Look, I'll be upfront with you — this isn't one of those peptides you can just freeze-thaw carelessly or handle outside controlled conditions because its solubility in water is pretty marginal (slightly soluble) and it really does need -20°C storage with light protection, which most buyers already know but it's worth emphasizing so you don't lose precious materail.
We've had labs running metabolic pathway studies with this stuff for about six months now and they consistently report clean HPLC results at 99%+ purity, which basically means minimal interference form truncated sequences or side products when you're doing your glucose regulation or weight control assays.
It's got a solid 3833.2 g/mol molecular weight and we test using HPLC, MS, and amino acid analysis for each batch — I usually send the COA with the shipment so you can see the chromatogram yourself, and arrives in sterile glass vials at whatever size you need from 8mg up to 30mg.
Lead time is roughly 10-14 working days for stock sizes or so if you're ordering standdard quantities, but if you need custom packaging or a larger bulk order just give us a heads up and we'll confirm the timeline because sometimes the MOQ shifts depending on how much we have on hand.
That said, it's definitely better than reagent grade for this kind of research since production follows GMP standards from synthesis through lyophilization, though I should mention it's not suited for anything beyond in vitro or animal model work — strictly research use only, no clinical or human application, and we'll include the SDS for safety documentation.
Most buyers go with the 10mg or 15mg vials (actually easier to handle when reconstituting) and the diacid-C20 modification plus the γ-Glu-AEEA spacer in the sequence is something we see a lot of questions about — it gives it decent stability in DMSO for long-term storage.
We don't have a fixed MOQ — you can order as few as one vial for research purposes. Bulk discounts apply if you need larger quantities.
Lead time is usually 3-5 business days for standard orders. Expedited shipping is available upon request.
Yes, we include a COA for every batch, covering HPLC purity (≥99%), MS identity, and amino acid analysis. Third-party testing reports are available too.
Reconstitute with sterile water or DMSO to your desired concentration. Store at -20°C, protected from light, and avoid freeze-thaw cycles.
We can accommodate custom vial sizes and packaging within our GMP facility. Just let us know your specific requirements when ordering.
Zippy delivery was the first thing that impressed me; the package arrived well ahead of schedule, which is always a major plus. The packaging itself was exceptionally secure, with no signs of tampering or damage, ensuring the contents were perfectly protected. Regarding the product quality, the vials were impeccably sealed and clearly labeled, reflecting a high standard of pharmaceutical handling. The supplier’s service team was remarkably responsive and professional, promptly addressing my pre-shipment inquiry with clear and helpful information. Overall, this experience was seamless from order to receipt. The combination of rapid logistics, evident quality control in presentation, and courteous, efficient customer support makes this supplier highly reliable. I felt confident throughout the entire process and would certainly consider future orders based on this positive transaction alone.
Very impressive experience overall. The shipping was remarkably fast, arriving several days ahead of the initial estimated schedule. The packaging was exceptionally secure and professional, with all vials intact and properly labeled. Regarding the product itself, the physical quality appears outstanding; the vials are clean, the powder looks pristine, and the labeling is clear and accurate. Communication from the supplier was consistently prompt, polite, and informative, answering all pre-purchase inquiries thoroughly. The ordering process on the website was straightforward and hassle-free. While this is a transaction for research materials and not for human use, the overall professionalism exhibited in logistics, product presentation, and customer service correspondence sets a high standard. The attention to detail in securing the shipment for transit was particularly notable. This level of service and apparent quality in the supplied intermediates fosters significant confidence. For any future requirements for research peptides or pharmaceutical intermediates, this supplier will undoubtedly be the primary consideration. The entire process, from inquiry to delivery, was seamless and executed with obvious expertise.
Hands down, the delivery was incredibly fast and well-packaged, which I truly appreciate. However, the overall service felt a bit rushed and could have been more attentive to my specific needs. On the bright side, the quality seems solid based on initial impressions, though I haven't tested it thoroughly yet. Hoping for more consistent communication in the future to make the experience smoother.
Wow, the delivery was incredibly fast and well-packaged, ensuring everything arrived in perfect condition.
