We’re shipping these in a box with 10mg per unit as the standard specification, and the model number on the label is P10 — usually 1 box is the minimum you can order right now, but confirm lead time for bulk quantities from China.
Most buyers go with the 5mg or 10mg depending on their batch protocols, and the purity holds at 99% by HPLC, which is better than reagent grade for this type of work as it cuts down on unknowns in sensitive assays.

Basically, this neuropeptide compound is intended for controlled lab use like neuroscience research, not for any in vivo appliction or human handling, and one thing a buyer might not ask is that opened samples need storage at 2–5°C while unopened vials are fine in cool, dry conditions for the full 2-year shelf life.
Also, we don't have a CAS number listed for this one — it’s pretty common with custom-order peptides, and the molecular formula is listed as N, which is a bit vague but matches what we’ve seen from the suppiler for this batch.

(We usually have stock, but confirm lead time as shipping can add 20 days or so to the UK, given the research grade standerd and origin in China.)
Anyway, 1 box typically contains enough for 10 to 15 assays depending on your dilution, and we don’t recommend this for high-throughput screening due to the packaging format.
