We're seeing the 5mg vials move faster than the 10mg lately, though most buyers go with the 10mg for longer protocols — it's basically same white powder, just different fill weights, and the CAS is 885340-08-9 for both, which you'd expect.
The purity runs at 99.99% or better by HPLC, and we test every batch before shiping, so you're not guessing about the C40H68N12O12 molecular weight of 909.04 g/mol being right. Storage is pretty straightforward: keep it at 2-8°C, away form light and moisture, and it'll hold for 18 months or so. We've had labs push it to 24 months with no degradation, but I wouldn't recommend that for critical assays. The 10mg vials come 10 to a kit, and we can do 15mg or 20mg if you need it, but the 30mg is a special order (usually 2-4 weeks lead time).
It's not suited for anything oral, obviously — this is injection-grade only, and the sequence Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH means it's got to be reconstituted properly with sterile water or bacteriostatic water. One thing buyers don't always think about: teh powder can clump if the vial seal gets compromised during shipping, so we double-bag each kit in foil pouches.
Actually, the 5mg is easier to handle for small-scale work since you don't waste as much reconstituting a 10mg vial for a single dose. We usually have stock on the 5mg and 10mg, but confirm lead time if you're ordering 50 kits or more — in batches of 1000 vials, and our company can't split those every time. The MOQ is 10 kits for standerd sizes, and we'll send the COA with every shipment, no extra charge.
Anyway, the 5L drum is easier to handle than the 10L if you're doing bench work, but for bulk reconstitution, the 10mg vials are better than the 5mg for consistency across replicates. We've seen some labs use it for wound healing models, and the 99.99% purity keeps interference down — tighter tolerance than most reagent-grade peptides you'll find elsewhere.
We offer flexible bulk orders, but the typical MOQ is 10 kits (each kit contains 10 vials). You can mix different vial sizes like 5mg and 10mg in one order.
Standard lead time is 7-14 business days after payment confirmation. For larger orders, we may need up to 20 days to ensure the ≥99.99% purity is maintained.
Yes, a COA is included with every batch, confirming the ≥99.99% purity and molecular weight of 909.04 g/mol. Just request it when placing your order.
We can customize vial sizes within the 5mg to 30mg range, as long as the total order meets our MOQ. For 25mg, we'd adjust the fill volume to match your spec.
Store them at 2-8°C in a fridge, away from light and moisture. Unopened vials should stay dry; once reconstituted, use within a few days to avoid degradation.
