TB-500 (Thymosin Beta-4) by Dragon Pharma

TB-500 is Dragon Pharma's formulation of a synthetic fragment of Thymosin Beta-4 at 5mg per vial — a naturally occurring peptide involved in cell migration, tissue repair and reducing inflammation throughout the body. Unlike localised peptides, TB-500 works systemically, supporting recovery across multiple tissue types regardless of injection location.

What Is TB-500?

TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring protein found throughout the body's tissues and involved in actin regulation — a process central to cell movement and tissue repair. By promoting cell migration to damaged areas, TB-500 supports the body's natural repair processes across tendons, ligaments, muscle and skin. Its systemic action means it works throughout the body from a single injection, rather than being concentrated at the injection site.

Effects and Benefits

  • Systemic tissue repair support across tendons, ligaments, muscle and skin
  • Anti-inflammatory effects that may support recovery from training-related strain
  • Improved flexibility reported by some users over the course of a protocol
  • Works throughout the body regardless of injection site, unlike localised peptides
  • No suppression of natural testosterone — does not require Post Cycle Therapy

Dosage and Administration

Phase Typical Dose Frequency
Loading phase 2–2.5 mg Twice weekly for 4–6 weeks
Maintenance phase 2–2.5 mg Once weekly, ongoing as needed

TB-500 is typically used with an initial loading phase of twice-weekly injections for 4-6 weeks, followed by a maintenance phase of once-weekly dosing if continued support is desired. Unlike BPC-157, injection site location is less critical for TB-500 due to its systemic mechanism — subcutaneous injection anywhere convenient is generally considered effective.

Side Effects

TB-500 has a favourable safety profile with minimal reported side effects:

  • Injection site reactions are possible but generally mild, and less location-dependent than localised peptides
  • No impact on testosterone, estrogen or the HPG axis — does not suppress natural hormone production
  • No PCT required — can be used during AAS cycles, during PCT, or independently at any time
  • As with all peptides, product sourcing and proper reconstitution matter for integrity and consistency

TB-500 vs BPC-157 + TB-500 Blend

Dragon Pharma offers TB-500 both standalone and as a pre-combined blend:

TB-500 alone is well suited to users specifically following its loading-then-maintenance protocol, or whose recovery needs are systemic rather than centred on one localised injury. The blend is more practical for users wanting both systemic and localised support without managing two vials.

Reconstitution and Storage

TB-500 is supplied as a lyophilised powder requiring reconstitution with bacteriostatic water before use. Add the bacteriostatic water slowly along the vial wall and swirl gently — do not shake. Store the reconstituted vial refrigerated at 2-8°C, stable for approximately 28-30 days. Never freeze a reconstituted peptide vial. Calculate the exact reconstitution volume based on your intended dose before adding the bacteriostatic water.

"TB-500 is formulated as a high-purity 5mg Thymosin Beta-4 vial, supporting the systemic recovery protocols our customers run alongside their training and recovery routines."

Stacking and Related Compounds

TB-500 is often combined with:

  • BPC-157 for localised recovery alongside TB-500's systemic action
  • Dragontropin (HGH) for users combining direct GH elevation with peptide-based recovery support
  • Cypionat 250 or other testosterone bases as part of a broader cycle this recovery peptide supports

TB-500 works systemically — its effects occur throughout the body regardless of injection location. BPC-157 works most effectively when injected near a specific injury site, providing localised healing. They address recovery from complementary angles.

The loading phase typically runs 4-6 weeks with twice-weekly injections of 2-2.5mg. After loading, a maintenance phase of once-weekly dosing is common if continued support is desired.

Less so than for BPC-157. Because TB-500 works systemically, subcutaneous injection in any convenient location is generally considered effective, rather than needing to target a specific injury site.

Some users report improved flexibility over the course of a TB-500 protocol, which may relate to its anti-inflammatory effects and support for tissue repair, though individual experiences vary.

Standalone TB-500 suits users following its specific loading-then-maintenance protocol, or whose recovery needs are primarily systemic. The blend is more practical for users wanting both systemic and localised support without managing two vials.

No. TB-500 does not affect testosterone, estrogen or the HPG axis. It can be used during AAS cycles, during PCT, or independently at any time without requiring its own hormonal recovery protocol.
