At Sinopep (Hangzhou Nuotai), we synthesize and supply pharmaceutical-grade peptides for research, diagnostic, and scientific applications. Every vial ships with a verified Certificate of Analysis (COA), and every batch is tested for purity before it leaves our facility.
TB-500, one of the most extensively researched synthetic peptides in regenerative biology, is available right now in our USA online shop — with standard delivery in just 2–3 business days and same-day express shipping for qualifying orders.
Let’s get into everything you need to know about TB-500, its documented research benefits, and why Sinopep is the most reliable peptide dealer in the USA for your supply needs.
What Is TB-500?
TB-500 is a synthetic peptide fragment derived from the naturally occurring protein Thymosin Beta-4 (Tβ4) — specifically the actin-binding domain (amino acids 17–23). The full sequence is:
Ac-Lys-Gly-Gly-Ala-Lys-Lys-Gly-Glu-Glu-Asp-NH₂
(Note: this reflects the active fragment; TB-500 = Tβ4 fragment 17–23)
Key Specifications:
| Property | Details |
|---|---|
| Full Name | Thymosin Beta-4 Fragment (17–23) |
| CAS Number | 77591-33-4 |
| Molecular Formula | C₂₁H₃₆N₈O₇S |
| Molecular Weight | 548.63 g/mol |
| Appearance | White lyophilized powder |
| Purity (Sinopep Standard) | ≥98% by HPLC |
| Storage | -20°C (lyophilized); +4°C short-term |
Thymosin Beta-4 is a 43-amino acid protein found naturally in virtually all human and animal cells. The TB-500 fragment is studied for its role in upregulating actin, a key protein in cell migration, tissue regeneration, and inflammation control.
The Science Behind TB-500 — What Research Shows
The body of peer-reviewed research on Thymosin Beta-4 and TB-500 is substantial and growing. Here’s a research-oriented breakdown of the most documented areas of investigation: TB-500 Peptide for Sale USA
1. Tissue Repair & Wound Healing
TB-500’s most well-documented action in preclinical studies is its ability to accelerate tissue repair through upregulation of actin polymerization. Actin is the structural protein responsible for cell movement and proliferation. By promoting actin organization, TB-500 facilitates faster migration of endothelial and epithelial cells to injury sites.
A landmark study published in the Journal of Investigative Dermatology demonstrated that Thymosin Beta-4 significantly accelerated wound closure in dermal wound models. Researchers observed increased keratinocyte and fibroblast migration, suggesting a direct role in cutaneous healing cascades. TB-500 Peptide for Sale USA

2. Anti-Inflammatory Signaling
TB-500 has been shown in multiple preclinical models to downregulate pro-inflammatory cytokines — particularly by inhibiting the NF-κB pathway, a central mediator of the inflammatory response. This makes it a compound of significant interest in chronic inflammation research models.
It does this without suppressing the immune system globally — a distinction that makes TB-500 particularly valuable in studies exploring localized anti-inflammatory mechanisms.
3. Angiogenesis (New Blood Vessel Formation)
One of TB-500’s most clinically compelling research areas is its documented role in promoting angiogenesis — the formation of new blood vessels. In ischemic tissue models, TB-500 administration was associated with increased vascular density and improved tissue perfusion.
This positions TB-500 as a compound of interest in cardiovascular repair research, peripheral vascular disease models, and post-ischemic recovery studies.

4. Musculoskeletal Repair Research
TB-500 is widely studied in the context of tendon, ligament, and muscle tissue repair. In rodent models involving induced muscle injury, TB-500 treatment was associated with enhanced myocyte migration, satellite cell activation, and reduced fibrotic scarring — all of which contribute to improved functional recovery.
5. Cardiac Tissue Repair
Perhaps the most remarkable area of TB-500 research involves cardiac regeneration. Studies using myocardial infarction models in mice demonstrated that Thymosin Beta-4 — and its active fragment — promoted the activation of cardiac progenitor cells and improved cardiac function post-injury.
This has generated significant interest among cardiovascular researchers exploring regenerative approaches to heart failure and ischemic cardiomyopathy.
6. Neurological Research Applications
Emerging research points to neuroprotective properties of TB-500. In models of traumatic brain injury and spinal cord damage, Thymosin Beta-4 has been associated with reduced lesion volume, decreased apoptosis in neural tissue, and improved behavioral outcomes.
While this field is still developing, it represents one of the most exciting frontiers in TB-500 research.
7. Hair Follicle Activation
A more recent line of research has examined TB-500’s potential role in hair follicle stem cell activation. Studies suggest it may promote stem cell differentiation in the bulge region of hair follicles — an area of active investigation for androgenetic alopecia research.
