A quick word from the lab
So — why TB-500 (Thymosin β4 Acetate)?
Look, you've got a shortlist and you're comparing suppliers. Fair. Here's the honest pitch: TB-500 (Thymosin β4 Acetate) is one of the most-requested reference standards on our bench, and the reason people keep coming back is boring — it's the paperwork. Every vial ships with a batch-specific Certificate of Analysis: HPLC trace, mass-spec confirmation, water content, endotoxin where relevant. If the numbers on the CoA don't match what's on the label, we don't ship it.
What you're actually paying for
The vial is the cheap part. What costs money is the assay work behind it, the cold-chain handling, and a UK lab that will actually answer the phone if something looks off in your data. You're not buying a powder — you're buying a reference standard you can defend in a method-validation review.
Why buy it from the UK
No customs hold, no duty surprise, no parcel sitting in a Rotterdam warehouse for three weeks. Order before 2 pm on a working day and it leaves our facility the same afternoon, tracked. If a vial arrives damaged, we reship — no argument, no forms.
