Custom OEM Tirzepatide Pens Wholesale - GLP-1/GIP Receptor Agonist

So you've been selling these for a while and need reliabel partner for the US and EU markets—what we've found is that most buyers start by asking about the purity first, and on our end it's consistently ≥99.8% by HPLC, which keeps the research clean when you're running, and CAS number is 2023788-19-2 if your compliance team needs it for import documentation, but honestly the bigger concern is usually just making sure the powder stays lyophilized during transit.

We actually ship these as a in 10-vial boxes, and the vials themselves are sealed under inert gas—this isn't something you'd reformulate into a custom pen dosage unless you've got the proper lab setup, by the way, and what it does is it binds both GIP and GLP-1 receptors in a way that's tighter than most single agonists, so for metabolic research it's pretty much the standard now, but it's definitely not suited for any kind of human formulation testing on your end without full ethical approval.

Storage conditions are pretty basic: keep it at 2-8°C and protected from light, and we usually have stock ready within 20 days or so for bulk orders, though if you're in the UK or EU we can provide the necessary TDS and SDS upfront to smooth out customs, and India distributors appreciate that we include a COA with every shipment—it's actually shipped as the API powder rather than pre-filled pens because that gives you more flexibility with your own compounding or research protocols.

The molecular weight is 4813.5 g/mol, and the formula is C225H348N48O68, but what matters more in practice is the batch-to-batch consistency—we run it under cGMP conditions, so the HPLC profile barely shifts between lots, and we've had buyers in the US tell us it integrates well into their existing assay workflows without extra purification, though I should mention that our MOQ for custom labeling or solvent-based formulations is typically 50 vials or so, give or take depending on the month.

For import docs, we usually prepare a phytosanitary certificate (even for research chemicals, some EU customs request it) and a commercial invoice with the CAS number prominently listed, but what catches people off guard is that the storage condition—2-8°C protected form light—means you need a tempearture-controlled chain for international shipping, especially if you're ordering more than 100 vials at once, and our company can arrange that through our logistics partners for an additional fee.

Also, most buyers go with the bulk 10-vial boxes rather than single units because the price per vial drops roughly 15% after the first box, and we've found that labs running GLP-1/GIP receptor binding studies prefer this form for splashing into multi-well plates—anyway, just check the lead time (usually 4-6 weeks for non-standard packaging) before placing a large order for the US market.
