Buy TB-500 Peptide (Thymosin Beta-4).

TB-500 Peptide (synthetic version of the endogenous protein Thymosin Beta-4) is a protein that is encoded by the TMSB4X gene. The protein consists of 43 amino acids (sequence: SDKPDMAEI EKFDKSKLKK TETQEKNPLP SKETIEQEKQ AGES) and has a molecular weight of 4921 g/mol.

Thymosin-β4 is a major cellular constituent in many tissues. Its intracellular concentration may reach as high as 0.5 mM. Following Thymosin α1, β4 was the second of the biologically active peptides from Thymosin Fraction 5 to be completely sequenced and synthesized.

Extracellular Thymosin beta-4 may contribute to physiological processes such as angiogenesis, wound healing, and regulation of inflammation. Scientific research has demonstrated TB-500 significantly helps in the healing of muscle, tendon, ligament, joint and bone injuries: TB-500 increases angiogenesis (new blood vessel formation) around damaged tissue, improves collagen deposition, tissue healing and cell survival.  It has the ability to control the upregulation cell-building proteins and promote cell growth, cell migration, healing and the proliferation of cells.

Peptides Prefer the Cold

Keep peptide vials refrigerated at all times to reduce peptide bond breakdown. DO NOT FREEZE. Most peptides, especially shorter ones, can be preserved for weeks if careful.

Always swab the top of the vial with an alcohol wipe, rubbing alcohol or 95% ethanol before use.

Before drawing solution from any dissolved peptide vial, fill the pin with air to the same measurement you will be filling with solution, ie. if you plan to take 0.1 ml, first fill the pin with 0.1ml of air, push the air into the vial, and then draw the peptide back up to the 0.1 ml marker. Doing so will maintain even pressure in the vial. Always remember to remove air bubbles from the pin by flicking it gently, needle side up, and pushing bubbles out. In addition, push out a tiny amount of solution to ensure there is no air left in the metal tip.


Only Mix With Sterile Bacteriostatic Water

The purity and sterility of bacteriostatic water are essential to prevent contamination and to preserve the shelf-life of dissolved peptides.

Push the pin through the rubber stopper at a slight angle, so that you inject the bacteriostatic water toward the inside wall of the vial, not directly onto the powder.

Lyophilized peptide should be stored at -20°C (freezer), and the reconstituted peptide solution at 4°C (refrigerated). Do not freeze once reconstituted.


Do Not Shake Vial To Mix

Air bubbles are unfavorable to the stability of proteins.
