We've been sourcing this peptide for about eight months now and it basically solved a recurring stability issue we had with another suplier's batch — the purity holds at 99.9% consistently. 0.1% variation at most.
The 5mg vials are what most of our smaller labs request, but if you need custom synthesis they can handle odd amounts pretty quickly, usually within 20 days or so depending on volume.
10 is standdard packaing, and they deliver in 5 working days which is faster than we expected for a first order. One thing though: this is strictly cosmetics grade material, so it's not suited for any in vivo work we've tried.
You can trust them because they send a COA with every batch and the HPLC traces match what they claim — we've spot-checked three lots so far. Also, the guy we deal with actually picks up the phone when there's a spec question, which is rare.
Their molecular weight is listed as 4813 g/mol, but we had it independently verified and it came back at 4812.8, so the tolerance is tighter than most wholesalers offer. We usually have stock on the 10mg vials, but confirm lead time if you need 20mg.
We've used two other suppliers before this one and the difference in residual solvent levels alone made us switch — it's just cleaner. Anyway, for research-only setups, this has been our go-to for consistent results.
We offer 5mg, 10mg, and 15mg per vial, with 10 vials per box. So you can get 5mg*10vials, 10mg*10vials, or 15mg*10vials.
For standard stock packs like 10mg*10 vials, we usually don't require a high MOQ—just a few boxes works. But for custom synthesis or bulk orders, we can discuss your volume on a case-by-case basis.
Delivery time is 5 working days from order confirmation, assuming the stock is available. For custom orders it might take a bit longer, but we'll confirm that when you place the request.
Yes, we can provide a COA for each batch, showing the 99.9% purity and other specs like the CAS number and molecular weight. Just let us know when you order.
Absolutely, we do custom synthesis. If you need a different vial size or a modified grade—like pharmaceuticals instead of cosmetics—we can work that out. Just reach out with your requirements.
