What you are paying for with TB-500
TB-500 is a synthetic peptide corresponding to the active region of Thymosin Beta-4, a naturally occurring protein involved in actin regulation and cell migration. In research it is valued for its reported ability to travel systemically and reach tissue throughout the body rather than acting only at a local site. Because of that, the cost of TB-500 reflects more than raw material. TB-500 research focuses on its binding to G-actin and its role in cell migration, blood-vessel formation, and the recruitment of repair cells to damaged tissue. By promoting cell motility, it is studied as a driver of slower but deeper regeneration than localized repair peptides.
What drives TB-500 pricing
Three things move the price of TB-500 most. First, vial size: TB-500 is cataloged in 5 mg vial, 10 mg vial, and a larger vial holds more peptide, so it costs more per unit even at the same per-mg rate. Second, purity and testing: genuine third-party verification to a 99%+ target with a Certificate of Analysis is a real production cost, and it is what makes a research result trustworthy. Third, quantity: ordering TB-500 in bulk or on a recurring research schedule lowers the effective per-vial cost.
Cost per milligram
Comparing peptides on price alone is misleading because vial sizes differ. The fair comparison is cost per milligram of verified peptide. When you evaluate TB-500, divide the vial price by its milligram content and compare like-for-like against other 99%+ third-party-tested material - not against unverified powder that happens to be cheaper.
Getting the best value on TB-500
TB-500 can be ordered as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months), and bulk or standing-order pricing is available for research programs. The best value is not the lowest sticker price - it is the lowest cost per milligram of documented, third-party-tested TB-500, which is the standard every Peptides Factory Direct lot is held to.
Frequently asked questions
How much does TB-500 cost?
TB-500 typically ranges from $45 to $130 per vial at research-market pricing, depending on vial size. All Peptides Factory Direct TB-500 is third-party tested to a 99%+ purity target with a COA on request. Research use only.
Why does TB-500 pricing vary between suppliers?
Differences come down to purity and documentation. Material with genuine third-party COAs, lot tracking, and identity confirmation costs more to produce than unverified powder. The fair comparison is cost per milligram of verified peptide, not sticker price.
Is cheaper TB-500 a good deal?
Not if it lacks a Certificate of Analysis. Across the research-supply market the strongest trust signal is verifiable third-party purity testing. Unverified TB-500 can cost far more in failed experiments than the few dollars it saves.
Can I get bulk pricing on TB-500?
Yes. TB-500 is available for one-time or recurring research orders, and bulk or standing-order pricing is available for research programs - note it on your order or open the portal.
