Actually ran into this exact line of research peptides last week when a lab was looking for something with tighter specs than what they'd been getting from their usual suplier—we've got the Retatrutide, Oxytocin, and Mots-C all at ≥99% purity as white crystalline powder, and endotoxin level comes in under 0.1 EU/mg which matters more than most buyers realize for sensitive cell work.
What it does is give you a clean starting point for dose-response studies or binding assays without worrying about degradation products skewing your data, and the molecular weight varies by peptide obviously since they're different compounds but our company can provide the exact figures on each COA if you need them for your calculations.
Storage is pretty straightforward at 2-8°C protected form light—we've had clients leave vials on the bench for a couple hours without issues but you'll want to get them refrigerated within 20 minutes or so for best stability, and the shelf life is 24 months when properly stored which is better than some comparable products we've seen.
Not ideal for anything involving long-term room temperture exposure or repeated freeze-thaw cycles once reconstituted, and the water solubility means you'll want to reconstitute with sterile water or saline depending on your protocol.
Each vial comes sealed under inert gas with sterile filtration already done, so you don't have to worry about sterility on your end, and we usually have stock on the 5mg and 10mg sizes but teh 25mg vials might need a lead time check (usually 2-4 weeks).
Yes, we include a Certificate of Analysis with every shipment that shows the ≥99% purity, endotoxin level <0.1 EU/mg, and mass spec verification. Just request it with your order.
Our MOQ is typically 10 vials per peptide, but we can discuss smaller trial quantities for first-time buyers. Just reach out and we'll work something out.
Each peptide is sealed under inert gas in sterile vials, double-bagged, and shipped with ice packs in insulated containers to keep the 2-8°C storage condition intact during transit.
We can synthesize custom sequences or modifications, but standard Retatrutide (CAS 2381089-83-2) ships as listed. Custom orders require a lead time of 2-4 weeks and a higher minimum quantity.
For stocked items like Retatrutide, Oxytocin, and Mots-C, we usually ship within 3-5 business days after order confirmation. Larger or custom orders take longer, which we'll confirm upfront.
