We've been handling retatrutide for a while now, and most researchers we deal with are running GLP-1/GIP receptor studies where that dual agonism profile matters—it's basically what sets it apart from single-target peptides in the class, though it's not ideal for acute metabolic assays where you need a shorter half-life compound.
The 10mg fill is lyophilized, and we typically see 99% purity by HPLC with a consistent elution pattern—no odd shoulders on the chromatogram, which tells us the synthesis holds up batch to batch, and the mass spec confirms the expected molecular weight (roughly 4225 g/mol give or take) without any truncated sequences.
Storage is straightforward: keep the vial desiccated and away form light, unopened it's good for 2 years at room temp, but once reconstituted you'll want it at 2-8°C (we usually say 4°C or so) and use within a week—the peptide's pretty stable in solution, but repeated freeze-thaw will degrade it faster than you'd think.
MOQ on the standerd 10mg box is just 1 box so you can test a batch before committing, and we always include the COA with each order—the HPLC trace and MS data are right there, no need to chase us for it. For custom labeling or packaing, our company can do 10 to 50 boxes depending on the spec.
A detail that catches some buyers off guard: the PP foil bag inside the box isn't resealable, so once you open it, transfer the vial to a dry container or just use it straight from teh box—it's fine for a few days but don't leave it exposed to humidity.
Anyway, sample's avaliable if you want to run your own tests before a larger order, and we usually have stock ready to ship within a week.
It means you're getting a very consistent, high-grade peptide with minimal impurities, so your experimental data should be reliable and repeatable. Lots of researchers come back to us once they see how clean it runs.
Yes, samples are available. Just reach out and we can arrange a small trial so you can test the quality before committing to a larger customized batch.
Standard single-box orders usually ship within 1-3 business days. Customized ones take a bit longer, around 7-14 days, since we handle your specific packaging or labeling requirements.
Absolutely, we include a CoA with every shipment that shows the 99% purity and other test results. Just let us know if you need any additional quality documents beforehand.
It comes in a PP foil bag inside a box to protect it from light and moisture. Stored properly in a cool, dry place, it keeps its full potency for the 2-year shelf life.
