The 99% purity is really what sets it apart, and once you've handled a few batches you can see the difference in how clean it runs on HPLC—most supliers don't maintain that tolerance consistently batch to batch.
We typically store it at -20°C in teh foil bag it ships in, and we've found it's stable for about 2 years or so if you don't freeze-thaw it repeatedly; basically, just pull out what you need and put it right back.
For ordering, MOQ is 1 gram or 1 box, which is pretty reasonable for a research setup, and we usually have stock but confirm lead time (2-4 weeks) since can vary.
Some labs try to use this in cell culture applicaion where it's not really intended. It's best kept to in vivo or ex vivo research protocols—I've seen it crystallize in some buffer systems, so watch your reconstitution method.
The molecular weight is about 2224 g/mol, so it travels nicely in solution but doesn't cross membranes well, which is a limitation you'll want to factor into your dosing strategy.
Our MOQ is 1 gram or 1 box, whichever you prefer. We keep it low so research labs can start without over-committing.
Yes, every batch comes with a COA showing the 99% purity and other specs. Just request it with your order.
Keep it at -20°C in the sealed foil bag or box. Stored properly, it stays stable for 2 years.
Yes, it's produced in a GMP-certified facility to ensure consistent quality for research use.
We package in foil bags or boxes, and can customize based on your quantity. Just let us know your preference.
Yikes, the shipping was incredibly slow and took far longer than the estimated delivery window. Tracking information was sparse and not updated regularly, which was quite frustrating when waiting for an important research supply. However, once the package finally arrived, the product itself was securely packaged and the vial was intact. The quality of the lyophilized powder appears to be good upon visual inspection; it was a fine, uniform powder with no signs of moisture or clumping, which is promising for our laboratory standards. Communication from the supplier was minimal, and responses to inquiries about the shipment delay were generic and unhelpful. While the product seems to meet basic quality expectations for research-grade material, the overall experience was significantly marred by the poor logistics and lack of proactive customer service. For time-sensitive projects, this level of service is not acceptable. The order did eventually arrive complete and as described, but the process to get there was needlessly stressful. Future orders would depend heavily on whether they can demonstrably improve their shipping reliability and customer support responsiveness. The core product is adequate, but the surrounding service elements need substantial improvement to be considered a reliable bulk supplier for ongoing research needs.
Great experience overall. The shipping was surprisingly fast and the package arrived well-sealed and secure, which is crucial for sensitive research materials. Communication was prompt and professional whenever I had questions. The product itself, the lyophilized powder, arrived in perfect condition with no signs of degradation or damage. The quality appears to be exactly as described for research-grade material. The service was efficient and straightforward from ordering to delivery. I am satisfied with this transaction and would consider this supplier for future needs. The entire process was handled smoothly without any complications or delays.

Yikes, the shipping was incredibly slow and took far longer than the estimated delivery window. This caused a significant delay in my research timeline, which was quite frustrating. However, once the package finally arrived, the product itself was securely packaged and appeared to be of acceptable quality for research purposes. The communication from the supplier was minimal, which didn’t help with the anxiety over the delayed shipment. While the peptide vials were intact and the labeling was clear, the overall experience was marred by the logistical issues. I hope they can improve their shipping partners or processes in the future to provide a more reliable service for time-sensitive scientific work. The basic quality seems fine, but the service aspect, particularly regarding logistics updates, needs considerable enhancement to meet the expectations of researchers who operate on strict schedules.
