Pharma products.
| Stack partner | Role in the stack |
|---|---|
| BPC 157 | The classic tissue-repair partner of TB 500 |
| BPC-157 5 mg / TB-500 5 mg (Blend) | Both peptides in a single reconstitution |
| GHK-CU 50 mg | Skin, tendon and tissue-support research peptide |
| CJC-1295 no DAC/Ipamorelin 10mg | GH-pulse support around recovery blocks |
| Sermorelin | Milder GH support for longer research phases |
| DSIP 10 mg | Sleep quality for tissue repair |
| Bacteriostatic water | Sterile reconstitution of the lyophilized vial |
The best known combination is TB 500 with BPC-157, commonly described in research circles as a complementary approach to joint and connective tissue recovery. Each peptide is reconstituted separately and dosed on its own schedule.
TB 500 Side Effects
TB 500 has a light reported side-effect profile compared with hormones, but it is a research peptide and deserves the same care as any injectable.
- Injection site: mild redness or soreness is possible; rotate sites.
- Dizziness or fatigue: occasionally reported, usually transient.
- Immune modulation: thymosin peptides interact with immune signaling, so caution applies for anyone with autoimmune conditions.
- Redness and flushing: reported by a minority of users after dosing.

What is TB 500?
TB 500 is the sports-world name for thymosin beta-4, a peptide studied for tissue repair and recovery. Dragon Pharma supplies it as a 5 mg lyophilized vial for reconstitution.
What is TB 500 used for?
Research interest centers on muscle, tendon and ligament recovery, plus movement quality and joint comfort during heavy training. It is a structural-support peptide, not a muscle builder.
What is the TB 500 dosage?
Reference protocols use a loading phase of about 2.5 mg twice per week, followed by a maintenance phase of 2.5 mg once per week. The Dragon Pharma vial holds 5 mg of peptide.
How do you reconstitute TB 500?
Add 1 to 2 ml of bacteriostatic water to the 5 mg lyophilized vial and swirl gently until dissolved. The solution is kept cold and measured with an insulin syringe.
How often do you inject TB 500?
The standard pattern is twice per week during a loading phase and once per week for maintenance. Some researchers instead run small daily doses, but twice weekly is the common reference.
How long does TB 500 take to work?
Recovery peptides act gradually. Users typically report that soreness and stiffness ease over several weeks of consistent dosing rather than after a single injection.
What are the side effects of TB 500?
Reported effects are mild and uncommon: injection-site soreness, occasional dizziness or fatigue, and flushing. Because thymosin peptides touch immune signaling, autoimmune conditions are a reason for caution.
Can you stack TB 500 with BPC 157?
Yes, it is the most common recovery stack. BPC 157 and TB 500 are studied on related but distinct pathways, and many researchers run them together on separate schedules.
Is TB 500 a steroid?
No. TB 500 is thymosin beta-4, a peptide related to tissue repair and recovery. It has no anabolic-androgenic activity and does not work through androgen receptors.
