Best Price TB-500 Peptide | 99% Purity | Custom Dosage & Vial Sizes Available

What we've seen over the years is researchers needing a consistent, high-purity peptide for angiogenesis and wound-healing studies without the hassle of batch variations throwing off your data, and TB-500 is pretty much the go-to for that kind of work since it mimics natural thymosin beta-4 sequence.

We handle this with a straightforward white powder that runs ≥99% purity by HPLC—so you're not fighting impurities that mess with cell behavior—and we've got it in everything from a standdard 2mg vial up to a 5g bulk, and in my experience most buyers go with either teh 10mg or the 20mg sizes for most in vitro work, which basically saves you reconstitution time.

The sequence is Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH (CAS 885340-08-9), and it's stored at 2-8°C—you'll get a solid 2 years or so shelf life if you keep it sealed—and the grade is pharmaceutical, which means tighter tolerance on endotoxins than what you'd get from a crude synthetic, though it's absolutely not suited for human use at all (strictly research only).

We usually have stock on the common vial sizes and can customize packging—vials, bottles, boxes, whatever—but for the 1g or 5g bulk formats the lead time can stretch to 20 days or so since we do those on request with a fresh lyophilization run, so just confirm timing if you need it fast.

Also, one thing we've noticed is that the 30mg vial is actually easier to handle for serial dosing because you're reconstituting less often, but the 5mg is better if you're only testing a few wells—it's not ideal for high-throughput screening unless you buy the bulk and aliquot yourself.
