Custom vial sizes and labeling are something we do pretty much all the time, so you're not locked into a standerd 50mg tube for this KPV peptide—just tell us what concentration or bulk synthesis you need and we'll adjust, and the white powder itself hits 99% purity with solubility at 5 mg/mL in water, which is actually better than some reagent-grade peptides for dissolving evenly.
Most researchers in neurobiology or inflammation studies go with the 10mg vial for smaller assays, but we've also had labs order 500mg batches for extended dose-response work (usually 2-4 weeks lead time on that), and the pKa of 13.00±0.70 means it holds up well in basic buffer systems—just keep it at -20°C sealed dry or you'll lose activity faster than expected.
It's not suited for anything beyond biological research—don't try it in cell-free systems with high salt concentrations because solubility drops off sharply past 5 mg/mL—anyway, we supply it as a dry powder in AR grade, so you're getting tighter tolerance than most generic peptide suppilers.
One thing a buyer might not think to ask: the powder can clump if exposed to humidity during reconstitution, so pre-warm vial to room temp before opening, and we usually have stock on the 10mg and 50mg sizes but confirm lead time for custom labels or bulk synthesis since that can vary.
Typical MOQ is 5 grams or so for custom orders, but for standard vials our company can do single units if you're just testing a batch first—COA comes with every shipment, and teh HPLC trace shows that 99% purity is consistent across lots.
MOQ for Semax is typically 1 gram, but we can discuss smaller quantities for research labs. Just reach out to confirm.
Yes, each batch comes with a COA showing HPLC purity and other specs like solubility and storage conditions.
Store it at -20°C in a dry, sealed container away from light. It's stable under those conditions for long-term use.
Standard lead time is 3-5 business days after payment, depending on stock availability. We can expedite if needed.
We can adjust packaging sizes or add custom labels for bulk orders. Let us know your requirements and we'll work it out.
