We typically quote around 15-18 weeks for first, though repeat orders come in faster once teh synthesis parameters are dialed in — it’s a pretty straightforward solid-phase process once we’ve run your sequence once. You’ll get a COA with every batch, and we include both HPLC and MS raw data as standdard, no upcharge.
Payment terms we prefer are 50% upfront with the balance on dispatch after QC clears, and we can do net 30 for established accounts with a history of clean payments. For international orders, we ship via cold-chain courier with gel packs and temperature loggers, though you’ll want to check import restrictions since this is strictly for research use and some customs offices get twitchy about peptide powders. Minimum order is usually 10mg or 100mg depending on sequence length — for anything under 10 amino acids, the 100mg MOQ applies, but for longer sequences (35+ residues), we’re more flexible.
Lead time from order confirmation to dispatch typically falls within 2-4 weeks, but if you need rush delivrey, our company can pull that down to 10 business days for an expediting fee of roughly 15% of the order total. Just confirm availability before placing the PO.
One thing procurement folks don’t always ask about is that we store finished lyophilized powder at -20°C before shipping — it’s not just the transport that matters, but the warhouse staging conditions during packaging. We’ve seen competitors ship from ambient storage, which cuts stability by 6 months or so.
Not great for high-throughput screening where you need constant room-temperture handling — but for most signal transduction or drug discovery work, the 2-year shelf life at -20°C is more than adequate.
We don't have a strict MOQ — we can handle gram to kilogram scale. For custom sequences, the minimum is typically 10 mg for feasibility, but just let us know your target quantity and we'll work from there.
Yes, every order comes with a COA that includes HPLC and MS analysis results. You'll get the purity data and mass spec confirmation for your batch.
Our standard range is 5 to 50 amino acids, but we can discuss longer sequences depending on complexity. For anything over 50, we'd recommend checking with our team first to confirm feasibility and lead time.
Lead time is usually 2 to 4 weeks from order confirmation. If you need it faster, we can sometimes rush small batches — just ask and we'll see what's possible.
Store the powder at -20°C or lower, away from moisture and light. When stored properly, it stays stable for at least 2 years. Avoid repeated freeze-thaw cycles after reconstitution.
Went smoothly with the shipping process, which was surprisingly fast for a bulk order. The peptides arrived securely packaged, showing no signs of damage during transit. Quality-wise, the products appear consistent and well-manufactured, meeting our expectations for research-grade materials. Customer service was responsive and helpful in addressing a minor query before finalizing the order. Overall, a reliable experience that makes reordering appealing.
