Lyophilized MUST BE RECONSTITUTED
TB-500 Peptide, also known as Thymosin Beta 4 or TB-4, this synthetic peptide mirrors the natural protein Thymosin beta 4, offering researchers a promising avenue for exploration. With properties akin to its natural counterpart, TB-500 may play a role in inducing angiogenesis, accelerating wound healing, and even influencing aspects like tumor cell metastasis and hair growth.
This 43 amino acid-containing peptide boasts high solubility in water and a lightweight structure. Abundant in wound fluid, particularly in the company of multiple blood platelets, TB-500 holds the potential for anti-inflammatory effects. It may not only support neurological healing but also contribute to the healing processes in critical areas such as the spinal cord, heart, and dermis research.
Why Buy TB-500 (Thymosin Beta-4) from BioPure Peptides
Proudly Made in the USA
BioPure TB-500 is proudly made in the USA, supporting consistent manufacturing oversight and high process standards. When sourcing a peptide like TB-500 / Thymosin Beta-4 (43 amino acids), domestic manufacturing is a key differentiator for customers who care about traceability and quality control.
Exceeding 99% Purity
Our TB-500 peptide exceeds 99% purity, which is a major quality benchmark in the peptide industry and a top search intent for shoppers comparing suppliers (“TB-500 99% purity”, “high purity TB-500”, “Thymosin Beta-4 43aa”). High purity helps reduce unknown variables and improves consistency from vial to vial and batch to batch.

Research Data Has Shown:

Research explores TB-500’s role in muscle cell movement and regeneration pathways, which is why it’s commonly discussed in studies related to post-exercise recovery and soft-tissue repair.

TB-500 is frequently examined in connective-tissue research focused on collagen organization and structural repair, making it relevant to joint and mobility-related research.

Studies investigate how thymosin-based peptides interact with inflammatory signaling pathways, supporting interest in TB-500 for managing tissue stress and inflammation balance.

TB-500 is studied for its involvement in angiogenesis (new blood vessel formation), which is essential for delivering oxygen and nutrients during tissue recovery.

Research involving dermal tissue and skin structure has examined TB-500’s influence on cell migration and repair signaling, linking it to skin recovery and regeneration interest.

TB-500 appears in studies focused on nerve cell movement and repair mechanisms, including pathways relevant to brain, spinal, and peripheral nerve tissue models.

Some research explores thymosin beta-4–related peptides in hair follicle signaling and growth cycle regulation, which has driven interest in TB-500 within hair and scalp studies.
