Your custmer pulls this from the -20°C freezer, reconstitutes it in sterile water, and doses it by HPLC-verified concentration—no guesswork on the 10mg per vial claim when the COA shows the actual peptide content.
We run HPLC, MS, and amino acid analysis, not just spot checks, and you'll get the docs with teh shipment (usually within 2-3 days of order). 99% purity or better is our standdard, but we've seen it come in at 99.3% on most runs—tight tolerance for this molecular weight.
Solid-phase synthesis is what we use, and it's pretty much the for peptides this size—4109.6 Da is a beast to fold correctly, but we've dialed in the coupling efficiency over the years. One thing: don't expect this to hold up at room temp for more than a few hours; it's strictly -20°C and light-protected.

MOQ is 50 vials for custom labels, but if you need a smaller trial run, we can do 20 vials at the same price per vial (check lead time). Payment is net 30 for established accounts, or wire transfer upfront for first-time buyers—no letters of credit.
The sterile glass vial packaging is fine for most labs, but we've had a few buyers ask for larger formats—like 50mg or 100mg vials—which we can do on custom order with a 4-week lead time. Not ideal if you're scaling up fast.
Anyway, the GMP certifcation means the facility is audited, but it's research use only—don't try to push this through any clinical or human application, because of that it's not formulated for that and documentation won't support it.
Our MOQ for custom Retatrutide is typically 10 vials, but we can adjust depending on your project needs. Just let us know your required quantity, and we'll work with you.
Lead time is usually around 2-3 weeks from order confirmation, including synthesis, purification, and QC testing. Rush orders may be possible if we have stock of the peptide.
Yes, every batch comes with a Certificate of Analysis that includes HPLC, mass spectrometry, and amino acid analysis results. You'll get full documentation to verify purity and identity.
Absolutely, we can offer custom labels, vial sizes, or even multi-vial kits. Just specify your requirements, and we'll tailor the packaging to fit your research setup.
Store at -20°C, protected from light, just as specified. The shelf life is 24 months under those conditions, so keep them frozen and sealed until use.
