We're shipping this stuff to the US and EU regularly now, purity's verified at >99% by HPLC and MS with full COAs included—just request them with your PO, and we'll handle the import docs for you.
Most buyers go with the 10mg or 30mg vials for weight loss research, basically because lyophilized powder reconstitutes easily in water and holds up fine at -20°C protected form light, but teh 20mg is a solid middle ground if you're unsure.
The molecular weight of 4119.6 Da means it's a 34-amino acid peptide, and what it does is it's not suited for long-term storage at room temp—you'll want to keep it frozen (we usually have stock, but confirm lead time for larger orders).
It's GMP manufacutred and sterile filtered, non-pyrogenic, so you're looking at tighter tolerance than most generic peptides out there, though white to off-white appearance is pretty standard for this grade.
We've seen researchers pair this with metabolic studies pretty effectively, but one thing a buyer might not think to ask: the 30mg vial is actually easier to reconstitute if you're doing multiple runs, while the 10mg is better for single-use protocols.
Anyway, MOQ is 50 vials or so for standdard sizes, and we've got the TDS and SDS ready to go for customs clearance—just tell us which region you're shipping to.
It means you're getting a highly consistent peptide with minimal impurities, which helps reduce variables in your studies. Each batch is checked with three different methods to confirm the purity and identity.
We typically offer those four standard sizes, but for larger research projects we can discuss custom vial fills. Our MOQ for any order is just a single vial, so you can start small and scale up.
Most orders ship within 1-3 business days, and we always use insulated boxes with ice packs to keep the vials at -20°C during transit. We'll include a temperature logger if you need one.
You'll get a Certificate of Analysis showing HPLC, MS, and AAA results, plus a GMP certificate and a sterility test report. Everything is batch-specific and ready to share.
Once you reconstitute with sterile water or bacteriostatic water, it's best to use it right away or store at 2-8°C for short term. The powder itself is water soluble, so just a gentle swirl dissolves it completely.
