Custom Tirzepatide 10mg Pharmaceutical Grade Peptide Supplier

A lot of the 10mg tirzepatide out there comes from facilities that can’t consistently hold 99% purity across batches—HPLC traces show tails you don’t want, and that variability cuts into your dose-response reproducibility. We’ve gotten complaints about that from labs running in vivo work where a couple percent impurity shifts everything.

What our company supply goes through a verified pharmaceutical-grade line with a 3-stage purification process, and the certificate on each lot shows a single sharp peak at 4813 g/mol—no shoulders, no degradation fragments. The white powder arrives sealed in a PP foil bag with desiccant, and it’s been stored at 2-8°C continuously from production to dispatch, which matters more than most buyers realize for long peptides like this.

CAS 2023788-19-2, molecular formula C225H348N48O68, and we’re holding ≥99% purity as standerd—not 98.5% that some suppliers round up. The 10mg dosage is fine for typical reconstitution volumes (usually 1-2 mL), and we’ll back COA with raw HPLC data if you need it for your audit trail. Actually, we also carry 5mg vials, but most buyers go with the 10mg for fewer reconstitution steps.

2-8°C storage in a dry environment is non-negotiable—we’ve seen room-temperature storage degrade this peptide within 14 days, so don’t skip that. The PP foil packging includes desiccant because (and this is a detail you wouldn’t guess) even brief humidity exposure during a lab move can introduce hydrolysis. We usually have stock ready within 3-5 business days, but for quantities over 100 vials, confirm lead time—it might stretch to 20 days or so.

This isn’t suited for anything beyond research applicaion; the formulation lacks stabilizers for clinical or compounding use, so don’t push it into those workflows. The molecular weight—roughly 4.8 kDa—isn’t trivial to handle in saline, so expect dissolution times around 2-5 minutes with gentle rotation, not instant mixing. Anyway, it’s tighter tolerance than most generic tirzepatide sources on the market, and the price per milligram beats reagent-grade options.
