VIAL

Freeze-dried powder in a sealed glass vial. Reconstitute with bacteriostatic water and administer via syringe. The most versatile and cost-effective research format.

RECONSTITUTION & SYRINGE REQUIRED

CARTRIDGE

Pre-filled and ready to administer. Slides into a reusable pen injector — no measuring or mixing required. Clean, discreet, and consistent across research protocols.

REQUIRES COMPATIBLE PEN INJECTOR

NASAL

Delivered via mucosal absorption — no needles required. A popular choice for research protocols where needle-free administration is preferred.

NEEDLE-FREE — SPRAY & GO

PEN

An all-in-one auto-injector with the cartridge pre-loaded. Dial, click, and administer. Optimal for high-frequency research protocols requiring precise, repeatable dosing.

DIAL, CLICK & INJECT — NO PREP

Vials are freeze-dried (lyophilised) powder — kept refrigerated unopened, they remain stable for up to 2 years.

Cartridges, nasal sprays, and pens arrive pre-filled as liquid, must be kept refrigerated at all times, and carry a Beyond Use Date — typically 4–8 weeks from receipt. Please refer to the BUD on the label.

Accelerates wound/tendon/ligament healing, anti-inflammatory

TB-500 (also known as Thymosin Beta-4 or TB-4) is a synthetic peptide that replicates the active sequence of thymosin beta-4, a naturally occurring protein involved in actin sequestration and cellular motility. This research compound has attracted substantial scientific attention for its potential roles in wound healing and tissue regeneration studies. Preliminary investigations indicate that TB-500 may facilitate cell migration, support angiogenic processes, and modulate inflammatory responses. Researchers employ this peptide in laboratory environments to explore mechanisms of tissue repair, particularly in models of dermal, corneal, cardiac, and musculoskeletal injuries. As a research-grade compound, TB-500 is designated solely for in vitro and animal studies. Scientists appreciate its capacity to enhance knowledge of actin-regulated regenerative pathways.

Research Applications

Musculoskeletal and Soft Tissue Regeneration
Preclinical studies demonstrate that TB-500 markedly accelerates the healing of muscles, tendons, ligaments, and skin wounds. It enhances cell migration and actin dynamics, improving tissue remodeling and flexibility in injury models.
Wound Healing and Dermal Repair
TB-500 promotes re-epithelialization and collagen deposition in cutaneous wounds. Research has examined its potential in accelerating closure of chronic ulcers, pressure sores, and corneal injuries while minimizing scar formation.
Angiogenesis and Vascular Support
TB-500 stimulates the formation of new blood vessels through upregulation of pathways involving VEGF and endothelial cell differentiation. This process is essential for nutrient delivery and oxygenation in ischemic or damaged tissues.
Cardiovascular and Neuroprotective Effects
Investigations reveal its contributions to cardiac repair post-injury and protection of neural tissues. Studies suggest potential benefits in myocardial recovery and reduction of oxidative stress in brain models.
Anti-Inflammatory Properties
It suppresses pro-inflammatory mediators, downregulates cytokines, and promotes resolution of inflammation, shifting toward pro-regenerative cellular environments.

Storage & Handling

Lyophilised vials are stable at −20°C for up to 2 years unopened. Once reconstituted, refrigerate at 2–8°C and use within 28 days. Avoid repeated freeze-thaw cycles.

Beyond Use Date

Pre-filled formats (cartridge, pen, nasal) carry a beyond-use date of typically 4–8 weeks from receipt. ≥98% purity by HPLC. For in vitro and preclinical research use only — not for human or veterinary use.
