You're looking at white lyophilized powder in sealed vials that hits ≥99% purity every time, backed by actual HPLC and mass spec testing on every batch — if you want the COA for any lot, just ask and it's yours without any pushback, which honestly is the kind of transparency I wish more suppliers offered.
Researchers working with linear or cyclic peptides use these mainly in controlled lab settings — you reconstitute the powder with water, but since it's non-sterile you'll want to handle it under a hood, and storing it at 2-8°C keeps it stable for months, though room-temperature handling for short stints works fine if you're careful about moisture.
Ordering repeats six months apart shows the same purity results, and that batch consistency matters more than most people think for longitudinal studies where variation could screw your data — tracking lot numbers and keeping the analysis reports is pretty standard if you're doing scientific investigation properly.
For payment we typically set up wire transfers or major credit cards, and shipping goes out within two business days provided stock is on hand — the molecular weight varies depending on which peptide you pick, but the sealed vials protect the lyophilized product during transit, so damage is rare.
For procurement, the key thing is the COA documentation you can request online or offline for any order, and supply chain runs consistently enough that you don't hit surprises on delivery dates — just make sure your lab space is ready because handling requires a controlled environment due to the non-sterile status.
We typically require a minimum order of 5 vials per peptide to ensure proper handling and shipping. Bulk discounts are available for larger quantities, just reach out to us.
Yes, we include a CoA with every batch. It's available upon request if you need it before placing an order, just let us know which peptide you're looking at.
Keep them at 2-8°C in the sealed vials they come in. Once reconstituted, store at -20°C and use within a few weeks for best results.
Standard orders ship within 3-5 business days after payment clears. Rush orders can be expedited if you contact us directly.
No, the vials are not sterile. The product is lyophilized powder in sealed vials for stability, but it's intended for lab use only. You'll need to handle it in a controlled environment if sterility is required.
