Basically, we’ve been moving this for a few years now and most buyers go with the 10mg vial because of that it balances cost and handling pretty well—the 5mg is fine for smaller runs but you end up ordering more often. It’s a that dissolves clean in water or buffers, and we’ve had labs confirm it stays stable for 24 months or so at -20°C away form light, which is longer than some other GLP-1 analogues we’ve stocked.
The purity is the main draw here, 99.9% or better by HPLC, and we run MS and amino acid analysis —usually takes us about 20 days from request to having the COA in hand. That matters because one buyer was getting inconsistent results with a competitor’s 98% matrial, and switching to ours tightened their noticeably. We don’t always advertise it, but the rubber-stoppered glass vials are sterile-filled, so you don’t have to worry about contamination during reconstitution if you’re careful.
Anyway, it’s not suited for anything involving human or animal use—strictly research only, and we make that clear on every invoice. Some folks ask if it’s better than reagent-grade retatrutide from bulk suppilers, and I’d say yes for pharmacological studies where consistent molecular weight (roughly 4300 g/mol) and tight purity specs actually affect your data. We usually have stock, but confirm lead time if you need more than 50 vials at once, (in most cases our company can ship within a week).
Storage is non-negotiable, and we’ve seen buyers who ignore the -20°C guideline end up with degraded peptide after four months—it’s just a fact that lyophilized powder will clump if it gets warm or sees light. One detail that catches people off guard: the CAS number 2381089-83-2 is specific to this sequence, so if you’re ordering from another source with a different CAS, teh structure might not match. We recommend keeping the vial sealed until it’s at room temperture to avoid condensation.
It’s not the cheapest option out there, but when you compare the documentation—HPLC traces, mass spec data, amino acid analysis all in one COA—it pretty much saves you headache of verifying purity yourself. And we don’t charge extra for the detailed COA like some distributors do (usually adds $25-50 elsewhere). That’s the real value for a research lab that needs traceable results.
So that’s the gist of it. Purity is verified, shelf life is solid if stored right, and the 24-month window gives you plenty of time to work through a batch.
We typically require a 10mg MOQ for this peptide, but smaller quantities may be available for first-time orders—just ask.
Orders are usually processed and shipped within 2-3 business days after payment confirmation.
Yes, every batch comes with a CoA including HPLC and MS data to confirm ≥99.9% purity and correct molecular weight.
Keep it at -20°C in the original vial, protected from light. Properly stored, it stays stable for up to 24 months.
Yes, we can supply in larger sterile glass vials or custom packaging—just specify your needs when ordering.
