We've been shiping this SS-31 and Retatrutide blend for about a year now, and most buyers come to us after running single-peptide assays first—they want to see if the combination changes the mitochondrial response curve in their metabolic models, and it usually does, though teh 10mg vial is enough for preliminary screening if you're just testing solubility and baseline viability.
The lyophilized powder is white, pretty much what you'd expect, and it reconstitutes clean in saline within a minute or so—no cloudiness, which is a good sign for peptide integrity, but you'll want to keep it at -20°C until you're ready, and after reconstitution it's stable at 2-8°C for maybe 20 days depending on how careful you are with sterility.
Purity is >99% by HPLC, and we include the COA with every order—some buyers ask for the MS data too, which our company have on file, but we don't always send it unless you request it, and honestly the HPLC trace tells you what you need for most mitochondrial work.
Bulk pricing kicks in at 30mg or more, but we usually stock 10mg and 20mg vials for single-lab projects, and if you need 50 units or so we can do a custom run with about 2 weeks lead time—just confirm before you place the order because synthesis schedule can shift.
One thing buyers don't always think to ask is that this blend isn't ideal for in vivo work if your model has poor peptide stability—it's really designed for cell-based assays where you control the enviroment, and we've seen some labs push it into rodent studies with mixed results, so we flag that upfront.
Also, the CAS number 736992-21-5 covers the SS-31 component specifically, not the blend, so if your purchasing system needs a single CAS for the mix you'll have to use a custom identifier—our company can provide a product code that works for most ERP setups, but it's worth checking with your compliance team first.
We don't have a strict MOQ — you can order as little as a single 10mg vial. That said, bulk discounts kick in at 50 vials or more.
Standard orders ship within 3–5 business days. If you need expedited shipping, just let us know and we can often cut that to 1–2 days.
Yes, every shipment includes a COA with HPLC and MS data showing purity >99%. We can also share the raw spectra if you need deeper validation.
We can customize vial sizes for bulk orders — just tell us your target dosage and we'll adjust. For smaller quantities, we stick to the standard options.
Keep it at -20°C in the original vial, away from light. Once reconstituted in water or saline, it's stable for about a week at 2-8°C — never freeze it after mixing.
