We've had labs come to us after burning through expensive single-vial orders from smaller supliers — they're usually running on GLP-1 receptor activation and need consistent materail across dozens of replicates, so they reach for the 500mg or 1g bulk packs and we ship those within 5-7 working days (customs can add a day or two depending on the destination).

It's a with a molecular weight just over 4113 g/mol and purity north of 99.9% by HPLC — that's tighter tolerance than most research-grade peptides we handle, and the COA comes with every batch, though we recommend you run your own QC if you're doing in vivo work. CAS is 2381089-83-2, and the formula runs C187H291N45O59, but honestly most buyers just care about teh purity number and fact that it's been tested for endotoxins and residual solvents below 10 ppm.

Basically, this mimics GLP-1 to influence appetite and insulin signaling pathways, so it's used in obesity and diabetes research models — but it's not suited for anything beyond that, like cancer or neuro studies, because the receptor profile just isn't there. Some buyers ask about reconstitution buffers, and we usually suggest sterile water or PBS, but the lyophilized cake is stable for about 24 months at -20°C away form light and moisture.

Anyway, bulk pricing kicks in at 500mg and above — we usually have stock, but confirm lead time for custom vial sizes or ampoules. Most buyers go with the 10mg vials for smaller runs, but the 5g drum is easier to handle for large-scale work.
Yes, every batch comes with an HPLC certificate of analysis showing purity over 99.9%. We can share that with you before shipment.
For custom packaging, our MOQ is typically 100 vials per order. Smaller quantities are available in standard 10 mg vials if you're just starting out.
Standard lead time is 5–8 business days after payment confirmation. UK customs clearance usually adds 1–2 days, so total delivery is around 10 days.
It's stable at room temperature for up to 7 days during transit, but once received, store it at -20°C in a light-protected, moisture-free container to maintain the full 24-month shelf life.
Absolutely — each shipment includes a Certificate of Analysis, Material Safety Data Sheet, and a commercial invoice for customs. We also label everything as 'research use only' to stay compliant.
