The 99% purity is where it really counts for research accuracy—anything less and you're chasing ghosts in your data, and we acheive that consistently with pharmaceutical grade standdard.
That 4813.5 g/mol molecular weight makes it a heavy peptide, so solubility isn't always a given, but it's soluble in water at 10 mg/mL, which is actually a pretty good spec for this class of compound.

Most buyers go with the 10mg or 15mg vials for standard dose-response work, but we've got custom sizes form 2mg up to 50mg per vial if your protocol needs something different—just tell us the range.

Storage at 2-8°C is critical, and we've shipped enough to know that if the cold chain breaks during transit, you'll see degradation within 20 days or so—confirm your handling before ordering.

This isn't suited for any in vivo work beyond basic metabolic research, by the way—the GIP affinity is high, but it's not a simple GLP-1 analog, so don't assume it behaves the same way.
our company can do private labeling on the vials, but lead time varies (usually 2-4 weeks), and minimum order is roughly 50 units or so depending on the size you pick.
Our MOQ is typically 100 vials, but we can work with you on smaller quantities for first-time orders. Just contact us with your needs.
Yes, we include a COA with every batch showing ≥99% purity and other specs. Third-party lab reports are available upon request.
Store it at 2-8°C in a fridge and keep it protected from light. This keeps the powder stable for its intended use.
Yes, we offer custom sizes. Just let us know the specific mg per vial you need, and we'll accommodate it within our production capabilities.
Standard lead time is 7-10 business days after order confirmation and payment. Larger custom orders may take a bit longer.
