The >99% purity threshold verified by HPLC isn’t just a number — it means you’re not dealing with truncated sequences or acetate residuals that would skew your binding assays, and we run a full MS fingerprint alongside every batch so there’s no ambiguity in what you’re reconstituting.
What it basically comes down to is that we retest any lot if it’s been in storage past the 18-month mark, even though teh stated stability is 24 months at -20°C protected from light, and we’ll send you the updated COA before dispatch so you’re not guessing.
The white lyophilized cake is pretty consistent form vial to vial — we’ve seen less than 0.5% variance in mass across a typical production run — and most buyers go with the 5mg or 10mg aliquots rather than bulk powder because reconstitution errors get magnified with larger vials.
Non-sterile is actually the default for research-grade peptides, so if your protocol demands sterile filtration you’ll need a 0.22μm syringe filter (usually PES or PTFE) during reconstitution, and our company can point you to buffer recommendations if you ask.
We don’t do minimum order quantities on the sealed vials — you can order a single 5mg unit or 50 units or so, but the lead time jumps to about 20 days when we’re restocking from the lyophilizer, so confirm stock before placing a large repeat order.
Our standard MOQ is 10 vials per batch, but we can discuss smaller quantities for first-time research buyers. Just reach out to us.
Yes, we include a Certificate of Analysis with HPLC and MS data for every batch. You'll get the actual purity confirmation, not just a claim.
Store at -20°C in a freezer, away from light and moisture. Keep the vial sealed with the desiccant inside—once reconstituted, use it quickly and don't refreeze.
No, this is a non-sterile, research-grade powder. It's intended for lab use only, not for human or animal injection. You'd need to filter-sterilize it in a lab setting if required.
Absolutely, we can adjust vial sizes or pack larger quantities per vial for bulk research projects. Just let us know your preferred specs when ordering.
