What we're paying for is the consistency across batches — the peptide comes in as a, >99% on HPLC, and that's what keeps teh data clean in the long run, so I don't have to chase purity issues mid-study.
It's a GLP-1 receptor agonist, CAS 910463-68-2, molecular weight just over 4113 g/mol, and molecular formula is pretty standerd for this class — C187H291N45O59 — storage has to be at -20°C or below, which is typical but we had to verify our freezer capasity (usually manageable).

They sent a COA with each batch, and the HPLC trace matched the spec sheet, so no surprises there, and the mass spec data confirmed the peptide backbone, which is what you'd expect, but it's good to have it on file for audits.

We ordered 10, but the packaing is customizable — you can get 2mg, 5mg, or 10mg vials depending on your dose range, and we went with the 5mg because of that it's easier to reconstitute in smaller volumes for our assays.

Basically, most buyers in the UK go with the 99% purity for metabolic studies or weight management research, and this suppiler gets it to us within 12 business days or so, but check lead time if you need it faster.
It's not for in vivo use in humans — strictly for research — and the shelf life is about 24 months when stored properly, but we usually rotate stock to use it within 6 months to avoid any degradation risk.
Our standard MOQ is one box of 10 vials, but we can customize packaging quantities based on your order volume. Just let us know what you need.
Lead time is typically 7-10 business days for stock orders, and we can expedite if you're in a rush. Custom packaging may add a few extra days.
Yes, every batch comes with a COA confirming the >99% purity by HPLC, along with other quality specs. We can share it before you order.
Absolutely, -20°C or below is ideal for long-term stability. Just keep it in a sealed, moisture-free container to maintain the white powder form.
Sure, we offer customizable packaging options. You can specify the vial count per box, and we'll adjust the packaging to fit your needs.
Brisk delivery service ensured my order arrived ahead of schedule, which was a pleasant surprise. The packaging was secure and professional, preventing any damage during transit. Communication from the supplier was prompt and helpful, addressing my queries efficiently. Overall, a reliable experience that I would recommend to others.
