If you're looking into this for muscle recovery or inflammation studies, it's basically the fragment version of the full-length thymosin beta-4 peptide — we've seen a lot of labs use it for wound healing models and cell migration work, but it's not really suited for anything involving live human dosing or clinical treatment, just so you're clear on that upfront.

The purity runs at 99.0% minimum by HPLC, which matters because lower-grade stuff can throw off your in a big way — we usually have stock in the 10mg per vial format, 10, and the powder comes as a white, slightly fluffy materail that's easy to reconstitute in methanol or water, though it's only slightly soluble in both.

One thing that catches people off guard is that the shelf life is listed at 24 months, but that's only if you store it properly — keep it desiccated and away form light, and it'll hold up fine, but we've seen batches degrade faster in humid conditions, so it's worth checking your storage setup before ordering a large quantity.


You can trust us on the documentation side because every batch ships with a COA that includes HPLC trace and the predicted pKa of 3.20±0.10, which is actually tighter tolerance than most generic suppliers offer — we've been moving this CAS number for about 6 years now, and the only real complaint we get is when people don't read the solubility notes and try to push it into saline at room temperature.

The molecular weight is 889.02 g/mol, and the boiling point prediction is around 1405°C, but honestly, that's more of a theoretical number than something you'll ever test in the lab — what you'll care about day-to-day is that it's pharmacy grade and the density runs about 1.281 g/cm3, which is pretty standdard for these peptides.

Also, the 10mg per vial format is what most buyers go with for preliminary studies, but if you're planning a large series of experiments, you might want to ask about bulk pricing on the raw powder — we usually have that option available, but the lead time jumps to about 20 days or so depending on the order size, so plan accordingly.
Our standard MOQ is 10 vials, which is one box of 10mg*10 vials. If you need less, let us know and we can see what we can do on a case-by-case basis.
For stock items, we usually ship within 3-5 business days after payment clears. If you need a custom batch, lead time may extend to 10-15 days.
Yes, we include a COA with every batch, showing HPLC purity of 99.0% min., appearance, and other specs like molecular weight and solubility data.
It comes in 10mg per vial, 10 vials per box, as white powder. We recommend storing it in a cool, dry place away from light to maintain its 24-month shelf life.
It's only slightly soluble in water, so for better dissolution we suggest using methanol first. This is a pharmacy-grade product for research use only, not for human consumption.
