So a researcher pulls a 10mg vial from the fridge after thawing it slowly at room temp—about 20 minutes or so—then reconstitutes it in sterile water for subcutaneous dosing in an obesity study, and they need that purity to be consistent across every injection.
We typically verify every batch by HPLC and MS, so you’re looking at ≥99% purity confirmed on the COA before it ships, and dissolves readily in water or buffers without any visible residue.
Also, storage is straightforward: 2-8°C in a dry, dark cabinet keeps it stable for 24 months, but you’ll want to avoid freeze-thaw cycles once it’s reconstituted—that tends to degrade the peptide faster than the spec sheet suggests.
Availble sizes run form 2mg up to 30mg per vial, and most buyers go with teh 15mg for longer, while the 5L drum is easier to handle for smaller pilot runs.
One thing we don’t mention on the label: the vials come sealed with desiccant under inert gas, so if you’re working in high-humidity labs, that extra gas layer really helps when opening multiple vials over a week.
We usually have stock for the common sizes, but confirm lead time for the 30mg vials—those can be about 20 business days out if we’re between.
We can supply as little as a single 2mg vial for research purposes, so there's no strict MOQ on that size. For larger sizes like 30mg, we typically ask for a minimum of 5 vials per order.
Yes, we include the calculated molecular weight on the certificate of analysis, which is provided with each batch. The sequence information is available upon request for verified research institutions.
Absolutely, every batch of Retatrutide undergoes HPLC for purity and mass spectrometry for identity verification. You'll receive a COA with the results, including the ≥99% purity confirmation.
Keep it in the original sealed vial with desiccant, stored at 2-8°C in a dry place away from light. Avoid repeated temperature changes—take out only what you need and return it to cold storage quickly.
We offer standard sizes of 2mg, 5mg, 10mg, 15mg, and 30mg in sealed vials. For custom aliquoting or specific buffer reconstitution, we can arrange that for larger orders—just let us know your requirements.
Excellent service from start to finish! The shipping was incredibly fast, arriving much sooner than expected. The packaging was secure and professional, ensuring the product remained intact. Communication was prompt and helpful, with clear updates provided throughout the process. I'm thoroughly impressed with the overall experience and would highly recommend this supplier.
