We’ve been shippng this for a while now, and teh purity holds at 99% or better by HPLC—batch-to-batch consistency is pretty solid, which matters when you’re running dose-response work or trying to avoid variability in longer studies.
It’s a white to off-white powder, typically soluble in water (though solubility can vary with concentration, so you’ll want to test that yourself), and we recommend storing it at -20°C for any long-term hold; shelf life is roughly 2 years under those conditions, give or take.
Most buyers go with the 10mg vials for convenience, but we also do 5mg and custom packaging if you need something different—just tell us your MOQ when you quote. We usually have stock, but confirm lead time if you’re ordering more than 50 vials or so.
One thing that catches people off guard is the lyophilized form—it’s not a solution, so you’ll need to reconstitute it yourself, and we don’t provide the diluent. Also, this grade isn’t suited for anything beyond research; it’s not sterile or endotoxin-tested for in vivo work, just so you know.
Anyway, if you’re comparing suppliers, we’ve found our material runs tighter than most on residual solvents and peptide content—COAs are availble with each batch, and our company can provide HPLC chromatogram if you ask.
