So you're looking at tirzepatide for dual-pathway metabolic studies, and the 4813Da structure means you're working with one of teh larger peptides—reconstitution needs care to avoid aggregation, and we typically ship it as a in 5mg, 10mg, 20mg, or 30mg vials (the 10mg is what most buyers go with for initial dosing curves).
Purity runs above 99% confirmed by HPLC, which is tighter than reagent grade for this—usually enough to minimize off-target effects in GLP-1/GIP receptor work, though you'll still want your own COA to verify the batch since we've seen minor variability in residual solvents on rare occasions.
What it does is hit both GIP and GLP-1 receptors in a single molecule, which basically cuts need to co-administer two separate compounds—useful for studying energy metabolism or appetite pathways without the complexity of multi-peptide mixing, but it's research use only, not suited for anything near clinical or human work.
We ship 10 in insulated containers with gel packs, and after reconstitution it's got to sit at 2-8°C or the peptide degrades quickly—within 14 days or so you'll notice reduced activity if you leave it out. The CAS number is 2023788-19-2, not something you'll find on every suplier's catalog so confirm it matches your POs.
Lead time is typically 10-14 business days for standard orders, though we've had backlogs on the 20mg and 30mg vials before so check stock first. One detail you might not think to ask: the lyophilized cake can look slightly off-white on humid days—that's normal, but if it's yellowed or broken, flag it immidiately.
We typically require a minimum order of 10 boxes (100 vials), but we can discuss smaller quantities for first-time buyers depending on stock.
Lead time is usually 7-14 business days after order confirmation, as long as we have the 4813Da batch ready. Rush orders may be possible with prior arrangement.
Yes, each batch comes with a CoA showing HPLC purity results, molecular weight verification, and appearance details. Just request it with your order.
Once reconstituted, keep it at 2-8°C in a fridge. It's stable for up to 28 days under those conditions—don't freeze it.
We can do custom fill sizes for larger orders, but the standard packaging is 10 vials per box with those four dosages. Minimum for customization is 500 vials.
